I have hypothyroidism and though I eat healthily and exercise three times a week and take medication levothyroxine 25 mg once every day I am gaining weight, I am really worried as I am working so hard keeping a diet diary. I have even gone on a specialized diet and exercise regime to no avail, I still have a lot symptoms such as exhaustion dizziness and a foggy mind . I just want to be healthy and I feel like no one is listening to what I say. Please if You can help suggest anything at all I would be most grateful.
