Not everyone who suffers from insomnia should routinely have a polysomnography study to screen for sleep disorders, but it may be indicated for those with risk factors for sleep apnea, including obesity, a thick neck diameter, or fullness of the flesh in the oropharynx. For most people, the test is not needed to make a diagnosis, and insomnia can often be treated by changing their schedule to make time for sufficient sleep and by improving sleep hygiene.
