Blood test results... Advice please if possible ..

Hi All,

I had a blood test last friday because I have been having some symptoms and my doctor wanted to rule out my thyroid as a cause. I have an under active thyroid and I am currently on 125mcg of Levothyroxine a day. My results are:

TSH 0.006 (0.38-5.33)

Free T4 13.6 (7.0-16.0)

Free T3 5.9 (3.8-6.0)

The symptoms I’ve been having are loose bowels, increased need to pass water, oilier skin than usual and some hair loss. I’ve also recently started experiencing headaches a few hours after I take my Levothyroxine in the morning then wearing off later in the day.

Could any of these be related to my results?

Thanks Sarah 🙂

Your Ft3 is just at the top of the range. This is maybe too high for you. You could lower your levo alternating 125 and 100 to see if that helps.

Exactly what Lala says, I had also frequent urination, oilier skin, headache and other issues with high and over range t3.

Oh really? How high was your free t3?

in reply toSarahlouise1980

It was high in range over 70% and more , it's individual, some people can take more and be over range I'm not one of those

Thanks Cuppaofcha, did things like the oily skin clear up when you reduced your dose?

in reply toSarahlouise1980

They did, not immediately, but down the line. It was so bad I had see a dermatologist, he said no way that will go without antibiotics. Well, it did, but it took a few months. Mind you, I had a really big overdose for a long time

But was your free t3 still in range or over the top? My free t3 is right at the top.

in reply toSarahlouise1980

I feel like that with t3 too of the range and over range. My bloods were in the range

Ahh okay so your free t3 wasn’t even over range and you still had all the same symptoms?? Sorry for asking lots of questions I’m just trying to work out if it could be the t3 causing my symptoms xx

in reply toSarahlouise1980

Everyone is different you see, it depends when you take your dose, when you test, on your ft4 sometimes too etc. People were telling me to take more including my doctor and in the end I had to reduce, that was years ago. I guess the question to ask is - can you be undermedicated with these results? Probably not. Could it be any other illness, possibly. But! Sometimes lowering t4 by a smidge can give you a quick answer , like 12.5 mcg.

I know when I see my doctor tomorrow she will want me to reduce my dose. I think I’m going to try reducing by 12.5mcg see if I can get my t3 down a bit. If I feel worse I can always increase it back up. I definitely don’t think I’m under medicated!

in reply toSarahlouise1980

I think it's a good idea, let us know you get on. But don't reduce too much, endos tend to ask to reduce by big amounts and then we can swing from one to another

Any change in your brand of Levo?

Any new supplements started or brand change?

No new supplements or brand change in Levothyroxine. I have changed my contraceptive pill a few months ago but my doctor didn’t think that would cause the bowel/water issues x

Also forgot to mention whilst I was off the contraceptive pill over the summer my periods were very light. Almost non existent. My t3 level has never been as high as it is now it usually stays around 4.9-5. I think 5.1 is the highest it’s ever been before recently.

Not what you're looking for?
