Constipation can be said to be a relatively common situation, many people in life have encountered constipation, once constipation has a lot of impact on our body, leading people to constipation what are the reasons? 1, bad habits Many people will be constipated mainly because of bad habits, if we have a good daily intake of coarse fiber food, which will lead to a reduction in stool volume, intestinal peristalsis slowed down, after which it is easy to constipation. Clinical experiments have found that the reflexes of the stomach and colon are related to the amount of food eaten, and if we eat less will also lead to constipation. We will also find some obese people will also lead to constipation, obese people are generally lack of exercise, so our intestines and stomach can not get sufficient exercise, resulting in constipation. Cultivate regular defecation habits whether for the elderly or young people are very important, if often neglected to stool, resulting in suppression of the defecation reflex is also prone to constipation. 2, mental psychological people’s mental factors on the human body can be said to be very large, usually if we have some suffering from obsessive-compulsive disorder, anxiety, depression and other symptoms, then these people are more likely to be constipated than ordinary people. So this situation to relieve constipation is the appropriate way to shift attention, more communication with family and friends, do not give themselves too much pressure. 3, systemic lesions, including Parkinson’s syndrome, uremia, diabetes, cerebrovascular accidents and other systemic diseases, are also able to cause constipation. 4, intestinal lesions, including rectal prolapse, tumors, hernias, inflammatory bowel disease caused by constipation. Intestinal lesions can cause functional outlet obstruction, which in turn leads to defecation difficulties. 5, age The middle-aged and elderly are the main group of constipation. With age, physical strength and food intake are significantly reduced, which in turn will lead to reduced secretion of digestive juices in the gastrointestinal tract, insufficient peristalsis and tone of the intestinal tube, muscle weakness, decreased gastrocolic reflex, weakened external anal sphincter and so on. A series of age-related gastrointestinal manifestations will lead to prolonged residence time of food in the intestinal tract and excessive water absorption leading to constipation. In addition, older people with Alzheimer’s disease tend to lose their defecation reflex, which in turn leads to constipation.
