I am an 18 year old female. My whole life I've been very active and I exercise for atleast an hour daily (excersize guru) but I can't lose weight (I stay around 150) and I am always exhausted- always. I need naps and a full night of sleep and I am still tired. Doctors always point out a thickness of my neck, regardless of why I am seeing them, which has led me to get labs every time, all coming up with normal TSH levels. Recently I got an ultrasound on my neck which showed multiple cysts, indicating that hypothyroidism is inevitable for me, and my doctor said that nothing has triggered it yet, but it will. I trust my doctor, because she is the expert, but I see ALL of the symptoms now, and they are very impacting on my life; making me anxious to get diagnosed and treated. I also crave sweets every moment of my life and I know it's not normal. So could I actually have a problem that's not being diagnosed correctly, or should I wait until a tsh level comes back not normal to do anything about it?
