“Constipation is not a disease, can not be solved really dead”. For modern people, it seems to be more and more difficult to keep the intestines open every day. According to statistics, nearly 20% of the elderly over the age of 60 in China suffer from constipation. Why is constipation so common? What exactly is missing? What should be done to prevent and control it? Why is constipation and what is missing? There are many causes of constipation, such as failure to develop the habit of regular bowel movements and frequent suppression of bowel movements. Long-term mental depression, stress or excessive excitement. Taking certain drugs that can cause constipation, such as anti-diarrheal drugs, anti-hypertensives, anticholinergics, diuretics, anti-allergic drugs, calcium, iron, etc. Suffering from certain diseases that can cause constipation, such as perianal disease, colon disease, neurological disorders, and endocrine diseases can lead to constipation. In addition to these reasons the author summarized the five shortages: a lack of water, two lack of oil, three lack of slag, four lack of bacteria, five lack of power. First, lack of water: water is the source of life, the human body if the lack of water, the stool contains less water, the stool is very dry and hard, dry stool will cause constipation. Second, lack of oil: grease in the intestinal tract plays the role of lubricant, diet if the lack of appropriate grease, it will make the stool appears dry, thus enhancing its movement in the intestinal tract friction, over time, it will be dry and form constipation. Third, the lack of slag: lack of slag is the lack of dietary fiber, which is very important, dietary fiber, including soluble dietary fiber and non-soluble dietary fiber. Among them, soluble dietary fiber like a sponge can absorb water expansion, so that the stool to maintain a certain amount of water and volume, lubricate the stool, while non-soluble dietary fiber can be like a “broom-like”, promote the gastrointestinal tract peristalsis, facilitate the advancement and discharge of stool. Fourth, lack of bacteria: intestinal flora plays a key role in human health, affecting various physiological activities of the host, including gastrointestinal dynamics. The change of intestinal flora in patients with chronic constipation is mainly the relative decrease of anaerobic bacteria (Lactobacillus, Bifidobacterium, Bacteroides, etc.), and the increase of potentially pathogenic microorganisms accompanying them. Changes in the intestinal flora play an important role in the pathogenesis of chronic constipation. Fifth, the lack of power: gastrointestinal tract power is insufficient, either no strength to transport food residues to the rectum, stagnant in the colon, or to the rectum but no strength to pull out the feces, so constipation. How should constipation be prevented and treated? First, replenish water to loosen up the stool in the intestine. When the water content in the stool decreases, the stool becomes very dry and hard. Therefore, the gastrointestinal “steel” like crude fiber, but also need to have a “coagulation” effect of water, so as to help the stool is soft and normal defecation. Make sure to drink 1500-2000 ml of water every day, drink a glass of warm water after waking up, before three meals can drink warm water or soup. But be careful not to drink water during the meal, and should not drink water immediately after the meal. Second, supplemental fats and oils to lubricate the gastrointestinal motility. Oil is the intestinal lubricant, if the diet lacks the appropriate oil, it will be dry stool to form constipation. Especially female friends, because of the love of beauty often afraid to grow fat and refuse to eat fatty foods, when there is no fat in the stool, it is easy than men are more prone to constipation. Therefore, it is imperative to properly replenish fats and oils, and it is recommended to drink some fatty soups in your diet, such as pork ribs soup and pig’s upper foot soup. Third, supplement crude fiber, so that the volume of feces swell up. Crude fiber-rich foods can make the stool swell and increase in volume, facilitating the discharge of feces. Fiber-rich foods top oatmeal, bran (cookies, bread containing bran), corn. Can also eat more sweet potatoes, konjac, celery, spinach, bok choy, garlic moss (seedlings), fungus, mushroom vegetables; kiwi, red dates, bananas and honey can also be used. As for the amount of fiber, depending on the degree of constipation, generally can achieve laxative effect. Therefore, to eat more coarse grains, mixed grains, less fine rice and noodles, and with the celery bean curd, vinegar cooking bean sprouts, mushrooms and greens, shrimp spinach and other crude fiber dishes. Fourth, supplement probiotics, so that the intestinal flora balance up. All kinds of constipation patients intestinal tract exist probiotic bacteria reduced, harmful bacteria increased dysbiosis, can add probiotic preparations such as Bacillus licheniformis (whole intestine), Bifidobacterium, Pepcid, etc., beneficial and harmless. There are many lactic acid bacteria fermentation products on the market, yogurt is a good one. Five, regular exercise, so that the gastrointestinal movement. Defecation requires not only a certain strength of intestinal peristalsis, but also the cooperation of defecation muscle groups. Walking, walking, jogging, cycling and other sports, not only can improve the intra-abdominal pressure, improve the tension of the defecation muscle group, but also can benefit the longitudinal muscles of the gastrointestinal tract and circular muscles. Insist on doing sit-ups, abdominal deep breathing, practicing internal health work, strong work, abdominal massage and practice anal action, can effectively prevent the occurrence of constipation. Sixth, adjust the biological clock, regular bowel movements. Defecation should be regular, like an alarm clock, once the time colon peristalsis on its own, defecation naturally much less effort. As for the time clock defecation is not important, the key is to adhere to the regular training, to develop a good habit. It should be reminded that if the “fixed clock” has not yet been adjusted, the emergence of bowel movements must be resolved quickly, intentionally hold the stool will instead aggravate constipation. In addition, when relieving the bowels to concentrate, do not read the newspaper, play with the phone, to ensure that the colon peristalsis is not disturbed. Of course, the treatment of constipation is a systematic project, in addition to pay attention to the above six points, usually have to maintain a good psychological state, the disease to go to the hospital in a timely manner.
