        Lipase Supplementation before a High-Fat Meal Reduces Perceptions of Fullness in Healthy Subjects

        ( Max E Levine ),( Sara Yanchis Koch ),( Kenneth L Koch ) 대한소화기학회 2015 Gut and Liver Vol.9 No.4

        Background/Aims: Postprandial symptoms of fullness and abdominal discomfort are common after fatty meals. Gastric lipases hydrolyze 10% to 20% of dietary triglycerides during the stomach trituration period of digestion. The aim of this study was to evaluate the effects of acid-resistant lipase on upper gastrointestinal symptoms, including fullness and bloating, as well as on gastric myoelectrical activity after healthy subjects ingested a high-fat, liquid meal. Methods: This study utilized a double-blind, placebo-controlled, crossover design with 16 healthy volunteers who ingested either a capsule containing 280 mg of acid-resistant lipase or a placebo immediately before a fatty meal (355 calories, 55% fat). Participants rated their stomach fullness, bloating, and nausea before and at timed intervals for 60 minutes after the meal. Electrogastrograms were obtained to assess the gastric myoelectrical activity. Results: Stomach fullness, bloating, and nausea increased significantly 10 minutes after ingestion of the fatty meal (p<0.01), whereas normal gastric myoelectrical activity decreased and tachygastria increased (p<0.05). With lipase, reports of stomach fullness were significantly lower compared with placebo (p<0.05), but no effect on gastric myoelectrical activity or other upper gastrointestinal symptoms was observed. Conclusions: The high-fat meal induced transient fullness, bloating, nausea, and tachygastria in healthy individuals, consistent with postprandial distress syndrome. Acid-resistant lipase supplementation significantly decreased stomach fullness. (Gut Liver 2015;9:464-469)
