There are many ways to avoid flatulence. Chronic flatulence or belching is the result of fermentation in the small and large intestines. It can occur because you have swallowed too much air; your fermentation process is out of balance (the result of an excess of magnesium and a deficiency of sodium and calcium in your food); you have eaten too fast; or you are ill.

Be silent when eating to avoid swallowing air. Chew food thoroughly.
