Various parts or organs of yours work together in keeping you balanced. They include your brain, spine, eyes, inner ear and nerves situated in your feet. Any one of them that goes haywire can leave you feeling dizzy — that uncomfortable sensation that you or the world around you is spinning.
Sometimes dizziness goes away on its own after a while or as soon as the problem with your balance gets resolved. In some instances, it can be a telltale sign of something serious taking place inside your body.
Dizziness can put you in danger in that it can make you lose your balance, and you may hit your head. In the elderly, falling can easily lead to fractures especially if osteoporosis is present.
In some instances, all you have to do when you feel dizzy is lie down until the uncomfortable sensation goes away. Doing so can also keep you from falling and incurring an injury. However, there are times in which immediate medical attention is warranted. This is especially true if dizziness is accompanied by symptoms such as a terrible headache, numbness in the face, change in speech or vision, weakness in the leg or arm, chest pain, shortness of breath and a stiff neck.
According to doctors, the following are some of the most common causes of dizziness:
If you feel that you are spinning or everything else is moving around you especially when you move your head, it’s very much likely that what you are experiencing is what’s called vertigo.
Oftentimes, vertigo is a problem that concerns the inner ear — tiny fluid-filled canals in your inner ear may collect bits of hardened calcium, and such can cause the wrong signals to be sent to your brain. Often, this is caused by the aging process although head traumas or injuries can be blamed for it, too.
Vertigo may also be caused by an infection in the inner ear. Such is referred to as labyrinthitis or vestibular neuritis. More often than not, it is due to virus. However, bacteria in the middle ear can be held accountable for it at times.
Dizziness that is due to an inner ear infection usually appears suddenly, and it is often accompanied by tinnitus — a ringing or buzzing in the ear. It’s not unlikely for you to also encounter an earache and a fever. If it’s bacterial, antibiotics may be given by a doctor. If it’s viral, it will go away on its own although there are drugs available for managing the symptoms.
Earlier, it was mentioned that there are fluid-filled canals in the inner ear. Abnormality in the amount of fluid in the said canals or problem with the inner ear structure can lead to what’s known as Meniere’s disease.
People who suffer from Meniere’s disease often encounter attacks that can last anywhere from 2 to 4 hours. During an attack, the person experiences vertigo, tinnitus, nausea, sweating and even irregular heartbeat. Some people with Meniere’s disease may also have hearing loss during an attack or for good.
There are instances in which it is decreased circulation to the brain that can be blamed for dizziness. This can deprive the brain of much-needed oxygen, causing the individual to become lightheaded and even faint.
Sometimes it is a sudden drop in the blood pressure that can cause a decrease in the supply of blood to the brain such as when going from a seated to a standing position. There are problems regarding the cardiovascular system that can be the culprit, including hypotension, arrhythmia or irregular heartbeat, blood clots, arterial clogging and heart failure.
In some cases, poor circulation too the brain is not the fault of the cardiovascular system but the individual who is feeling dizzy, in particular if he or she fails to consume plenty of water.
Dehydration can cause the blood pressure to drop, and this can decrease the supply of oxygen to the brain. Lack of fluid in the body is likely to be the culprit if dizziness is accompanied by feeling of thirst, mouth dryness, fatigue and dark-colored urine. Needless to say, the individual should increase his or her water intake.
