There are many reasons for anal discomfort and always feel that there is a stool, the common ones are as follows: the first one is that if the patient takes food that is not easily digested, some food residues are easily stored in the rectum, which can lead to a foreign body feeling at the anal opening, giving bowel cleansing treatment to smoothly discharge these foreign bodies and stools, the symptoms will gradually disappear. Secondly, if the patient had mixed hemorrhoids in the past, long-term oral consumption of a lot of stimulating food such as mustard, chili, etc., will easily cause the hemorrhoid nucleus to accumulate and swell, which will cause the anal opening to have a feeling of anal swelling and discomfort, and sometimes the hemorrhoid vein bleeding out of the anus will also form a thrombus, which will cause a painful sensation. This situation should be actively treated with medication and, if necessary, surgery. Thirdly, if the patient has long-term outlet obstruction type constipation, such as anterior rectal protrusion, endorectal overlap, it will lead to obstruction of fecal discharge at the anal opening, and feces stored in the lower part of the rectum will easily form fecal stones after water absorption, which will also lead to a foreign body sensation in the anorectum, and sometimes there are stools and unclean bowel movements. In this case, you need to perform a rectal examination and, if necessary, a fecal imaging to clarify the diagnosis.
