What if the dregs pulled out by bowel cleansing before colonoscopy have bloodshot blood?

Before colonoscopy, the red blood in the dregs may be caused by intestinal stimulation, ulcerative colitis, rectal polyps, etc., and treatment should be taken according to the cause. The details are as follows:

1. Patients with intestinal stimulation

should drink warm water properly after stopping the bowel cleansing drug, which can promote the disappearance of the drug stimulation to the gastrointestinal tract and improve the phenomenon of red blood.

2. Ulcerative colitis

If the patient has ulcerative colitis, mucus pus and blood may appear during defecation. It is necessary to use aminomethylbenzoic acid, sulfasalazine, prednisone and other drugs as prescribed.

3. Patients with rectal polyps and rectal

polyps can be treated by electrocautery resection, microsurgical resection under anus microscope, etc.
