Thyroid

The thyroid is a small, butterfly-shaped gland located at the base of the neck, just below Adam's apple. The thyroid gland makes two main hormones: thyroxine (T-4) and triiodothyronine (T-3). These hormones affect every cell in the body. They support the rate at which the body uses fats and carbohydrates. When your thyroid makes either too much or too little of these important hormones, it’s called a thyroid disease. There are several different types of thyroid disease, including hyperthyroidism, hypothyroidism, thyroiditis, and Hashimoto’s thyroiditis.
