What health conditions can cause dizziness?

Dizziness can come from many different health conditions. Some are common and non-critical, while others may be more serious and require urgent care.

Many cases of dizziness are linked to conditions that, while uncomfortable, are not usually life-threatening. These include:

Inner ear disorders like benign paroxysmal positional vertigo (BPPV), vestibular neuritis, or Ménière’s disease
Vestibular migraine and other migraine-related dizziness
Medication side effects, such as from antibiotics, blood pressure medicines, or sedatives
Circulation changes like dehydration, anemia, or low blood sugar
Vision-related problems, including difficulty focusing or eye alignment changes
Anxiety or stress, which can trigger feelings of lightheadedness or imbalance

Some causes of dizziness may signal a medical emergency. Seek emergency care if dizziness is sudden, severe, or combined with symptoms such as:

Stroke or TIA (with slurred speech, numbness, weakness, or vision changes)
Heart conditions like arrhythmias or heart attack (with chest pain, palpitations, or shortness of breath)
Head trauma leading to sudden dizziness, confusion, or loss of consciousness
Serious infections with fever, severe headache, or neurological changes

If you are ever unsure whether your symptoms are urgent, call 911 or go to the nearest emergency department.
