I would like to ask about a thyroid problem, I have been told that my t4 levels are raised, I believe this to be overactive thyroid? But I do not think it has been raised for long as I have had my thyroid checked regularly. I was wondering when I may get symptoms as I have not noticed anything, I was particularly wondering about weight loss? Would I have had to have it a long time before I start losing weight? I hope this is clear and thanku for any answers.
