Is hot yoga cool during pregnancy?

pregnant yoga

An article this year in Canadian Family Physician concludes that "…pregnant women should avoid practicing hot yoga during pregnancy." Have you ever had a pregnant patient ask you if she should use hot tubs, warm pools, use hot packs, exercise in the heat, or participate in hot yoga? As always, the answer to some of the questions may be "it depends," as many factors must be considered including the woman's age, fitness status, pre-pregnancy exercise routines, general health, level of risk, what part of the body she wants to expose to heat, and ability to modify the requested activity. And, most importantly, the biggest driving factors behind our response to our patients is this: is there any known risk for the mother and her baby, and what does her physician say? If there is any known risk to the mother and to the viability of her pregnancy, then we always want to err on the side of caution.

What about yoga? Can participating in a hot yoga class increase core temperature and put the growing fetus at risk? The linked clinical reference article above cites some of the following factors as potential reasons why a person should not participate in hot yoga during pregnancy.

•Elevated core temperatures can occur with fever, extreme exercise, saunas, and hot tubs

•First trimester hyperthermia may lead to neural tube defects, gastroschisis, esophageal atresia, omphalocele, and encephaly in the developing fetus

•Heat decreases time to exhaustion, potentially leading to over stretching, muscle and joint injuries

•High temperatures may increase the risk of dizziness or fainting due to effects on blood pressure

I can imagine the arguments from all sides of the story, and we know that, especially in a highly litigious society, a medical provider will always suggest the most conservative approach. When the stakes are inclusive of both a healthcare license and the maternal/fetal health of our clients, rehabilitation professionals must also be medically conservative and mindful of the most safe, and effective health practices. Several prior posts have discussed the benefits of yoga during pregnancy, and the article by Chan and colleagues acknowledges that for pregnant women participating in yoga the benefits can include increased quality of life, decreased stress and anxiety, decreased pain, and improved sleep. Is it reasonable, then, to suggest that a woman avoid hot yoga during pregnancy?

If you are wondering, "What would Ginger say?", you have another opportunity to learn yoga principles and techniques applied during pregnancy from our yoga expert, Ginger Garner. Ginger teaches from the perspective of a mother, a physical therapist, an athletic trainer, a community educator, a national-level speaker, and a professional yoga therapist. She will be teaching the continuing education course Yoga as Medicine for Pregnancy in November in New York.

Post-prostatectomy Candidates for Transobturator Sling Surgery

male sling

Surgery for prostate cancer can impair urinary function, and in the case of persistent urinary incontinence, patients may progress to surgical interventions. In order for physicians to conduct optimal patient counseling and surgical candidate selection for post-prostatectomy urinary incontinence (UI), the records of 95 patients were reviewed in this study. The patients were retrospectively placed into "ideal", n = 72, or "non-ideal", n = 23, categories based on chosen characteristics, and the results of their outcomes and satisfaction were consolidated. Men in the "ideal" group had the following characteristics: mild to moderate UI, external urethral sphincter that appeared intact on cystoscopy, no prior history of pelvic radiation or cryotherapy, no previous UI surgeries, volitional detrusor contraction with emptying of the bladder, and a post-void residual of < 100 mL. Patients who did not meet all listed criteria for the "ideal" group were placed into the "non-ideal" classification.

A cure for the surgery was considered total resolution of post-prostatectomy incontinence with the sling. Of the patients fitting into the ideal classification, 50% reported cure, and of the non-ideal group, 22% reported a cure. Satisfaction rates within the ideal group for the procedure were 92%, whereas the non-ideal group reported a 30% satisfaction. Although uncommon, complications occurring in both groups included prolonged pelvic pain and worsened urinary incontinence. The authors describe the importance of placing the correct amount of tension through the sling, and of leaving as much of the external urethral sphincter in place as possible. Another complication that occurred more frequently is that of acute urinary retention. In the ideal cohort, the 11 cases of urinary retention resolved within 6 weeks of surgery. Of interest is that 12 of the 23 men in the "non-ideal" category had to undergo further surgery with an artificial urethral sphincter.

