The thyroid is like a speed control or accelerator for the body. An overactive thyroid can leave a person feeling 'revved up', even when they should be getting ready to sleep at bedtime. An underactive thyroid slows a person down, and may cause symptoms of depression, fatigue, and weight gain. Thyroid conditions are relatively common, and can be treated.
Symptoms of hyperthyroidism arise from the elevated levels of thyroid hormones produced by the overactive thyroid gland. Excessive intake of thyroid hormones can produce these symptoms as well. Characteristic symptoms include a rapid heart rate, excessive sweating, intolerance to heat, tremor, nervousness, or agitation. Other symptoms can include fatigue, weight loss, hair loss, increased appetite, problems with concentration, frequent bowel movements, and irregular or decreased menstrual blood flow in women. Sometimes, thyroid nodules or an enlarged thyroid gland (goiter) are apparent. With severe hyperthyroidism, cardiac arrhythmias, fever, high blood pressure, and heart failure can develop.
