We know that long-term constipation on the human body has certain hazards, it should be actively prevented, especially functional constipation, the formation of its causes and mental disorders, food less or partial food, lack of fiber or vitamins in food, neglect timely defecation, lazy activity and exercise, long-term laxative defecation and other bad habits. Therefore, the emphasis on prevention, mainly by self-regulation, according to scientific and hygienic methods to correct bad habits. Specific methods are: 1, to develop the habit of regular defecation: colon movement has a certain regularity, in the morning after waking up with the person from lying down to stand up, upright reaction will occur, the colon has a large group peristalsis, pushing feces down into the rectum, causing defecation reflex. So constipated people should intentionally go to the toilet in the morning squatting for about 5 minutes, after a period of time to establish a normal defecation habit. Can vary from person to person, to develop a daily bowel movement once a day, at noon or evening, which is not a one-size-fits-all. 2, to pay attention to breakfast: after breakfast can cause gastrocolonic reflex, conducive to fecal movement. Constipation, if you can pay attention to breakfast, take advantage of the situation, early in the morning after breakfast to defecate naturally easier to discharge. 3, reasonable arrangement of life and work: to go to bed early and get up early, get up early for a moment, a moment of activity, timely breakfast, can be comfortable defecation. Get up late, to rush to work, often unable to eat breakfast, relieve stool, disrupting the normal physiology, most likely to cause constipation. For the sedentary less active brain workers, to combine work and rest, appropriate to participate in sports and cultural activities, as the saying goes, “activity, activity, stool since the passage. Run, walk, do deep breathing exercises, turn around to move the waist, etc., can make the gastrointestinal activities to strengthen, appetite, abdominal muscles, diaphragm, thigh muscles to get exercise, so that smooth and fluent bowel movements. 4, adjust the diet structure: eat more fiber, vitamin food. Fine white rice, white flour, refined meat, eggs, canned fruits and vegetables such as fiber and vitamins have been destroyed, it seems that the food advanced, tasty to eat, but not necessarily in line with science. Europe and the United States and other countries with a refined diet, a lot of people constipated, the incidence of colon cancer is also very high, so the more mixed staple foods eat the better, cellulose on the intestinal wall stimulation, conducive to defecation. The elderly have bad teeth, you can “swallow the whole” type of vegetables, fruits, coarse has the benefit of coarse, these are not easy to chew the rotten cellulose, is the good medicine for laxative. Milk, cold water can laxative, there are advocates of the morning after waking up a glass of cold water is better than eating laxative, in addition, black sesame, honey, walnuts can also laxative. 5, do not abuse laxatives: often serve can lead to habitual, dependence and even addiction to laxatives; long serving to the intestinal mucosa stress weakening, resulting in increasing the amount of laxatives; long serving laxatives can cause gastrointestinal dysfunction, but aggravate constipation.