This information can assist surgeons in guiding and advising patients about operative procedures for post-prostatectomy incontinence. (Ideally, every patient would "fail" a trial of pelvic rehabilitation prior to progressing to a surgery!) If a patient wishes to proceed with a sling surgery despite being in a "non-ideal" category, he could be advised of the known potential outcomes. This article offers support for pre-operative investigation techniques such as urodynamics. Our role as pelvic rehabilitation providers may allow us to discuss such research with patients and providers, and participate in discussions about the role of rehabilitation pre-operatively or post-operatively. If you would like to learn more about working with men who have pelvic floor dysfunctions, you still have time to book a flight to Orlando for the Male Pelvic Floor Function, Dysfunction, & Treatment course, where you can learn about male pelvic pain, incontinence and BPH, and male sexual dysfunction. This is the last opportunity to take this course this year!

Amy Robinson, PT, PRPC, CLT - Featured Certified Pelvic Rehabilitation Practitioner

In our weekly feature section, Pelvic Rehab Report is proud to present this interview with newly certified practitioner Amy Robinson, PT, PRPC, CLT.

Amy Robinson

What/who inspired you to become involved in the pelvic rehabilitation field?:

I first learned about pelvic rehabilitation while I was a student at the Indiana University Physical Therapy program. The instructor brought in speakers for special topics sessions and I must admit I knew at that moment that pelvic rehab was an area of interest for me. However, I was hesitant to start in the area of pelvic health as I felt I needed to gain experience as a new graduate, and I also wasn’t sure I would feel comfortable performing pelvic examinations. I chose to work in a hospital setting for one year, a long term care setting for 2 years, and then transitioned into outpatient physical therapy. There were numerous times in each of those settings that it was apparent pelvic rehabilitation was the missing link in the patients’ treatment plan. In 1998 we had a physician, Dr. Scott Miles, approach the president of the rehabilitation company that I worked for and request that they train a women’s health physical therapist. This was my opportunity and I took my first course with Kathe Wallace, PT. I remember thinking that she was a wealth of knowledge and her enthusiasm allowed me to get over the trepidation of performing pelvic examinations. She allowed me to focus on the examination process itself, how to apply critical thinking to the patient symptoms and evaluation findings, and how to pick the appropriate treatments. I was hooked! I feel very blessed to have had the opportunity to participate in several continuing education courses all over the country from so many very talented Pelvic Health Practitioners and each and every one of them have inspired me in some way to continue to learn and perfect my skills as a pelvic practitioner.

What patient population do you find most rewarding in treating and why?

I truly enjoy treating patients who have a diagnosis of pelvic pain. There are so many different types of pelvic pain and the complexity of the cases fascinate me. I thrive on working together as a team with my client to identify the issues at the root of their pain. There are no two pelvic pain patients who are alike which allows me to create an individualized plan for each patient. It is always very rewarding when a patient who has been suffering with pain for years meets their therapy goals, has the knowledge to self treat, and can complete ADLs and work functions, all being done without pain limiting them.

What role do you see pelvic health playing in general well-being?

Pelvic health affects women and men across the life span. The core musculature must activate correctly in order to maintain function. I continually explain to my patients that the pelvis is similar to the foundation of a house. If the foundation is not laid correctly in a house, the doors and windows don’t open and close as they should and the floors will not be level. In the pelvis if the alignment is not correct, the musculature and ligamentous systems cannot function optimally which leads to injury, pain, and an overall decrease in function over time. Pelvic health should be addressed on the medical history portion of the intake paperwork for all patients who attend physical therapy. If the medical history identifies potential issues with pelvic health, a referral should be made to a qualified pelvic practitioner.

What motivated you to earn PRPC?

