Dr. Susan Koven practices internal medicine at Massachusetts General Hospital. In a recent (2013) Boston Globe column, she wrote:

In the past few years, I've observed an epidemic of sorts: patient after patient suffering from the same condition. The symptoms of this condition include fatigue, irritability, insomnia, anxiety, headaches, heartburn, bowel disturbances, back pain, and weight gain. There are no blood tests or X-rays diagnostic of this condition, and yet it's easy to recognize. The condition is excessive busyness.
