Obesity causes OSA or vice versa?
If a person is overweight and suffering from sleep-disordered breathing, he/she may
not be as motivated to exercise or to diet. When apnea leads to daytime sleepiness, it
may be that much harder to begin or sustain an exercise program, which has been
shown to help people begin or maintain weight loss

Assessment of
sleep stages
requires 3 studies
Electroencephalography :
monitor sleep stage
Electrooculography: monitor
both horizontal and vertical eye
movements.
Electromyography: record
atonia during REM sleep or lack
of atonia in patients with REM-
related parasomnias.
