Stomach ulcers. Symptoms and Causes

Definition of ulcer
An ulcer is a loss of substance, ie a circumscribed erosion of the skin surface or mucous membrane and has little tendency to heal by granulation and healing process, by contrast, tends to spread and deepen surface.

Causes of ulcers
The ulcer may be caused by many reasons:
* Physical: burns, frostbite, radiation.
* Chemicals: caustic substances.
* Microbial ulceration of tuberculous nodules of sifilomas, etc..

Duodenal ulcer
Ulcer, duodenum (first portion of the intestine located below the stomach), unlike gastric ulcer, occurs more often in men than in women. In 95% of cases the location of the ulcer is the first portion of the duodenum near the pylorus, opening communication between the stomach and duodenal intestine.

Duodenal ulcer is usually round as gastric ulcer and may lead to the same complications:
* Bleeding from erosion of a blood vessel.
* Perforation of the duodenal mucosa with consequent peritonitis of a serious nature.

Symptoms of duodenal
Symptoms of duodenal highlight:
* Pain generally radiates to the right (liver area)
* The pain usually occurs much later food intake in gastric ulcer. In duodenal ulcer usually occurs at 3 or 4 hours after the last meal, or later.
* The pain subsides when it gets to eat food.
* Its complications (bleeding duodenal mucosal perforation) may be less common than gastric ulcer.

Gastric ulcer or stomach
The stomach mucosa may ulcerate for various reasons.
* Tuberculous gastric ulcer (rare and are diagnosed at autopsy because they can not cause discomfort).
* Syphilitic sores.
* Ulcers cancer
* Ulcers typhus
* Ulcers angry
* By eating hot
* Ingestion of caustic substances (acids, alkalis, etc.).

But to say simply gastric or stomach ulcer means a particular pathology of the stomach whose origin is not known exactly.

The stomach ulcer often more or less round and has a size of 1-2 cms. in diameter or more.

Its most common location is the small curvature or the area near pylorus orifice of communication between the stomach and duodenum.

Theories of the causes of stomach ulcers
In the course of medical research have been many theories about the causes of stomach ulcers in an attempt to explain the origin of this condition. To mention in passing some of these theories point out the following:
* Vascular theory. Ulcer caused by local nutritional defect due to thrombotic occlusion.
* Nervous or neurogenic theory. The ulcer would arise from a state of vagotonia, ie autonomic nervous system imbalance in favor of vague with the occurrence of spasms in some gastric arteries that would not provide sufficient amount of blood to nourish the area of the affected mucosa.
* Theory anaphylactic. A state of local produce anfilaxia spasm of some of the gastric arteries with similar consequences to the theory nervous.
* Theory inflammatory. It relates the ulcer with an infectious inflammatory condition limited to a small area of the stomach mucosa.
* Theory of hormonal or vitamin deficiencies (vitamin B).

But among the theories that seem to relate more with gastric ulcer would be:
* The gastric hyperacidity
* The lifestyle food and medicines
* And the infection of the bacterium Helicobacter pylori.

Gastric hyperacidity
Has been associated with stomach ulcers digestive action of gastric juice at a point of the stomach mucosa that had lost its natural resistance to the action of gastric juices. Put another way, would be like an autodigestion of the weakest area of the gastric mucosa.

This theory also raises two questions:
* What have been the earliest changes that have weakened that portion of the stomach mucosa ulceration that would result from the action of gastric juice hyperactive?
* Why gastric juice acquires this state of hyperactivity to digest a portion of the gastric mucosa less vitality?

In response to this second question is cloropéptica theory. According to this theory the ulcer would arise from the excessive secretion of hydrochloric acid from the secretory glands. And that would be caused by a state of acidosis of the blood. There is evidence that in fact many cases of stomach ulcers are accompanied by hiperclorihidria, but also established that there are always two are related, since there are cases of ulcer without excess hydrochloric acid, and cases of excess hydrochloric acid without ulcers.

The lifestyle food and medicines
Recent studies find that the style of living and eating habits may be associated with stomach ulcers.
* Caffeine stimulates acid secretion in the stomach and therefore may contribute to the formation of stomach ulcers.
* The snuff. It has been proven to slow the healing of stomach ulcers and contributes to its recurrence.
* Stress. Many people and research relating emotional stress to the formation or recurrence of stomach ulcers.
* The NSAIDs, ie ibuprofen, aspirin, etc.. cause a weakness of the stomach mucosa that would make it more sensitive to the action of gastric juice.
* Food allergies caused by intestinal hyperpermeable translates into a constant release of histamine. Histamine acting on H2 receptors stimulates the release of gastric juice (pepsin, intrinsic factor).

Helicobacter pylori and stomach ulcers
Research conducted in 1981 by the gastroenterologist Barry Marshall, the University Medical Center of Virginia (USA), confirmed that Helicobacter pylori in the stomach was 90 per cent of patients with ulcer.

It appears that the bacterium is protected from the acids hiding under the mucous covering the gastric cavity and resisting the action of hydrochloric acid.

Again it is believed that Helicobacter pylori and camouflaged once, causing inflammation of mucous membranes and in extreme cases, it erodes and destroys the stomach lining, leading to the development of peptic ulcer. Increasingly, doctors and researchers attribute stomach ulcers to the action of this bacterium.

Symptoms of gastric ulcer or stomach

There are mute or silent ulcers that do not manifest any symptoms until there is no perforation of the gastric wall leading to acute peritonitis.

However in the majority of ulcers are the following:
* Painful Acid dyspepsia, which appears each time you eat food. A half hour or so of eating a person feels pain of burning rate (as if pouring hot water on a wound).
* Burning stomach.
* Some vomiting.
* If the situation involved and the disease process is ongoing:
* Gastric hemorrhage. Blood can be seen in the vomit or stools.
Anemia if bleeding not corrected.
* Gastric perforation with peritonitis. In this situation, the pain is sharp, stabbing, stabbing as

Other complications of stomach ulcers
In addition to bleeding and perforation may be other complications:
* Pyloric stenosis (narrowing of the orifice of the pylorus)
* Perigastritis (Linings peritoneal inflammation of the outer surface of the stomach.
* Cancerificación of the ulcer (implantation of cancer in the ulcerated area).
