Many parts of your body make mucus, including your intestines. It lines your digestive tract, creating a protective layer against bacteria. It also helps waste pass smoothly through your colon. Some of it can stick to poop as it leaves your body.
Is Mucus in My Poop Normal?
It can be. If you feel fine and there's only a little mucus, you probably don't need to worry. But it may signal a problem when:
- There's a lot of mucus.
- You notice it often.
- You also see blood.
- You have diarrhea.
- You have belly pain.
If you have any of these symptoms, call your doctor.
Many types of digestive problems can make more mucus show up in your poop. Some are serious and long-lasting. Others, like food poisoning, can clear up quickly. A few examples:
Irritable bowel syndrome (IBS). The main symptoms may be constipation (IBS-C), diarrhea (IBS-D), or alternating diarrhea and constipation (IBS-A). It’s typical to see mucus in your poop if you have this condition.
Ulcerative colitis. This type of inflammatory bowel disease (IBD) causes sores in the intestines. They can bleed and make pus and mucus, which you might see when you go to the bathroom. It also often causes diarrhea, belly pain, and cramping.
C. difficile (c. diff ). Infection with this type of bacteria can cause severe, even life-threatening diarrhea. It smells very bad and often has mucus.
Other infections. An infection with other bacteria or parasites can also cause the problem. Dysentery is one example.
Getting a Diagnosis
If your doctor thinks the mucus is related to a health problem, you may get a stool test. It's also called a stool culture or stool sample, and it can show whether you have an infection.
You don't need any special prep for this test. You simply put a small sample of your poop in a container that your doctor gives you.
Your doctor may also order a few other tests, too. The ones you get will depend on the other symptoms you’re having. Some examples of additional testing include:
- Ultrasound. This scan uses sound waves to make pictures of your organs inside your belly.
- A contrast enema. Your doctor puts a thin tube in your bottom to fill your colon with liquid containing iodine or barium. Those substances help your intestines show up clearly on an X-ray image.
- Blood tests
- Colonoscopy. Your doctor uses a thin, flexible tube with a camera to look inside your colon.
- MRI. This scan that uses powerful magnets and radio waves to make a picture of your insides.
The treatment you get for mucus in your poop depends on the problem that’s causing it. Some conditions will need medicine and others won't. For example, with mild food poisoning, you may only need to drink more fluids. On the other hand, you need antibiotics to treat infection with C. diff.
Once you have a diagnosis, you and your doctor should talk about the best treatment for that condition.
