What about flatulence in colon after exercise?

There are three sources of qi in the intestine: one is the air swallowed with diet; The second is produced by enteric bacteria's decomposition of food and food fermentation; Third, blood diffuses into the intestine. Therefore, when abdominal flatulence occurs, you can take care of it from the following four points.

(1) Eat less food that is easy to produce gas. For example, the sugar contained in beans cannot be digested and absorbed by enzymes in the gastrointestinal tract, but it is easily digested by colon bacteria. Lactose in milk can't be completely absorbed, so we should eat less food such as soybeans, red beans, sweet potatoes, chestnuts, peanuts and dairy products, beer, soda and so on.

(2) Don't wolf down when eating, so as not to swallow too much gas. In addition, don't eat too much, and don't lie flat immediately after meals.

(3) Don't induce hiccups intentionally, because doing so will make more gas swallow into the stomach and aggravate abdominal distension.

(4) Take part in regular physical exercise and exercise abdominal muscles: You can also learn Qigong and do internal work, mainly relying on supine abdominal breathing to promote gastrointestinal peristalsis and make gas easily excreted.
