Hello and welcome. I'm Dr Chip

Can you more fully tell me the problem here?

Customer: replied 8 months ago.
Hello Dr Chip - I am unclear on whether or not I am on the right dose of synthroid for my elevated TSH level of 8.5 - I am actually finding that I am very bloated and gaining some weight. Do you know what the correct dose would be for that level?
Expert:  tazechip replied 8 months ago.

Thanks--what dose are you on now and how long have you been on it?

Customer: replied 8 months ago.
I am on 112 mcg - and I Have been on it for about 1 month
Expert:  tazechip replied 8 months ago.

Sorry for all the questions but were you just started on the levothyroxine a month ago and if so when was that TSH level taken?

Customer: replied 8 months ago.
I was started at that dose and that is when they had detected it was around 8.5 -
Expert:  tazechip replied 8 months ago.


I personally would have started you at 125 mcg but 112 is still reasonable as a start.

It takes at least two months for a given dosage to lower the TSH so I would recheck you in another month

The goal would be to get your TSH level below 2.0 so if it isn't there in another month, I'd increase your dose to the 125 mcg

This is often what we do in medicine--it's called titration--try something, check its results after a while, and then increase or decrease the dosage according to the TSH level

You really haven't been on your present dosage long enough to see the final effect so you need to wait another month

Please let me know if you need any more information

Ok. Do you think my dose could be causing this bloating and weight gain?Is my TSH very high? Meaning the 8.5 level. I should add that I had a baby in May and only after that did I have elevated TSH.I was thinking I would be LESS bloated and LOSE weight.
Expert:  tazechip replied 8 months ago.

No--that's from your hypothyroidism not yet fully treated.

Normal TSH is up to 4.0 so yours is moderately high, indicating not enough thyroid hormone.

As I said it will take some time and after another month your dosage may have to be increased
