Generalized Anxiety Disorder
Generalized anxiety disorder (GAD) is more than just everyday stress. It's persistent, hard-to-control worry that lasts for months and affects how you live your life.
What is GAD?
Everyone worries from time to time, but people with GAD experience excessive worry about many different things — work, health, family, finances, or even small daily tasks — on most days, for six months or more. The worry feels out of proportion to the actual situation and is difficult to turn off, often interfering with the ability to focus or get things done.
Unlike ordinary worry, GAD-related worry is more intense, longer lasting, and frequently occurs even when there is no obvious reason to be concerned. It also tends to come with noticeable physical symptoms.
Common symptoms
To be diagnosed with GAD, adults typically experience three or more of the following symptoms on most days over a period of at least six months. Children may only need one.
- Restlessness — feeling keyed up, on edge, or unable to relax
- Fatigue — being easily tired, even without heavy exertion
- Difficulty concentrating — trouble focusing, or your mind going blank
- Irritability — feeling unusually short-tempered
- Muscle tension — persistent tightness, aches, or soreness
- Sleep problems — difficulty falling or staying asleep, or sleep that feels restless and unsatisfying
Other physical symptoms may include trembling, sweating, nausea, diarrhea, muscle twitching, and an exaggerated startle response. Stress-related conditions like irritable bowel syndrome and frequent headaches often go along with GAD as well.
What people with GAD commonly worry about
Adults
- Job responsibilities and work performance
- Personal health and finances
- The health and safety of family members
- Bad things happening to their children
- Minor everyday matters like household chores or being on time for appointments
Children and teens
- School performance and grades
- Being good enough or doing things perfectly
- Catastrophic events like natural disasters
- Constantly seeking reassurance from adults
Older adults
- Chronic health conditions
- Personal safety, especially fear of falling
How common is it?
GAD is found across all cultures and backgrounds, though the specific things people worry about and the way symptoms show up can vary. In the United States, people who have experienced racism and ethnic discrimination are at higher risk.
When does it start and how does it progress?
The average age of onset is around 35, though many people describe having been anxious for as long as they can remember. It is uncommon for GAD to begin before adolescence.
GAD tends to be a chronic condition — symptoms may come and go in severity over time, but full remission without treatment is uncommon. The earlier it begins, the more likely it is to occur alongside other mental health conditions.
Risk factors
Personality and temperament
People who tend toward negative thinking, shyness (behavioral inhibition), or a heightened sensitivity to potential threats may be more prone to developing GAD.
Life experiences
Difficult childhood experiences, overprotective parenting, or growing up in a highly controlling environment can increase the risk.
Genetics
About one-third of the risk for GAD is inherited. The genetic factors that contribute to GAD overlap with those for depression and other anxiety disorders.
How GAD affects daily life
The constant worry that comes with GAD takes a real toll. It consumes time and mental energy, making it harder to be productive and efficient at work or school. In the United States alone, GAD accounts for an estimated 110 million disability days per year.
People with GAD tend to use more medical resources, experience decreased work performance, and face an increased risk of heart-related health problems. The impairment is significant on its own, even without other co-occurring conditions.
GAD and suicidal thoughts
GAD is linked to increased suicidal thinking and behavior. Studies show it is the anxiety disorder most frequently identified in people who have died by suicide. If you or someone you know is struggling, please reach out for help.

Conditions that often occur alongside GAD
GAD rarely occurs in isolation. It commonly appears alongside:
- Other anxiety disorders (such as social anxiety or panic disorder)
- Depression
Less commonly, it may co-occur with substance use disorders, conduct disorders, or other mental health conditions.
How is GAD identified?
A healthcare professional diagnoses GAD by looking for a specific pattern: excessive, hard-to-control worry occurring on most days for at least six months, accompanied by physical symptoms, and causing meaningful distress or difficulty functioning in daily life.
Importantly, the symptoms must not be caused by a medication, substance use, or another medical condition (such as a thyroid problem). The provider will also consider whether the symptoms might be better explained by a different mental health condition, such as panic disorder, social anxiety, OCD, or PTSD.
What to do next
If you recognize yourself or someone you care about in these descriptions, know that GAD is very treatable. Effective options include therapy (particularly cognitive behavioral therapy), medication, lifestyle changes, and stress management techniques. A mental health professional can help determine the best approach for your situation.
