The hypothalamus is the body’s internal thermostat. It regulates the body temperature by secreting hormones through thyroid glands, that control how quickly the body burns calories and uses energy. HYPER-thyroidism is the OVER-production of the thyroid hormone
If you have many of the above symptoms, do a self test:
Keep a thermometer by your bed. When you awaken in the morning, place the thermometer under your arm for about 10 minutes (with the normal mercury thermometer). Or, get a digital thermometer that beeps when the temperature is ready for reading. Keep a log for five days. If your readings are consistently high at 98.3 degree F or higher, it may be an indication of hyperthyroidism. Some of these symptoms may be mistaken for menopausal symptoms. Consult your health care provider.
