Always indigestion is related to poor dietary habits, gastrointestinal dysfunction and imbalance of intestinal flora. Some people like to eat spicy, greasy, stimulating food on the diet, although it will cause sensory stimulation, but it will affect the function of the stomach and intestines, and often eat this kind of food will lead to a heavier burden on the digestive system, which will induce indigestion. When the gastrointestinal system has gastrointestinal dysfunction, the peristaltic ability of the intestines and stomach is relatively weak, and the secretion of digestive juices will be relatively lacking, so that it is impossible to digest and decompose food, resulting in indigestion. There is a large amount of bacteria in the intestinal tract, and in a balanced state, the intestinal tract can normally absorb the nutrients in the food and the peristaltic function is also normal. Once there is an imbalance of intestinal flora, it will lead to low intestinal function, the secretion of intestinal fluid will be relatively reduced, and the absorption ability will be gradually weakened and induced indigestion.
