A person diagnosed with a gastric ulcer should be especially cautious if taking blood thinners. As reported by DrugNews.net, there have been several cases of pradaxa gastrointestinal bleeding emerging. Pradaxa, among other blood thinners, can increase the chance of major bleeding within the gastrointestinal tract, and should therefore be avoided by people suffering from any type of ulcer or intestinal disorder.
Peptic ulcers, which may be single or multiple, usually measure about 10 to 25 mm across and about 0.25 mm deep. The typical symptom is a gnawing pain in the abdomen when the stomach is empty.
Causes and incidence of peptic ulcersThe hydrochloric acid and pepsin released from the stomach wall, which help break food down, would quickly eat away the stomach and duodenum if other cells in the stomach lining didn't secrete a protective mucus. If this protective coating of mucus breaks down, the result is inflammation of the stomach wall (gastritis) or an ulcer.
Most ulcers occur in the first layer of the inner lining. A hole that goes all the way through the stomach or duodenum is called a perforation and is a medical emergency.
The most common cause of such damage is infection of the stomach by bacteria called Helicobacter pylori (H. pylori). Most people with peptic ulcers have these bacteria living in their gastrointestinal tract. Yet, many people who have such bacteria in their stomach don't develop an ulcer.
The following also raise the risk for peptic ulcers:
The incidence of gastric ulcers is about the same in men and women, but more males than females suffer from duodenal ulcers. Middle age is the most likely time for stomach or duodenal ulcers to develop, although the peak age for the development of duodenal ulcers is somewhat earlier than the peak age for gastric ulcers.
The lining of the duodenum is constantly at risk of erosion from acid produced by the stomach wall. The lower esophagus is at risk only when reflux of acid juice from the stomach occurs (acid reflex). Peptic ulcers in the jejunum occur only when there is a massive outpouring of gastric acid. In Meckel's diverticulum, a peptic ulcer may develop if misplaced gastric lining grows in the diverticulum.
Symptoms of peptic ulcersMany people found to have a peptic ulcer suffer no symptoms, but a greater number complain of a burning or gnawing pain in the abdomen, which sometimes wakes them at night. The pain of a duodenal ulcer is often relieved by eating, but usually recurs a few hours later.
Other possible symptoms include:
ComplicationsThe most common complication of a peptic ulcer is bleeding from the ulcer. Sever bleeding results in hematemesis (vomiting of blood) and melena (black feces), and is a medical emergency. Chronic bleeding may cause iron-deficiency anemia.
Rarely, an ulcer may perforate (make a hole in) the wall of the digestive tract and extend to the pancreas, usually causing pain that extends through to the back. If digestive juices leak through the perforation or if the perforation is on the front wall of the duodenum, the juices may cause peritonitis (inflammation of the abdominal lining), producing sudden, severe pain and requiring emergency hospital admission.
Chronic ulcers can cause extensive scarring of the stomach or duodenum, which may narrow the outlet of the stomach into the duodenum (a condition called pyloric stenosis) and thus obstruct the passage of food. The may cause vomiting and rapid weight loss.
A small number of gastric ulcers are malignant and should be removed as soon as they are diagnosed.
DiagnosisTo diagnose an ulcer, one of the following tests is carried out:
TreatmentTreatment for peptic ulcer involves a combination of medications to kill the H. pylori bacteria (if present), and reduce acid levels in the stomach. This strategy allows the ulcer to heal and reduces the chance it will come back. A peptic ulcer caused by H. pylori infection is usually treated with different combinations of the following medications for 5–14 days:
Other medications that may be used for ulcer symptoms or disease are:
PrognosisPeptic ulcers tend to come back if untreated. Medications, taken as directed, will clear up an H. pylori and make it much less likely than another ulcer will occur.
