Document Summary
Lecture 12 drugs and the gastrointestinal tract. Ulcer in an area of the gastrointestinal tract that is usually acidic and thus extremely painful. Bacteria in the stomach (specifically a type called helicobacter pylori), which is very common and the use of anti-inflammatory painkillers e. g. nsaids or aspirin, especially when taken long term are the 2 primary causes of ulcers. Alcohol, caffeine, and smoking have been linked to peptic ulcers. Abdominal pain, classically epigastric with severity relating to mealtimes, around 3 hours of taking a meal. Hernatemesis (vomiting of blood); this can occur due to bleeding directly from a gastric ulcer, or from damage to the esophagus from. Rarely, an ulcer can lead to a gastric or duodenal perforation. This is extremely painful an requires immediate surgery. First of all, it is necessary to stop taking these medications. Under special circumstances, the physician may find it necessary for the patient to continue with nsaids.
