Vertigo - What Can Cause It?

Vertigo is marked by a feeling of dizziness and disorientation. This feeling could be so bad that even standing up makes a person feel lightheaded. Vertigo can even make a person feel nauseous.

The five most common causes of vertigo are:

1. Meniere’s disease: Meniere’s disease is a condition that affects the inner ear. It is marked by a buildup of fluid in the inner ear as a result of a viral infection, allergies or an injury to the ear. Along with dizziness, it can also cause a ringing noise in the ears, the feeling of having plugged ears and hearing loss. Vertigo caused by Meniere’s disease can last for months.
2. Benign Paroxysmal Positional Vertigo (BPPV): This is one of the most common triggers of vertigo. This condition is caused by small crystals that break free and float in the inner ear canals. These canals are known as semicircular canals. Vertigo caused by BPPV is usually short-lived and relieves itself is a few minutes. Moving the head in a certain way or jerky movements can trigger vertigo in such cases. The exact cause of this condition is not clear but it has been often associated with severe head trauma.
3. Labyrinthitis: This condition is also known as vestibular neuritis. It is marked by swelling and irritation of the two vestibular nerves in the inner ear canal. Labyrinthitis may be caused by a viral infection or an inner ear infection. In such cases, vertigo may be accompanied by hearing loss. Older adults are at the highest risk of this condition.
4. Vitamin B12 Deficiency: A simple vitamin deficiency can also cause vertigo and dizziness. Vitamin B12 helps prevent anaemia and keeps nerves and blood cells healthy. Low levels of this vitamin can cause neurological problems that in turn cause vertigo. This is because vitamin deficiencies reduce blood pressure and blood flow to the brain. A simple blood test can help check Vitamin B1 levels and identify a deficiency. Some of the best sources of vitamin B12 are dairy products, meats and fortified cereals.
5. Dehydration: 60% of the human body mass is water. Water plays a number of roles in the human body. One of the most important functions of water is the circulation of nutrients in the body and blood flow. Thus, even mild dehydration can make a person feel dizzy and nauseous. This type of vertigo may be relieved by drinking copious amounts of fluids.