I think it is critical in today’s market to be able to identify yourself as a practitioner who has taken the time and made the effort to truly understand such a complex area of the human body. Several years ago when Women’s Health became the hot topic, I noticed there were several hospitals and therapy companies that were sending Physical Therapists to one course and then marketing that they had a Women’s Health program. Unfortunately, this issue continues today and there are so many women and medical practitioners who feel that pelvic rehabilitation is a waste of time and money due to the poor outcomes they have had while under the care of unqualified pelvic practitioners. There are many days in my practice that I evaluate patients who on average have seen 10 different physicians and two pelvic practitioners and still have experienced little to no relief of their symptoms. I feel earning PRPC allows medical practitioners and potential clients feel more confident in my skill set.

Can We Predict Who Benefits from Manual Lymph Drainage?

 

digestive system

An interesting study assessed the ability of fluorescence imaging to measure the benefits of manual lymphatic drainage (MLD a key component of complete decongestive therapy (CDT). Lymphatic dysfunction, often developing into lymphedema, affects a significant population of our patients who undergo treatment for breast cancer or pelvic cancer. Complete decongestive therapy includes manual lymphatic drainage, compression bandaging, therapeutic exercise, and specific skin care techniques. A theory describing the beneficial effects of MLD, as explained in this article, is that MLD stimulates a contractile or "pumping" mechanism within the superficial lymphatic system.

Although effects of MLD can be measured by limb volume assessment, this study aimed to investigate if in fact contractile function is improved. The investigators used near-infrared fluorescence, or NIR fluorescence, to measure "…the apparent propulsive lymph velocities..and…the period or time of arrival between successive propulsive events." Twelve subjects diagnosed with Grade I or II unilateral lymphedema and 10 controls were included in this research and were treated by a certified lymphedema therapist. The manual lymphatic drainage preparatory protocol for an involved upper extremity included lymphatic massage to the cervical lymph nodes x 5 minutes, then the neck, axillary region of the contralateral arm, and the ipsilateral inguinal region. Lower extremity MLD also started at the neck, then treatment was directed to the contralateral inguinal nodes and ipsilateral axillary nodes. The control subjects received massage to the neck for 3 minutes, bilateral axillary region massage x 5 minutes or bilateral inguinal regions, depending on if the upper or lower limb was imaged in the study. The appropriate limb was then treated with MLD massage techniques.

Prior to and after the treatment, images were collected that allowed the researchers to visualize the imaging contrast agent that was injected through intradermal route into the patient's upper or lower extremities. The results of the study, although limited by statistical power by the low number of subjects, demonstrated that after the manual lymph drainage, in subjects and in controls, treatment had the potential to improve lymph transport. Despite the overall evidence of potential for improvement, there were two subjects in the upper extremity lymphedema group who did not show an improved lymph transport after treatment. One of these subjects also did not respond to MLD and bandaging treatment that followed for six weeks after the fluorescence study. In the lower extremity treatment group, overall apparent lymph velocity and a decrease in the period between propulsive events was noted. The authors state that NIR fluorescence could be utilized to help predict patients who may benefit from manual lymph drainage. The imaging may also help identify functioning lymphatic vessels towards which the therapist can direct manual techniques for draining the limb effectively.

While this study was directed towards the lymphatic dysfunctions of the limbs, what does a pelvic rehabilitation therapist need to know when treating dysfunctions of lymph in the pelvis? Lymphatic function can easily be interrupted following surgeries, or radiation for pelvic cancers, or even following orthopedic injuries. Join Debora Hickman at her continuing education course Manual Lymphatic Drainage for Pelvic Pain in San Diego next month to learn technique in applying MLD for the pelvis!

