Slow peristalsis is related to intestinal dysfunction, improper diet and imbalance of intestinal flora. There are more triggering reasons for intestinal dysfunction, such as intestinal stimulation and emotional distress, etc. Not only will intestinal peristalsis be slow during the attack, but also the secretion and absorption function will be impaired, and then symptoms such as gastric distension, stomach pain, bloating and constipation will appear. Some people have slow peristalsis due to improper dietary habits, such as too fine food in the diet, the dietary fiber content in food is relatively small, the stimulation of the intestines will be reduced accordingly, because the intestines do not get enough stimulation, long-term will also lead to slow peristalsis. The intestinal tract contains a large number of flora, under normal circumstances, harmful bacteria and beneficial bacteria are mutual checks and balances, once there is an imbalance in the intestinal flora, the excessive growth of harmful bacteria in the intestinal tract will affect the intestinal function, and therefore will also induce slow intestinal peristalsis.
