Benign Positional Vertigo (BPV) — the name is a mouthful, but it
conveys a lot of information. A mild, if very annoying condition,
BPV is truly benign. The symptoms are brief and intermittent, and
they are invariably triggered by a change in head position. And
the main symptom is true vertigo.
BPV is the most common form of vertigo. It can strike people of
all ages, but it typically targets those over 50. In BPV,
dizziness is triggered by head motions such as turning over in
bed, getting in or out of bed, bending over or straightening up,
or craning the neck to look up. The vertigo may be severe, but it
is short-lived, usually resolving in 15 seconds or less.
Doctors can suspect BPV on the basis of its characteristic
symptoms, and they can confirm the diagnosis with a simple test,
the Hallpike-Dix maneuver. You'll be asked to sit on an exam
table with your head turned 45 degrees to the side. Then you'll
be tilted back so your head is hanging off the table. Your doctor
will hold your head to one side for 30–60 seconds, then repeat
the process with your head turned 45 degrees to the other side.
If you feel dizzy during the test and your doctor detects a
characteristic movement of your eyes called nystagmus, the
diagnosis of BPV is established, and you won't need additional
Use the Heimlich maneuver when someone is choking on something
and cannot cough or speak — that means the person cannot breathe.
Another sign is if the skin begins to turn blue. In these
circumstances, the Heimlich maneuver can be lifesaving. Here's
how to do it.
For an adult who is standing or sitting:
As we get older, our balance tends to diminish. Exercise, in addition to its many other benefits, can help regain or maintain balance and control.
If a person who is choking is still able to speak, their airway does not have a significant obstruction, so the Heimlich maneuver should not be performed.

patients recover more quickly, even if they are not yet ready to

A fruit-rich diet appears to help protect against colorectal

Cigars are not typically smoked as frequently as cigarettes are,
but the chemicals emitted in their smoke are more dangerous than
