Is there some people here that know a friend/family member or anyone that trains/workout or do any sports and has a Stoma?

Should ask your doctor tbh

cant you get that closed up?

Yeah you can after a certain amount of time...If you decide too... but there is some backfire and most of people keeps the bag.

and for the ask a doc...I'm looking for tricks or things that people got used to to do sports/working out etc.

its really specific to your condition, where is the stoma?

might want to avoid certain exercises

On the left close to belly button.

All tho I bought some adapted cloth and a driving belt so its more comfy when I drive etc..
lost of stuff will be bought to protect it and make it less visible.
