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
