What to Ask Your Doctor If You’re Having Anxiety Symptoms

Anxiety is one of the most prevalent mental health experiences in adults, and yet it remains underrecognized and undertreated. Persistent worry, physical tension, difficulty sleeping, and a sense that something is always wrong are not simply personality traits or character weaknesses—they can reflect a clinically meaningful anxiety disorder that responds to evidence-based approaches. This article explains anxiety in plain terms, what major guidelines recommend regarding screening and care, and the questions worth raising with your clinician.

What Anxiety Symptoms Are in Plain Language

Everyone experiences anxiety at times—it is a normal human response to perceived threat or uncertainty. Clinical anxiety disorders are distinguished by their persistence, intensity, and impact: worry or fear that is difficult to control, occurs more days than not, and significantly interferes with work, relationships, sleep, or daily functioning.

The most common anxiety disorder in adults is generalized anxiety disorder (GAD), characterized by excessive, difficult-to-control worry about multiple areas of life (work, health, family, finances) for most days over at least six months. Other common anxiety disorders include panic disorder, social anxiety disorder, and specific phobias. Post-traumatic stress disorder (PTSD) is separately classified but shares features with anxiety disorders.

Anxiety can manifest physically: muscle tension, headaches, gastrointestinal symptoms, heart palpitations, fatigue, and difficulty concentrating are all recognized physical manifestations. Many people with anxiety present to primary care with physical complaints before the emotional component is identified.

Why It Matters: What Guidelines Say

Anxiety disorders are among the most common mental health conditions worldwide. The World Health Organization (WHO)^[1] notes that one in eight people globally lives with an anxiety or depressive disorder.

The U.S. Preventive Services Task Force (USPSTF) recommends screening adults under 65 for anxiety disorders in primary care settings^[2]. The USPSTF found adequate evidence that screening tools—particularly the GAD-7 and the abbreviated GAD-2—can accurately identify people with clinically significant anxiety in primary care populations, and that effective treatments exist.

The American Psychological Association (APA) and APA’s clinical resources recognize lifestyle factors as meaningful adjuncts to anxiety management^[3], noting that healthy lifestyle behaviors promote mental health and can be used alongside other approaches.

NIMH (National Institute of Mental Health) recognizes anxiety disorders as among the most common and treatable mental health conditions in the US, emphasizing that effective, evidence-based approaches are available.

Early recognition and appropriate support for anxiety are associated with better outcomes.

Common Drivers and Causes at the Population Level

Anxiety disorders arise from an interaction of biological, psychological, and social factors. No single cause applies to all people. Common contributors include:

Genetic and neurobiological factors: Anxiety disorders run in families, suggesting a genetic predisposition. Brain regions involved in threat detection and emotional regulation—including the amygdala and prefrontal cortex—show functional differences in people with anxiety disorders.

Stressful life events: Trauma, major life transitions, chronic stress from work or relationships, financial pressure, and loss are all associated with increased anxiety risk.

Chronic medical conditions: Thyroid disorders, cardiovascular disease, chronic pain, and other medical conditions can cause or worsen anxiety symptoms. This is an important reason for a medical evaluation when anxiety is new or worsening.

Medications and substances: Caffeine, stimulants, certain asthma inhalers, thyroid medications, and some over-the-counter decongestants can increase anxiety. Alcohol and benzodiazepine withdrawal also produce anxiety. Reviewing medications with a clinician is a useful step.

Sleep deprivation: Poor sleep and anxiety have a bidirectional relationship—each worsens the other.

Hormonal changes: Perimenopausal and postmenopausal transitions, thyroid fluctuations, and other hormonal changes can contribute to anxiety in some people.

Other mental health conditions: Depression and anxiety very commonly co-occur. A comprehensive mental health evaluation considers both.

What Follow-Up Evaluation May Be Considered

This section is general education. Clinical decisions are made based on individual history and circumstances.

The GAD-7 questionnaire: The GAD-7^[4] is a validated, seven-item questionnaire widely used in primary care to screen for generalized anxiety disorder. It asks how often over the past two weeks a person has been bothered by symptoms such as feeling nervous or on edge, uncontrollable worry, trouble relaxing, and feeling afraid that something awful might happen. Scores range from 0 to 21:

• 0–4: Minimal anxiety
• 5–9: Mild anxiety
• 10–14: Moderate anxiety
• 15–21: Severe anxiety

A score of 8 or higher is often used as a threshold prompting further diagnostic evaluation. As the USPSTF notes^[2], the GAD-7 performs well at detecting GAD and also has moderate accuracy for panic disorder, social anxiety, and PTSD.

Importantly, a high GAD-7 score is not a diagnosis—it identifies people for whom further evaluation by a clinician is warranted. Some people with high scores have anxiety disorders; some have other conditions that mimic anxiety.

