What is lightheadedness?
Lightheadedness is a term that describes the sensation of being near fainting or losing consciousness. It can affect your vision, hearing, and coordination. It can also make you feel nauseous, sweaty, or pale.
Lightheadedness usually occurs when you stand up quickly from a sitting or lying position. This sudden change in posture can cause a drop in blood pressure, which reduces blood flow to your brain. This can create a temporary lack of oxygen and nutrients to your brain cells, which can make you feel faint.
Lightheadedness often lasts for a few seconds or minutes and goes away when you sit or lie down again. However, some people may experience more frequent or severe episodes of lightheadedness that interfere with their daily activities and quality of life.
