Hypothyroidism (underactive thyroid) Overview. Hypothyroidism (underactive thyroid) is a condition in which your thyroid gland doesn't produce enough of certain important hormones. Women, especially those older than age 60, are more likely to have hypothyroidism. Hypothyroidism upsets the normal balance of chemical reactions in your body.
Itâs fair to say that you canât maintain optimal health unless your thyroid is working pretty well. While the thyroid is vital to both genders, women have a greater tendency than men to suffer thyroid problems, especially hypo- (low) thyroid function. No one clearly knows why. It probably has to do with the interplay between our reproductive hormones â i.e., estrogen and progesterone â and our thyroid hormones.
