Bloody stools

Bloody stools refer to the condition where blood is present in the feces. This can be a symptom of various medical conditions, ranging from minor issues to serious diseases. The blood in the stool can be visible to the naked eye, or it may only be detectable through a fecal occult blood test.

Causes

Bloody stools can be caused by a variety of conditions. Some of the most common include:

• Hemorrhoids: These are swollen blood vessels in the rectum or anus that can bleed during bowel movements.
• Anal fissures: These are small tears in the lining of the anus, often caused by constipation.
• Gastrointestinal bleeding: This can occur anywhere in the gastrointestinal tract, from the mouth to the anus. It can be caused by conditions such as peptic ulcers, gastritis, or colorectal cancer.
• Diverticular disease: This condition involves small pouches, or diverticula, that develop in the lining of the intestine and can bleed.

Symptoms

In addition to the presence of blood in the stool, other symptoms may accompany bloody stools, depending on the underlying cause. These can include abdominal pain, changes in bowel habits, weight loss, or fatigue.

Diagnosis

The diagnosis of bloody stools typically involves a medical history and physical examination, as well as tests such as a colonoscopy, sigmoidoscopy, or upper endoscopy. A stool test may also be used to detect hidden blood in the stool.

Treatment

Treatment for bloody stools depends on the underlying cause. This can range from over-the-counter treatments for conditions like hemorrhoids and anal fissures, to surgery for conditions like colorectal cancer.
