Heartburn typically results from excess acidity in the stomach or from improper operation of your digestive system. At the point where the esophagus and stomach join, a special muscle opens and closes the esophagus. When we swallow food this muscle relaxes to let the food pass into the stomach and after that it closes again. But it can happen that the muscle malfunctions. The components of the stomach then rise again up the esophagus, irritating the area. And this results in the infamous feeling of heartburn.
In order to stop it avoid acidic foods (lemons, etc.), alcohol, fat or fried food, food that is overcooked, coffee, juice, tomato base products and chocolate. But don’t deny yourself too much. You have to notice which foods bring on heartburn and avoid them. Also, don’t go to sleep right after the meal and don’t smoke, especially after meals.
