Short answer: generalized anxiety disorder (GAD) is persistent, hard-to-control worry about many everyday things, lasting six months or more and often coming with muscle tension, poor sleep and fatigue. It is one of the most treatable conditions in psychiatry, usually with therapy, medication or both.
How GAD differs from ordinary worry
Everyone worries before a job interview or a medical test. With GAD the worry jumps from topic to topic (health, money, family, work) even when nothing is wrong, and it is out of proportion to the actual risk. People often describe it as a background hum of dread that they cannot turn off.
Common symptoms
- Restlessness or feeling keyed up
- Getting tired easily
- Trouble concentrating or the mind going blank
- Irritability
- Muscle tension, headaches or jaw clenching
- Trouble falling or staying asleep
- Stomach problems, such as nausea or irritable bowel symptoms
What causes it
There is rarely one cause. Family history, temperament, long periods of stress and medical factors all play a part. A good evaluation also checks for things that can mimic anxiety: thyroid problems, high caffeine intake, some medications, and alcohol or cannabis withdrawal.
Treatment that works
- Cognitive behavioral therapy (CBT): teaches you to notice worry patterns, test anxious predictions and tolerate uncertainty.
- Medication: SSRIs and SNRIs are first-line options for many adults. Buspirone is sometimes used. Benzodiazepines are generally avoided for long-term use because of dependence risk.
- Lifestyle foundations: regular sleep, exercise and less caffeine make other treatments work better.
Medication usually takes four to six weeks to show its full effect, so regular medication management visits matter in the first months.
A closer look at the worry cycle
GAD is kept going by a loop. A trigger (an email from your boss, a child’s cough) sets off “what if” thinking. Worry feels productive, as if it prepares you, so the brain keeps doing it. Avoidance and reassurance seeking, such as re-reading messages or asking a partner if everything is okay, bring short relief and strengthen the loop. Treatment interrupts each step: noticing the first “what if,” scheduling a short daily worry time instead of worrying all day, and practicing letting uncertain questions stay unanswered.
Physical symptoms are part of anxiety
Many people with GAD first visit a primary care doctor for headaches, chest tightness, stomach problems or insomnia. It is worth ruling out medical causes, and once that is done, recognizing these symptoms as anxiety is a relief in itself. Slow breathing, progressive muscle relaxation and regular aerobic exercise directly lower the body’s stress response and make worry easier to manage.
What your first visit looks like
At a first appointment your psychiatrist asks when the worry started, what it focuses on, how it affects sleep and work, and about family history, alcohol, caffeine and other medications. Short questionnaires such as the GAD-7 give a baseline so you can see progress. You leave with a plan, which may be therapy, medication, lifestyle steps or a combination.
Frequently asked questions
Will I need medication forever?
Not necessarily. Many people take medication for 6 to 12 months after they feel well, then taper slowly with their psychiatrist while keeping the skills they learned in therapy.
Can children have GAD?
Yes. In children it often shows up as constant reassurance seeking, stomach aches and perfectionism about school. Our child and adolescent psychiatry team evaluates kids and teens.
