Wharton (259 -0979)

Sleep Deprivation l Disasters: Exxon Valdez, Challenger Space Shuttle, Chernoble Nuclear Plant l 33% of fatal truck accidents l 10% of fatal car accidents l Impairment the same whether: drunk, sleep deprived (<4 -6 hrs. ), sleep apnea l Must be taken seriously: sleep 8 hours l Leads to obesity

Chronic Insomnia l Acute Insomnia (<4 weeks): stress, illness l Chronic Insomnia: >4 weeks, often years l Treat basic problem: 50% psychological l Treat primary insomnia, begins childhood l Psychotherapy and behavioral therapy l Medications, new ones coming out l PCP, Psychologists, Psychiatrists

Sleep Apnea: Risk Factors l Family history l Obesity: 80 % of sleep apnea patients l Increasing age l Male gender l Large tonsils / adenoids l Small mandible, large neck l Smoking, alcohol, sedatives

Sleep Apnea: Consequences l Social / Psychological: work, family l Personal: fatigue, tired, depression, irritability, impotence, memory l More accidents: work home motor vehicle l Higher death rates with severe apnea l Hypertension, Congestive Heart Failure l Associated: Heart Attacks, Strokes, A Fib l Promotes obesity and diabetes

Obstructive Sleep Apnea What is OSA? • Cessation of airflow with ongoing respiratory effort • Normal Snoring Sleep Apnea

Sleep Apnea: Treatment l Behavioral: Weight Loss, Sleep Position (Sleep on side, head raised), Oxygen, Avoid sedatives and alcohol l CPAP: proven therapy, needs motivation: widely available l Surgery: tracheostomy, tonsillectomy, pull forth mandible or tongue l Dental appliances: also pull forth mandible or tongue; expertise necessary

Treatment Options Treatment -CPAP treatment – Positive pressure maintains airway patencey – Titration – 100% effective CPAP therapy

Linkage l Obesity, sleep, stress, diet, and exercise l One study: if not enough sleep wake up with greater hunger l Proper amounts of sleep and exercise decrease appetite and obesity l Much easier to obtain proper sleep and treat sleep apnea than to diet

Sleep Apnea & Other Conditions l Diabetes greatly worsened by Sleep Apnea l Better control of Sleep Apnea leads to better control of Diabetes l Sleep deprivation in normal young people leads to a diabetic state l Hypertension caused and worsened by Sleep Apnea l Fibromyalgia has a strong component of sleep disorder, new treatment: Xyrem

Obesity l Obesity, Sleep Apnea promote each other l Hormonal links: leptin decreases and ghrelin increases hunger, while having opposite effects on sleep l Unfortunately medical trials with leptin have not been fruitful l Body is programmed: if not sleeping then eat more, in particular CHO and fat

Obesity and Sleep Deprivation l Direct link with avoiding sleep and obesity l Risk of obesity rises with sleep deprivation l Less than 4 hours : 73% risk l Five hours : 50% risk l Six hours : 23% risk l Less sleep: lower leptin levels l Obese persons sleep less

Obesity & Sleep Apnea l Sleep apnea, obesity promote each other l BMI: Body Mass Index l Underweight: <19 l Normal : 19 – 24 l Overweight : 25 – 29 l Obese : 30 – 39 l Morbidly Obese: 40 or above l If obese RISK of Sleep Apnea is the BMI

Approach to Weight Loss l Directly Dieting in long run: 5 to 10% l By regular Exercise: 20 to 30% l Avoid Sleep Deprivation when associated with obesity: 50 to 70% l Treatment of Sleep Apnea associated with obesity: 50 to 70% l Treating sleep disorders is a promising approach to obesity control
