If you notice blood clots in your stool, it’s important to reach out to your healthcare provider as soon as possible.

Because there are many possible causes for seeing blood in your stool, a consultation with your provider is essential to getting the right care and treatment. 

If you’re otherwise healthy, mucus alone in your stool may not be cause for concern.

But if mucus and blood are found in your stool, or if you’re experiencing other symptoms, it’s important to speak to a provider.

In this article, we’ll cover the possible causes of blood and mucus in your stool and which treatment options your provider may recommend.

Keep in mind that this guide is not meant to replace a one-on-one consultation with your provider. If you notice blood clots and mucus in your stool, it’s important to seek medical attention immediately.

Blood Clots in Stool

Blood clots in stool are a sign of bleeding somewhere in your gastrointestinal (GI) tract.

Bright red blood in your stool usually signals bleeding from your lower colon or rectum, while dark red blood can indicate bleeding higher in the colon or small bowel.

Causes of Blood Clots in Stool

There are several possible causes of blood clots in your stool.

When you notice blood clots in your stool, it’s very important to speak with your healthcare provider as soon as possible to determine the right cause and course of treatment.

Peptic ulcer disease

Peptic ulcers, also known as stomach ulcers, gastric ulcers, and duodenal ulcers, are sores in the lining of your stomach or duodenum which can occur as a result of infection, long-term use of nonsteroidal anti-inflammatory medicines (NSAIDs), or when digestive acids damage the stomach or intestine walls.

The primary symptom of peptic ulcers is a burning stomach pain which usually happens between meals or during the night.

Antacids can help provide temporary relief, but in many cases, the pain comes and goes for several days or weeks.

Unfortunately, peptic ulcers will worsen if they’re not treated, so it’s important to speak to your provider if you’re experiencing symptoms.


Diverticulosis is a condition in which small bulges or pockets (known as “diverticula”) form in the colon.

For many people, these diverticula don’t cause any symptoms.

However, if a small blood vessel within these pouches bursts, it leads to diverticular bleeding, which may be severe and life-threatening. In some cases, surgery may be required to stop the bleeding. 

Infectious colitis

Infectious colitis is an infection of the colon caused by bacteria, viruses, or parasites.

The inflammation can cause bloody and/or mucousy diarrhea.

Other possible symptoms include: 

Pathogens that can cause infectious colitis include:

  • Salmonella
  • Shigella
  • E. coli
  • Norovirus
  • Rotavirus
  • Adenovirus
  • Some sexually transmitted infections (STIs)

Treatment will vary depending on the type of infection you have.

An estimated 47% of infectious colitis cases are caused by bacteria, which is why your provider may prescribe antibiotic treatment.

However, in other cases, antiviral or antifungal medication may be recommended.

Ischemic colitis 

Ischemic colitis is an injury of the colon that can occur due to reduced blood flow.

The condition is most commonly seen in people in their sixties to seventies with a history of atherosclerotic disease (when cholesterol, fats, and other substances collect in artery walls). 

The symptoms of ischemic colitis can be diverse, making it especially challenging to diagnose.

Symptoms of ischemic colitis can include:

  • Bloody stool
  • Abdominal pain
  • Leukocytosis (high white blood cell count)

In some cases, the condition can resolve on its own.

Other times, your provider may recommend antibiotics, intravenous fluids, or surgery.

Colon cancer

In severe cases, blood clots in stool can be a sign of colon cancer. 

Additional symptoms of colon cancer, if present, can also include:

If you’re experiencing any of the above symptoms, it’s important to reach out to your healthcare provider as soon as possible.


Polyps that grow on the inner lining of the colon or large intestine can also cause blood clots in stool.

Polyps are a result of genetic changes in the cells of the colon. 

Most polyps don’t cause symptoms early on, but when they do occur, you may experience: 

  • Blood in stool
  • Anemia or weight loss
  • Change in normal bowel movement patterns
  • Abdominal pain (rare)

If you’re experiencing symptoms of a colon polyp, it’s important to speak to a healthcare professional about testing. When left untreated, colon polyps can lead to cancer.

Hemorrhoids or anal fissures

Hemorrhoids are swollen veins in your lower rectum; these can form either internally (in the lower rectum) or externally (around the anus).

These areas can cause discomfort and rectal bleeding. 

Anal fissures are small tears in the anal mucosa that cause rectal bleeding and pain.

Both hemorrhoids and anal fissures can both be easily diagnosed by a healthcare provider doing an exam or, at times, by gathering a complete medical history. 

Gastric antral vascular ectasia

Gastric antral vascular ectasia (GAVE syndrome), also called watermelon stomach, is a rare but significant cause of GI bleeding in the elderly.

Unfortunately, the exact cause of GAVE syndrome is unknown, but it can cause bleeding in the GI tract and stool, as well as abdominal pain and chronic iron-deficiency anemia.

Treatment options vary from prescription medication and endoluminal therapies to surgery. 

Inflammatory bowel disease (IBD)

Inflammatory bowel disease (IBD) describes inflammation within the digestive tract.

Two specific conditions encompass IBD: Crohn’s disease and ulcerative colitis (UC).

Common IBD symptoms include:

While there is no cure for IBD, anti-inflammatory medications, corticosteroids, antibiotics, biologics, and immunomodulators can help relieve symptoms. 

Treatment of Blood Clots in Stool

There are many possible treatment options for blood clots in stool.

The right treatment option for you will depend on the exact cause of the blood clots in your stool, which is why speaking with a healthcare provider is the best way to get the treatment and care that you need. 

When speaking with your provider, they will ask you questions about your symptoms and health history.

They may also want to perform a physical exam of your rectum and anus in some cases. 

When needed, your provider may order tests to help inform diagnosis and treatment recommendations.

These testing options may include:

  • A colonoscopy
  • A sigmoidoscopy
  • A fecal occult blood test

Mucus in Stool

In healthy adults, mucus in stool can be a common occurrence caused by diet, dehydration, or constipation.

But bloody mucus in stool can be a sign of a more serious condition.

Bloody mucus

Bloody mucus in stool can be a sign of a serious condition, including:

  • Inflammatory bowel disease (Crohn’s disease or UC)
  • An infection
  • Cancer

It’s important to speak to your healthcare provider if you notice bloody mucus in your stool.

  • Inflammatory bowel disease (IBD)

  • Cystic fibrosis

Symptoms in adults that warrant immediate medical attention include:

  • Experiencing a sudden drop in blood pressure
  • Having a fast heart rate
  • Vomiting blood
  • Slipping into unconsciousness
  • Fainting
