What Is General Anxiety Disorder? Symptoms, Causes, and Treatment

Anxiety / By /

Do you constantly worry about everyday things—even when there’s no real reason to? If excessive anxiety disrupts your life, you might be dealing with General Anxiety Disorder (GAD), a chronic condition marked by persistent, uncontrollable worry.

Unlike normal stress that comes and goes, GAD lingers, making even minor decisions feel overwhelming. The good news? GAD is treatable. This guide covers its symptoms, root causes, and the most effective treatments—so you or a loved one can find relief.

What Is General Anxiety Disorder (GAD)?

Generalized Anxiety Disorder is a long-term mental health condition where a person experiences excessive anxiety about various aspects of life—work, health, relationships, or even routine tasks—for six months or more.

Unlike phobias (fear of specific things) or panic disorder (sudden intense fear), GAD involves a constant sense of dread that isn’t tied to one situation. According to the Anxiety & Depression Association of America (ADAA), 6.8 million U.S. adults struggle with GAD, and women are twice as likely as men to develop it.

Key difference: Normal anxiety is temporary (e.g., nervousness before a job interview), while GAD is chronic and disproportionate to the actual risk.

Symptoms of General Anxiety Disorder

GAD affects both the mind and body. Symptoms can be grouped into three categories:

1. Emotional & Cognitive Symptoms

  • Excessive, uncontrollable worry (“What if something bad happens?”)

  • Overthinking decisions, even small ones

  • Difficulty concentrating (“mind going blank”)

  • Feeling irritable or on edge

2. Physical Symptoms

  • Muscle tension (clenched jaw, back pain)

  • Fatigue (even without physical exertion)

  • Stomachaches, nausea, or IBS-like symptoms

  • Trouble sleeping (insomnia or restless sleep)

  • Rapid heartbeat, sweating, or trembling

3. Behavioral Symptoms

  • Procrastination due to fear of making mistakes

  • Avoiding situations that trigger anxiety

  • Seeking constant reassurance from others

Note: If these symptoms persist most days for over six months and interfere with daily life, it may be GAD.

What Causes GAD?

Researchers believe GAD develops from a mix of biological, environmental, and psychological factors:

1. Biological Causes

  • Genetics: If a close family member has GAD, you’re more likely to develop it.

  • Brain Chemistry: Imbalances in serotonin, dopamine, and GABA (neurotransmitters that regulate mood).

  • Brain Structure: Overactivity in the amygdala (the brain’s “fear center”).

2. Environmental Triggers

  • Childhood trauma (abuse, neglect, or bullying)

  • Chronic stress (financial problems, job pressure, caregiving)

  • Major life changes (divorce, moving, loss of a loved one)

3. Personality & Temperament

  • Perfectionists and high achievers

  • People who avoid conflict or suppress emotions

  • Those with a history of other anxiety disorders

How Is GAD Diagnosed?

There’s no lab test for GAD. Instead, doctors use:

  1. Clinical interviews – Discussing symptoms, medical history, and lifestyle.

  2. Psychological assessments – Such as the GAD-7 questionnaire, which measures anxiety severity.

  3. Rule-out tests – Checking for thyroid issues, heart conditions, or caffeine overuse that mimic anxiety.

When to see a professional? If anxiety:
✔ Lasts most days for 6+ months
✔ Feels uncontrollable
✔ Disrupts work, relationships, or daily functioning

Effective Treatments for GAD

The best outcomes usually come from a mix of therapy, medication, and lifestyle changes.

1. Psychotherapy (Talk Therapy)

  • Cognitive Behavioral Therapy (CBT): Helps reframe negative thoughts. (“What’s the evidence this worry will come true?”)

  • Acceptance and Commitment Therapy (ACT): Teaches mindfulness and value-based living.

2. Medications

  • SSRIs (e.g., sertraline, escitalopram): Boost serotonin levels.

  • SNRIs (e.g., venlafaxine): Target serotonin and norepinephrine.

  • Buspirone: A non-addictive anti-anxiety medication.

  • Short-term options: Benzodiazepines (e.g., Xanax, Valium) for acute relief (risk of dependency).

3. Lifestyle & Self-Help Strategies

  • Exercise: 30 minutes of cardio reduces cortisol (stress hormone).

  • Mindfulness & Meditation: Apps like Headspace or Calm can help.

  • Limit caffeine & alcohol: Both worsen anxiety.

  • Sleep hygiene: Poor sleep exacerbates worry.

4. Alternative Treatments

  • Omega-3 supplements (may reduce inflammation linked to anxiety).

  • Yoga & Tai Chi: Combine movement with breathwork.

  • Acupuncture: Some studies show reduced anxiety symptoms.

How to Help Someone with GAD

If a loved one has GAD:
✅ Listen without judgment – Avoid saying, “Just relax.”
✅ Encourage professional help – Offer to help find a therapist.
✅ Practice patience – Recovery takes time.

Avoid:
❌ Dismissing their fears (“You’re overreacting”).
❌ Enabling avoidance (e.g., canceling plans for them).

Final Thoughts: GAD Is Manageable

Living with GAD can feel exhausting, but effective treatments exist. If you see yourself in these symptoms, reach out to a therapist or doctor. With the right support—whether therapy, medication, or lifestyle changes—you can reduce anxiety’s grip and regain control.
