I have a parasomal hernia. I was never told about this happening.
I understand it is quite common and mine is small by some standards I am sure.
I suspect, but I wonder how large it could get. I wear a belt every day but take it off at bedtime as gravity is less. It recesses when I have the belt on. I'm a healthy and very active 74-year-old and was operated on 4 years ago. The hernia appeared in the first year and so far has not grown too much.
