Underactive thyroid (hypothyroidism) is a well-known condition; in contrast, overactive thyroid (hyperthyroidism) is a less appreciated but still important endocrine problem.

Recent reports found that mild or subclinical hyperthyroidism, in which the thyroid hormones, T4 and T3 are normal, but the pituitary hormone, TSH, is suppressed, may cause symptoms including fatigue, nervousness, anxiety, shortness of breath, palpitations, trouble sleeping, increased appetite, loose stool or diarrhea, tremor and weight loss, although rarely, weight gain occurs. Many patients with mild hyperthyroidism may have only a few of these symptoms. Most of these symptoms will worsen without treatment, and the patient may suffer osteoporosis (thinning of the bones) or heart disease. With proper diagnose and treatment, however, symptoms improve. Therefore, one should see an Endocrinologist with expertise in thyroid disorders if you could have hyperthyroidism.

In subacute thyroiditis, the thyroid is tender and the patient has symptoms of a viral illness. Only in Grave’s disease is exophthalmos seen.

To control symptoms of hyperthyroidism due to all causes, some patients may benefit from a beta-blocker. Dr. Friedman recommends atenolol.
