Dr. Friedman is low body temperature an unreliable sign of hypothyroidism?
Thyroid Disorders Hypothyroidism
When the production of thyroid hormone decreases below the normal body's need, the condition is referred to as hypothyroidism. Without enough thyroid hormone, the body becomes tired and run down. Every organ system slows—the brain slows down making it difficult to concentrate, the gut slows down causing constipation, and metabolism slows down causing weight gain. Although there are many different causes of an underactive thyroid gland, the resulting effect on the body is the same.
Many of the symptoms of hypothyroidism are very subtle and are experienced by people without thyroid disease. Thus, a lot of physicians overlook the symptoms of fatigue, weight gain and depression and attribute them to other causes. Physicians should check to see if thyroid disease is the cause of these everyday symptoms, because an underactive thyroid is very easy to treat.
