Stool no longer exits through your anus after an ileostomy, because the small intestine has been rerouted to empty through a surgically created opening (stoma) on your abdomen. But “still pooping” is more complicated than it sounds, because many people with ileostomies do pass something from their backside, and many more feel the urge to. What happens down below depends largely on whether your rectum was left in place or removed during surgery, and the answer surprises a lot of new ostomates.
What Actually Comes Out of the Stoma
The output from an ileostomy is not the firm, formed stool you are used to. Your large intestine is the organ responsible for absorbing most of the water from digested food, so when the small intestine empties directly through a stoma instead, the output tends to be liquid to porridge-like in consistency. For most people, the stoma produces waste fairly continuously throughout the day rather than in discrete “bowel movements,” though output is usually heaviest after meals.
Because so much fluid bypasses the colon, dehydration is a genuine concern. A high-output stoma, defined as producing more than about 1.5 to 2 liters a day, occurs in up to roughly a third of small bowel stomas and can cause depletion of water, sodium, and magnesium.1Frontline Gastroenterology. How to manage a high-output stoma The most common triggers for an early high-output stoma include having less small bowel remaining, intra-abdominal infection, or obstruction. In one treatment series, about seven in ten patients with high output were able to stop intravenous fluid support once they restricted hypotonic drinks, used an oral glucose-saline solution, and took anti-diarrheal medication.2PubMed. Causes and management of a high-output stoma That is encouraging, but it underscores why staying on top of hydration and electrolyte intake matters so much with an ileostomy.
When You Still Pass Something From Your Backside
If your rectum was left in place during surgery, which is the case with loop ileostomies and many end ileostomies, the lining of the rectum continues to produce mucus. This is normal: the rectal lining secretes mucus regardless of whether stool is passing through it. The result is that you may occasionally feel the need to sit on the toilet and pass a glob of mucus, sometimes tinged with a small amount of old stool or blood. Some people describe it as a slimy, jelly-like discharge; others barely notice it.
This happens frequently enough that most people who retain a rectal stump deal with it at some point. A multi-center study of patients with stomas found that roughly two-thirds needed at least one intervention for persistent rectal mucus discharge, including enemas, irrigation, or, in a smaller number of cases, surgical removal of the rectal stump.3PubMed Central. Benign functional anorectal conditions: a multi-centre analysis of rectal stump symptomatology in patients undergoing stoma formation The discharge itself is not dangerous, but it can be messy, uncomfortable, and alarming if nobody warned you it would happen. If you have a loop ileostomy, the good news is that interventions for mucus discharge tend to work well: the same study found that about four in five patients with a loop ileostomy saw improvement after treatment.
Diversion Proctitis and the “Forgotten Rectum”
When the fecal stream is diverted away from the rectum for months or years, the rectal lining can become inflamed. This condition, called diversion proctitis, happens because the cells lining the rectum depend on nutrients produced by gut bacteria fermenting food. Without stool passing through, those bacteria lose their food supply, and a key fuel source for rectal cells, short-chain fatty acids, drops off dramatically.4PubMed Central. Diversion proctocolitis and the problem of the forgotten rectum in inflammatory bowel diseases: A systematic review Think of it like a muscle that wastes away from disuse, except it is the lining of your rectum slowly losing its nutritional support.
Diversion proctitis can cause bleeding from the rectum, increased mucus discharge, cramping, and a feeling of pressure. In people who already have inflammatory bowel disease, the picture gets murkier because the inflammation from diversion can overlap with disease-related flare-ups, making it harder for doctors to tell what is causing what.5Journal of Crohn’s and Colitis. The Impact of Rectal Stump Inflammation After Subtotal Colectomy on Pouch Outcomes in Ulcerative Colitis Patients
The treatment is elegantly logical: put back what is missing. Enemas containing short-chain fatty acids, given once or twice daily, have been shown to resolve symptoms and visible inflammation within about four to six weeks. One landmark study found that remission could be maintained for over a year with ongoing treatments spaced out to just a couple of times per week, while switching to plain saline enemas or stopping treatment led to rapid relapse.6PubMed. Treatment of diversion colitis with short-chain-fatty acid irrigation Other options include steroid enemas and sucralfate enemas, which were among the approaches used in the multi-center study mentioned earlier.3PubMed Central.

