A stomach ulcer is a sore that develops on the lining of the stomach. It can cause a variety of symptoms, including abdominal pain, bloating, nausea, and vomiting. If left untreated, a stomach ulcer can lead to serious health problems, such as bleeding and perforation. Checking for stomach ulcers is, therefore, important for early diagnosis and treatment.
There are several ways to check for stomach ulcers at home and in clinical settings.
