Can T3 Raise Blood Pressure?

Hi All,

My free T3 is in the lowest low end of the range = 232 (230-420). I just don't know why my doc is reluctant to add T3 to my normal regime of Levothyroxine, since I have many symptoms of hypo. He says my TSH is withing normal range, although I don't see a number for this on my last report. My T4 free is .93 (.8 - 1.8)

I do have high blood pressure, but it is treated by meds. It still can show up a little high on the readings at the doc's office.

I just wondered about the possible reasons why he is continually reluctant to treat my T3.

Re: Can T3 Raise Blood Pressure?

Having untreated hypothyroidism for a length of time will cause you to have high bloodpressure.

Your Ft4 and Ft3 are very low. What dose of levothyroxine are you taking?

Re: Can T3 Raise Blood Pressure?

Lady50 is right. My thyroid dr. told me being hypo can raise your bp. Since both your ft4 and ft3 are very low you would probably do better on Thyrolar or Armour (they both contain t3 and t4. Bring your levels up slowly to the top 1/3 of range. To balance them you may have to add a little extra (t4 only).

I didn't have high blood pressure until I had to change doctors and he cut my meds in half because my tsh was low. My ft4 & ft3 were in the top 1/3 of range and tsh was .4 and I had NO SYMPTOMS!!!!!. I was on Thyrolar and he put me on Synthroid (t4 only). Within 3 mo. I was crippled and had almost all the horrible symptoms. I have since learned that I was having withdrawal symptoms just like someone who was coming off drugs. I had taken this same medication for about 30 yrs. and all of a sudden cut in half with NO t3. If I had needed the cut back some, which I didn't, he should have done it slowly.

I would also find out what my TSH was, because what the dr. says is normal, might not be normal for you.
