The treatment is a quick, nonsurgical approach administered by your doctor to improve the bulk and thickness of the anal walls. It is given through 4 nonpainful injections into the wall of the anal canal. The injections bulk up the tissue in the anal canal, providing more control of bowel movements. Since the injections are well tolerated by most patients, anesthesia is not necessary. The procedure takes about 10 minutes and can be administered in the office.
