Thyroid disorders impact how your body uses energy. The thyroid gland in your neck makes hormones that control heart rate, energy level, body temperature, and weight. When the thyroid makes too many or too few hormones, your body's functions can go haywire. Hypothyroidism happens when your thyroid doesn’t make enough hormones. This slows your metabolism down, making you feel tired. You might gain weight, feel cold, or have muscle weakness. Other symptoms are dry skin, thin hair, pain, irregular periods, high cholesterol, and depression. Hypothyroidism is usually treated with a daily thyroid hormone replacement pill like levothyroxine to get levels back to normal. Hyperthyroidism is when your thyroid is overactive and makes too much thyroid hormone. Symptoms are rapid heartbeat, anxiety, trouble sleeping, weight loss, diarrhea etc. Three common causes are Graves’ disease, thyroid nodules, and thyroiditis (thyroid inflammation). Hyperthyroidism is treated with medicines, radioactive iodine, or thyroid surgery. At *, our endocrinologists specialize in preventing, diagnosing, and treating thyroid disorders.
