MORE ABOUT ULCER

What does ulcer mean?

An ulcer is a sore on the skin or on a mucous membrane, such as the lining of your stomach. If left untreated, ulcers can result in serious health problems, such as inflammation or death of tissues.

Ulcers in the stomach are fairly common in Western countries. They are generally easy to treat but can become serious if not treated.

Example: The doctor discovered that an ulcer was causing my stomach pain.

Where does ulcer come from?

The first records for the word ulcer come from around 1350. It ultimately comes from the Latin ulcus, meaning “a sore or ulcer.”

The most common variety of ulcer is the peptic ulcer, which occurs in the stomach or small intestine. Symptoms of ulcers include nausea, heartburn, and pain.

Ulcers by themselves are not usually serious and can easily be cured with antibiotics. However, if not treated, they can lead to more serious problems, such as holes in the stomach tissue or infections.

It was once thought that ulcers were caused by stress or acids. Today we now know that ulcers are caused by bacteria or as a side effect of certain medicines, such as aspirin or anti-inflammatory drugs.
