what happens if you hold your poop too long

Holding in poop once in a while is usually not dangerous, but doing it often or for too long can lead to constipation, pain, hemorrhoids, and, in extreme cases, serious bowel complications.

What Actually Happens Inside You

When you ignore the “time to go” signal, your rectum and colon hold stool longer than they’re designed to. Over time:

  • Water keeps being absorbed from the stool, making it drier and harder.
  • The colon stretches and pressure builds, causing cramps, bloating, and that heavy “full” feeling.
  • The nerves that signal “I need to poop” can get less sensitive if you ignore them often, so you may stop feeling the urge clearly.

One relatable example: someone who always waits until after work or school to go may gradually notice they’re going less often, with harder stools and more straining.

Short-Term Effects (Occasional Holding)

If you just have to wait a bit—like finishing a meeting or being stuck on a bus—your body usually copes fine.

Common short-term effects:

  • Temporary discomfort or cramping.
  • Feeling very full, gassy, or bloated.
  • A harder, larger stool when you finally go, which may be more painful to pass.
  • Mild anal irritation or small tears (anal fissures) from pushing out a big, hard stool.

For most healthy people, this kind of occasional delay is uncomfortable but not dangerous as long as it isn’t a daily habit.

When It Becomes a Problem

Holding your poop too often, or for very long periods, can cause more serious issues.

1. Constipation and pain

  • Chronic constipation: going less often, passing hard, dry stools, and straining.
  • Abdominal pain and bloating: stool builds up, stretching the colon.
  • Feeling like you can’t completely empty, even after you go.

2. Hemorrhoids and fissures

When you finally do go, you often have to push harder:

  • Hemorrhoids: swollen veins in the rectum or anus that can itch, hurt, or bleed.
  • Anal fissures: tiny tears in the anal lining that cause sharp pain and blood on the toilet paper.

3. Fecal impaction (severe blockage)

If stool stays in the colon too long, it can become so hard and stuck that you can’t push it out at all—this is called fecal impaction.

Possible signs:

  • No normal bowel movement for days plus strong urge but nothing (or almost nothing) comes out.
  • Leakage of runny stool around the hard mass (soiling), even though you feel “blocked.”
  • Strong abdominal pain, bloating, sometimes nausea or vomiting.

This is a medical emergency and often needs laxatives, enemas, or manual removal by a doctor.

4. Extreme complications (rare but serious)

In very severe, long-lasting cases:

  • “Megacolon”: the colon stretches massively, becomes weak and enlarged.
  • Ulcers and damage to the intestinal wall from constant stretching and pressure.
  • Intestinal perforation and sepsis: if the bowel wall tears, stool and bacteria can leak into the abdomen and bloodstream, which can be life-threatening.

These extreme outcomes are rare and usually occur in people with serious underlying issues, mental health conditions, or who avoid care for a long time.

Is It Bad If I Do It Sometimes?

For most people:

  • Occasionally holding it for an hour or two: usually fine, just uncomfortable.
  • Regularly ignoring the urge (daily, or for many hours at a time): not a good idea and raises risk of chronic constipation and other problems.

Doctors emphasize a “golden rule”: when your body says you need to poop, try to go within a reasonable time instead of repeatedly delaying it.

What You Should Do Instead

To keep your bowels happy:

  • Go when you feel the urge, as often as you reasonably can.
  • Aim for a routine: many people find they naturally go once a day or a few times a week, and regular timing helps.
  • Eat fiber: fruits, vegetables, whole grains, and beans help keep stool soft and bulky.
  • Drink enough water so your body doesn’t over-dry the stool.
  • Stay active: walking and exercise help the intestines move things along.

If you often feel like you have to hold it because of school, work, or anxiety about public bathrooms, it’s worth addressing those practical or psychological barriers too.

When To See a Doctor

You should get medical help if you:

  • Have not had a proper bowel movement for several days and feel very bloated or in pain.
  • Notice blood in your stool often, or severe pain when you pass stool.
  • Have unintentional weight loss, fever, or feel very unwell with bowel changes.
  • Regularly have to strain hard or feel like you can never fully empty.

These can signal fecal impaction or other conditions like inflammatory bowel disease, irritable bowel syndrome, or in rare cases, bowel cancer, so they should not be ignored.

“Quick Scoop” — TL;DR

  • Sometimes holding your poop: mostly just uncomfortable.
  • Doing it a lot or for very long: can cause constipation, pain, hemorrhoids, fissures, or even dangerous impaction and bowel problems.
  • Best practice: listen to your body and go when you need to, support it with fiber, water, and movement.

If you’re currently very uncomfortable, unable to poop, or in severe pain, contact a doctor or urgent care rather than waiting it out.
