Dizziness is a condition in which the body feels as if it is going to lose balance when you stand up suddenly or turn your head. In medicine, it is called Vertigo or Dizziness. It is not a specific disease, but a symptom that indicates problems in some other organs in the body. Here are the 5 main scientific causes behind severe dizziness:
Problems in the inner ear (BPPV & Vertigo): Our body’s balance is maintained by the fluids and small calcium granules (Otoliths) in the inner ear. When we move our head suddenly, these calcium granules start moving from their position. This is called BPPV (Benign Paroxysmal Positional Vertigo). It causes severe dizziness and vomiting by sending incorrect messages to the brain.
Blood Pressure Variations: A sudden drop in blood pressure (Hypotension) or a sudden rise in blood pressure (Hypertension) can cause dizziness. Blood flow to the brain is temporarily reduced, especially when you get up suddenly from a lying or sitting position. This is called Orthostatic Hypotension.
Anemia and Anemia: When the hemoglobin level in the body decreases, the blood is unable to carry enough oxygen to the brain cells. This can result in chronic dizziness, sudden blackouts, extreme fatigue, and excessive palpitations.
Dehydration and Low Blood Sugar: When you do not drink enough water, the blood volume in the body decreases, which affects blood flow to the brain. Also, when you do not eat for a long time, the blood sugar level suddenly drops (Hypoglycemia / Low Sugar) can cause severe dizziness.
Migraine and neck degeneration: Dizziness is a major symptom in people with severe migraines (Vestibular Migraine). Dizziness can also be experienced when there is pressure on the blood vessels leading to the brain due to degeneration of the vertebrae in the neck (Cervical Spondylosis).
