Weighing the Impact of CPAP Therapy on Body Mass in Persons With OSA

Abstract

Several studies have demonstrated that when used adequately, CPAP therapy mitigates several negative consequences of OSA, including excessive sleepiness and hypertension, and improves quality of life.1,2 However, concerning is the observation by several researchers that use of CPAP has been associated with weight gain.3,4 This is a bothersome finding because increased weight is generally associated with the development or worsening of OSA and adverse health outcomes. Furthermore, a fear of weight gain might negatively influence the decision of patients with OSA to accept or be adherent to CPAP therapy.
