Finally, we turn to the common endocrine glands that occasionally produce a disease. Many people are concerned about the function of the thyroid gland. This endocrine organ, located at the base of the neck just below the “Adam’s apple” (larynx) is an important regulator of the metabolism of the body. Its overactivity results in characteristic symptoms, such as a rapid pulse, bulging of the eyes, nervousness, tremor, and diarrhea.
Tumors of the thyroid gland, as well as the overproduction of the brain hormone stimulating the gland to produce excessive amounts of thyroid hormone may cause these problems. Blood tests are available to determine the level of thyroxine, the major hormone, as well as others circulating in the system.
Although stress may be a precipitating factor in the development of hyperthyroidism, a failure to respond to the recommended change in lifestyle with increased rest and physical exercise, should lead a person to seek medical counsel, as surgery is occasionally indicated.
Many more people are concerned about underactivity of the thyroid gland. This is often blamed for obesity but in reality is seldom the cause. A tendency to fluid retention, sluggishness, drying of the skin, constipation, and fluid retention should lead one to seek the appropriate blood tests and accurate diagnosis. The typical patient with advanced hypothyroidism, called myxedema, becomes very complacent, with subdued emotional responses and dull mental processes. This so-called “bovine placidity” is much less distressing to its possessor than to the patient’s associates.
Neurologic syndromes are occasionally mimicked by hypothyroidism. They normally clear rapidly with replacement therapy. Many different forms of thyroid medications are available, but should not be used unless a definite deficiency is diagnosed. In such case full hormone replacement becomes necessary, usually for life.
