Hypothyroidism - secondary

Alternative Names:

Pituitary hypothyroidism
Treatment:

The purpose of treatment is to replace the deficient thyroid hormone. Levothyroxine is the most commonly used medication. The lowest dose effective in normalizing thyroid function is used. Life-long therapy may be necessary. Medication must be continued even when symptoms subside.

After replacement therapy has begun, report any symptoms of increased thyroid activity (hyperthyroidism), such as restlessness, rapid weight loss, and sweating.

A high-fiber, low-calorie diet and moderate activity will help relieve constipation and promote weight loss if weight was gained during the time when thyroid activity was low.

In individuals with accompanying hypoadrenalism, steroid replacement must be instituted before thyroid replacement is begun.

In patients who have hypothyroidism caused by a pituitary tumor, surgery may be required. However, surgery may not cure the hypothyroidism, and thyroid replacement will still be needed.

Myxedema coma is treated by intravenous (IV) thyroid replacement and steroid therapy. Supportive therapy of oxygen, assisted ventilation, fluid replacement, and intensive care nursing may be indicated.

Expectations (prognosis):

With early treatment, return to the normal state is usual. However, relapses will occur if the medication is not continued. Myxedema coma can result in death.

Complications:

Myxedema coma, the most severe form of hypothyroidism, is rare. It may be precipitated by an infection, illness, exposure to cold, or certain medications.

Symptoms and signs of myxedema coma include:
