Le reflux gastro-œsophagien chez l’adulte


Gastroesophageal reflux disease GERD is a disease of the digestive tract that affects the esophagus. The esophagus connects the throat with the stomach, from which it is separated by a muscle called the lower esophageal sphincter SOI. When this muscle is not functioning properly, the contents of the stomach can move up into the esophagus and damage its lining, which is not made to tolerate the acidity of stomach fluid. GERD can be erosive or non-erosive. Erosive GERD presents with inflammation, erosions, or ulcers in the esophagus. Non-erosive GERD is the most common and does not present with inflammation, erosions or ulcerations. d’ulcérations.


Symptoms of GERD may include tooth corrosion, burning sensation starting in the stomach and moving up to the mouth heartburn after meals or when lying down, bitter-tasting regurgitation in the mouth, difficulty swallowing, dysphagia, pain in the mouth odynophagia swallowing, sore throat, cough, and chest pain unrelated to the heart. au cœur.


Treatment for GERD may include a medical approach eg. : drugs to reduce gastric acidity, a nutritional approach as well as behavioral modifications. In some cases, surgery, called a fundoplication, may be necessary.e. 

Nutritional approach

The nutritional approach includes five key points::


  1. Increase lower esophageal sphincter pressure SOII)

The lower esophageal sphincter is the muscle that separates the base of the esophagus and the stomach. When the pressure is right, it stops the acidic contents of the stomach from going back up into the esophagus. Certain foods contribute to increasing the pressure of the SOI. This is especially the case for foods high in protein, such as lean meat and low-fat dairy products. On the other hand, certain substances decrease the tension of the SOI and are to be avoided. This is the case with excess fat, alcohol, certain drugs, tobacco, mint and methylxanthines, compounds naturally present in chocolate, tea and coffee. le café.
