Why do people faint? Fainting or syncope is when a person has a brief, sudden loss of consciousness. There are many reasons that can cause this decrease in blood to the brain, including, illnesses, deficiencies and traumas.
1. Illnesses – Heart problems like arrhythmia – Seizures – Hypoglycemia – Poor regulation of blood pressure – Parkinson’s disease – Peripheral autonomic neuropathy
2. Deficiencies – Anemia – Deficiency of Vitamin B-12
3. Traumas – Physical trauma, like a blow to the head – Mental trauma, like a shock
4. Dehydration – Dehydration causes blood pressure to drop – This stimulates the vagus nerve – The loss of just 1% to 2% of your body weight through dehydrating could cause fainting
5. Migraines – Can cause dizziness, either with or without headaches – Migraine-related vertigo may cause sensitivity to motion, light, and sound
6. Inner ear imbalance – Your inner ear contains otoconia – These are calcium and protein-based sensing crystals – If dislodged, they can float into inner ear’s canals – This triggers imbalance and syncope
7. Certain kinds of medication – Dizziness is a side effect of certain medicines – If your medication is causing dizziness, tell your doctor
