Red Stool Symptoms
While everyone's frequency of bathroom trips varies, there are a few things that should remain constant. Variances in stool shades is to be expected based on your individual diet but red stool symptoms can be concerning.
Every incident of red stool should be taken seriously. Causes can be simple and treatable, like hemorrhoids, or signal a more serious condition that requires medical intervention.
If you're experiencing red stools, any of the following associated red stool symptoms could be ailing you as well.
Generally, bright red blood found sitting in the toilet bowl or on toilet paper is a sign of an issue in the lower rectum or anus. But blood that is mixed in with stool signals a problem higher up in the bowel.
Stool can have a bright red color, but more common colors are maroon and black. Stool can also have a tarry appearance. In some cases, blood isn't noticeable at all, even though it's present. This is classified as occult blood and only detected by stool tests.
If the cause is higher in the bowel, it is usually more serious but not always dangerous. Read more in our red stool causes section to determine how concerned you should be about your red stool.
Red Stool Causes Overview
Red stool should never be ignored. But not all causes are considered a medical emergency. You'll find a variety of red stool causes in our list, most which shouldn't cause alarm.
- Foods: Processed foods are filled with dyes. Eating something heavy in red dye can affect the color of your stool. Eating an excess of red foods, like beets, can also alter stool's shade. A diet lacking in fiber can lead to straining and consequently, red stool symptoms.
- Viral: If the health of your digestive system is attacked by a virus, the nature and color of your stool can be one of the first symptoms. Rotavirus is one example. Children who receive the Rotavirus vaccine can experience red stool as a side effect. Always speak to your child's pediatrician immediately if they experience this.
- Bacterial: E. coli is a common bacterial infection that causes an intestinal infection. While it affects everyone to different degrees, red stool is one possible symptom.
- Rectal trauma: Anal fissures are one example of trauma that can cause red stool. A tear in the lining of the lower rectum can bleed during bowel movements and cause red stool.
- Internal bleeding: If there is blood anywhere in the digestive tract, it can result in red stool. One example is a Mallory-Weiss tear, or a tear in the mucous membrane of the esophagus.
- Medications: Bismuth, the active ingredient in Pepto-Bismol, can alter the color of stool. The darker shade can be mistaken for red stool.
- Diseases: There are a wide range of diseases that list red stool as a possible symptom. Everything from hemorrhoids to Crohn's disease to cancer can cause changes to stool. If there is no obvious reason behind your red stool, seek medical help in finding a diagnosis as there are serious potential causes.
There are several tests that may be conducted to determine your cause of red stool symptoms if it's not obvious such as:
- Full medical history and physical exam including a rectal exam
- Testing stool for occult blood
- Endoscopy to view the esophagus and stomach to check for bleeding sources
- Colonoscopy to check for bleeding sources in the colon and rectum
- Barium x-ray to check the digestive tract

FAQs About Red Stool
Here are some frequently asked questions about red stool.
Can certain foods cause red stool?
Yes, certain foods can cause red stool. Most commonly, red foods like tomatoes or beets can cause a red-tinged stool. Additionally, any food with large amounts of red food coloring can cause a red tinge to fecal matter. If you have no known cause for redness in your stool, it may be caused by bleeding and should be evaluated by a physician.
Why am I pooping blood with no pain?
Painless blood in stool can be caused by many things, including colon cancer, hemorrhoids, diverticulosis, diverticulitis, and angiodysplasia. The most worrisome of these is cancer, and there is no means of determining if blood is or is not caused by cancer. If you suspect cancer you should seek medical evaluation. Hemorrhoids that are painless are internal and sometimes cannot be seen. Diverticulitis can cause infection and bleeding, but may also require a colonoscopy to be seen. Angiodysplasia is more common in elderly individuals and also requires medical evaluation to identify.
Is it normal to poop with blood?
No. It is not normal to have blood in or on feces or in the toilet bowl. There are many causes of blood in feces or in the toilet bowl. Some of these causes are dangerous and others are benign and self-limited (will resolve on their own). However, because the dangerous causes can only be identified by a medical professional, you should seek evaluation to determine if any additional steps should be taken.
Why is my stool dark red?
Dark red or maroon stool (melana) can be caused by consuming food that color the stool red, such as beets or tomatoes, but can also be caused by bleeding in the lower intestinal tract. Because often the cause cannot be determined, it is wise to seek medical evaluation. GI bleeding is more common in elderly individuals, individuals with a personal or family history of cancer, celiac disease or infections. You should seek medical evaluation to rule out the more dangerous causes like cancer or inflammatory bowel diseases.
Why is my stool bright red?
Bright red stool (hematochezia) is usually a sign of bleeding near the anus. A common and benign cause of bright red blood in the toilet is an anal fissure. This is usually accompanied by a ripping or burning sensation as stool is passed, followed by blood in the bowl, on the feces, or on the toilet paper. It often follows constipation or a particularly hard stool, and takes time to heal in which an individual should consume foods and supplements that produce soft stools. Lower GI bleeding in the distal colon or the rectum can also cause hematochezia.
