If the bowel movement is not smooth, it can be regulated by diet. Common vegetables and fruits with high fiber content can promote bowel movements. The better fruits for bowel movements are dragon fruit, kiwi, bananas and apples, all of which are foods that help with bowel movements. Bananas must be eaten with black spots on top, more ripe bananas. If it is a greener banana, this banana will produce a substance, so that the bowel discharge is not smooth. If it is a drug, there are many drugs on the market to promote bowel movements, but it is not recommended to often take drugs that promote bowel movements to prevent intestinal dependence, and even prone to colon melanosis. However, if the bowel movement is not smooth, you must first rule out the possibility of intestinal obstruction. If there is no bowel movement for more than three days, and the stomach is distended, painful and cannot be touched, in this case, you must go to the hospital for examination to see if there is intestinal obstruction. If there is really intestinal obstruction, you should not eat anything and fast from water. If there is no intestinal obstruction, and the bowel movement is simply not smooth, you can use dietary therapy or take laxative drugs.
