Can Anxiety Make You Dizzy? Yes — Here's Why, and What Else It Could Be

How does anxiety cause dizziness?

Anxiety triggers the body's fight-or-flight response. Several of the changes that response sets in motion can produce dizziness 1Ref 1National Institute of Mental Health (2023).Anxiety Disorders.Anxiety's physical symptom profile including the fight-or-flight response, hyperventilation, and heightened body awareness as mechanisms behind anxiety-related dizziness:

Hyperventilation: When anxious, people often breathe faster and more shallowly than they realize. This reduces carbon dioxide levels in the blood — a state called hypocapnia — which causes blood vessels to constrict and can produce lightheadedness, tingling in the hands or face, and a floating or disconnected sensation.

Muscle tension: Anxiety causes the muscles of the neck and shoulders to tighten. The muscles and joints of the neck play a role in balance signaling to the brain; tension here can contribute to feelings of unsteadiness.

Changes in blood pressure: The cardiovascular effects of anxiety — including rapid heart rate and fluctuating blood pressure — can affect cerebral blood flow and create a lightheaded feeling.

Heightened body awareness: Anxiety amplifies attention to body sensations. A mild, normal fluctuation in balance or perception that most people would not notice can feel alarming and pronounced when anxiety is high 1Ref 1National Institute of Mental Health (2023).Anxiety Disorders.Anxiety's physical symptom profile including the fight-or-flight response, hyperventilation, and heightened body awareness as mechanisms behind anxiety-related dizziness.

What does anxiety-related dizziness feel like?

Anxiety-related dizziness tends to have certain characteristics:

• Lightheadedness or a floating, "not quite here" feeling rather than a spinning sensation (vertigo)
• Often accompanied by other anxiety symptoms: racing heart, tight chest, shortness of breath, sweating, or tingling
• Comes on during or after a stressful situation, a panic attack, or a period of heightened worry
• May improve when breathing is slowed deliberately
• Tends to come and go with anxiety levels

This is a general pattern, not a rule. Some people with anxiety do experience spinning-type dizziness. And some people first notice the dizziness and only later connect it to anxiety.

What other causes of dizziness need to be considered?

Dizziness is one of the most common symptoms a person can experience, and it has a wide range of causes beyond anxiety 2Ref 2DeGeorge KC, Grover M, Streeter GS (2022).Generalized Anxiety Disorder and Panic Disorder in Adults.Physical symptoms of anxiety including dizziness and lightheadedness; importance of ruling out other causes before attributing dizziness to anxiety:

Inner ear conditions: - BPPV (benign paroxysmal positional vertigo): The most common cause of true spinning vertigo — caused by displaced calcium crystals in the inner ear, often triggered by head movements - Vestibular neuritis and labyrinthitis: Inner ear inflammation that can cause intense dizziness lasting days - Meniere's disease: Episodic vertigo with ringing in the ears and hearing changes

Cardiovascular causes: An irregular heartbeat (arrhythmia) or other cardiac issue can cause dizziness. This is a more serious cause that warrants evaluation if dizziness is prominent or accompanied by palpitations.

Dehydration and orthostatic hypotension: Standing up quickly and feeling dizzy is common, especially in people who are dehydrated or on certain medications.

Anemia or low blood sugar: Both cause lightheadedness and are simple to check with blood work.

Medication side effects: Blood pressure medications, certain antidepressants, and antihistamines can cause dizziness.

Neurological causes: Dizziness with sudden vision changes, weakness, difficulty speaking, or loss of coordination can signal a serious problem and warrants immediate evaluation.

How does a clinician evaluate dizziness?

A clinician will take a thorough history, paying attention to what the dizziness feels like (spinning versus floating), what triggers it (head movements, standing up, stress), how long it lasts, and what other symptoms accompany it. Physical examination, including checking blood pressure in different positions and a basic neurological check, is standard.

Selected tests may follow: blood pressure in different positions, basic bloodwork (CBC, glucose), the Dix-Hallpike maneuver to check for BPPV, an EKG if cardiac arrhythmia is a concern, and hearing assessment if inner ear involvement is suspected.

The goal is to rule out treatable physical causes before attributing dizziness to anxiety 2Ref 2DeGeorge KC, Grover M, Streeter GS (2022).Generalized Anxiety Disorder and Panic Disorder in Adults.Physical symptoms of anxiety including dizziness and lightheadedness; importance of ruling out other causes before attributing dizziness to anxiety. And even if anxiety is contributing, treating anxiety alone will not help if there is also an inner ear condition.

If anxiety is identified as a cause, effective treatments are available 3Ref 3Hofmann SG, Asnaani A, Vonk IJJ, Sawyer AT, Fang A (2012).The Efficacy of Cognitive Behavioral Therapy: A Review of Meta-analyses.Effective treatments available for anxiety disorders, which can in turn reduce anxiety-related physical symptoms including dizziness. The US Preventive Services Task Force also recommends routine anxiety screening for adults, recognizing how frequently anxiety goes unidentified 4Ref 4US Preventive Services Task Force (2023).Screening for Anxiety Disorders in Adults: US Preventive Services Task Force Recommendation Statement.USPSTF recommendation for routine anxiety screening in adults, recognizing how frequently anxiety goes unidentified.
