Occult bleeding may be a symptom of inflammation or a disease such as colorectal cancer. A simple lab test can detect occult blood in your stool.

What causes GI bleeding?

Many conditions can cause GI bleeding. A doctor can try to find the cause of your bleeding by finding its source. The following conditions, which are listed in alphabetical order, include possible causes of GI bleeding: Angiodysplasia. Angiodysplasia is when you have abnormal or enlarged blood vessels in your GI tract. These blood vessels can become fragile and bleed. Benign tumors and cancer. Benign tumors and cancer in the esophagus, stomach, colon, or rectum may cause bleeding when they weaken the lining of the GI tract. A benign tumor is an abnormal tissue growth that is not cancerous. Colitis. Ulcers in the large intestine are a complication of colitis. Ulcerative colitis is an inflammatory bowel disease that can cause GI bleeding. Colon polyps. Colon polyps can cause GI bleeding. You can have more than one colon polyp at a time. Some types of polyps may be cancerous or can become cancerous. Diverticular disease. Diverticular disease can cause GI bleeding when small pouches, or sacs, form and push outward through weak spots in your colon wall. Esophageal varices. Esophageal varices can cause GI bleeding. Esophageal varices are usually related to a chronic liver condition called cirrhosis. Esophagitis. The most common cause of esophagitis is gastroesophageal reflux (GER). GER happens when your lower esophageal sphincter is weak or relaxes when it should not. Stomach acid can damage your esophagus and cause sores and bleeding.

Gastritis. Some common causes of gastritis include

the use of nonsteroidal anti-inflammatory drugs (NSAIDs) and other medicines

infections

Crohn’s disease

serious illnesses

severe injuries

If untreated, gastritis can lead to ulcers or worn-away areas of the stomach lining that can bleed in your GI tract. Hemorrhoids or anal fissures. Hemorrhoids can cause GI bleeding. Constipation and straining during bowel movements cause hemorrhoids to swell. Hemorrhoids cause itching, pain, and sometimes bleeding in your anus or lower rectum. Anal fissures are small tears that also can cause itching, tearing, or bleeding in your anus. Mallory-Weiss tears. Severe vomiting may cause Mallory-Weiss tears, which can cause GI bleeding. You can have more than one Mallory-Weiss tear at a time. Peptic Ulcers. The bacteria Helicobacter pylori (H. pylori) and use of NSAIDs can cause peptic ulcers. Peptic ulcers can wear away your mucosa and cause GI bleeding.

Doctor's Notes on Stool Color Changes

Stool color changes refer to unusual or different colors found in the stool (feces). Many things can cause the stool to change color temporarily, including your diet. Beets and green vegetables, in particular, may alter stool color. Other conditions that can cause changes in stool color include certain medications, hemorrhoids, ulcerative colitis, gallbladder disease, and celiac disease, among others. Any condition that can cause bleeding into the gastrointestinal tract can cause blood in the stool and a change in color to bright red or black. Symptoms and signs associated with changes in stool color depend on the reason for the change. These can include rectal bleeding, diarrhea, abdominal pain or cramping, hemorrhoids, and the passage of mucus in the stool. Stool color changes related to diet or medications may not be accompanied by other symptoms.

What Is the Treatment for Stool Color Changes?

Changes in stool color are a symptom and not a condition; therefore, treatment will be directed at the underlying condition that caused the color change. Some changes in stool color may be related to dietary factors or medication use and do not require treatment.
