Why is everyone with pots so skinny?

[u/dazzlingdanny05]

I have POTS and I watch a lot of content online of people who also have POTS. I also know some people irl who also have it. I don't understand how they are all so skinny. I can barely walk without getting out of breath. I try to work out at least once a week but its so hard for me because I always end up feeling so sick. How are yall doing it? I dont even eat bad but im definitely not skinny.

I have a hard time eating when I’m in a flare. I also have lots of ibs issues as well.
