The thyroid gland is a butterfly-shaped endocrine gland located in the lower front of the neck. It makes thyroid hormones, which help the body use energy, stay warm, and keep the brain, heart, muscles and other organs working properly.
Blood tests can evaluate thyroid function to determine if you are hypothyroid (your thyroid isn’t making enough thyroid hormone) or hyperthyroid (your thyroid is making too much thyroid hormone). With this knowledge, you can start medication that will regulate your thyroid and prevent complications.
