Hi, I am Smitha from Bangalore. I have been diagnosed with hypothyroidism since August 2010. I have been taking Thyronorm 25 mcg since that time. In between last year January 2012 I just stopped taking the medication, but came to know that it has to be taken permanently. At that time, I was undergoing IVF treatment, which also was not successful. The doctor who treated me told me to increase the dose to 50 mcg because my TSH value had increased. The treatment was in June 2012. In July 2012, I started losing weight, had body pain, hair loss. I checked my thyroid. It had gone to hyperthyroidism with value of 1.0. I started taking my usual dosage of 25 mcg without skipping even for a single day and when I checked in April 2013, the value was 5.3, which was borderline with symptoms. At that time my weight was 55 kg. I did not do the thyroid test for quite long time. This year April end, I started taking ayurvedic medicine, but it did not suit me. I lost weight. I had consulted again another IVF specialist in Bangalore who told me to take 37.5 mcg, which I am taking, but still my health is going down with losing weight and hair loss. Can you tell me how much dosage should i take?
