If your thyroid–a butterfly-shaped gland in the neck that helps control metabolism–is underactive, you may experience weight gain, constipation, cold sensitivity, or fatigue (hypothyroidism). If it's overactive, you may lose weight quickly, sweat a lot, have a fast heartbeat, or feel nervous or moody (hyperthyroidism). Luckily, thyroid treatments are often effective.
