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 can be caused by a number of factors. Stress increases the stomachâs output of acid, which can erode the stomachâs lining. Long-term use of non-steroidal anti-inflammatory drugs (NSAIDs), a type of pain killer, can also increase acid production, and itâs well known that a diet of spicy and citric foods can result in ulcers. Some factors are outside of lifestyle changes, however. Many peptic ulcers are caused by a bacterial infection known as Helicobacter pylori.
