You should see a doctor about anxiety when it persists for more than 6 months, interferes with daily functioning, or causes physical symptoms you can't control. According to the National Institute of Mental Health, only 36.9% of people with anxiety disorders receive treatment — yet anxiety is among the most treatable mental health conditions, with success rates of 60-90%.
Signs It's Time to See a Doctor
The Mayo Clinic recommends seeking medical attention when:
- Duration: Excessive worry lasting most days for 6 months or more
- Impact: Anxiety interferes with work, school, or relationships
- Control: You feel unable to control your worrying
- Avoidance: You're avoiding places, people, or activities because of fear
- Physical symptoms: Persistent insomnia, digestive issues, heart palpitations, or muscle tension
- Panic attacks: Sudden episodes of intense fear with chest pain, shortness of breath, or feeling of impending doom
- Self-medication: Using alcohol, cannabis, or other substances to manage anxiety
- Co-occurring depression: Persistent sadness, hopelessness, or loss of interest alongside anxiety (learn more about depression)
See a Doctor Immediately If
Some anxiety symptoms require urgent medical evaluation:
- Chest pain or difficulty breathing (rule out cardiac causes)
- Suicidal thoughts or self-harm urges — call 988 (Suicide & Crisis Lifeline)
- Anxiety so severe you cannot leave your home
- Sudden onset of severe anxiety with no history (may indicate a medical condition)
- Symptoms after starting a new medication
Medical Conditions That Mimic Anxiety
Your doctor will want to rule out physical causes. Several conditions produce anxiety-like symptoms:
- Hyperthyroidism — overactive thyroid causes racing heart, nervousness, trembling
- Heart arrhythmias — palpitations and chest tightness
- Hypertension — can cause anxiety-like physical symptoms
- Blood sugar fluctuations — especially in diabetes
- Respiratory conditions — shortness of breath triggers panic
- Medication side effects — stimulants, corticosteroids, some asthma medications
- Caffeine excess or withdrawal
A basic workup typically includes thyroid function tests, basic metabolic panel, and sometimes an EKG.
What to Expect at Your Appointment
Knowing what to expect can reduce anxiety about the visit itself:
- Symptom discussion: When symptoms started, how often they occur, what triggers them
- Screening questionnaire: Usually the GAD-7 (7 questions, takes 3 minutes)
- Medical history: Family history of anxiety/depression, current medications, substance use
- Physical exam: Vitals, thyroid check, basic neurological screening
- Treatment discussion: Options based on severity and your preferences
Pro tip: Write down your symptoms, their frequency, and questions before the appointment. It's easy to minimize symptoms or forget details when you're in the office.
Treatment Options Your Doctor May Recommend
The APA Clinical Practice Guideline recommends these evidence-based treatments:
- Cognitive Behavioral Therapy (CBT): First-line treatment, 60-80% response rate. Typically 12-16 sessions.
- SSRIs/SNRIs: Medications like sertraline, escitalopram, or venlafaxine. Usually take 4-6 weeks for full effect.
- Combined approach: Therapy + medication shows the highest success rates for moderate-to-severe anxiety.
- Lifestyle modifications: Exercise, sleep hygiene, stress management, caffeine reduction.
Recovery is not instant, but it is typical. Most people see significant improvement within 8-12 weeks of starting treatment. The key is starting — anxiety disorders don't typically resolve without intervention, and early treatment prevents complications like depression, chronic insomnia, and substance misuse.