Why You Still Feel the Urge to Go
One of the strangest experiences after ostomy surgery is feeling like you need to have a bowel movement the old-fashioned way, even when there is nothing in your rectum. If the rectum is still present, the urge can be real: mucus accumulates, and the rectal nerves detect it and send the familiar signal to your brain. But the sensation can also happen after the rectum has been completely removed, a phenomenon known as phantom rectum syndrome.
Phantom rectum works on the same principle as phantom limb pain in amputees. The nerves that used to carry signals from the rectum still exist and still fire. In a study of patients who had their rectums surgically removed for rectal cancer, 96% experienced phantom rectum sensations at some point during the first eight months after surgery. Nonpainful sensations, such as a vague fullness or the urge to defecate, were the most common and often cropped up when the stoma was actively emptying. Painful sensations, described as pins and needles, stinging, or burning, affected a smaller group and tended to flare up while sitting.7PubMed. Perceptions of phantom rectum syndrome and health-related quality of life in patients following abdominoperineal resection for rectal cancer
The practical takeaway: if you feel the urge to poop after ileostomy surgery, you are not imagining things, and it does not mean something went wrong. If your rectum is still intact, sitting on the toilet and allowing mucus to pass is perfectly reasonable. If the rectum was removed, the sensation will usually diminish over time but can persist intermittently for months or even years.
When the Rectum Is Gone Entirely
For some conditions, particularly severe perianal Crohn’s disease or certain cancers, surgeons remove the entire rectum and colon in a procedure called total proctocolectomy with end ileostomy. In this situation, there is no rectal stump to produce mucus and no pathway for anything to exit through the anus, which is typically surgically closed. You genuinely cannot poop from below, and the stoma becomes your permanent route for waste.
This does not mean the story ends cleanly. Crohn’s disease, for instance, can recur in the remaining small bowel even after the colon and rectum are gone. The estimated clinical recurrence rate reaches about 39% over 20 years, and roughly one in four patients needs reoperation for small bowel recurrence within 15 years. The main risk factor for recurrence is having active small bowel disease at the time of the original surgery.8PubMed Central. Long-Term Complications of Proctectomy for Refractory Perianal Crohn’s Disease: A Narrative Review These recurrences can affect stoma output, nutrition, and the risk of needing further resections. Having a permanent ileostomy does not mean the underlying disease is cured; it means the most damaged part of the gut has been removed.
Ileostomy Reversal and Getting Back to “Normal”
Many ileostomies are temporary. Loop ileostomies, in particular, are often created to protect a surgical join further downstream while it heals. Once healing is confirmed, the stoma is reversed and the intestine reconnected. A study of rectal cancer patients found that about 79% had their ileostomies reversed, at a median of roughly five and a half months after the initial surgery.9PubMed. Assessing the pathway and timing for ileostomy reversal in rectal cancer: A retrospective cohort study That leaves about one in five patients who, for various medical reasons, never get reversed.
After reversal, bowel function does not snap back to normal overnight. The first stool typically arrives about two to three days after surgery, and early bowel habits are often irregular: frequent, loose stools, urgency, and sometimes incontinence. The intestine has been diverted for months, and both the rectal stump (which has been idle) and the small bowel need time to readjust. Research on stimulating the unused downstream bowel before reversal, by instilling the patient’s own ileostomy effluent into the defunctionalized loop, has shown promise in speeding recovery. In one trial, patients whose distal bowel was stimulated this way passed their first stool more than a day sooner on average and left the hospital roughly a day and a half earlier than controls.10Tropical Gastroenterology. Effect of Distal Loop Stimulation with Ileostomy Effluent on Return of Bowel Function Post Ileostomy Reversal in Emergency Laparotomy Patients
Bowel function after reversal improves gradually over weeks and months. Some people report near-normal habits within a few months; others deal with increased frequency or loose stools for a year or more. If your rectum was preserved and you eventually get an ileal pouch-anal anastomosis (J-pouch), functional outcomes such as stool frequency, continence, and skin irritation are typically assessed at least a year after the pouch is connected, because it takes that long for the pouch to stretch and the body to adjust.11PubMed. Anal and ileal pouch manometric measurements before ileostomy closure are related to functional outcome after ileal pouch-anal anastomosis
How the Small Bowel Adapts Over Time
One underappreciated aspect of living with an ileostomy, or with a shortened gut after surgical reconnection, is that the remaining small intestine physically changes to compensate. The inner lining remodels: the tiny finger-like projections (villi) that absorb nutrients grow taller, and the pits at their base deepen, increasing the surface area available for absorbing water and nutrients per unit length of bowel.12PubMed Central. The Pathogenesis of Resection-Associated Intestinal Adaptation This adaptation has been demonstrated in animal models, where increased villus height was observed after both ileostomy and ileoproctostomy, and researchers believe it contributes meaningfully to improved water and salt absorption over time.13PubMed. Small-bowel adaptation after colectomy in rats
This is why ileostomy output often becomes thicker and less voluminous over the months following surgery. The body is not simply accepting the loss of the colon; it is actively compensating. The adaptation is not a complete replacement for colonic function, so output will always be looser than normal stool, but the trajectory is usually toward less liquid and more manageable volume as the weeks pass.
