Generalized anxiety disorder (or GAD) is marked by excessive, exaggerated anxiety and worry about everyday life events for no obvious reason. People with symptoms of generalized anxiety disorder tend to always expect disaster and can’t stop worrying about health, money, family, work, or school.

Everyone feels anxiety now and then — and there can be good reasons why. But in people with GAD, the worry is often unrealistic or out of proportion for the situation. Daily life becomes a constant state of worry, fear, and dread. Eventually, anxiety can even dominate a person’s thinking so much that they find it hard to do routine things at work or school, socially, and in their relationships. But there are treatments to ease anxiety so it’s not running your life.

About 2% of U.S. adults have generalized anxiety disorder in any given year. It’s more commonly reported in women than in men.
