Comprehensive Information, Resources, and Support on Hyperthyroidism

Thyroid hormone is an important hormone that plays a significant role in metabolism. Hyperthyroidism may be present with significant symptoms. Since overactive thyroid gland increases the metabolism, many individuals initially have a lot of energy. However, as the body tends to break down, feeling lethargic is quite common.

Hyperthyroidism is caused by many reasons. Most commonly, the entire thyroid gland is overproducing thyroid hormone. But sometimes, only a single nodule (part of the thyroid gland) is responsible for the over secretion of hormone. The nodule working abnormally is called as “hot nodule”.

The term hyperthyroidism refers to any condition in which the body produces more than required amount of thyroid hormone. In other words, the thyroid gland is overactive and functioning abnormally. Another term that you might hear for this problem is thyrotoxicosis, which refers to high thyroid hormone levels in the bloodstream, irrespective of their source.
