The one thing no one mentioned when I got a colostomy was support. I blame myself for not researching it or ever working with a patient with a colostomy. Support for the actual colostomy bag so you do not get a hernia. I did get a hernia; it isn’t that bad so they will not reduce it as it reduces when I lay down. Two options: a colostomy hernia belt, which are terrible or panties as Comfizz High Waist Ostomy Underwear for Women | Level 1 - Light Support which are great. You can get them through Amazon. I did a lot of research, and these were the favorite of many. You have support and can do away with the belt.

The best deodorizer I have found is Safe n' Simple Assure C - Clear Lubricating Ostomy Pouch Deodorant - Colostomy Bag Odor Eliminator. Also, from Amazon. I have looked to see if Byram Health Supplies has it. Forget Adapt or the other usual ones, they don’t work.
I also use the Safe n' Simple Peri-Stoma Cleanser & Adhesive Remover Wipes from Amazon or Byram.
Hope this helps.
