Do you often feel tired, sluggish, and sad? Have you gained weight that you can’t seem to blame on overeating? You could be among the estimated 27 million with hypothyroidism, a malfunctioning of the thyroid. This tiny butterfly-shaped gland near the base of the neck is responsible for regulating several important bodily functions. The result can be fatigue, a slow metabolism resulting in weight gain, dry skin and hair, foggy thinking, and depression. The symptoms are seen in women more often than in men.
