Laxatives are drugs that increase water in the intestine, promote peristalsis, soften stool or lubricate the intestine to facilitate defecation. They are mainly used clinically for functional constipation. Many patients with constipation, the first thought is to take laxatives when defecation difficulties, but often take laxatives are harmful, let me take you to understand the hazards of often take laxatives. Hazard one: because many laxatives may damage the intestinal wall plexus cells, causing further constipation, long-term use can cause intestinal wall blackening, and even induce intestinal tumors. Hazard 2: The repeated stimulation of the intestinal tract by laxatives can cause gastrointestinal dysfunction. If laxatives are applied too often, it will cause drug dependence, and the smooth muscle of the large intestine will atrophy and cannot move on its own. Hazard 3: Long-term use of laxatives may cause water and electrolyte loss from the intestine, resulting in dehydration, electrolyte imbalance, softening of bones, and vitamin and mineral deficiencies. Hazard 4: The use of laxatives also affects the absorption of nutrients in the intestine, leading to malnutrition, which in turn causes thinness, sickness, anemia and other symptoms. Hazard 5: Long-term use of laxatives only temporarily relieves the symptoms, rather than adjusting to restore the normal bowel function, and over time forms a habit and dependence on laxatives, resulting in diarrhea if you take them, and constipation if you do not. Due to the frequent use of laxatives, because the stimulating effect of laxatives on the intestinal tract gradually weakened, many patients can only be effective by constantly increasing the amount of laxatives. Hazard 6: Commonly used laxatives such as rhubarb, he shou wu, senna, cassia, etc. contain enquinones, long-term use will cause accumulation of poisoning, jaundice. Improve bowel movements, refuse laxatives 1, a reasonable mix of meals, appropriate to eat more coarse grains, fruits and vegetables. Leeks, celery, cabbage, carrots, fungus, etc. are rich in dietary fiber, which can promote intestinal peristalsis. You can also drink yogurt appropriately. 2.Drink 1500~2000ml per day. A bottle of mineral water is about 500 ml, constipated people should drink 3 to 4 bottles a day, once a half bottle, a large amount of water than each time a small amount of drink, multiple times to drink the effect is better. However, those with a bad heart should not drink water too cold or too Mongolian, it is recommended to consult a doctor. It should be noted that here is said to drink water, can not be replaced by coffee, strong tea and drinks with too much sugar. 3.Appropriate exercise and relaxation. Constipated people are recommended to often do anal lifting exercises, contraction and stretching of the anus, exercise the anal muscles. 4.Regulate emotions and have a positive attitude.
