Do
you sometimes feel somewhat dizzy in a way that you or your environment seems
to be spinning? The feeling of spinning or falling through space when, in
fact, there is no motion?
Well,
you might be suffering from vertigo; a subtype of dizziness in which a
patient inappropriately experiences the perception of motion (spinning,
tumbling, falling forward or backward, or the ground rolling beneath one’s feet
) due to dysfunction of the vestibular system.
The
vestibular system detects
motion of the head in space and in turn generate reflexes that are crucial for
our daily activities, such as stabilizing the visual axis (gaze) and
maintaining head and body posture. In addition, the vestibular system provides
us with our subjective sense of movement and orientation in space. The
vestibular sensory organs are located in the petrous part of the temporal bone
in close proximity to the cochlea, the auditory sensory organ.
Hence,
when a dysfunction of the vestibular system occurs, the affected
person may experience vertigo and describe an illusion of movement which is
often associated with nausea, vomiting, sweating as well as a balance
disorder which causes difficulty in standing or walking.
In
addition, it may be difficult to focus visually, feel disoriented and
find it uncomfortable to keep the eyes open during vertigo spells which
may last from a few minutes to days, depending on the cause.
Vertigo
is not limited to adults alone; it may be present at any age. Its
prevalence rises with age and is about two to three times higher in women
than in men. It is approximated that 2-3% of emergency department visits
is due to vertigo attacks.
Note
that vertigo shouldn’t be confused with motion sickness; which involves that
feeling of being off-balance and lacking equilibrium, usually caused by
repeated motions such as riding in a car or boat.
Beware
of repetitive spinning (as in familiar childhood games), or unfamiliar
movements (e.g., when the head is held in an unusual position for an extended
period) which can induce short-lived vertigo by disrupting the inertia of the
fluid in the vestibular system; otherwise known as physiologic vertigo.
It is usually easily corrected though; either by moving the head and neck into
a more normal position or focusing on an external reference point to give the
vestibular system an opportunity to stabilize.
It
is possible for those symptoms to be constant or episodic and may be due
largely to a movement or change in position.
Check
it out; when you feel like you yourself are moving, it’s called subjective
vertigo. When it seems like your surroundings or objects in your
surroundings are moving, then that is called objective vertigo. When
you feel an intensive sensation of rotation inside your head, that could be
pseudovertigo.
When
should you seek medical care?
Any
signs and symptoms of vertigo deserves an evaluation by your doctor to rule out
potentially serious or life-threatening causes. Although the majority of
cases of vertigo are harmless, it can also be debilitating, as vertigo can be
caused by problems in the brain or the inner ear which are very sensitive
organs. Fortunately, most causes are easily treated with prescription
medication.
When
you show certain signs and symptoms listed below, it may require
evaluation in a hospital’s emergency department:
- have double vision or other visual disturbances
- have difficulty speaking
- show abnormal eye movements
- has a throbbing headache
- has feelings of weakness
- have hearing loss and a ringing sensation in the ears
- have difficulty in walking or controlling your arms and legs
- have altered level of consciousness, is acting inappropriately
It
is necessary to tell the doctor if you or a patient has had any recent
head trauma or whiplash injury as well as any new medications being taken
recently, as these may have some bearing on diagnosis. Seeking a medical
professional’s expertise is relevant because sometimes vertigo is a sign of a
serious health condition like stroke.
One
doctor friend gave me these tips to prevent vertigo spells - “Do not
jump out of bed in a hasty manner upon waking up nor bend
suddenly. meaning, refrain from fast or sudden body
movements. Get up slowly after lying down or sitting for an extended
period, instead of standing right up. When you need to really turn your head to
look in a different direction, do so in a controlled and slow manner.
Getting
dizzy isn’t always an “it’s nothing.” So watch out for your self-preservation.
Don’t get dizzy! Don’t allow that vertigo … to
set itself into your life.
