Anus a little bit sagging what's going on

Anal swelling may be caused by local hemorrhoids or rectal mucosa too loose. Anoscopy is needed to check whether hemorrhoids bulge at the dental line is too large. After eliminating hemorrhoids, further screening of defecography is needed to check whether there is intestinal mucosa relaxation. Mucosal ptosis oppresses the nerves of the anal opening, which also causes the patient to feel pressure and swelling.

Treatment methods are mainly surgery. Hemorrhoids are mainly treated by external dissection and internal ligation of mixed hemorrhoids. Rectal mucosal prolapse is mainly treated by circular resection and stapling of upper mucosa.
