OHS Morbidity and Mortality

Morbidity


Not all severely overweight people develop pickwickian syndrome but most of it have, especially on middle aged people.  Obesity is associated with lots of medical health problems and is a component of the metabolic syndrome (is a combination of medical disorders that, when occurring together, increase the risk of developing cardiovascular disease and diabetes). Severely overweight people with pickwickian syndrome when diagnosed are much more likely to have hypoventilation (breathing at an abnormally slow rate, resulting in an increased amount of carbon dioxide in the blood), hypertension (high blood pressure: a common disorder in which blood pressure remains abnormally high, a reading of 140/90 mm Hg or greater), diabetes (metabolic diseases in which a person has high blood sugar), hypothyroidism (condition in which the thyroid gland does not make enough thyroid hormone), congestive heart failure (inability of the heart to supply sufficient blood flow to meet the needs of the body) and cor pulmonale (enlargement of the right ventricle of the heart). Patients with pickwickian syndrome are more often to be admitted in hospital compared to patients with similar severely overweight but without hypoventilation. 


Mortality

Patients with Obesity hypoventilation syndrome that undergo medical attention have less mortality rate. Patients with a severe complication show that 23% of mortality rate around 18 months and 46% within 50 months. Patients with severe complication and receive a positive airway pressure treatment reduces the mortality rate up to 10%.
