The thyroid gland found in your body uses iodine and converts it into the thyroid hormones thyroxine and triiodothyronine (T3 and T4). These hormones are then released into the bloodstream where they help control a variety of the body’s functions such as metabolism, sex drive, temperature, and growth. Diseases of the thyroid can cause it to make either too little or too much of these hormones, resulting is symptoms such as restlessness, fatigue, or weight gain. Thyroid disease affects women 5x more than it does men, with one in eight women having thyroid problems at some point during her lifetime. Standard treatment for hypothyroidism (an underactive thyroid) involves daily intake of a synthetic thyroid hormone such as levothyroxine, an oral medication that restores natural hormone levels. 

Everyone has two adrenal glands located on top of each of your kidneys. Adrenal glands produce hormones that help regulate your metabolism, immune system, blood pressure, your response to stress, and other essential functions. There are several disorders related to the adrenal glands which can lead to symptoms such as weight gain, acne, high blood pressure, muscle and bone weakness, irritability, and slow growth rates in children. Medications used to treat adrenal abnormalities are mostly oral corticosteroids such as hydrocortisone which replaces cortisol.
