L’ulcère gastroduodénal


Peptic ulcer disease is an injury to the lining of the stomach ulcer stomach or duodenal ulcer duodenum, which then comes into contact with gastric acid secretions in the stomach or duodenum. It can also be found on the lining of the esophagus. The ulcer is characterized by a significant loss of substance from the internal gastric or duodenal mucous membrane wall, hollowing out this wall deep down to the muscular external layer.leuse.


The etiology of peptic ulcer disease is multifactorial. It generally occurs when there is an imbalance between the aggressive agents and the protective factors of the digestive mucosa, as it then becomes more sensitive to acidity. Aggressive agents can be internal endogenous, such as hydrochloric acid and pepsin which are secreted by the stomach, or external exogenous, such as pathogenic bacteria.athogènes (Helicobacter pylori), chemicals, aspirin and other nonsteroidal anti-inflammatory drugs NSAIDs, stress, etc. Defense factors of the digestive lining include mucus, bicarbonate, blood flow, cell epithelial tissue, and prostaglandins, hormones found in the body. The most common causes of peptic ulcer disease are infection withtion à Helicobacter pylori (H. pylori) and the use of NSAIDs.S.


The most common symptom of peptic ulcer disease is pain in the upper part of the epigastrium abdomen. This pain can sometimes be accompanied by nausea, vomiting, and weight loss.oids.

Medical treatment

Medical treatment for peptic ulcer disease may include the use of antibiotics to kill the bacteria.ie H. pylori, when this is the cause of the problem, and the use of drugs to decrease the secretion of acid inside the stomach or duodenum. In rare cases, surgical treatment to reduce acid production may be used.tilisé.

Nutritional approach

Studies do not show that a specific diet can promote healing or prevent recurrence of peptic ulcer disease. Thus, there is no specific therapeutic regimen for this disorder of the digestive tract. The goal of the nutritional approach is therefore to improve the well-being of the individual and to provide an adequate food intake, according to individual tolerance.elle.

Dietary recommendations

As there is no specific therapeutic diet for peptic ulcer disease, the dietary recommendations consist of promoting a balanced and individualized diet according to the problems, symptoms and individual intolerances to improve the comfort of the person. Dietary recommendations can include: :

  • Eat three meals a day andsnacks as needed, to avoid periods of prolonged fasting. Food usually helps to alleviate the symptoms of peptic ulcer disease, especially with duodenal ulcer.énal.
  • Consume an adequate amount of fiber eg. : fruits and vegetables, cereal products.).
  • Moderate the consumption of foods containing methylxanthines eg. : coffee, chocolate, cocoa, cola, caffeine and alcohol.ool.
  • Consume spices according to individual tolerance.
  • Stop smoking, as this slows down the healing process of ulcers and increases the risk of recurrence.

There is no specific therapeutic regimen for peptic ulcer disease. The food approach therefore does not cure or prevent the recurrence of this disease of the digestive tract. In the case of peptic ulcer disease, the nutritional approach aims rather to promote the comfort of the individual and to offer a balanced and individualized diet according to the tolerance of each person. Ultimately, the main dietary recommendation is generally to avoid foods that cause or worsen symptoms, tobacco and alcohol.l’alcool.
