Vertigo is a feeling that you or your surroundings are moving when
there is no actual movement. The feeling of motion is commonly described as
spinning or whirling, but it may also include sensations of falling or tilting.
It may be difficult to walk or stand, and you may lose your balance and
fall.
Mild vertigo occurs occasionally for a brief
time and goes away on its own. Nausea, but not vomiting, also may be present.
Mild vertigo or lightheadedness that comes and goes without other symptoms
usually is not a serious problem. It can occur with other illnesses such as a
cold, the flu, or other viral infections. This type of vertigo usually clears
up when the viral illness goes away.
Moderate vertigo requires that you lie down,
lie still, and not move your head in order to stop the feeling of movement.
Nausea is present and you may vomit occasionally, but you are able to keep
fluids down.
Severe vertigo occurs when the feeling of
movement is continuous, even when lying down. Nausea and vomiting are so severe
that you will vomit most of the fluid you drink. This may lead to
dehydration. Severe vertigo with persistent vomiting
usually requires evaluation by a health professional.
Sudden vertigo that begins with new ringing in the ears (tinnitus) or
hearing loss can indicate a problem that requires a visit to a health
professional, such as
Ménière's disease or
labyrinthitis.
Contact your health professional if persistent vertigo keeps you from
participating in your usual daily activities. This type of vertigo may indicate
a condition such as
benign paroxysmal positional vertigo (BPPV) or
vestibular neuritis.
If a serious illness is causing the vertigo, other symptoms in
addition to the vertigo usually are present or will develop quickly. Vertigo
that occurs with any
signs of a serious illness requires immediate medical
treatment.
When vertigo is sudden or severe, interferes with your daily
activities, or occurs with other severe symptoms, an evaluation by a health
professional is required immediately.
