I have had the same problem. I put on 40+ pounds in about two months after I got Covid back in early March 2020. I was not eating much, as I was feeling so bad, so I was very confused by the extreme amount of weight I gained.

I have a lot of Long Covid issues but this is the one that is the most depressing. I have worked with a nutritionist for over a year as well as with two different doctors. Nothing is helping.

I did some mitochondrial testing and got some “extremely low” results in a few areas. We’re not sure if it’s related or not.

I’m in a support group for Long Covid people who got sick in March - April 2020 - well before Long Covid was being discussed. There are many, many threads/posts about this very issue. Sadly, no one seems to have a solution or been able to take off the weight that I’ve heard of. It’s interesting that in the same group there is also a group of people with the opposite problem- they lost a tremendous amount of weight and can’t seem to put it back on. They are also alarmed and frustrated.

I can’t even bring myself to get back on the scale, as it’s too depressing. I had to get all new clothes and give away most of my old clothes since nothing fit. It’s been almost three years since this happened. I fear I will never be able to rid myself of these extra pounds.
