As many as 50 percent of people with chronic constipation have pelvic floor dysfunction (PFD) — impaired relaxation and coordination of pelvic floor and abdominal muscles during evacuation. Straining, hard or thin stools, and a feeling of incomplete elimination are common signs and symptoms. But because slow transit constipation and functional constipation can overlap with PFD, some patients may also present with other signs and symptoms, such as a long time between bowel movements and abdominal pain.
Mechanistically, the causes of pelvic floor dysfunction are two-fold: widening of the pelvic floor hiatus and descent of pelvic floor below the pubococcygeal line, with specific organ prolapse graded relative to the hiatus. Associations include obesity, menopause, pregnancy and childbirth. Some women may be more likely to developing pelvic floor dysfunction because of an inherited deficiency in their collagen type. Some women may have congenitally weak connective tissue and fascia and are therefore at risk of stress urinary incontinence and pelvic organ prolapse.
Surface electrodes (self-adhesive pads placed on your skin) can test your pelvic muscle control. This might be an option if you don’t want an internal exam. The electrodes are placed on the perineum (the area between the vagina and rectum in women, and between the testicles and rectum in men) or on the sacrum (the triangular bone at the base of your spine). This test is not painful.
Pelvic floor dysfunction is an umbrella term for a variety of disorders that occur when pelvic floor muscles and ligaments are impaired. Although this condition predominantly affects females, up to 16% of males suffer as well. Symptoms include pelvic pain, pressure, pain during sex, incontinence, incomplete emptying of feces, and visible organ protrusion. Tissues surrounding the pelvic organs may have increased or decreased sensitivity or irritation resulting in pelvic pain. Underlying causes of pelvic pain are often difficult to determine. The condition affects up to 50% of women who have given birth.
Pelvic floor dysfunction (PFD) refers to a broad constellation of symptoms and anatomic changes related to abnormal function of the pelvic floor musculature. The disordered function corresponds to either increase activity (hypertonicity) or diminished activity (hypotonicity) or inappropriate coordination of the pelvic floor muscles. Alterations regarding the support of pelvic organs are included in the discussion of PFD and are known as Pelvic Organ Prolapse (POP). The clinical aspects of PFD can be urologic, gynecologic, or colorectal and are often interrelated. Another way to compartmentalize the concerns are anterior- urethra/bladder, middle- vagina/uterus and posterior- anus/rectum.
Home exercise and therapy is also a mainstay of PFD rehabilitation. Because the goal of PFD therapy is to learn to control and, especially, relax the pelvic floor, therapists will teach you techniques for use at home to build on the therapies they do in their offices. This usually begins with general relaxation, stretching the leg and back muscles, maintaining good posture, and visualization—part of learning to sense your pelvic floor muscles and to relax them.
A defecating proctogram is a test where you’re given an enema of a thick liquid that can be seen with an X-ray. Your provider will use a special video X-ray to record the movement of your muscles as you attempt to push the liquid out of the rectum. This will help to show how well you are able to pass a bowel movement or any other causes for pelvic floor dysfunction. This test is not painful.
The pelvic floor muscles support various pelvic organs, including the bladder, prostate, rectum, and female reproductive organs. The muscles themselves are also involved in the functioning of the urinary and anal sphincters. When they are functioning normally, you are able to control your bowel and bladder movements by contracting and relaxing these muscles.
If you think of the pelvis as being the home to organs like the bladder, uterus (or prostate in men) and rectum, the pelvic floor muscles are the home’s foundation. These muscles act as the support structure keeping everything in place within your body. Your pelvic floor muscles add support to several of your organs by wrapping around your pelvic bone. Some of these muscles add more stability by forming a sling around the rectum.
Currently there is no surefire way to distinguish PFD from IC, and oftentimes patients have both conditions. Some healthcare providers examine pelvic floor muscles externally and internally to gauge their tightness (tightness indicates PFD). Other IC and PFD experts, like ICA Medical Advisory Board member, Robert Moldwin, MD, perform a lidocaine challenge. By instilling lidocaine into the bladder, Dr. Moldwin determines whether your pain is coming from your bladder, which would indicate IC.
If you have problems with constipation due to hard bowel movements or abdominal bloating and gas pain, then you should consult with your doctor and watch your diet closely. It’s important to drink plenty of water daily (>8 glasses) and eat a healthy diet. Foods that are high in fiber, or fiber supplements, may worsen your bloating symptoms and gas pains. These foods should be avoided if your symptoms get worse.
Increases bladder and bowel control. The pelvic floor muscles are directly responsible for controlling urine and bowel movements. If these muscles are weak, you’re more likely to experience constipation, urinary incontinence, struggle to control flatulence, or experience urine leakage from forceful activities like when sneezing, coughing, or laughing (called “stress incontinence”). Strengthening your pelvic floor can improve your bowel and bladder control.
