The characteristic of chronic constipation is that the rectum is stimulated to a certain extent, causing the brain to reflect the feeling of defecation. First, proctitis or prolapse of the rectal mucosa, which can appear to have some secretions or severe congestion and edema in the rectum, resulting in the feeling of having stool, but not too much stool. Second, hemorrhoids, many patients with internal hemorrhoids are prone to some perianal, anal and dentate line stimulation caused by hemorrhoids, causing the feeling of defecation. Thirdly, the feeling of wanting to defecate can also occur as a result of plant nerve dysfunction caused by fatigue and exertion, which leads to irritable bowel syndrome. If you always want to have a bowel movement, but you do not have much bowel movement or you have a heavy lining, you need to pay attention to diet, rest, and medication. Clinically, Bifidobacterium capsules, 2 capsules once, 2 times a day or Glutathione tablets, 2 tablets once, 2 times a day are commonly used. If there is no relief repeatedly, it is better to improve the colonoscopy to further confirm the diagnosis.
