A stomach ulcer can occur as a result of gastritis that was left untreated. It is characterized by the appearance of a wound on the stomach lining, which can worsen after meals (which is when the release of stomach acid is stimulated).

Although diverticula and any associated inflammation are usually seen in the lower intestines, they can become swollen in the upper intestines, causing upper stomach pain.

Other common symptoms include nausea, vomiting, fever and stools with blood.

How to relieve: Diverticulitis treatment should be monitored by a gastroenterologist. The treatment approach will depend on the intensity of the symptoms and the underlying cause of the inflammation. The doctor may prescribe analgesic medication and/or anti-inflammatory medication to relieve symptoms, as well as antibiotics, like ciprofloxacin and metronidazole, to treat or prevent any infections.
