What causes low TSH level in blood?
same dose needed
I am Dr Mittal.
I have read your query.
I think I would be able to help you.
The dose of the thyroid medicines you are taking seems to be adequate. I will not suggest changing the dose.
As for your other problems, it's possible that the loss of subcutaneous fat that is always seen in elderly is causing the symptoms.
Unfortunately, there is no good treatment for that.
I have tried to make it as simple as possible. I hope that the information helps you. Please feel free to contact us for more information. Best of luck. Dr Mittal
My tsh was 3.92 in 2012,13,14 then 1.35 in XXXXXXX of 2015. I thought levothyroxine was suppose to raise the level of the missing or lowered thyroid hormone in my body. This sounds like the levo is not doing that. Why wouldn't upping my dose raise the tsh level........I felt fine at the 3.92 level and now feel like crap. thanks
Explained the physiology
Thanks for your response
You have to understand thyroid hormones to get the answer I gave.
TSH rises when the thyroid hormones T3 and T4 are low.
It tries to make the thyroid hormones.
When thyroid hormones are available, it has not got to make anything. So it becomes low.
So it should become low.
T3 and T4 become high.
For monitoring, we use only TSH.
As for fat, it does not matter if you are on the heavier side.
The generalized coat of fat under the skin becomes reduced.
Thats what I meant by subcutaneous fat pad.
One may be very fat, but skin fat coat reduces with age.
So it causes feeling of cold as well as loss of hair, skin wrinkles etc.
As per me, your thyroid levels are good.
Continue the medicine as it is.
Best of luck.
I just noticed your specialty is diabetes and I didn't mention that I was diagnosed as diabetic type 2 just last XXXXXXX when I was having the tiredness and hair loss and my Dr found my A1c at 9 and by december of last year it had gone down to 6 and I am on 500mg ER of metformin daily. Could this affect my thyroid levels. My morning fasting levels are usually between 111 and 130 if that helps. Thanks
It's more likely that the thyroid replacement therapy is working better and thus may be related to your weight loss probably. In diabetes, there is always some weight loss. This would have reduced the need of thyroid.
However, I would not suggest that you reduce the dose of thyroid replacement therapy.
I hope that the information helps you. Please feel free to contact us for more information. Best of luck. Dr Mittal
