1 That, in turn, may reach the point where the mere idea of doing things that preceded the first panic attack triggers terror or dread of future panic attacks, resulting in the individual with panic disorder being unable to drive or even step out of the house.
TSH levels in your bloodstream rise or fall depending on whether there is enough thyroid hormone in your system to meet your bodyâs needs. Higher levels of TSH push the thyroid to produce more hormone. Low TSH levels mean the thyroid is producing more than enough hormone. TSH levels can change a great deal with minor increases and decreases in T4. This is a very tightly regulated feedback process between the pituitary and the thyroid gland.
Doctors are taught that if active thyroid (T3) levels drop, the TSH will increase. Thus, endocrinologists and other doctors tell patients that an elevated TSH is the most useful marker for diminished T3 levels and that a normal TSH indicates that their thyroid status is âfineâ. The TSH is, however, merely a marker of pituitary levels of T3 and not of T3 levels in any other part of the body.
