What Are the Signs and Symptoms of Obesity Hypoventilation Syndrome? Many of the signs and symptoms of obesity hypoventilation syndrome (OHS) are the same as those of obstructive sleep apnea. This is because many people who have OHS also have obstructive sleep apnea. One of the most common signs of obstructive sleep apnea is loud and chronic (ongoing) snoring. Pauses may occur in the snoring.
Hypercapnia and respiratory acidosis ensue when impairment in ventilation occurs and the removal of carbon dioxide by the respiratory system is less than the production of carbon dioxide in the tissues. Lung diseases that cause abnormalities in alveolar gas exchange do not typically result in alveolar hypoventilation. Often these diseases stimulate ventilation and hypocapnia due to reflex receptors and hypoxia.
