This is a
painful sore or crater on the side of the stomach or in the small intestine. The following symptoms may occur:
Vomiting, nausea, weight loss, poor appetite, bloating, burping and abdominal pain.
For a long time, it was believed that peptic ulcers occurred because of lifestyle elements because it is usually the sinful things we love that make ulcers flare up: coffee, Coke, cigarettes, alcohol, chocolate, citrus juice etc. Stress also makes them worse so I guess peptic ulcers are not God's punishment after all. In a recent discovery, researchers found that most ulcers are caused by a bacterial infection called Helicobacter pylori(H. pylori). It is not known what causes this bacteria, some speculate it may spread through food, water or the saliva of an infected person.
Once it is detected, doctors can prescribe antibiotics and it will most likely be gone.
