Flatulence and gurgling and exhaust are associated with eating too much gas-producing food, indigestion, incomplete intestinal obstruction, and imbalance of intestinal flora. Some foods are gas-producing foods, such as soybeans, sweet potatoes and potatoes, and when the food is digested, gas is released, thus leading to more gas and more exhaust in the digestive system. When the human body has indigestion, not only will there be a large amount of undigested food in the gut, resulting in bloating, but undigested food will also stimulate the intestines to produce a lot of gas, resulting in increased outgassing. Some people may experience incomplete intestinal obstruction, where the intestinal cavity is hyperdilated during an attack due to intestinal blockage, resulting in hyperactive bowel sounds. In some patients with partial obstruction, the body will release gas by peristalsis of the intestine below the site of obstruction in the form of venting. When the gas-producing bacilli in the intestine overgrow, it leads to an imbalance in the intestinal flora. This not only has an effect on the absorption function of nutrients, but also releases a large amount of gas, so it will cause the manifestation of bloated stomach and increased exhaustion.
