This question has often been wondered about, but very few of us actually ever decide to research it. As crazy as it might sound, it is actually possible to throw up poop.

Vomiting poop in the mouth is indeed a horrid thought, but it needs to be addressed. 

Today, we’re going to look at throwing up feces, why it can happen, and what to do about it. 

What? Can You Throw Up Poop?

Feculent vomiting as described in medical literature is a condition caused by an intestinal blockage. 

Research has suggested that the uncommon condition of vomiting stool was probably due to intestinal blockage or an abnormal intestinal contraction of the muscles.

Mechanical Intestinal Obstruction 

This type of intestinal obstruction can be caused by a variety of underlying conditions. Some of these include: 

Crohn’s Disease

Crohn’s disease is a condition in which people develop abdominal pain, bloating, diarrhea or blood in the stool.  With longstanding uncontrolled inflammation, stricturing or narrowing of the intestine is possible, which can lead to a blockage.

Colon Cancer 

Cancer of the colon can lead to unnatural bowel movements and gastrointestinal complications.

Tumors can lead to obstruction of the colon, and eventually the stool backs up leading to feculent vomiting. 


Volvulus is the twisting of the intestine which can cause blockages and obstruction. This typically occurs in older patients with “floppy” intestines, but can also occur in younger people. 

Adhesions or Scar Tissue 

This might be caused by a previous surgery or abdominal injury. Loops of bowel can get hung up on the adhesions which can cause partial or complete bowel obstructions.   


Far more common in children, this condition occurs when the intestine telescopes into itself, which can lead to a blockage. 

Ileus or Paralytic Obstruction 

This is the second identified potential cause of blockage that could lead to people throwing up stool. Several factors can contribute to the development of an ileus:


Infections can cause a heap of internal problems. Gastrointestinal infections typically cause diarrhea, but in some cases, the bowel can slow down.  

An ileus can also develop in people who have other infections, like pneumonia or urinary tract infections.


People recovering from surgery commonly develop this condition, in which the bowels “slow down” or “go to sleep.”  

This is usually exacerbated by immobility and blood electrolyte abnormalities.


Medications can often disagree with your stomach and bowel’s natural movements.

As such, you may have reactions, blockages or other responses to your medication such as constipation. 

Symptoms Of Feculent Vomiting 

We’d have to go by what others have said due to limited research and achievable tests. Third party accounts have said that they’ve experienced: 

  • Nausea and vomiting of stool
  • Foul smelling breath
  • Extreme pain in the abdomen 
  • Inability to pass gas or stool 
  • Abdominal swelling/bloating 
  • Constipation 
  • Unexplained loss of appetite 

I’m Experiencing Some Of These Symptoms – What Should I Do? 

Undoubtedly you should see your doctor immediately. Some of the symptoms raised can be indicators of serious medical conditions and can be dangerous on their own anyway. 

Are There Treatments? Cure?

The treatment of feculent vomiting depends on the cause.  In cases of a mechanical blockage from an intestinal stricture, colon cancer or adhesions, surgery may be required.

In cases of a paralytic ileus, mobility, correcting electrolyte abnormalities, discontinuing any medications that may be contributing to it, and sometimes decompressing the stomach with a tube inserted through the nose can help resolve the issue.

Hospitalization will likely be required if you’re experiencing an intestinal blockage.

Treatments For Underlying Conditions 


Changing your diet and exercise regime is a great start to treating constipation.

Reducing caffeine and alcohol intake is one fantastic change to assist here. Adding fibrous foods to your daily diet will also help with constipation.

Medications you can buy at the drug store can help like fiber supplements, miralax, or milk of magnesia. Failing this, your doctor might be able to prescribe other medications. 

Abdominal Cramps 

Abdominal cramps can be treated but it is usually easier to treat if you understand why you’re experiencing these pains.

For example, if it is due to food poisoning – it is unlikely you’ll be able to keep down any medications. Therefore, you’re better off sticking to water and dry toast until you’re well enough to see a doctor. 

However, if the cramps are caused by trapped gas or foods that you have eaten – over the counter medications like Gas Ex can help with the pain and try to give you some relief and normality back. Regular exercise can also help to eliminate trapped gas – even a quick after dinner walk.

Loss Of Appetite And Weight Loss 

Unexplainable weight loss or loss of appetite would certainly require medical intervention. However, there are some things that could help.

Eating smaller, more frequent meals can help reduce the feeling of fullness and allow more calories to be consumed to help reduce weight loss.

Your doctor may also recommend nutritional supplements like Boost or Ensure to help achieve caloric and nutritional goals.

What To Remember 

Vomiting stool is rare and can result from a variety of conditions, most often involving a mechanical bowel blockage or significant motility issue.

If you are concerned you could have a bowel obstruction, see your doctor immediately!
