Suzi has hypothyroidism and high blood pressure. She sends the following story describing how t3 treatment appeared to help normalize her blood pressure. This is the first time I have come across this effect and thought it would be helpful to share her story on the main blog. Does anyone else have a similar (or contradictory) experience?
Hi Dr. Pepper,
I was diagnosed hypothyroid 2 years ago and given levothyroxine. On diagnosis I had lots of symptoms and my BP was 175/115 despite my whole family having low BP. After some months on T4 I did feel an improvement in a lot of ways and my BP got better. Then after a year, things started going wrong, as if my body didnâ€™t like T4.
I tried reducing my dose of T4 back down to 75Âµg but went hypo. But each time I increased above 75Âµg my BP increased again, then on 112Âµg it became a serious problem, especially the diastolic. I still had fatigue, constipation, red eyes, swollen legs and so on.
About 3 weeks ago I started on 10Âµg T3 and reduced my T4 from 112 to 75Âµg and pretty much immediately felt clearer headed and more energy, the constipation went etcâ€¦.. My BP has gone down by an average of 20, which I know because I check it regularly myself. Iâ€™m doing a 24-hour BP monitor this week too, because my doctor put me on Amlopidine 6 weeks ago after being shocked by the monitor results from then while on 112Âµg T4 (only took Amlopidine for 2 weeks after terrible side-effects incl. overwhelming fatigue and massively swollen legs).
So, it looks as though my body goes weird on T4 tablets when the dose is above 75Âµg, but if I stuck to that dose Iâ€™d be really hypothyroid. The T3 has changed my life completely!!
Now Iâ€™m wondering what the ideal balance T4 / T3 tablets would be? Is that possible to say or does it depend on each individual body and genetics? My typical BP now is around 120/ 95; it goes down after eating, and gets worse when Iâ€™m hungry or tired. The T3 reduced my BP so much more than the Amlopidine did, and on T3 I feel great whereas on Amlopidine I felt half dead. Iâ€™d like to get my BP back to before I got hypo, so thatâ€™d be 110/70.
All I need to do now is find my ideal dose of T4 and T3, could you possibly advise me on that? If I started 20Âµg T3 instead of 10Âµg, would you advise a reduction in T4 from 75Âµg? ( Iâ€™ll be doing a TSH, fT3 and fT4 test in about 5 weeksâ€™ time, maybe I should wait till then?).
Thank you so much!
