Peptic ulcer is a disorder of the digestive system that causes inflammation and lesions in different regions of the gastrointestinal tract. The disorder involves erosion of the mucus-covered protective surface of either the stomach or the duodenum.
Most peptic ulcers occur on the premises of genetically inherited physiological abnormalities, such as: inappropriate production of mucus (a natural protective substance that surrounds the internal soft tissues and organs), inappropriate production of bicarbonate (a chemical that neutralizes the effects of digestive acids) and poor blood circulation at the level of the stomach.
The major cause of peptic ulcer is infection with a type of bacterium called Helicobacter pylori. Although there are various other factors that contribute to the development of peptic ulcer, the disorder generally occurs as a consequence of infection with Helicobacter pylori bacteria. These bacteria weaken the internal organs protective walls, allowing gastric acids and pepsin to cause serious damage to soft tissues and organs.
Another cause of peptic ulcer is the stomachs overproduction of digestive fluids. In normal amounts, gastric...
