Hyperthyroidism
 I have hypothyroidism and have been taking levothyroxine for almost two years. Blood tests show that my levels are stable/normal with this medication. Otherwise, I am a relatively healthy 50-year-old female, and not taking other medications except a multivitamin. I would like to get off the medicine eventually. Is this possible?
 Hypothyroidism is a condition caused by the deficiency of thyroid hormones. In the adult it is usually caused primarily by the failure of the thyroid gland to produce these hormones. Secondarily, it may be due to failure of the pituitary gland or the hypothalamic area of the brain to produce the necessary stimulation for the thyroid hormones to be produced.
The most common cause of hypothyroidism in adults is Hashimoto’s disease. This is an autoimmune disease that results in the destruction of the thyroid gland. An autoimmune disease is a condition in which the body fails to recognize a part of itself and develops destructive antibodies against itself, in this instance against the thyroid. Other conditions may cause hypothyroidism, including surgical removal, radioactive treatment, and lithium therapy. In parts of the world a lack of iodine is present in the diet, and this can result in hypothyroidism associated with enlargement of the thyroid gland (goiter). The addition of iodine to salt has significantly reduced this problem in many areas.
You are on the appropriate treatment, and your physician is treating you carefully and monitoring your blood levels. The fact that these levels are stable shows that you are on the correct dosage. You are fortunate not to be on any other medications. It is important for you to know that you will have to take thyroid hormone supplementation the rest of your life.
The most important side effects of replacement therapy result from either underdosing or overdosing. Excessive doses will result in weight loss, tremors, intolerance of hot weather, palpitations, and nervousness. Insufficient thyroid hormone results in weight gain, lethargy, tiredness, depressed mental activity, anemia, and elevated cholesterol. With careful follow-up as your physician is currently doing, you can continue your present therapy with peace of mind. You are supplementing that which is essential and needed.
As far as diet and lifestyle are concerned, it is important to have a nutritious and balanced diet (we recommend a lacto-ovo vegetarian diet). Regular exercise at least five days per week is important to enjoy the best health. Be sure to discuss your exercise program with your health-care provider to ensure that your exercise is appropriate for your current health status. You should be able to continue to lead a full and healthy life with your current therapy.
