Ostomy belt

I have no experiences with these belts. Do they make a difference? What is the best thing that you get out of wearing a belt? And also if the belt is applying pressure on the stoma how is gas and substance still able to come out of the stoma hole when it's being covered with pressure? Thank you in advance

I found a belt helpful when I had my loop ileo bc it anchors the seal. The belt doesn't apply pressure on the stoma -- if anything, it distributes the pressure from the weight of the ostomy bag around your waist or hips instead of having it pull directly on the seal. It especially helped hold up the ostomy bag while my abdomen was recovering for surgery and was super tender/sore, because I could adjust it to fit around my hips. Ask your ostomy nurse for a belt to try.
