Hi î have recently been diagnosed with hypothyroidism. My TSH was very high and my T4 very low. Futher tests showed antibodies. Initially I was put on 75mcg of levothyoxine as my pulse rate was 96. My next blood test (after 6 weeks) showed a reduction in TSH and an increase in T4. Although still not in normal range because there was improvement and pulse rate was still 96 my Endocrinologist kept me on 75mcg. After another 6 weeks my blood tests showed a slight increase in TSH so my Endocrinologist increased my levothyroxine dose to 100mcg per day. That was nearly 3 months ago. My latest blood tests showed TSH and T4 in normal range. However I am still very fatigued and the last couple of weeks have had dizzy spells on and off especially after eating. I would add that I am 55 female going through the menopause. Can you advise about my symptoms? Many thanks.
