Tired? A sleep study might be in order

We’re almost a week into Daylight Saving Time and, for many people, the loss of sleep. The beginning of March, National Sleep Week, when sleep medicine professionals try to raise awareness about the causes and treatment of sleep disorders.

It’s still relevant today.

“There are various causes, emotional and physical, for the inability to get enough sleep,” said Dr.  Armand Wolff, medical director of the Center for Sleep Medicine at Bridgeport Hospital. “The leading physical cause of sleep deprivation is obstructive sleep apnea, which is characterized by the repeated interruption of breathing during sleep.”

Sleep apnea is caused when the muscles in the back of the throat fail to keep the airway open, Dr. Wolff explains. It disturbs sleep and can lead to low blood oxygen levels, which in turn can play a role in hypertension (high blood pressure), heart disease, and mood and memory problems.

Dr Wolff adds that many people associate sleep deprivation with insomnia, which affects, at some point in life, one in every two adults in the United States, making it the most common sleep complaint among Americans. Insomnia often stems from emotional stress or another medical condition. If untreated, insomnia can contribute to poorer overall health and a higher incidence of depression.

Sleepy during the day

Sleep apnea occurs in all age groups and both sexes, although the incidence of the disorder increases in people 40 and older. Smoking, alcohol consumption and being overweight also increase the risk of sleep apnea.

“Common signs of sleep apnea are sleepiness during the day, fatigue and snoring,” said Wolff. “Because most people do not realize that they snore, it is often a spouse or family member who prompts the sleep apnea patient to seek medical help.”

The most effective way to diagnose sleep apnea is with a medical test known as a sleep study, which can be done by trained professionals at a certified sleep center or in the patient’s own home. During a sleep study, breathing patterns, heart rate and other factors are carefully monitored by trained sleep technicians while the patient sleeps. The results of the study are evaluated by a sleep medicine physician and a course of treatment is prescribed.

The usual treatment for sleep apnea is continuous positive airway pressure (CPAP). CPAP is administered through a specially-fitted mask, and keeps the patient’s airway open during sleep. Some patients have difficulty adjusting to wearing the mask but newer models are smaller, and in some cases nostril tubes can be used.

Act soon

“If you or someone you know suspects that you have sleep apnea, please act soon,” Dr. Wolff urges. “Seek help at a certified sleep center so you can avoid the more serious medical problems and potentially harmful accidents that sleep loss can cause.”