Supporting Medical Providers Who Care for Patients with Pelvic Pain

A recent on-line survey queried fourty-four Obstetrician-Gynecologists (OB-GYNs) in British Columbia to learn more about the needs of physicians who treat women who have endometriosis and chronic pelvic pain (CPP). Physicians reported that women who present with endometroisis or chronic pelvic pain usually require more visits than other patients, for reasons including medical and pain management, lack of a clear diagnosis, and lack of improvement in condition. Evaluation techniques utilized by the physicians often included laparoscopy and ultrasound, and despite these practices, the OB-GYNS reported challenges in making a diagnosis or successfully treating their patients with CPP. In fact, survey results indicated that 5% of the respondents were able to diagnose a patient for a cause of pelvic pain in > 70% of patients. Most of the physicians reported that less than half of the women treated had a good response to interventions. Although the highest rate of referral for these providers was to another OB-GYN specializing in pelvic pain, nearly 60% of the time a referral to physical therapy was reported.

Although some of the narrative comments encountered in this survey were positive, including one physician's report of having "…good success with physiotherapy…", more often the providers expressed frustration and annoyance when faced with not only the challenges of diagnosis and treatment, but also the poor compensation and the longer visits required for counseling and teaching of patients. In addition to wanting more clear guidelines on diagnosis and management of female CPP, physicians expressed interest in having group educational sessions for patients, and more resources such as educational brochures on self-management for patients.

How can pelvic rehabilitation providers fill in this knowledge gap? I recall asking a referring provider if he was pleased with his patients' rehabilitation outcomes, and he expressed such a relief that I was taking the "dregs of the practice." He meant nothing disparaging about the patients themselves, he explained, just that when these patients walked in the door he felt a sinking feeling because he did not know what to do for them. Now, he reported, these same patients were returning from a pelvic rehabilitation referral and excitedly reporting on progress they had made. So many physicians and other referring providers still do not understand the scope of the patient populations that we can treat in pelvic rehabilitation. We can provide a necessary bridge between the challenge of diagnosing and medically treating chronic pelvic pain and the rehabilitation approach that addresses the chronic pain issues. Differential diagnosis of chronic pelvic pain from a rehabilitation standpoint is a skill set that every therapist must continually improve upon. If you are interested in learning more about these skills, sign up for faculty member Peter Philip's continuing education course Differential Diagnostics of Chronic Pelvic Pain next month in Connecticut.

Balloon-assisted Training in Dyssynergic Defecation

Dyssynergic defecation occurs when the pelvic floor muscles (PFM) are not coordinating in a manner that supports healthy bowel movements. Ideally, emptying of the bowels is accompanied by a lengthening, or bearing down of the PFM, and with dyssynergia, the muscles instead shorten. Because a portion of the levator ani muscles slings directly around the anorectal junction (where the rectum meets the anal canal when the muscles are tight, the "tube" where the fecal material has to pass through narrows, making it difficult to pass stool. If emptying the bowels is difficult, patients will often strain for prolonged periods of time, an unhealthy pattern for the abdominopelvic area, and constipation may occur due to the stool remaining in the colon for prolonged periods of time, where the water is reabsorbed from the stool, becoming harder and more difficult to pass.

Can patients with this condition be helped by pelvic rehabilitation providers? Absolutely, with correction of muscle use patterns, bowel re-training education, food and fluid recommendations, and pelvic muscle rehabilitation addressed at optimizing the muscle health. Much of the time, patients with this dysfunctional muscle use pattern present with tension and shortening in the pelvic floor muscles, although they may also present with muscle lengthening and weakness. Surface electromyography (sEMG a form of biofeedback, has also been utilized and the literature supports sEMG for bowel dysfunctions including dyssnergia.

