Diarrhea
Diagnosis
The
cause and treatment of diarrhea may be very simple, such as
discontinuing a food, a drug, over-the-counter medication or sorbitol
containing chewing gum. However, at times the diagnosis may be more
difficult. Testing of blood and stool may be needed. X-rays and
ultrasound may also be necessary. Often, colonoscopy is 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.
