What is the cause to my dizziness?

Answer 1

Vertigo, sometimes called a headrush, is a major symptom of a balance disorder. It is the sensation of spinning while the body is stationary with respect to the earth or surroundings. With the eyes shut, there will be a sensation that the body is in movement, called subjective vertigo; if the eyes are open, the surroundings will appear to move past the field of vision, called objective vertigo. The effects may be slight. It may cause nausea or, if severe, may give rise to difficulty with standing and walking. Vertigo is usually associated with a problem in the inner ear balance mechanisms (vestibular system), in the brain, or with the nerve connections between these two organs. The most common cause is benign paroxysmal positional vertigo, or BPPV. Vertigo can be a symptom of an underlying harmless cause, such as in BPPV or it can suggest more serious problems. These include drug toxicities, strokes or tumors (though these are much less common than BPPV). Vertigo is typically classified into one of two categories depending on the location of the damaged vestibular pathway. These are peripheral or central vertigo. Each category has a distinct set of characteristics and associated findings. * Peripheral vertigo: The lesions, or the damaged areas, affect the inner ear or the vestibular division of the acoustic (CN VIII) nerve. Vertigo that is peripheral in origin tends to be felt as more severe than central vertigo, intermittent in timing, always associated with nystagmus in the horizontal plane and occasionally hearing loss or tinnitus (ringing of the ears). * Peripheral vertigo can be caused by BPPV, M

There is a skeletal muscle on the outer side of the eye ball called Lateral Rectus. If this muscle contracts (shortens) the eye ball would rotate outwards.

Suppose that we are looking at what is in front of us.

1. If our right Lateral Rectus muscle shortens we would be actually seeing what is there to our right.

2. If the right Lateral Rectus muscle contracts Isometrically then there would be no change in the length of the muscle and therefore we would still be seeing what is in front of us.

However, the Isometric contraction of the muscle would give us a feeling that we are seeing what is to our right.

If the right Lateral Pterygoid muscle contracts and relaxes repeatedly then we would get a feeling that what is there in front of us is moving to our right.

Thus, vertigo is caused by Isometric oscillation of the skeletal muscle called Lateral Rectus.

There are many causes of dizzieness. One is the common cold. Another is when you get a UTI (urinary tract infection). The flu is also another cause. If you have a head ache you also might get dizzy. The other cause is when you spin around and around right after you have eaten any tyoe of food. there are many more causes that i could list but i would have to go into detail so those are a couple of the many causes of dizzinesss.

Answer 4

Four out of ten adults consult their doctors for the symptom of dizziness, or vertigo. Dizziness may be caused by medications, ear infection, or a brain disorder. It can possibly be caused by anemia, Diabetes, or a deficiency in the thyroid, lack of vitamins, or the immune system. Your doctor will ask you when it happens, how often, how long, and are there any other accompanying symptoms.

Answer 5

There are any number of things that can cause vertigo: medications, alcohol, inner ear damage or damage to the pons (part of the brain stem).

Answer 6

Many health factors can contribute to dizziness. As the inner ear is directly connected with the body's proprioception, damage or inflammation of the ear can affect balance and dizziness.

Answer 7

The most common cause of BPV is head trauma (21% of cases) with a secondary concussion. The force of head trauma is thought to displace otolith particles in the semicircular canal.
