What causes dizziness and palpitations?

Dizziness and palpitations may result from a combination of various factors. Physiologically, chronic sleep deprivation, excessive fatigue, and high levels of mental stress can lead to sympathetic nervous system dysfunction, causing dizziness and palpitations. In terms of medical conditions, autonomic nervous system disorders, anemia, hypoglycemia, hypertension, arrhythmias, and hyperthyroidism may all trigger these symptoms. Additionally, side effects of certain medications—such as anti-anxiety drugs and antidepressants—can also contribute. When experiencing dizziness and palpitations, it is advisable to seek timely medical attention. A professional physician can conduct appropriate evaluations to determine the underlying cause and recommend suitable treatment measures to alleviate symptoms and maintain overall health.
