Lightheadedness can be described as feeling faint or dizzy. You may also feel like you could faint. For example, you might feel unbalanced or experience blurred vision. It is caused by standing up fast, dehydration, or low blood sugar levels.

What is the definition of lightheadedness?

The feeling of lightheadedness can be like you’re about to faint. Your body might feel heavy, and your head may not get enough blood. Another method to describe lightheadedness is a “reeling sensation.” Lightheadedness can be accompanied by blurred vision, as well as diminished balance.

While it’s not always a cause for concern, lightheadedness may be a sign of a medical issue and increase the risk of falling. Therefore, be cautious if you experience lightheadedness.

It is common for lightheadedness to occur whenever you swiftly move from a seated position to a standing position. This change in posture causes less blood flow to your brain. It may result in a drop in blood pressure which causes you to feel weak. It is more likely that you be affected by this condition if you suffer from dehydration due to an illness or a lack of intake of fluids. The sensation could improve if you lie down or sit down.

The feeling of lightheadedness can be accompanied by dizziness and nausea. Dizziness is the sensation of being unstable or unbalanced. Issues are usually caused in the inner ear, heart, brain, or the usage of certain drugs. 4 out of 10 individuals are experiencing dizziness so severe that they have to see the doctor. The risk of dizziness is that it alters your perception of balance and makes people more susceptible to falling.


A particular kind of dizziness, known as vertigo, is a cause of illusions that you feel like your surroundings are spinning or moving; however, in reality, they’re still. For example, vertigo could make you think you’re floating or swaying, tilting, or rotating. Most cases of dizziness can be due to inner ear problems that send signals to the brain that aren’t in line with the signs your eyes and nerves are receiving.

The causes of lightheadedness

Apart from dehydration and a change in the position, Other causes of lightheadedness are

  • allergies
  • altitude sickness

  • extremely deep or rapid breath (hyperventilation)
  • tension and stress

Certain medications, both prescription and over-the-counter, may also trigger lightheadedness.

In some cases, the reason for lightheadedness can be due to an even more serious issue such as:

  • heart diseases, such as heart attack or heartbeats that are in a rhythm that is not normal
  • Internal blood loss (in your organs, organ systems, or internal organs)
  • a shock that can cause a dramatic blood pressure drop

This is a summation. Seek medical attention if you suspect you need urgent care.
