”Doctor, my stool has become thin recently, help me see if I have hemorrhoids” “Doctor, I have trouble passing stool, I think the hemorrhoids are getting bigger and bigger and blocking my anus” “Doctor, is it true that if you have hemorrhoid surgery, your stool will become thicker? ” Is that so? Because having hemorrhoids makes your stool thinner? Not exactly Let’s talk about the causes below! Hemorrhoid disease causes Hemorrhoids are caused by varicose veins and fibrous tissue growth in the mucosa of the anal canal and lower rectum. In particular, internal hemorrhoids, patients have protrusions or circular protrusions in the anus, the protrusions occupy the area of the anal canal, and the stool passed thereby is compressed and thinned, often with fresh blood on the surface of the beginning section and the end. Anal foreign body causes Among them, hemorrhoids, internal hemorrhoids, external hemorrhoids, mixed hemorrhoids, anal fistula, perianal abscess and other anal diseases bring obvious discomfort of anal foreign body to the patient. In case of anal foreign body, the foreign body blocks the anus and the patient has difficulty in defecation, or the stool becomes thinner and smaller due to the pressure of the foreign body, causing abnormal stool. If the anal papilla is enlarged, it is one of the common benign tumors of the anorectum, which is enlarged and hardened by the long-term stimulation of feces and chronic inflammation. If the anal papilla is enlarged into a tumor, it will block the anus, and the patient will have difficulty in defecation or the stool will become thin and incomplete due to the pressure. Anal rectal tumor Pre-cancerous bowel manifestations, patients have more frequent stools, unformed or thin stools, stools with blood and mucus. Sometimes constipation or alternating diarrhea and constipation, thinning of stool. Abdominal pain, the degree of which varies, is mostly vague or distending. In case of tumor necrosis or secondary infection, patients often have fever. Of course, one-fourth of the stool is water, and the rest has protein, inorganic material, fat, undigested food fiber, digestive fluid residue, and epithelial cells shed from the intestine, mucosal debris and dead bacteria. If there is not enough fiber in the poop, the volume of the poop is not large enough, there is no gravity, and it does not hold the anal opening open hard enough when it reaches the anal exit, it is certain that the poop that eventually comes out will not be in such a desirable condition and will be finer. The actual fact is that you can find out that the poop has been thin for some time, you must integrate other bodily changes and get a consultation with a specialist to check it out, not simply because of hemorrhoids.
