Daily diarrhea means daily diarrhea and may be suffering from irritable bowel syndrome, ulcerative colitis, Crohn’s disease, etc. The details are as follows: 1. Irritable bowel syndrome: this disease is often accompanied by abdominal pain, except that all tests are negative. The etiology of the disease is related to psychiatric factors, and if there has been a lot of stress recently, it may lead to overreactivity of the intestines and produce recurrent diarrhea. 2. Ulcerative colitis: The etiology of this disease is complex and is related to the environment, genetics, and the microenvironment of the intestines. These factors ultimately lead to an immune imbalance in the intestinal tract, destroying the intestinal mucosa and eventually leading to recurrent diarrhea, which can also be combined with mucopurulent blood stools. 3. Crohn’s disease: the cause of this disease is the same as ulcerative colitis, which destroys the entire digestive tract from the mouth to the anus, and the lesions will be thickened and ulcerated, which ultimately leads to daily diarrhea. Daily diarrhea may cause dehydration of the body and should be taken seriously. It is recommended to go to the hospital in time, to clarify the cause of the disease, and standardize the treatment under the guidance of the doctor, so as not to delay the condition.
