What is generalized anxiety disorder (GAD)?

Generalized Anxiety Disorder (GAD) is characterized by persistent, excessive worry about various aspects of daily life — including work, health, family, and finances — that is difficult to control. GAD causes significant distress and may present with physical symptoms such as muscle tension, restlessness, fatigue, and difficulty sleeping.

What medications are used to treat anxiety?

First-line medications for anxiety disorders include SSRIs (selective serotonin reuptake inhibitors) such as sertraline, escitalopram, and paroxetine, and SNRIs (serotonin-norepinephrine reuptake inhibitors) such as venlafaxine and duloxetine. Buspirone is another option for generalized anxiety. Benzodiazepines may be used short-term for severe symptoms. Your provider will recommend the best option based on your specific condition and needs.

Can anxiety cause physical symptoms?

Yes. Anxiety commonly causes physical symptoms including rapid heartbeat, chest tightness, shortness of breath, sweating, trembling, nausea, dizziness, muscle tension, headaches, and gastrointestinal problems. These physical symptoms are real and can be distressing, but they are driven by the body's anxiety response and can improve with treatment.

How long does it take for anxiety medication to work?

SSRIs and SNRIs typically take 2 to 6 weeks to reach full effectiveness for anxiety disorders. Some improvement may be noticed within the first 1 to 2 weeks. Benzodiazepines work more quickly (within 30 to 60 minutes) but are generally used for short-term relief. Your provider will monitor your progress and adjust treatment as needed.

What is the difference between anxiety and an anxiety disorder?

Occasional anxiety is a normal stress response that everyone experiences. An anxiety disorder involves persistent, excessive worry or fear that is disproportionate to the situation and interferes with daily life for six months or more. Anxiety disorders include generalized anxiety disorder, social anxiety, panic disorder, and specific phobias. They are the most common mental health conditions and are highly treatable.

Can anxiety cause physical symptoms?

Yes. Anxiety commonly causes physical symptoms including rapid heartbeat, chest tightness, shortness of breath, muscle tension, headaches, stomach upset, dizziness, sweating, and trembling. These symptoms result from the body activating its stress response. Many people seek medical evaluation for physical symptoms before discovering anxiety is the underlying cause.

Is anxiety hereditary?

Anxiety disorders have a genetic component — having a first-degree relative with an anxiety disorder increases your risk. However, anxiety also develops through environmental factors including stressful life experiences, parenting styles, and learned behaviors. Both nature and nurture contribute, and effective treatment is available regardless of the cause.
