The thyroid gland is responsible for the secretion and regulation of hormones (T3 and T4) in the body. These hormones play a key role in food metabolism, mood and sexual health. It is important to maintain normal production of these hormones in the body as an increase or decrease in hormonal levels signifies clinical complications. Here are few medical conditions that affect thyroid functioning and cause hormonal imbalances
Excessive secretion of thyroid hormones (hyperthyroidism) is caused due to
Grave's disease It causes enlargement of the thyroid glands and thus, causes increased secretion of hormones in the body. This condition is commonly seen in adults.
Nodules in the gland Excessive secretion of hormones by the thyroid gland may be caused due to the growth of nodules (lumps) on the gland.
Medications Intake of medications prescribed to initiate hormonal secretion in high amounts and drugs containing high levels of iodine (certain medicines and cough syrups) cause hyperthyroidism.
Thyroiditis Inflammation of the gland called thyroiditis causes the release of stored thyroid hormones.
Excess secretion of TSH Increased secretion of thyroid stimulating hormone (TSH) by the pituitary gland causes excess secretion of the thyroid hormones.
Low levels of thyroid hormones (hypothyroidism) are commonly caused due to the following clinical conditions
