Hello, Thanks for the query. Please let me know when treatment was advised what was the TSH level? What do you mean by " Once last checked thyroid was 1, so doctor advised 100 mg" Because why would a doctor advise 100 mcg of thyroxine with TSH being 1 mU/L? When one has hypothyroidism (TSH has to be above 10 mU/L or there may be high Anti TPO Antibodies), then only treatment is started. With correct dosage, TSH is maintained around 3 to 4 mU/L, at which level almost all the symptoms are in check. Thanks.
