Heartburn, allergies, chronic cough, runny nose, belching, discomfort after eating - all these unpleasant symptoms can indicate a serious inflammatory process in the body. Acid damage to the gastrointestinal tract leads to the development of reflux disease, which, in the absence of diagnosis and treatment, often progresses to Barrett's esophagus - a precancerous condition. Jonathan Aviv, professor of otolaryngology and internationally recognized physician, has developed an original method for treating dangerous symptoms based on changing the diet and introducing a life of daily minimal physical activity. All recipes are easy to prepare, and training and breathing recommendations are available to people with any level of physical fitness. The 28-day system for reducing acidity in the body and getting rid of the symptoms of GERD includes 2 phases: 1 - exclusion of industrial and natural products with high acidity; 2 - return of some prohibited foods to the diet. The idea is to give the body a break so that the enzyme pepsin, responsible for eating the esophagus, is completely eliminated from this organ.
