Understanding More About Hypothyroidism

Hypothyroidism, also known as underactive thyroid, is a condition that results when your thyroid gland does not produce enough hormones.1,2 Those hormones include levothyroxine (T4 ) and liothyronine (T3), which help regulate your weight, energy level, mood, and other bodily functions.3,4 Hypothyroidism affects an estimated 10 million Americans and is 5-10 times more common in women than men.

How Your Thyroid Works—Or Doesn’t Work

Your thyroid gland is a small butterfly-shaped organ located at the base of your neck. The thyroid creates hormones that control the speed of your metabolism, as well as how the body regulates body temperature and heart rate.7 T4 is the main type of thyroid hormone produced by the thyroid gland. However, T3 is the active form of thyroid hormone that impacts your cells.7 Most T3 is produced by the body converting T4 to T3.7

The pituitary gland, which is located in your brain, keeps checking the thyroid hormone levels in your body to make sure there isn’t too much—or too little.6

In hypothyroidism, either the thyroid gland or the pituitary gland is not working in a way to create the proper thyroid hormone balance for your body.5 10% to 15% of people still have hypothyroidism symptoms despite treatment with T4 alone.8 ADTHYZATM can supplement the T4 and T3 produced by the thyroid, and may be an option for patients still experiencing persistent sypmptoms.9
