The causes of dizziness vary tremendously and can be a result of a simple issue or a very complicated problem. Dizziness, also referred to as vertigo, is a feeling that a person’s surroundings are moving when they really aren’t. Dizziness can lead to falls if a person isn’t careful when feeling this sensation.
Dizziness is the feeling that the surroundings around you are moving. This varies from lightheadedness, which is a feeling that you are about to faint. Vertigo is a technical term used to describe dizziness. A person experiencing this feels as though she is spinning, whirling, falling or tilting. If you experience extreme vertigo, you may not be able to walk or stand. Vertigo occurs when a conflict between the brain and the sensory systems of the body takes place.
Inner Ear Problems
Problems within the inner ear often cause dizzy spells or dizziness in general. The inner ear has a balance mechanism that if affected may cause dizziness. Several common inner ear issues that lead to dizziness are benign paroxysmal positional vertigo, ear infections and Meniere’s disease, which is when a large buildup of fluid is stuck in the inner ear. Labyrinthitis is another ear disorder that causes dizziness. This occurs when there is swelling inside the inner ear. People with this disorder generally experience a sudden loss of hearing; it usually occurs after the person had a cold or flu virus.
Reduced Blood Flow
If your brain does not receive enough blood, dizziness often occurs. This is due to many different causes including dehydration, strokes and arteriosclerosis, a stiffening of the arteries. Whenever a decrease of blood flow occurs through the arteries, dizziness may occur. Other possible causes are problems with heart circulation and irregular blood flow. It could also be from high or low blood pressure. Someone standing up too quickly may feel dizzy for a moment after eating a large meal or sitting for a while.
Brain tumors and cancer may cause dizziness in a person. Although these are less common causes of dizziness, they are possible options. Another cause is if there is a noncancerous growth behind the eardrum called cholesteatoma. Head or ear injuries often cause dizziness in many people as well as anxiety or panic attacks. Other causes may be dehydration, motion sickness from amusement park rides and migraine headaches.
