Dr Iqbal Ahmed graduated from the University of Manchester, England in 1977 and trained at St Bartholomew’s hospital, London before coming to the University of Alberta, Edmonton to complete a fellowship in Respiratory Medicine. As respirologist at the Royal Alexandra and Charles Camsell hospitals in Edmonton, he established the Asthma Teaching Program and Asthma Clinic in 1989 and the Sleep Apnea Program at the Royal Alexandra hospital in 1991. Since 1996, he has been respirologist with VCH, based at the Richmond Hospital and was Director of its Intensive Care unit from 1996-99 He established the first Respiratory Rehabilitation program at the Richmond Hospital in 1999 and is currently Director of the Pulmonary Function Laboratory and Associate Clinical Professor of Medicine at UBC. His research interests have included radiation lung injury (MSc, U of Alberta 1984), the natural history of asthma (MPH, Johns Hopkins University, 1995) and Obstructive sleep apnea.
Obstructive sleep apnea (OSA) is a major medical problem due largely to a combination of maxillo-facial / nasopharyngeal abnormalities and obesity, in differing proportion. The epidemic of obesity in western societies is considered to be the main culprit behind the increasing prevalence of OSA. Treatment options are limited mainly to nasal CPAP / BiPAP and the use of a dental device. Weight loss is beneficial but difficult to sustain with dieting alone. We are interested in the effects of weight loss on OSA in a multi-disciplinary provincial bariatric surgical program based at The Richmond Hospital. Our research tracks a variety of respiratory and non-respiratory parameters to explore the effects of weight loss in this phenotype of sleep apnea. The objective is to better understand the various components which contribute to OSA.
