Hormonal weight gain/thyroid
So basically I have had thyroid issues my entire life. I have always been skinny, weighing like 100-120lbs. I got pregnant young ( miscarried ) and then started to gain a bunch of weight after that.. then 8 years later I had my daughter in 2023, I lost all my weight and for a year was around 120lbs, then it all started to slowly come back. My thyroid doctor has said that my levels are fine, but I just feel like there’s something missing. How do I spend my whole life being skinny, getting pregnant and then it messes everything up?
I am a very active person, I walk 10-20k steps a day, drink water, gatorlyte, have horses, etc.
Please help with recommendations. I’m at a total loss and I just feel like there’s something going on that’s being missed.
