Everything you need to know about stomach ulcers.

Stomach ulcers are sores in the lining of the stomach or small intestines. They occur when protective mucus that lines the stomach becomes ineffective.

The stomach produces a strong acid to help in digestion and protect against microbes.

Some ulcers are easy to cure, but can cause significant problems if uncured. 

Also known as Gastric ulcers.


1. Bloating. This means your stomach swells because your stomach is full of gas or air.

2. Retching. Also known as heaving. This means sounding and looking as though you are about to be sick (vomit) but not necessarily vomiting.

3. Feeling sick(nausea).

4. Vomiting.

5. Feeling very full after a meal.

6. Acid reflux.

7. Dark, tarry stool.
