Patients with colitis are prone to a feeling of urgency and heaviness in the anal area, which leads to a feeling of bowel movement. When there is a falling sensation in the anal area, it is mostly considered to be related to enteritis, which is also accompanied by bloating, diarrhea, abdominal, pain, acute and severe symptoms, etc. The emergence of enteritis is mainly caused by unclean diet, misuse of antibiotics, mental stress or low immunity. Eating food that has been contaminated by bacteria or viruses can induce patients to develop enteritis. In addition to diet, the development of enteritis can also be induced by mental factors or the abuse of antibiotics. Improper use of antibiotics will directly stimulate the human intestinal tract, resulting in intestinal flora imbalance caused by enteritis. Patients are prone to diarrhea, abdominal pain, as well as a feeling of heaviness, which can easily lead to a feeling of stool in the anus, which is actually caused by inflammatory stimulation in the intestinal tract.
