Lightheadedness and dizziness normally go hand in hand, but feeling lightheaded is actually considered just one symptom of dizziness. For anyone that has experienced feeling lightheaded and fainting in the process, it can be quite scary. Thankfully, it’s normally not due to anything extremely serious. Of course, there are particular times, or other medical conditions, when it is actually the result of a more severe medical condition as well.
According to Dr. Lawrence Phillips, an assistant professor of medicine at New York University Langone Medical Center, fainting happens when the supply of blood to the brain lessens for a short period of time. He also explains, “The cause can stem from many different parts of the body, including a person’s blood pressure going down, heart rate going down, and from neurologic reasons independent of the heart. We try to find out why the blood pressure or heart rate would go down. Some of these reasons are common and not worrisome, but others need more evaluation.”
Others have described lightheadedness as a “reeling sensation,” along with a loss of balance or cloudy vision that feels like you’re about to faint. Oftentimes, it can also be accompanied by buzzing in the ears, overheating, sweating, partial blindness (explained as if you’re looking through a tunnel,) nausea and at times, even vomiting.
In order to better understand what it is all about, here are 16 causes of lightheadedness:
1. Standing Up Suddenly
One of the most common causes of lightheadedness is due to someone standing up too quickly. Interestingly, there is actually a term for this called orthostatic hypotension. The website mayclinic.org describes this as ‘a form of low blood pressure that happens when you stand up from sitting or lying down.’ Although most cases only last for a few minutes or less, when it doesn’t seem to go away, or it happens quite often, you need to get medical help to figure out the actual cause behind it.
