Hey Alex, if you go hyperthyroid, it can make you lose a bunch of weight. That happened to my Mom when she was younger. It made her really irritable and eventually she had the enlarged throat and eyes that protruded a bit.
I have had my thyroid tested and everytime it comes back okay. Someone told me that there is a different test for thyroid problems, I guess more detailed? But I don’t have insurance so I can’t afford all these tests. The only time I have been able to get tested was when I got some financial assistance at my university hospital.
