Anismus (Dyssynergic defecation)

“Finding relief from the struggle — restoring natural bowel function and easing the stress of every bathroom visit.”

What is Anismus (Dyssynergic defecation)?

Anismus, also called dyssynergic defecation, is a pelvic floor coordination disorder where the muscles around the rectum tighten instead of relaxing during a bowel movement. This makes it difficult for stool to pass, even when the urge to go is strong. Over time, this can lead to straining, incomplete emptying, and discomfort, impacting daily routines and quality of life. The condition can develop due to pelvic floor muscle tension, learned patterns from past pain, or neurological signals that misfire during the process of elimination.

Common Symptoms

How Does It Feel?

  • Straining during bowel movements despite soft stool
  • Feeling of incomplete evacuation
  • Needing to change position or use manual techniques to pass stool
  • Abdominal bloating or discomfort after attempting to go
  • Rectal pain or pressure during or after a bowel movement
  • Frequent, unsuccessful urges to have a bowel movement

HOPE

What Causes It?

Anismus often results from a miscommunication between the brain and pelvic floor muscles, leading them to contract instead of relax during defecation. This can be triggered by a history of painful bowel movements, chronic constipation, or anal fissures that cause protective tightening over time. Other contributors may include pelvic floor muscle overactivity, scar tissue from surgery or childbirth, nerve dysfunction, or prolonged straining habits. Stress, anxiety, and changes in bowel routines can perpetuate the cycle, making symptoms more persistent.

How We Identify the Root Cause

Our evaluation begins with a detailed discussion of your medical history, bowel habits, and symptom patterns. We perform a gentle pelvic floor muscle assessment to evaluate muscle coordination, strength, and relaxation ability. Depending on your needs, we may collaborate with your physician for additional tests such as anorectal manometry or defecography to visualize muscle function during a bowel movement. This comprehensive approach ensures we address not only the symptoms but also the underlying movement patterns contributing to the problem.
