With hyperthyroidism, hypertension is definitely more common, but this is not always the case. In acute crises of hyperthyroidism, blood pressure can also be lowered, particularly diastolic. In general, I'm pretty sure the problem here is the interaction between the various medications you are taking. The thyroid medication is largely overdosed considering that TSH value, and has been increased quite randomly over the various months. Also, I am not a fan of NP thyroid, since adjusting the dosage is difficult with that medication. Until the TSH is in range, we can't be 100% sure thyroid is not responsible. Look for an endocrinologist.
Im a 40(F), 410 and 113 pounds. I was diagnosed with hypertension in 2018, its been u fee control with Lisinopril HCTZ 20-12.5 with no issues. I was diagnosed with ADHD in December 2019 and put on methylphenidate 20 mg(2 in the morning and 1 at 1:00 pm). I always checked my blood pressure around lunch to make sure it was t too high, I never had an issue. I was diagnosed with Hashimotos last October and started seeing a functional medicine doctor last December. I was put on NP Thyroid 30 mg, moved up to 60, then doubled to 120 by June. I have had labs drawn every 3 months since December. I felt really good until around the beginning of August. My TSH was <.02 but T3 and T4 were in range so she reduced my medication to 105 mg a day.Since I was checking my BP for it being to high, I didnt realize it was going down. I happened to miss my afternoon dose of the methylphenidate and my nephrologist commented is was a little low. This was the last week of August. I had some scans done by my cardiologist the next week. I mentioned my fatigue and she suggested I stop the methylphenidate for a few days to see if that helped and to follow up with her in 2 weeks. The next few days my BP just completely went down, I ended up in the ER twice because of it. The did CT scans the first time I went and I had kidney stones. The second time I went, they though it was a kidney infection. I went back in the methylphenidate because it kept my BP up. I followed up with my cardiologist. She said everything was fine cardiology wise and to continue to take the methylphenidate without the lisinopril until I could find out the cause for the drop.At this point a reached out to my thyroid doctor to see if anything thyroid related could cause this and she said no because usually signs of over medication is high blood pressure. She said to let her know what the urologist and nephrologist said.I made an appointment with my urologist and he did a cystoscopy and ureteroscopy based off the CT from the ER visit but he found nothing wrong and no stones. The nephrologist also found nothing wrong.So last Wednesday, I finally get her to run my TSH, Free T3 and Free T4. I got the results back yesterday. My T4 is in range. TSH is <.01. T3 is 5.3. I ask about T3 thyrotoxicosis and again she says that would cause high BP. She wants me to not take my thyroid meds for 2 days then go down to 90 mg.This has been going on for 2 months. The constant up and down with my BP has me struggling. My vision is getting blurry. Im exhausted. Do I wait it out to see if what she says or should I go to the ER?
