Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: Thank you. I was taking Jaimiess birth control until mid-July. The functional medicine doctor kept suggesting I get off of it to help get my hormone levels up since I was only on it to lighten my periods. From what I read, the estrogen acts as an inhibitor for the thyroid medicine, which would explain why the dosage needed to be increased so much before it started working. Then I went off the birth control and the thyroid meds just went wild. I asked her if that could possibly be a factor but she said no. I am now also wondering if my hypertension was caused by the birth control. Hypertension runs in my family so I just assumed that was the reason. I had no idea birth control could cause that. Im looking for an endocrinologist but the 6 Ive called, with good reviews, are at least 3 months out. Im debating if I should go back on the pill so I can get my BP back up for now, then come off of it under the supervision of an endocrinologist. My cardiologist said, shed rather it be high(obviously not too high) that can brought down with meds, than it be too low. I just know I cannot continue with the methylphenidate like I have. Again, thank you for your response.. ### Response: Estrogen has an effect on thyroid function by altering the hormone-binding protein, but generally the problem is when you stop therapy or go through menopause. It is also true that the pill can increase blood pressure, but not so much that you go from hypertension to hypotension. The effect of the pill is modest. I think if therapies are the culprits, it depends more on the triad thyroid hormone-antihypertensive - ADHD meds . I don't think it's a good idea to start hormone therapy again just to control blood pressure, honestly..
