Question: My FT4 is 0.9ng/dl and my TSH = 1.72 mUI/L. I am 48 weigh 75 kilos and 170cms. I am always tired and can sleep for hours, i have had half my thyroid removed in 2007 and do not medicate. I have extremely heavy periods, suffer from anxiety a bit of depression and frequent constipation. I have gained 15 kilos since i turned 40 of which at least 10 since my thyroid op in 2007. Is it possible my thyroid could be underactive?

Brief Answer:
Looks like prozac side effects

Detailed Answer:

I have read your query
The normal levels of FT4- 1.0 -4.3 U
The normal levels of TSH- 0.3 - 5.0 U/mL
So by this I dont think that there is the issue of inactive hypothyroidism.
Yes FT4 is just outside the normal range, but that may be a lab variant
Besides, if it was hypothyroidism, the TSH levels would be raised as well.
So, I dont think that the issue of hypothyroidism is to be considered

However, I will agree that all your symptoms can be accounted for by hypothyroidism.
Generalized fatigue, heavy menses, depression, constipation, weight gain- all can be explained by hypothyroidism
However, all can also be accounted for by prozac.

All the symptoms you have mentioned can be caused as a side effect of prozac that you have been consuming. I will actually suggest you meet your doctor and have the medicine changed, or the dose modified.

Would prozac cause these symptoms even though i have been taking it for 18 years?

Detailed Answer:
Yes, the side effects can happen at any given time.
Granted, it may also be due to depression. In which case the drug needs to be changed again
