Stress and hypothyroidismStress and hypothyroidism
Stress is known to be a significant contributor to thyroid dysfunction; this can be
environmental stress as well as lesser-considered homeostatic stress such as fluctuating
blood sugar levels and immune problems.Stress's effect on thyroid function can be
indirect, through its effects on blood sugar levels (dysglycemia), but it can also have
more direct effects. Stress may cause hypothyroidism or reduced thyroid functioning by
disrupting the HPA axis which down-regulates thyroid function, reducing the
conversion of T4 to T3, weakening the immune system thus promoting
autoimmunity , causing thyroid hormone resistance, and resulting in hormonal
imbalances. Indeed, excess estrogen in the blood caused by chronic cortisol elevations
can result in hypothyroid symptoms by decreasing levels of active T3. Stress also affects
thyroid functioning through the sympathetic nervous system. A 1994 study of refugees
from East Germany who experienced chronic stress found them to have a very high rate
of hypothyroidism or subclinical hypothyroidism, although not all refugees displayed
clinical or behavioral symptoms associated with this reduced thyroid
unctioning. TSH levels correlate positively with physiological stress.
