Signs of Hypothyroidism Thyroxine Conversion Block

The most common signs of hypothyroidism and thyroid hormone resistance (THR).

A sign is an abnormality experienced by the patient that others can see and independently confirm. Dry, scaly skin is a sign that you can show to your doctor. Other disorders can cause signs typical of hypothyroidism and THR. Because of this, its important not to rush to judgment and conclude that a thyroid disorder is the cause of your sign. Some signs may be so subtle that only you and your doctor may be certain that you had them only in their absence, after you reach an effective dose of thyroid hormone replacement. An example is the dull, listless appearance of some patients eyes, replaced after therapy with a bright radiance.
