If there is no bowel movement for several days, it may be habitual constipation, which is caused by irregular diet, eating poorly digested food, fried and greasy food, resulting in poor digestive function. If constipation occurs frequently, you need to exclude the presence of intestinal inflammation, intestinal tumors, etc. If there is no bowel movement, you can first give symptomatic treatment with drugs, such as Bifidobacterium Typhimurium capsules, Gastroparesis pellets, Intestinal inflammation, and polyethylene glycol electrolyte dispersion. If you do not see any relief from medication, it is better to improve the diagnosis by colonoscopy and other examinations to exclude enteritis and intestinal occupancy. If there is no feeling of bowel movement, most of them are due to poor digestive function. It is necessary to increase activity, pay attention to the combination of work and rest, exercise, improve living habits and pay attention to improving intestinal dynamics. Prevent overexertion, stress, frequent insomnia, and excessive worry.
