Dizzy spells can be caused by a variety of factors, often related to problems with balance, blood flow, or other underlying health conditions. Common causes include:
- Inner Ear Problems:
- Benign paroxysmal positional vertigo (BPPV): caused by loose particles in the inner ear that disrupt balance.
- Meniere's disease: fluid buildup in the inner ear leading to vertigo and hearing issues.
- Vestibular migraine: dizziness associated with migraine attacks.
- Vestibular neuronitis or labyrinthitis: inflammation of inner ear nerves often caused by viral infections.
- Circulatory Issues:
- Reduced blood flow to the brain from arteriosclerosis, anemia, or heart problems.
- Orthostatic hypotension: a sudden drop in blood pressure when standing up quickly.
- Hypoglycemia (low blood sugar).
- Medication Side Effects:
- Dizziness can be a side effect of antidepressants, anti-seizure drugs, blood pressure medications, sedatives, and tranquilizers.
- Other Causes:
- Dehydration or overheating.
- Anxiety, panic attacks, and stress.
- Carbon monoxide poisoning.
- Motion sickness.
- Concussion or head injury.
- Nutritional deficiencies.
Dizziness may feel like lightheadedness, spinning (vertigo), or loss of balance, and each sensation may point to different causes. For an accurate diagnosis and appropriate treatment, consulting a healthcare professional is important. If dizziness occurs suddenly, is severe, or accompanied by other symptoms like fainting, confusion, or chest pain, immediate medical attention is advised.
