It occurs when you lose consciousness for a short period because your brain is not getting enough oxygen.
The feeling of lightheadedness is similar to faintness, dizziness, or being on the verge of fainting.
A sensation of movement or spinning in the surroundings
The state of giddiness occurs when one loses balance as a result of whirling and swirling around.
