My antibodies were 1618 (0 - 100) on diagnosis. My TSH was 8 and now four months later it is 0.5 (0.3 - 4.5). My FT4 is at the top of the range and I feel pretty much OK on my low dose of 50 mcgs of levo. My question relates to what happens next with the antibodies. Do I take it that they will continue to attack and eventually destroy my thyroid completely therefore necessitating increased doses of levo as time goes by, or can the attack stop and therefore the thyroid remains in its present state without further deterioration. Many thanks for your thoughts.
