At a glance
The feeling that something is stuck in the rectum is one of the most commonly searched colorectal symptoms. It is described in many ways: a lump, a fullness, a pressure, a sense of something sitting there that will not pass. Some people feel it constantly. Others notice it mainly during or after bowel movements.
This sensation is very common, usually not dangerous, and has several possible causes. Understanding what might be behind it can help you have a more useful conversation with your doctor.
Common causes
Hemorrhoids
Internal hemorrhoids are one of the most frequent causes of this sensation. When internal hemorrhoids enlarge, they can occupy space in the rectal canal and create a feeling of fullness or a lump. People commonly describe:
- A sense that something is sitting just inside the opening
- The feeling worsening during or after bowel movements
- A lump that seems to come down with straining and either goes back on its own or needs to be gently pushed back
- The sensation being worse during flare-ups and better at other times
External hemorrhoids or thrombosed hemorrhoids can also produce a sense of something being there — felt as a firm lump at or near the anal opening.
Rectal prolapse
Rectal prolapse occurs when a portion of the rectal lining or rectal wall slides downward through the anal canal. People describe:
- A distinct sensation of something descending during bowel movements
- Tissue that may protrude from the anus during straining
- A feeling of heaviness or dragging in the rectum
- The sensation that the tissue comes down and may or may not return to its normal position
Prolapse ranges from mild (internal mucosal prolapse that cannot be seen externally) to more significant (full-thickness prolapse that protrudes visibly). Even mild prolapse can produce a strong sense of something being stuck.
Pelvic floor dysfunction
The pelvic floor muscles play a critical role in bowel function. When these muscles are too tight (hypertonic) or do not coordinate properly, they can create the sensation of incomplete evacuation or a blockage:
- Muscles that do not relax properly during a bowel movement, creating resistance
- The feeling of needing to pass more stool even when the rectum is empty
- A sensation of pressure or fullness in the rectal area
- Symptoms that worsen with stress and tension
Pelvic floor dysfunction is frequently underdiagnosed. The symptoms overlap significantly with hemorrhoids and other conditions, and many people go through multiple evaluations before it is identified.
Rectocele
A rectocele is a bulging of the rectal wall, most commonly into the vaginal wall. It is more prevalent in people who have had vaginal deliveries or pelvic surgery. People describe:
- The sensation of stool getting trapped in a pocket
- Difficulty fully emptying during bowel movements
- Needing to apply pressure to the vaginal area to complete evacuation
- A feeling of fullness or bulging that is worse after straining
Retained stool
Sometimes the sensation is exactly what it seems — there is stool that has not fully passed. This is particularly common with:
- Constipation — hard, dry stool that is difficult to move
- Large-volume stools that do not pass completely in one sitting
- Slow transit through the lower bowel
Other less common causes
- Rectal polyps — growths on the rectal lining that are usually found during examination
- Rectal intussusception — a folding of the rectal wall that can create an internal obstruction
- Perianal skin tags — excess skin near the anus that can feel like a lump
What people commonly describe
The language people use to describe this sensation is remarkably consistent:
- “It feels like something is stuck in there and will not come out”
- “Like there is a ball or lump sitting just inside”
- “The feeling that I have not finished, even though I have”
- “Pressure, like something is pressing down from inside”
- “A heaviness in the rectal area that does not go away”
People often describe the sensation as being at its worst after bowel movements, when they expect to feel empty but instead feel full. The frustration of repeated trips to the bathroom — trying to fully evacuate — is a common theme.
What tends to help
- Addressing underlying constipation — fibre, hydration, and if needed, stool softeners to ensure stools are soft and easy to pass
- Not forcing it — if the bowel movement feels complete but the sensation remains, it may be the sensation itself rather than retained stool. Spending excessive time straining can worsen hemorrhoids and pelvic floor tension.
- Positioning — a footstool to elevate the feet can help straighten the anorectal angle and improve evacuation
- Pelvic floor relaxation — for people whose symptoms are related to muscle tension, learning to relax the pelvic floor during bowel movements can reduce the sensation
- Responding to urges promptly — going when the body signals readiness rather than delaying
- Warm sitz baths — can help relax the muscles and reduce hemorrhoid swelling
- Limiting toilet time — if nothing more is coming, getting up and returning later rather than prolonged straining
What makes the sensation worse
- Straining or bearing down forcefully during bowel movements
- Spending extended time sitting on the toilet
- Constipation and hard stools
- Anxiety about the sensation — which can increase pelvic floor tension
- Delaying bowel movements, leading to larger, harder stools
- Ignoring the symptom and hoping it resolves without investigation
Talking to your doctor
This is a symptom that benefits from clinical evaluation. A physical examination can quickly narrow down the likely cause in most cases. Before your appointment, it helps to note:
- When you first noticed the sensation
- Whether it is constant or comes and goes
- Whether it is worse during or after bowel movements
- Whether you can feel or see any tissue protruding
- Your typical stool consistency and frequency
- Whether you have bleeding and what it looks like
- Whether the sensation is getting better, staying the same, or getting worse
- What you have already tried
Many people feel embarrassed raising this symptom. It is worth knowing that doctors encounter this complaint regularly, and being specific about what you feel helps them identify the cause efficiently.
When to contact your doctor
- Heavy bleeding that does not stop
- Severe or worsening pain
- Actual foreign body concern
- A prolapse that will not reduce — tissue that cannot be pushed back in
- Sudden inability to pass stool or gas
- Unexplained weight loss alongside bowel changes
- Changes in bowel habits lasting more than two weeks
- The sensation is significantly affecting your quality of life
If you cannot pass stool or gas at all, or if you have significant abdominal pain and bloating alongside this sensation, seek emergency care. These could indicate a bowel obstruction, which requires immediate medical attention.
For most people, this sensation is not dangerous — but it is worth investigating. The cause is usually identifiable, and effective management is available for all of the common causes described above.
