Dizziness can be caused by a variety of factors, including inner ear disturbance, motion sickness, and drug side effects. An underlying health issue, such as infection, poor circulation, or injury, can sometimes cause it. The symptoms of dizziness, as well as your triggers, can lead to plausible reasons. The duration of your dizziness, as well as any other symptoms you have, can help determine the cause.
Dizziness caused by inner ear disorders (vertigo)
The combined input from the many sections of your sensory system determines your sensation of balance. Among these are your:
Eyes that assist you in determining where your body is in space and how it is moving. Sensory nerves transmit information about body motions and postures to the brain. The inner ear has sensors that detect gravity and back-and-forth motion.
The sensation that your surroundings are spinning or moving is known as vertigo. With inner ear diseases, your brain receives inner ear signals that are inconsistent with what your eyes and sensory nerves are perceiving. Vertigo occurs while your brain attempts to sort out the chaos.
Benign paroxysmal positional vertigo (BPPV).
This illness causes a brief yet severe sensation of spinning or movement. These episodes are caused by an abrupt change in head movement, such as turning over in bed, sitting up, or being knocked on the head. BPPV is the most common cause of dizziness.
Infection.
Vestibular neuritis, a viral infection of the vestibular nerve, can produce severe, continuous vertigo. You may have labyrinthitis if face sudden hearing loss.
Meniere’s disease.
This condition can cause an excessive buildup of fluid in your inner ear. It is distinguished by brief episodes of vertigo that might last for several hours. You may also have variable hearing loss, ringing in the ears, and the sensation of one ear being blocked.
Migraine.
Migraine sufferers may experience vertigo or other types of dizziness even when they do not have a severe headache. Such dizziness episodes can last minutes to hours and are often accompanied by headaches and sensitivity to light and noise.
