Fainting

We look into all the causes of fainting that can indicate a serious health concern.

The reasons for fainting are vast, and it can often be difficult to find the cause. From low blood sugar and dehydration to heart complications and seizures, some causes of fainting aren't serious, while others can be extremely dangerous. Because it’s possible for a serious health condition or disease to cause fainting, it’s important to see your doctor or, in some situations, seek emergency medical treatment immediately.