Medical evaluation: A clinician will typically review the full history, rule out medical causes of anxiety (such as thyroid disorders, cardiac arrhythmias, or stimulant use), and consider a physical exam and relevant labs.

Mental health referral: Depending on severity and context, referral to a psychologist, psychiatrist, licensed clinical social worker, or therapist may be appropriate. Cognitive behavioral therapy (CBT) is the most evidence-supported psychotherapy for anxiety disorders.

Psychiatric evaluation: For moderate to severe anxiety or when anxiety co-occurs with other mental health conditions, psychiatric evaluation may be indicated.

Lifestyle and Prevention Factors the Evidence Supports

A 2024 systematic review and meta-analysis in PMC^[5] found that lifestyle interventions significantly reduced anxiety symptoms across diverse populations. The APA explicitly supports lifestyle factors as meaningful adjuncts to mental health care^[3], including:

Physical activity: Among the most well-evidenced non-pharmacological approaches for anxiety. Regular aerobic exercise is associated with reduced anxiety severity. Even moderate activity—walking, cycling, swimming—appears beneficial. The mechanism may involve modulation of stress hormones, neurotransmitter balance, and inflammation.

Sleep: Improving sleep quality has direct benefits for anxiety. Evidence-based sleep hygiene practices include consistent sleep and wake times, limiting caffeine after midday, minimizing screen exposure before bed, and creating a cool, dark sleeping environment.

Dietary patterns: While the evidence base is still developing, diets lower in ultra-processed foods and higher in vegetables, fruits, whole grains, and omega-3 fatty acids have been associated with lower rates of anxiety and depression in population studies.

Caffeine reduction: Caffeine is a known anxiogenic agent—it can trigger or worsen anxiety and panic symptoms, particularly at higher doses.

Alcohol reduction: While alcohol may feel calming initially, it disrupts sleep and is associated with increased anxiety, particularly during withdrawal. Reducing or eliminating alcohol is often recommended for people with anxiety.

Mindfulness and stress reduction: Mindfulness-based stress reduction (MBSR) and other mind-body practices have evidence supporting reduced anxiety. These approaches train attention and tolerance of discomfort.

Social connection: Social isolation is a risk factor for anxiety; maintaining meaningful relationships and social engagement is protective.

Questions to Bring to Your Appointment

Choose the questions most relevant to your situation:

• Does the pattern of my symptoms suggest an anxiety disorder, and if so, which type?
• Would a screening tool like the GAD-7 be useful to help characterize my symptoms?
• Are there medical causes of anxiety—like a thyroid disorder or another condition—that should be ruled out first?
• Could any of my medications or habits, like caffeine or alcohol, be contributing to my symptoms?
• What are the evidence-based treatment options for anxiety—both therapy-based and otherwise?
• What is cognitive behavioral therapy (CBT), and would it be a good fit for what I’m experiencing?
• How do I find a qualified therapist or mental health provider?
• What lifestyle changes would you prioritize for someone with anxiety symptoms?
• How do I know if my anxiety is affecting my health in ways I might not be noticing?
• Is what I’m experiencing consistent with general anxiety, or could it be panic disorder, social anxiety, or something else?
• If anxiety and depression are both present, how does that affect the evaluation and approach?
• What would be a good timeline and metric for knowing whether an intervention is working?

Red Flags Warranting Prompter Follow-Up

If you are in crisis—experiencing thoughts of self-harm or suicide—contact 988 (Suicide and Crisis Lifeline) or go to your nearest emergency room immediately.

Other situations that warrant more timely attention:

• Severe anxiety that is preventing you from leaving home, performing basic functions, or maintaining safety
• Panic attacks that are frequent, prolonged, or causing avoidance of daily activities
• New or sudden onset of severe anxiety without a clear precipitant—especially with physical symptoms that could suggest a cardiac or neurological cause
• Anxiety accompanied by significant depression, especially with hopelessness or passive suicidal thinking
• Anxiety that appears suddenly in the context of a new medication or substance change
• Anxiety so disabling that it is causing significant impairment at work, in relationships, or in self-care

Key Takeaways

• Anxiety disorders are among the most common mental health conditions in adults and are highly responsive to evidence-based treatment.
• The USPSTF recommends anxiety screening in primary care for adults under 65; the GAD-7 is a widely validated screening questionnaire—not a diagnostic tool—that helps clinicians identify people who may benefit from further evaluation.
• Common causes include genetic predisposition, chronic stress, trauma, medical conditions, medications, and lifestyle factors.
• Lifestyle factors—physical activity, sleep, dietary patterns, reduced caffeine and alcohol, and mindfulness practices—have evidence support as meaningful adjuncts to anxiety management.
• Medical causes should be considered and ruled out, including thyroid disorders and medication effects.
• Cognitive behavioral therapy (CBT) is the most evidence-supported psychotherapy; it is often combined with lifestyle approaches and, when indicated, medication management.
• If you are in crisis, contact 988 (US) or your local emergency services immediately.
