Perforated Ulcer
Perforated ulcer occurs when a persisting ulcer burns through the lining of a certain part of the gastrointestinal tract (usually the stomach). A number of cases have been attributed to Helicobacter pylori bacterium; other causes include smoking and the use of nonsteroidal anti-inflammatory drugs (NSAIDS). Often, the first symptom is sudden and sharp abdominal pain which intensifies with sneezing or coughing.
