Functional constipation: it can be promoted by drinking more water, increasing the intake of food rich in dietary fiber such as corn and vegetables, and proper exercise; if the lifestyle intervention is ineffective, it can be treated with drugs such as polyethylene glycol and lactulose. 2. Organic constipation: Tumors, intestinal obstruction and other diseases can also cause constipation. Intestinal obstruction requires fasting, gastrointestinal decompression, fluid replacement therapy, and surgical treatment when accompanied with strangulated intestinal obstruction.