Another technique used by pelvic rehabilitation providers for re-training dyssynergia (also known as non-relaxing puborectalis, or paroxysmal puborectalis, naming the muscle fibers that sling around the rectum) is the use of balloon-assisted training. In this technique, a small, soft balloon is inserted into the rectum and is attached to a large syringe that will inject either water or air into the balloon, causing the balloon to enlarge within the rectum. This training technique allows the patient to provide feedback about sensation of rectal filling including when the patient perceives urges to defecate. The patient can practice expelling the balloon, and in the event of a dyssynergic pattern of pelvic floor muscles, the balloon would not be expelled due to increased muscle tension and shortening of the anorectal area. In this manner, the patient is trained to bring awareness to the anorectal area, and to respond with healthy patterns of defecation.

One study that compared biofeedback training to balloon-assisted training found that biofeedback was more effective in training patients for reduction of constipation. 65 patients, 49 women and 16 men, were included and were diagnosed with constipation and dyssynergia. In the balloon training (n = 31 patients were trained to expel the balloon with increased abdominal pressure and relaxed PFM, whereas in the biofeedback group (n = 34 the patients were trained to relax the pelvic floor muscles while increasing abdominal pressure. The good news is that while the biofeedback group reported higher levels of success in emptying, both groups reported positive effects of their training, with improved amount of stool passed, decreased maneuvers required to empty the bowels, and decreased time needed to defecate.

If you would like to learnabout sEMG for bowel dysfunction, sign up for the Pelvic Floor series 2A continuing education course. We are sold out for the rest of the year for PF2A, and the next opportunity to take the course will be next March in Madison, Wisconsin, or May of 2015 in Seattle. If you want to learn how to use balloon-assisted re-training techniques, you still have an opportunity this year to get into a course. Faculty member Lila Abatte has developed the Bowel Pathology, Function, Dysfunction, the Pelvic Floor course that still has seats left for the November, Torrance, California course.

Amy C. Sanderson - Featured Certified Pelvic Rehabilitation Practitioner

In our weekly feature section, Pelvic Rehab Report is proud to present this interview with newly certified practitioner Amy C. Sanderson, PT, OCS, PPRC.

Amy Sanderson

Describe your clinical practice.:

I am a co-owner of a private physical therapy practice in the Spokane, Washington area. We currently have 3 clinics and staff 14 providers overall. I have been an Orthopaedic Certified Specialist since 1996, and our clinic is primarily an orthopedic setting. We do, however, provide several specialties, including Pelvic Rehab, Vestibular Program, and Video Gait Analysis for athletes.

How did you get involved in the pelvic rehabilitation field?

I have been practicing since 1993 and began a Women’s Health program in 1994 at a previous place of employment. When I had interviewed for the position of a staff physical therapist for this clinic, I was asked if I would be interested in starting any new programs for the company. The manager had recommended that I develop a Women’s Health program. Truthfully, I had not heard of Women’s Health in the early 90’s, but I really wanted the job, so I said “absolutely!” I figured that I was a woman and I knew some things about health, so how hard could it be. Countless hours of continuing education and several years of marketing to the local physicians and community, we have now built our Pelvic Rehab program up to 3 physical therapists providing treatment to all of our clinics in the Spokane, Washington area.

What patient population do you find the most rewarding in treating and why?

I have enjoyed the patients who are experiencing sexual pain disorders for the past 15 years and have found this to be the most rewarding. Several times, I have been contacted after the birth of children to be told how grateful the couple has been to achieve such a life experience. Most recently, I received an email from a patient whom I had not seen in 3 years because she wanted to let me know that she and her husband were finally able to achieve intercourse after several years of counseling and my help with physical therapy. It is extremely gratifying to know that we can make a difference in peoples’ lives.

What motivated you to earn PRPC?

I have been practicing for greater than 20 years, including treating patients with all types of pelvic conditions, and after so many years, I wanted to challenge myself to see if truly what I was doing as a practitioner was effective, appropriate, and up to date. I decided that reviewing my education, seeking further education, and testing would be an effective way to do so. I felt that as I was preparing for this exam, I was able to realize that my treatment techniques are effective and appropriate. I am extremely grateful to the Herman & Wallace Pelvic Rehabilitation Institute for providing such great instructors to teach these skills.

