An underactive thyroid -- hypothyroidism -- is estimated to affect as many as 10 to 20 percent of women in their lifetimes, and is more common in women than men. The symptoms of hypothyroidism include fatigue, depression, weight gain, hair loss, muscle and joint pains, and many other chronic and debilitating symptoms. Low thyroid can also be linked to increased levels of LDL -- bad cholesterol -- and heart disease.
Hyperthyroidism, or an overactive thyroid, can cause symptoms like anxiety, nervousness, irritability, restlessness, sweating, and a rapid or irregular heartbeat. These symptoms are the result of overproduction of the hormone thyroxine, which speeds up your body's metabolism.
