Gastric bypass surgery lowers fasting plasma ceramide concentrations. Plasma ceramide concentrations were measured before surgery (grey bars), 3 months (black bars) and 6 months (white bars) post-surgery. Panel (A) illustrates plasma concentration of ceramide subspecies in severely obese patients (N=13) before, 3 months (N=13) and 6 months (N=12) post-RYGB. Panel (B) illustrates total plasma ceramide concentrations at these time points. Data are expressed as means ± S.E.M. * P< 0.05 pre-surgery vs. 3 months and 6 months post surgery.