The Emotional Side of Changed Bowel Function
Questions about whether you can still poop are often proxies for a deeper set of concerns: Will my body still work in a way that feels recognizable? Will other people notice? Can I live normally? These are not trivial worries. Research consistently identifies poor body image, depression, sexual difficulties, and challenges with psychosocial adaptation as common among people living with stomas.14PubMed Central. Overview of psychosocial problems in individuals with stoma: A review of literature
Mucus discharge from the rectum, phantom urges, unexpected gas from the stoma at inconvenient moments, and the learning curve of bag management all contribute to a sense of lost control. Many people find that connecting with an ostomy nurse specialist early and often makes a significant difference, not just for practical bag-fitting advice but for normalizing the experience. Support groups, whether in-person or online, are another resource that ostomates frequently credit with helping them adjust. The concerns are real, common, and not something you need to navigate alone.
Practical Tips for Managing Rectal Discharge
If you have a retained rectum and are dealing with mucus discharge, a few strategies can help. Sitting on the toilet periodically, even without stool to pass, lets accumulated mucus drain. Some people find that gentle bearing down helps, while others prefer to wait for the urge. Wearing a small pad can catch unexpected leakage between bathroom visits.
If the discharge is heavy, bloody, or accompanied by cramping, talk to your surgical team. These symptoms may indicate diversion proctitis, which is treatable with the enema approaches described earlier. The distinction between benign mucus production and active inflammation matters, because diversion proctitis left untreated can worsen and potentially complicate future reversal surgery. Your surgeon or gastroenterologist can evaluate the rectal stump with a brief scope exam and recommend the right type of enema if needed.
For people with an end colostomy rather than a loop ileostomy, interventions for mucus discharge tend to be less successful, with only about one in five seeing improvement in one study, compared to nearly four in five with a loop ileostomy.3PubMed Central. Benign functional anorectal conditions: a multi-centre analysis of rectal stump symptomatology in patients undergoing stoma formation This difference likely reflects the anatomy: loop stomas maintain some continuity with the downstream bowel, so treatments can reach the target tissue more easily. If you have an end stoma with persistent, bothersome discharge that does not respond to conservative measures, completion proctectomy, removing the remaining rectum, may be discussed as a last resort.
When To Be Concerned About What Comes Out
Most rectal discharge with a retained stump is harmless mucus. But certain signs warrant prompt medical attention. Fresh blood mixed with the mucus in significant amounts could indicate worsening diversion proctitis, a rectal ulcer, or, in rare cases, a new problem in the rectal stump. Foul-smelling discharge accompanied by fever may suggest an infection or an abscess near the stump or surgical site. And if you had your ileostomy for cancer, any new symptoms from the rectum should be reported so your team can rule out local recurrence.
On the stoma side, output that suddenly becomes watery and very high volume can signal a bowel obstruction just upstream of the stoma, an infection like gastroenteritis, or a medication side effect. A sudden drop in output, on the other hand, may mean the stoma is partially blocked. Both extremes deserve a call to your care team. Learning what your personal “normal” looks like in terms of stoma output color, consistency, and volume is one of the most useful things you can do in the first few months, because it gives you a baseline for recognizing when something is off.
