Hyperthyroidism

The thyroid gland is the butterfly shaped gland located in the neck region. It's one of the important glands in our endocrine system. The Thyroid gland is responsible for the production of thyroxine hormones T3,T4 . It controls the body temperature and hence acts as a barometer. It controls our heart , lungs, and also helps in metabolism It also regulates calcium levels in our body and plays a important role in energy production. Malfunctioning of these glands can lead to thyroid problems such as hyperthyroidism,hypothyoridism,thyroiditis, and even goiters.

Hyperthyroidism or overactive thyroid is a condition where the thyroid glands produces excess of T3 and T4
which is the opposite of underactive thyroid or hypothyroidism where there is a reduced production of T3 and T4 hormones respectively. The most common cause of hyperthyroidism is Grave's disease.

Hyperthyroidism can also lead to thyrotoxicosis. Thyrotoxicosis can be caused due to inflammation of thyroid gland which produces excess of thyroid hormones.

TSH is the thyroid stimulating hormone which is necessary for the production of T3 and T4 hormones. The TSH is regulated by TRH which is produced in hypothalamus.
