Schwindel bei Asthma: Ein Zeichen schwerer Exazerbation

Dizziness is not a typical asthma symptom but can occur during severe attacks due to:

• Hypoxemia: Low blood O₂ from airflow obstruction → cerebral hypoxia.
• Hyperventilation: Rapid, shallow breathing blows off CO₂ → respiratory alkalosis → lightheadedness.
• Medication side effects: High-dose beta-agonists (albuterol) cause tremor, tachycardia, dizziness.
• Autonomic/neurological effects: Severe hypoxia affects brainstem.

If dizziness occurs during an asthma attack: It signals a potentially life-threatening exacerbation. Use rescue inhaler, call 911, seek emergency care immediately. Do not ignore.
