Symptoms of Hypothyroidism

The symptoms of hypothyroidism are usually very subtle and develop gradually, most often over a period of years. Every individual experiences symptoms differently, and will present with various combinations of symptoms. Developed with TPA-UK medical advisor Dr Barry Peatfield, this comprehensive checklist (in PDF format) can be given to your doctor for a review into your symptoms. To view this checklist, you’ll need Adobe Acrobat Reader.

Signs of Hypothyroidism

Apart from the symptoms provided in the Hypothyroid Symptoms Checklist, you also need to know 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, it’s 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 yourself 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.
