Defecation should be regular, if often delayed defecation time, can make the defecation reflex weakened, causing habitual constipation. Therefore, in order to treat constipation, we must change the bad defecation habits and rebuild the normal defecation reflex and normal defecation function. First of all, to develop the habit of regular defecation, whether or not the intention to defecate, it is best to squat once in a fixed period of time. This time should be chosen in the morning after waking up or other time that you think is appropriate. Of course, the formality is not helpful. In the bowel movement to focus on the bowel movement, do not do other things such as reading books, listening to music, etc.. By developing the habit of regular bowel movements, you can increase the normal bowel reflex. Secondly, do not artificially control defecation, defecate immediately when the feces enters the rectum to produce bowel movements. For people who have habitual constipation, any urge to defecate, even if it is very weak, is valuable. Once the urge disappears, it is not so easy to have it again. If you ignore the urge and do not defecate in time, the urge will be suppressed and the stool will stay in the large intestine for too long, so that too much water will be absorbed and the stool will become dry, and as a result, the stool will not be easily discharged. The prevention and treatment of constipation has a better effect on the following fruits: pears, peaches, bananas, oranges, mandarin oranges, watermelon, melon, sugar cane, water chestnuts, etc. These fruits are generally cold, with the effect of clearing heat and moistening the intestines, can directly stimulate the intestinal tract, increase intestinal peristalsis, while containing a variety of vitamins and a large amount of fiber. Cucumber, carrots, tomatoes and the above-mentioned fruits are similar, raw food also has a good laxative effect. Apple contains tannic acid, but sometimes not conducive to the treatment of constipation. Gui He is warm in nature and can affect the bowel movement of people with high fire energy. Vegetables containing more fiber include fungus, silver fungus, shiitake mushrooms, kelp, bok choy, mullein, pumpkin, etc. Fruits containing more oil such as pecans, sesame, melon seeds, etc. have laxative effect.
