Nearly everybody has experienced dizziness caused by rapid body movement, however sudden chronic unexplained dizziness can be alarming. Dizziness can be caused by several things and the effects brought on by episodes of dizzy spells can range from unsteadiness issues to vertigo or sensations of the room spinning, nausea and vomiting.
A major portion of the system, which contributes to maintaining a person’s balance is located in the same region as hearing. The hearing mechanism is divided into three parts, the outer, middle and inner ear. Inside the inner ear is the spiral “seashell” looking organ of hearing called the Cochlea. At the top of the cochlea there are three loops called the semi-circular canals, which are connected to the cochlea through the vestibule and these organs are filled with fluid. When the fluid pressure changes and it affects the other parts. The three semi-circular canals and the vestibule are specifically connected to a person’s equilibrium.
The vestibule has two chambers containing nerve endings, which can detect the head as it relates to gravity. The nerve endings basically help detect the speed, direction and movement. This all simply means that when a person walks or moves the brain receives all kinds of messages from different parts of the body including both sets of semi-circular canals and vestibules.
Dizziness can result however from many different stimuli or medical problems such as mastoid disease. Outer and Middle ear infections can if left untreated affect the inner ear and mastoid. Dizziness can be a symptom therefore caused by a chronic untreated ear infection.
Another medical reason for dizziness can be circulatory in nature. Postural hypotension is one of the major causes for dizziness and unsteadiness issues especially in older adults. A person may get up so quickly that his blood pressure falls rapidly and therefore makes him unsteadiness, however the dizziness may not last but a short time. Most seniors and older adults are on blood pressure medications and if arising quickly they may have a rapid drop in blood pressure causing them to be unsteady and dizzy until their blood pressure equalizes. One of the tips for this feeling is to arise more slowly from a sitting or lying position. Chronic dizziness on arising must however be evaluated by your physician at all times. In many cases blood pressure medications may need to be adjusted.
Other causes for dizziness can be emotional distress, fatigue, medication reactions, body’s chemistry, arteriosclerosis or head injuries. If you are experiencing any dizzy spells you should see your physician to be properly evaluated, diagnosed and treated. In many cases some medications can help you with dizziness problems and proper diagnosis of the cause of the dizziness is vital.
