OTHER ATHLETES AFFECTED
Olympic gold medal sprinter Gail Devers
While at the University of North Carolina, Overbeck won four NCAA championships. She was named to Soccer America's freshman team of the year and received All-American honors her sophomore, junior, and senior years while at UNC.
Overbeck has played 161 times for the national team since her debut in 1988 and is considered one of the world's best defenders. She captained the U.S. team to the gold medal in the 1996 Olympics, playing every minute of the team's five matches. That same year, she was named to the U.S. Women's Cup '96 All-Tournament team. Now 31 years old, Overbeck helped lead the U.S. to the 1999 Women's World Cup title.
HOW IT HAPPENED
Graves' disease is an autoimmune disorder in which the body's immune system, for largely unknown reasons, produces antibodies to parts of the body. In Graves', the antibody acts like a hormone and stimulates the production of thyroid hormones by the thyroid gland. The thyroid gland in the front of the neck becomes larger, and the extra hormones it secretes tend to speed up the body's metabolism. The patient may have nervousness, excessive sweating, fatigue, high blood pressure, muscle cramps, fast pulse, weight loss, and frequent bowel movements. Graves' disease is commonly associated with bulging, watery eyes. It is far more common in women than in men and tends to happen between the ages of 20 and 40. In many cases, there is a tendency for this disease to run in families.
For the last few months, Overbeck has said she hadn't felt well, especially during training.
Symptoms of Graves' disease may be mild or severe, depending on how overactive the thyroid gland is. The symptoms are caused by the increased metabolism that occurs in various body organs as a result of the high levels of the thyroid hormones, known as T4 and T3, present in the blood.
