Hi, I am new here and this is my first post. My 14 year old daughter has just received her blood results. Her TSH is 11, and her T4 is 11. She started menstruation at 11 years of age, but has only had about 2 periods a year, and they have always been extremely light. We went for tests because she had fatigue, puffy eyes and joint pains for 10 days now. Our GP is away, and I'm anxious for a little light on her case of hypothyroidism - all advice and information will be appreciated.
