Taking your basal body temperature:
Your body temperature reflects your metabolic rate, which is largely determined by hormones secreted by the thyroid gland. The function of the thyroid gland can be determined simply by measuring your basal body temperature. All that is needed is a thermometer.
• Shake down the thermometer to below
95 F (35 C)
and place it by your bed before going to sleep.
• On waking place the thermometer in your armpit for a full 10 minutes. It is important to make as little movement as possible. Lying down and resting with your eyes closed is best.
Do not get up until the 10 minute test is completed.
• After 10 minutes, read and record the temperature and date.
• Record the temperature for at least three mornings (preferably at the same time of day) and give the information to your physician. Menstruating women must perform the test on the second third and fourth days of menstruation. Men and postmenopausal women can perform the test at any time.
Your basal body temperature should be between 97.6 F (36.4 C)
and 98.2 F (36.7 C). Low basal body temperatures are quite common and may reflect hypothyroidism. High basal body temperature (above 98.6 F, 37.0 C)
are less common, but may be evidence of hypothyroidism. Common signs and symptoms of hyperthyroidism include bulging eyeballs, fast pulse, hyperactivity, inability to gain weight, insomnia, irritability, menstrual problems and nervousness.
