Endoscopy

An endoscopy may help your doctor determine what's causing digestive signs and symptoms, like nausea, vomiting, abdominal pain, difficulty swallowing and gastrointestinal bleeding. Scopes have a small camera attached to an extended , thin tube. The doctor moves it through a body passageway or opening to ascertain inside an organ. Sometimes scopes are used for surgery, like for removing polyps from the colon.
