Ulcers – An Introduction

An ulcer is an erosion or open sore, on any area of skin or mucous membrane that is lacking its normal protective cover and, is inflamed. The different types of ulcers are classified according to the location they are found in the body. They can be the most common peptic ulcer, found in the digestive tract as well bedsores or genital ulcer as well.

Our stomach produces acid to help with the digestion of food and to kill bacteria. This acid is corrosive, so some cells on the inside lining of the stomach produce a natural mucus barrier which protects the lining of the stomach so a balance between the amount of acid that you make and the mucus defence barrier is maintained. A digestive tract ulcer may develop if there is an alteration in this balance allowing the acid to damage the lining of the stomach. Also, bed sores are caused by pressure against the skin that inhibits an adequate supply of blood to the skin and underlying tissues.

Ulcer is famous to be caused mostly by bacteria but some are caused by other pathogens as well. The most famous bacterium, named Helicobacter pylori (H. pylori), was established as the leading cause of peptic ulcers in the early 1980s. H. pylori are a spiral-shaped bacterium that can live and grow on the lining tissues of the stomach.

In some case, people getting infected with H. pylori start to develop the symptoms of infection. But in some people, symptoms of ulcer are never developed though they are infected with H. Pylori. It remains unclear why some people develop symptoms of the infection and others do not.

Medicines of a great variety are provided apart from anti-biotic for its treatment.
Ulcer can occurs on skin, in mouth, in epithelial tissues, in mucus membrane but mostly in the lining of digestive tract. Seven different types of ulcers just belong to the digestive tract.
