Hyperthyroidism refers to the syndrome produced due to excess thyroid hormones. As mentioned before thyroid is vital to maintain body metabolism. Excess thyroid hormone increases body metabolism and causes weight loss. Apart from weight loss patients also complain of irritability, nervousness, tremulousness, poor sleep, loose motions and heat intolerance. Though this condition is not as common as Hypothyroidism, women with hyperthyroidism still outnumber men. Hyperthyroidism is caused by a multitude of conditions ranging from tumours in brain to generalised growth of the thyroid gland. A complete description of the causes is beyond the scope of this article, but suffices to know that the symptoms of hyperthyroidism are caused by an excess of thyroid hormone and vice versa. The diagnosis of hyperthyroidism is also established by hormone assays of thyroid hormones. This condition is primarily managed by medicines which block the production of thyroid hormone by the thyroid. It may also be treated by removing one half of the thyroid gland or by using a radioactive material which will kill all thyroid tissue. Use of radioactive material for ablation of thyroid generally leads to hypothyroidism over 5-10 years and hence women undergoing radioiodine ablation must be under regular follow up and early thyroxine replacement must be begun, if hypothyroidism is diagnosed in these women. Hyperthyroidism causes plenty of problems to the pregnant women. Apart from the risk of pre term delivery and stillbirth, hyperthyroidism is associated with much complication in pregnancy. Untreated hyperthyroidism can lead to heart failure and death in pregnant women. Apart from this problem, thyroid hormone assay is not very accurate in pregnancy because β--hcg, produced during pregnancy itself has a stimulatory action on the thyroid. So under these circumstances it become difficult to decide if the signs and symptoms of thyroid excess are due to a problem with thyroid or not. Treatment of hyperthyroidism during pregnancy also poses problems. All drugs used in hyperthyroidism cross the placenta and can cause birth defects in your baby. However one of the drugs-propylthiouracil does not cross the placenta in sufficient quantities and is considered safe for use in pregnancy. Thus both hyper and hypothyroidism cause many metabolic imbalances and are responsible for many deleterious effects.
