Diarrhea – Diagnosis

The cause and treatment of diarrhea may be very simple, such as discontinuing magnesium- containing antacids. Or it may be more difficult. Testing of blood and stool may be needed. X-rays and ultrasound may also be necessary. In some cases, sigmoidoscopy or colonoscopy are required to visually inspect the colon with a lighted, flexible tube. Testing depends on how severe and prolonged the condition is, and how the physician evaluates a specific case.
