What are the causes of occasional hematochezia?

Internal hemorrhoids are hemorrhoids that grow above the anal dentition line and are covered by rectal mucosa, which is controlled by autonomic nerves and does not feel painful. The early symptoms of internal hemorrhoids are mainly intermittent painless bleeding. Another possibility is rectal polyps, when rectal polyps grow to a certain extent, mucosal inflammation occurs on the surface, showing intermittent hematochezia, bleeding is generally less than internal hemorrhoids, and it is obvious intermittent bleeding. If you want to identify these two diseases, you can do rectal endoscopy to see if there is internal hemorrhoids or rectal polyps. If there are internal hemorrhoids, you can use internal hemorrhoids suppository for treatment, and insist on using it for a week. If such rectal polyps are found, it is recommended that the patient be removed directly under anesthesia, as rectal polyps carry a risk of cancer remaining in the body.
