The reason for more gas at night may be that the food eaten during the day is not well digested in the gastrointestinal tract, and the peristalsis of the gastrointestinal tract becomes slow, so that the food is not digested at night, or it may be caused by fatigue and weakness and indigestion. You need to take drugs that can help digestion, such as lactase tablets, stomach and appetite tablets, etc. You should also pay more attention to your diet and eat less spicy, cold and stimulating food. The exhaust is also likely to be caused by eating a lot of gas-prone foods during the day, such as onions and sweet potatoes, which can also lead to more exhaust at night. So in the normal diet, try to eat less gas-producing food, and also drink more water every day to promote the peristalsis of the gastrointestinal tract. If the situation has not improved, you also need to go to the hospital to check the stool routine and abdominal ultrasound, so as to get the specific cause.
