Explanation: 

Detailed explanation-1: -A thyroid problem can exist in the form of hyperthyroidism or hypothyroidism. Hyperthyroidism occurs when there is excessive thyroid hormone synthesis or release. Hypothyroidism, on the other hand, happens due to inadequate thyroid hormone production.

Detailed explanation-2: -Too little production of thyroxine by the thyroid gland is known as hypothyroidism. It may be caused by autoimmune diseases, poor iodine intake or caused by the use of certain drugs. Sometimes, the cause is unknown.

Detailed explanation-3: -These hormones are called thyroxine and triiodothyronine. They affect processes such as heart rate and body temperature, and help convert food into energy to keep the body going. In hyperthyroidism, the thyroid gland produces too much thyroxine or triiodothyronine, which speeds up the body’s metabolism.
