Impact of Illicit Drug Use on Nutrient and

Impact of Illicit Drug Use on Nutrient and Hormone Levels in Male Roux-en-Y Surgery Patients M. A. C. Manoukian; J. A. Harris; A. D. Carr M. D. ; M. J. Campbell M. D. University of California Davis School of Medicine Introduction Patients being evaluated for bariatric surgery often suffer from metabolic and vitamin deficiencies 1. Roux-en-y gastric bypass changes the intestinal anatomy of patients possibly leading to further metabolic and vitamin abnormalities 2. Illicit drug use has previously been reported to alter metabolism and nutrition levels in nonsurgical patients 3. Previous studies have illustrated that obese people are more likely to use cannabis, cocaine, and amphetamine than non-obese people 4 -7. The effect of prior use of illicit drugs on Methods preoperative and post-operative vitamin levels • Ahas chart review male patients undergoing Roux-en-Y not beenofwell evaluated. surgery at UC Davis Medical Center between 2008 and 2011 was conducted. Patients with no history of illicit drug use from 2008 and patients with a history of illicit drug use from 2008 -2011 were identified. • Continuous data were analyzed utilizing a homoscedastic two tailed T -test. • Categorical data were analyzed utilizing a Pearson’s Chi Squared Test. Results • We identified 52 male patients who met our inclusion criteria. • 28 (51. 85%) patients had no history of illicit drug use. • 24 (46. 15%) patients had a history of illicit drug use. • All patients had stopped drug use prior to surgery.
