also if you are losing too much weight (some loss will happen) then your doctor needs to change your dosage or try a new medicine for you.
is it possible for a therapeutic overdose of synthroid to cause weightloss? . i have been on synthroid/levothyroxine for years. over the past year i lost (on purpose) 45 pounds. now i cannot maintain my weight. i have increased my calories by half and still am losing weight. could this be because my synthroid dose is no longer appropriate for my weight?
