There are several issues which make people faint. Older people, particularly aged over 65-years of age usually faint due to low blood pressure levels. Dehydration is another health issue which makes people faint. In this, the amount of fluid in your blood is significantly reduced and blood pressure decreases. Diabetic people urinate frequently which eventually leads to dehydration. Fainting also occurs due to heart diseases which interfere with the brain’s blood supply.
