well I’m not sure . I don’t know how it happened actually. I got sick a couple of years ago . I’d gone on the keto diet and lost weight the first month but then gained it all back after . My dr said keto was really not a good healthy diet . Then got sick in 2020 ended up getting pots after but didn’t know for a long time what was wrong with me . Then my dr misdiagnosed me and gave me a high dose of prednisone which then got massive sick again and after loads of ER visits and cardiologist testing they just said it was not my heart but anxiety. I knew someone was wrong. I used to be a nurse . So I started researching. My hypothyroid went into hyper mode that’s what the Hashimoto can do . But been losing so much weight due to everything probably changed a lot of hormones around. The dr doesn’t understand it only said thyroid gland still working so taking off the meds . But it can go back at anytime. So just have to keep monitoring it . I’m still trying to figure out how to lower my TPO antibodies numbers . They were last only at 179 and that’s high but not as bad as a lot of people.
