I have had a eurostoma for 10 years. Within the first year I developed a hernia, much to my surprise. I went to see my surgery Doctor for the last time. I showed it to him and asked about it. His response was kind of crass. He said you will be ok, just don't get fat. I will never get fat, I weigh the same as I did 50+ years ago. (I'm 80 years old this year and still weigh the same 173 pounds.)
So I was on my own, seeing as I had no ostomy nurse or Doctor left to advise me. Google comes to the rescue. Research tells me three things. 1) It will slowly get bigger over the years. (I'm 9 years into it). 2) The mesh insertion repair is only about 50% sucessful. 3) Belts don't appear to do much, unless you are going to play football or any contact sports where you need protection. A company in NY sells one that is made of hard plastic and works like a hockey cup.
So over the years I have purchased quit a number of various types of belts, which I do not where on a regular basis. I do like the secure feeling I do wear my 5” wide one. I also have a 3” one but prefer the wider one.
When putting it on, be sure to raise the area on your back as high as you possibly can to give more “lift” on the hernia, that is important. If you don't it is just pressing on your hernia and gravity is still pulling it down, which defeats the purpose in my opinion.
My hernia is now about the size of a very large grapefruit, but I can easily live with it at there is no pain.
