Underactive thyroid, means that the thyroid gland is not producing enough thyroid hormone.
In many, if not in most, patients, the problem is elsewhere.
When the thyroid produces enough thyroid hormone, for a number of reasons it may not be bioactive.( it does not enter the cells and it just circulates in the serum).
The standard thyroid tests (T3, T4 & TSH) do not detect this, as they only indicate the serum circulating levels.
I have a friend who has narcolepsy, adrenal fatigue & secondary hypothyroidism (resulting from the adrenal fatigue).
Hope this helps.

Thank you for getting back to me.
I have been tested for an under active thyoid as I have a narcolepsy and they checked this when I first showed my symptoms of narcolepsy.
Is this what you refer to?
It would be good to know your estrogen and progesterone levels, to ensure your estrogen to progesterone ratio is right.
What are you on now?
Unfortunately standard Thyroid testing does not indicate Hypothyroidism
type 2, which is similar to diabetes 2. The serum levels are fine, yet the
thyroid function (in the cells) is low (thyroid resistance)
For this you need Free T3, Free T4 AND Reverse T3
Cheers.

Thank you for your response. I have been on both the combined pill and an estrogen only pill. I have had a thyroid test and that's all normal also.

Hi Candie.
Have you looked into estrogen dominance or other hormonal imbalance?
What birth control are you using, if any?
