Constipation is a digestive symptom characterized by a decrease in the frequency of bowel movements, a decrease in the volume of stool and even dry, strained stools. Treatment of constipation requires a combination of medication and daily dietary regimen. The causes of constipation are divided into two categories: functional and organic. Functional constipation is related to low food intake, lack of fiber or water, and psychosomatic factors. Severe constipation is usually defined as constipation with persistent unrelieved symptoms that seriously affects life and for which treatment is ineffective. The diagnosis of constipation first requires the exclusion of organic lesions, often in combination with anoscopy and colonoscopy. If the lesion is organic, such as an occupying lesion of the intestine, surgical treatment can be used depending on the condition. For more serious functional constipation, we mainly emphasize comprehensive treatment, that is, some adjustments from diet and living habits, diet can be more dietary fiber-rich food; life pay attention to rest, ensure sleep, usually do more exercise, avoid sedentary. You can also use some drugs to assist in the treatment, such as the drugs to promote intestinal peristalsis Mosapride, etopride, osmotic laxative lactulose, etc.. The specific medication needs to be combined with the clinical situation, subject to the guidance of the doctor’s interview. In general, for severe constipation, it is necessary to come to the hospital as soon as possible, under the guidance of the doctor for regular treatment, to avoid the use of some stimulating laxatives, causing further disorders of intestinal function.
