â¢ Accidental poisoning is one of the leading causes of GI ulcer disease. This can be from plants (for example, toxic mushrooms, castor beans, or sago palm), pesticide or rodenticide toxicity, chemical poisoning (often with ethylene glycol or phenol), or heavy metal poisoning involving zinc, iron, or arsenic.
Peptic ulcers, open sores in the lining of the stomach, esophagus, or duodenum (the first part of the intestine), are common. Contrary to popular belief, ulcers are not caused by spicy food or stress. Instead, a type of bacteria called Helicobacter pylori is usually to blame. Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil), can also cause ulcers.
