That was two or three years ago, when I ate a little more, my stomach began to swell, but when I didn't, my appetite was normal, but I didn't dare to eat more. If I eat too much, my stomach will swell. For flatulence, first of all, we should exercise more and eat less greasy and irritating food. In addition, in terms of diet, three meals a day should be distributed fairly, and hunger and satiety should be average. Generally, you should eat eight points full, and don't overeat to adapt to the digestive ability of the gastrointestinal tract. It is suggested that you don't sit on the sofa all the time after dinner. You can get up and walk, wash a bowl or take a walk. Gentle and gentle exercise helps digestion and is effective in treating flatulence.
