Obstructive sleep apnea (OSA), characterized by cessation of air flow for a minimum of 10 seconds despite continuous respiratory effort, is a prevalent condition in our society. Recent studies demonstrate that OSA is an independent risk factor for insulin resistance and the cardiometabolic syndrome. Hypoxemia and sleep fragmentation from OSA appear to produce autonomic activation, alterations in neuroendocrine function, and increased amounts of inflammatory cytokines (interleukin 6 and tumor necrosis factor alpha). These variables have important roles in the pathogenesis of insulin resistance and the cardiometabolic syndrome. It can be concluded that insulin sensitivity, a key contributor to the pathogenesis of the cardiometabolic syndrome, is mainly determined by the extent of obesity and, to a lesser extent, by OSA. The authors review OSA and summarize recent discoveries and proposed mechanisms of the causal relationship that OSA has with insulin resistance and the cardiometabolic syndrome independent of many confounding comorbidities.

D007333	Insulin Resistance	Diminished effectiveness of INSULIN in lowering blood sugar levels: requiring the use of 200 units or more of insulin per day to prevent HYPERGLYCEMIA or KETOSIS.	Insulin Sensitivity,Resistance, Insulin,Sensitivity, Insulin
D005947	Glucose	A primary source of energy for living organisms. It is naturally occurring and is found in fruits and other parts of plants in its free state. It is used therapeutically in fluid and nutrient replacement.

D001341	Autonomic Nervous System	The ENTERIC NERVOUS SYSTEM; PARASYMPATHETIC NERVOUS SYSTEM; and SYMPATHETIC NERVOUS SYSTEM taken together. Generally speaking, the autonomic nervous system regulates the internal environment during both peaceful activity and physical or emotional stress. Autonomic activity is controlled and integrated by the CENTRAL NERVOUS SYSTEM, especially the HYPOTHALAMUS and the SOLITARY NUCLEUS, which receive information relayed from VISCERAL AFFERENTS.

D014409	Tumor Necrosis Factor-alpha	Serum glycoprotein produced by activated MACROPHAGES and other mammalian MONONUCLEAR LEUKOCYTES. It has necrotizing activity against tumor cell lines and increases ability to reject tumor transplants. Also known as TNF-alpha, it is only 30% homologous to TNF-beta (LYMPHOTOXIN), but they share TNF RECEPTORS.

D015850	Interleukin-6	A cytokine that stimulates the growth and differentiation of B-LYMPHOCYTES and is also a growth factor for HYBRIDOMAS and plasmacytomas. It is produced by many different cells including T-LYMPHOCYTES; MONOCYTES; and FIBROBLASTS.

D045422	Continuous Positive Airway Pressure	A technique of respiratory therapy, in either spontaneously breathing or mechanically ventilated patients, in which airway pressure is maintained above atmospheric pressure throughout the respiratory cycle by pressurization of the ventilatory circuit.

D020181	Sleep Apnea, Obstructive	A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES.

D024821	Metabolic Syndrome	A cluster of symptoms that are risk factors for CARDIOVASCULAR DISEASES and TYPE 2 DIABETES MELLITUS. The major components of metabolic syndrome include ABDOMINAL OBESITY; atherogenic DYSLIPIDEMIA; HYPERTENSION; HYPERGLYCEMIA; INSULIN RESISTANCE; a proinflammatory state; and a prothrombotic (THROMBOSIS) state.
