Slumbered Sleep

To formally assess for sleep apnea, a person
may be asked to undergo a sleep evaluation
with a sleep specialist or may request an
overnight sleep study. A nightly sleep study
known as a polysomnogram is part of the
testing (PSG). In a sleep lab, a PSG is carried
out under the close supervision of a certified
technician. Numerous bodily processes that
occur at night while you sleep are monitored
during the test. Following the study, the severity
of the sleep apnea is assessed and the
number of occasions when breathing is hampered
while sleeping is recorded.
Losing weight can be advantageous for overweight
people. Most patients can have a reduction
in breathlessness episodes of even
10% with weight loss. However, uncorrected
obstructive sleep apnea can make it challenging
to lose weight since it can cause changes
in the metabolism and increased appetite.
