The constant urge to defecate may be caused by proctitis or dysentery, or it may be related to hemorrhoids or rectal tumors. Bacterial infection that invades the rectum can cause anal edema and stimulate the nerves to want to defecate. In addition toxins in pus, blood and feces stimulate the anal nerve and can also cause the urge to defecate. You can go to the hospital for a colonoscopy and routine stool examination to determine if the infection is present. It can be treated with drugs such as norfloxacin, and hemorrhoids and tumors can be surgically removed. If it is chronic ulcerative proctitis, for inflammation occurring in the rectum, generally enteritis has three symptoms: congestion, edema, erosive ulcers and bleeding ulcers, so it can cause the anus to have bowel movements all the time. You should go to the hospital to perfect the examination and eliminate the possibility of rectal cancer. If the symptoms are not serious, then you can take probiotics orally to regulate the intestinal problems, or you can take oral Chinese medicine and proprietary Chinese medicine to regulate the body. It is recommended to eat a light diet, pay attention to rest, and eat less or no spicy and stimulating food as much as possible.
