I have passed out and woke up in an ambulance 3 times within 2 years. They blame it on low blood sugar but I do not believe that. I know I am going to pass out because I cannot see, I can t focus, and then I go out, completely out. I have been diagnosed with Hashimoto disease and doctors feel once my thyroid gets moving or the drugs get it moving, my blood sugar will balance out. I just don t feel good. Nauseated, not grounded, eye sight I am finding hard to focus.
