One of the worst things that would end up happening after you start living with an abdominal stoma and a colostomy bag at this current point in time is that you would no longer be capable of remaining as active as you used to. As a result of the fact that this is the case, you might start to suffer from some serious mental health symptoms as well as gaining a bit of weight which would put other aspects of your health at risk along with making you no longer like your physical appearance all that much.
It is important to stay active when you are living with an ostomy bag, and doctors would tell you this as well based on their own experiences. How then is someone supposed to balance their decreased mobility with the need for exercise? Well, an ostomy support belt maintain adequate cover after coloctomy, and this can facilitate a much easier exercising experience without a shadow of a doubt. For starters this is the kind of thing that keep the bag in place rather than have it jostle around every time you move.
This jostling is what makes exercise impossible, so if you can find a way to control it going for a run will no longer be all that much of an issue for you. Running is the best possible kind of exercise that you can take part in after all, so you might want to consider doing it a few times a week with your support belt. Keep the support belt tight during the run otherwise your ostomy bag might come loose and start to leak which would create a rather huge mess.
