Dizziness can have many causes, often related to how the brain receives balance information or blood flow. Common reasons include inner ear problems such as benign paroxysmal positional vertigo (BPPV), vestibular migraines, or Meniere's disease. Reduced blood flow to the brain due to low blood pressure, anemia, dehydration, hypoglycemia (low blood sugar), or heart rhythm issues can also cause dizziness. Certain medications like antidepressants, sedatives, or blood pressure medicines may have dizziness as a side effect. Other factors include anxiety, overheating, motion sickness, or infections affecting the vestibular nerve. Because dizziness has diverse causes ranging from minor to potentially serious, persistent or recurrent dizziness should be evaluated by a healthcare professional to identify the specific cause and appropriate treatment.
