Feeling of Incomplete Emptying (Tenesmus)

A persistent sense that your bowel movement isn’t finished — even right after using the bathroom — is a genuinely uncomfortable symptom with a range of possible causes, from prolapsing hemorrhoids to several conditions covered elsewhere on this site.

Key takeaways

This feeling, called tenesmus clinically, can result from hemorrhoids, but also from proctitis, IBD, or solitary rectal ulcer syndrome, among other causes.
Persistent tenesmus that doesn’t resolve with typical hemorrhoid self-care is worth mentioning specifically to a doctor, since it points toward several other possibilities.
This symptom alongside straining is part of the pattern associated with solitary rectal ulcer syndrome and pelvic floor dysfunction specifically.

What causes this sensation

Tenesmus can result from actual physical obstruction or irritation low in the rectum (which prompts a genuine, if inaccurate, urge signal), or from inflammation anywhere in the rectal lining that mimics the sensation of needing to go. Several distinct conditions can produce this:

Prolapsing internal hemorrhoids — displaced tissue can create a persistent sensation of fullness or the need to go
Proctitis — inflammation of the rectal lining from various causes (see Proctitis: causes and symptoms)
Inflammatory bowel disease — particularly ulcerative colitis affecting the rectum (see Ulcerative colitis and rectal bleeding)
Solitary rectal ulcer syndrome — a less common condition where this symptom, alongside straining, is a defining feature (see Solitary rectal ulcer syndrome)
Pelvic floor dysfunction — uncoordinated pelvic floor muscles during attempted bowel movements can produce this sensation even without a specific structural cause (see Kegel and pelvic floor exercises)

Why this symptom is worth taking seriously if persistent

Unlike some hemorrhoid symptoms that clearly correlate with a bowel movement and then resolve, persistent tenesmus — feeling this way much of the time, not just briefly after going — is a pattern that overlaps significantly with several conditions beyond simple hemorrhoids, making it worth a direct conversation with a doctor rather than continued self-management if it doesn’t improve with standard hemorrhoid care.

What to describe to your doctor

How often you feel this — after every bowel movement, or more constantly throughout the day
Whether it’s accompanied by straining, bleeding, or diarrhea
Whether it’s new or has been present for an extended period
Any association with a known hemorrhoid diagnosis, and whether standard treatment for that has helped this specific symptom

When to see a doctor

Persistent tenesmus that doesn’t improve with standard hemorrhoid self-care
This symptom alongside diarrhea, bleeding, or significant straining
Any of the broader red flags for bowel habit changes
