A sitz bath is a form of a topical therapy for treating dilated painful hemorrhoids. A patient with hemorrhoids sits in 2-3 inches of warm water (usually in a bathtub) for 10 to 15 minutes, 2-3 times a day. The warm, gentle water enhances circulation in the hemorrhoidal veins and causes the rectal muscles to relax so that these dilated, sometimes even protruding, veins can recede back into the rectal canal. A sitz bath can also help to minimize pain from dilated and protruding hemorrhoids. Don’t add bubble bath or anything else to the water for a sitz bath.
