That is one of the symptoms I am having. I gain a lot of weight even in periods where I watch every calorie and exercising which is truly frustrating. Especially since I'm overweight so I get looks from doctors that seem to imply that I'm just shoving cake into my mouth 24/7 when I claim I'm watching my weight.
You are right. There are much worse things to have and I'm happy that if I do have it that it isn't fatal. Just need to make some life adjustments.