Can Mindfulness Help Struggling Middle Schoolers?

mindfulness

In an encouraging study sure to grab a lot of attention, researchers studying middle schoolers and the effect of mindfulness on suicidal thoughts have positive findings. We all know that middle school is a very challenging time, with students feeling pressure socially, academically, hormonally, and that family stressors can also be involved in this time of significant growth and change. If we think back to our time in middle school, we may recall some very challenging emotions, and a difficulty in seeing past our school environment and into our potential future. What if mindfulness training could provide an outlet for positive thoughts and a way to more effectively manage emotions?

In this study, highlighted in the research spotlight of the National Center for Complementary and Alternative Medicine, 100 sixth graders were randomized into an Asian history class with daily mindfulness practice and into an African history class with a matched activity unrelated to mindfulness or self-care. The mindfulness instruction included breath awareness and breath counting, body sensation, thoughts, and emotions labeling, and body sweeps. Silent meditation increased from 3 minutes to 12 minutes. Over the study period of 6 weeks, students were assessed for development of suicidal thoughts or self-harm behaviors.

While the researchers conclude that more studies with larger groups need to be done to validate the findings, the reports of this study are very encouraging. Keeping in mind that there are no equipment needs and little or no risk with the applied intervention, perhaps more schools will look to trainable skills in mindfulness to teach young people self-management skills. Mindfulness and meditation continue to receive significant attention in the research literature, and rightly so, as patients, providers, and family members may benefit from simple techniques that can be practiced and applied in a variety of ways.

If you would like to learn more about how to practice and to teach skills in mindfulness, sign up early for our new continuing education course called Mindfulness-based Biopsychosocial Approach to Chronic Pain. Instructor Carolyn McManus has been studying, practicing, and teaching mindfulness to patients and providers for many years. This course can be taken by any health provider, so invite your colleagues to join you at the course! If you are not yet familiar with her work or her patient resources, you may find her guided meditation and relaxation CD's a terrific tool to share or utilize yourself. You can listen to samples of the work on her website by clicking here.

Is Place of Birthing a Choice?

pregnant

One thing I have decided after working with women during and after pregnancy is this: babies come when they want, and how they want to arrive. A mother's best laid birth plans will hopefully have enough flexibility to allow her to feel successful even if, and especially if, her plans have to change. A fundamental question that has been asked, from the standpoint of a mother's beliefs is, do women really feel they have a choice to deliver at home versus in a hospital?

Researchers in the UK asked this question of a diverse sample of 41 women who were interviewed. Despite the fact that in the UK, a woman can birth at home with a midwife (and this is covered by the National Health System) home births are unusual, accounting for only 3% of all births. And while it may seem exciting to read that in the US, the number of home births has risen by more than 50% over a decade, the actual numbers include that less than 2% of births occur at home according to the Centers for Disease Control (CDC) data.

Back to the concept of choice, when women were interviewed about where they planned to give birth, perceptions rather than fact ruled the day. The concept of which environments were "safe" versus "risky" were a common theme, with women having differing explanations of why a hospital might be more safe than the home environment, or vice versa. The authors describe the issue that, when healthy mothers with low-risk pregnancies give birth in hospital environments, medical interventions including surgical birth are more likely to place. Women who would choose a home birth reported beliefs such as not being able to have a 'natural' birth in a hospital, fear of contracting illness or disease, or of wanting to be at home surrounded by loves ones. Women also reported that at home, more control over the environment and increased ability to relax would be available.

On the other hand, women who wanted to give birth within a hospital associated the medical environment with safety and reassurance, and expressed fear of feeling guilty if events did not turn out well with a home birth. Unfortunately, some women reported feeling "unfit" to give birth and chose the hospital as a place where both mother and the baby would be more safe. This, I believe, is a very sad statement about the disempowerment that women feel in relation to their own ability to feel healthy and strong in their own body, and to trust that the birth experience can progress well in a multitude of environments. Women interviewed in the study cited marketing and propaganda as contributing to a sense of not being healthy or fit enough to manage the birth outside of a hospital.

