Hypothyroidism is a condition in which your thyroid gland does not produce enough thyroid hormones. It refers to a state in which your thyroid hormones production is bellow normal. It is also called under active thyroid or low thyroid, which can slow down many of your body’s functions such as your metabolism and can decrease the cardiac activity. Hypothyroidism affects women more frequently than men.

Furthermore, blood tests are the only way to reliably confirm a diagnosis of hypothyroidism.

Thyroid Gland

Last updated: January 10, 2024

Thyroid is a small gland (about 2 inches long) which has the shape like a butterfly that lies in the front of your neck. It has two sides called lobes, located either side of your windpipe. Further, these two lobes of the gland are connected by a small tissue called the isthmus.

Thyroid is a vital hormone gland which plays a major role in metabolism, growth, development, temperature, weight and heart rate of the human body by constantly releasing a steady amount of thyroid hormones (T3 and T4) into the bloodstream. Also, during infancy and childhood, adequate thyroid hormone is crucial for brain development.
