Could birth control cause you levels to suggest you have hypothyroidism when actually you do not?

Could birth control cause you levels to suggest you have hypothyroidism when actually you do not?

No: The estrogen in birth control pills increase the levels of thyroid hormone binding proteins in the blood. This requires your thyroid to make more hormone to fill up the binding sites. If the thyroid is not working well, it will result in lower blood levels of thyroid hormone and a rise in tsh, the test used to determine hypothyroidism. A rise in TSH with birth control pills means hypothyroidism. ...Read more

Dx hypothyroid in April, been on synthroid (thyroxine) 0.025mg x 3 months, but TSH went higher (~13) w/ normal ft4. Could viorele birth control cause high TSH?

What's the next dose: Don't think so. More likely it is because 0.025mg is the smallest Synthroid (thyroxine) pill. Synthroid (thyroxine) comes in about 12 sizes, from 0.025mg to 0.300mg. If one's doctor started her on 0.025mg and there is no drop in the TSH, one can ask at her follow-up visit (there is always a lot of follow-up until the proper dose is found and the TSH is normal) what the next dose is. ...Read more

Will birth control pills damage my thyroid even more than it is? I already have hypothyroidism and taking levothyroxine.

Will birth control pills damage my thyroid even more than it is? I already have hypothyroidism and taking levothyroxine.

Birth Control: Doesn't damage your thyroid. The estrogen in the birth control pill will stimulate an increase in the amount of thyroid binding globulin (TBG) your body makes, so you may require a slightly higher dose of levothyroxine to compensate for the increased tbg. A similar phenomenon occurs during pregnancy. ...Read more
