Fainting (a brief loss of consciousness) occurs when there is reduced blood flow and oxygen delivery to the brain. Here are five causes of fainting your should know.
Dehydration
Dehydration in the body can lower blood pressure and result in fainting, especially in hot weather or after vigorous exercise.
Low blood sugar
The symptoms of low blood sugar include weakness, lightheadedness, and eventually fainting. People with diabetes who over-inject insulin or skip meals experience this.
Heart problems
Due to reduced blood supply to the brain, certain cardiac disorders, such as arrhythmia, heart valve issues, or other structural anomalies, can make a person feel dizzy.
Neurological Conditions
Fainting can be brought on by neurological conditions like seizures, migraines, or Parkinson's disease because they interfere with the brain's regular operation.
Anaemia
Dizziness and fainting are symptoms of anaemia, a disease where the body doesn't have enough red blood cells (RBC) to transport oxygen to the brain and other organs.
Conclusion
See a doctor if you experience fainting or near-fainting episodes because they may indicate a serious medical condition that needs to be treated.
