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 passes into Barrett's esophagus - a precancerous condition. Jonathan Aviv, professor of otolaryngology and an internationally recognized doctor, has developed an author's methodology for treating dangerous symptoms based on dietary changes and the implementation of daily minimal physical activity. All recipes are easy to prepare, and workouts and breathing recommendations are available to someone of all fitness levels. The system of 28-day reduction of acidity in the body and getting rid of symptoms of GERD includes 2 phases: 1 - exclusion of industrial and natural products with high acidity; 2 - return to the diet of part of the prohibited products. The idea is to give the body a break so that the enzyme pepsin, which is responsible for eating the esophagus, is completely removed from this organ.
