Rectal finger test usually does not have complications, which may be caused by irritation of the intestinal mucosa leading to an increase in the number of bowel movements, or other causes such as gastrointestinal dysfunction, colon cancer and other factors. Rectal finger test is an examination in which the doctor inserts his finger into the anus for palpation, which is simple, reliable and important for the diagnosis of rectal polyps, cancer and other diseases. Rectal fingerprinting is a non-invasive test and generally does not cause complications. During the operation, it may stimulate the surrounding tissues leading to discomfort or the feeling of urination and stool in some patients, and may also lead to an increase in the number of bowel movements, but it will not be too frequent. The cause of increased stool frequency may also be gastrointestinal dysfunction, colon cancer and other reasons. If the patient has eaten unclean food before the examination, which causes gastrointestinal dysfunction, and happens to have a rectal fingerprinting, the patient will mistakenly think that it is caused by the rectal fingerprinting. Colon cancer patients will also have increased stool frequency after rectal fingerprinting, which has nothing to do with rectal fingerprinting. If you have the symptom of increased stool frequency after rectal fingerprinting, you should go to the hospital in time to improve the relevant examination, such as colonoscopy, to clarify the cause of the disease, and treat the symptom under the guidance of the doctor.