The authors point out that "…beliefs and assumptions about birth risk are deeply ingrained…" and that fear of the risks of birthing at home, well-founded or not, remain prevalent. So what is our role? Perhaps to share that healthy women who have uncomplicated pregnancies have choices, and that we believe in their ability to make positive, strong choices that their bodies are fit to perform. There are many birthing centers that are designed with home comforts, and that offer a "middle ground" between a hospital center and a home environment. Home births can be attended by well-trained midwives or other practitioners who are experienced in knowing when and how to access more interventional approaches if needed. This post is not about whether a woman should give birth at home or in a hospital- that issue is hotly debated by many forums currently and by experts in the topic. What we as pelvic rehabilitation providers can continue to offer is coaching, encouragement, and education that is empowering to a woman, so that when she makes a decision (in conjunction with her chosen providers) about how she would like the birth of her child to be achieved, she feels "fit" to birth in the environment she chooses.

If you agree that we have a role in providing a platform from which we educate and empower women to trust their bodies and their choices about birthing, then you will L.O.V.E taking a course with Ginger Garner, a very empowered (and empowering) woman who is a relentless advocate of these issues. In New York, in November, you can take Ginger's continuing education course Yoga as Medicine for Pregnancy.

Stress & Bowel Dysfunction

digestive system

A recent article describing the impact of psychological factors on bowel dysfunction describes several mechanisms by which this may occur. Issues cited that may influence the bowels include psychological stress, which can lead to nausea, vomiting, abdominal pain, and changes in bowel patterns or habits. Stress can also affect the hypothalamus-pituitary-adrenal axis, or HPA axis. This axis is a major part of the neuroendocrine system that, in addition to controlling stress reactions, regulates many body functions such as digestion and immunity. During stress, cortico-releasing factor (CRF) can also be released, and act directly on the bowels or via the central nervous system. The authors point out that CRF can also affect the microbiota composition within the gut.

Corticotrophin-releasing factor can affect gut motility, permeability, and inflammation. The way in which motility is affected can vary, from increased movement of bowel contents to more sluggish movement, depending "…on the type of CRF family receptor expressed on the target organ." Gut permeability can also be affected by CRF, leading to bowel hypersensitivity and other issues such as nutritional absorption dysfunction. Stress-associated inflammation is also of concern, with markers of inflammation being found in patients who have irritable bowel syndrome and other conditions. Dysbiosis, or microbial imbalance, can be caused by stress, leading to changes in bowel motility , inflammation, and permeability, according to the referenced article. Diet-induced dysbiosis, discussed in this article, can lead to inappropriate inflammation and to cellular damage and autoimmunity, making a person vulnerable to chronic disease of the gastrointestinal tract. Such disease conditions may include ulcerative colitis, Chrohn's disease, celiac disease, and diabetes. Probiotics, prebiotics, and alterations in dietary intake are current therapeutic approaches, with further research needed to determine what types of interventions are most helpful for specific conditions.

Pelvic rehabilitation providers, especially those who are newer to the field, quickly discover that trying to treat pelvic dysfunction without knowledge of bowel health is like trying to treat low back pain while ignoring the pelvis: to truly ease symptoms both may need to be addressed. Patients often present with a combination of issues in the domains of bowel, bladder, sexual health and pain, and being able to address all with expertise aids in effectiveness of care. If you are interested in learning more about bowel dysfunction, faculty member Lila Abbate teaches her continuing education course "Bowel Pathology and Function" in California in early November. There is also an opportunity to learn about how to ameliorate stress and its potentially negative affects on bowel health by attending the Mindfulness-Based Biopsychological Approach to the Treatment of Chronic Pain taking place in Seattle in November.
