TL;DRAbstract

OBJECTIVE: To determine whether or not Orlistat ingested prior to a meal causes an increased appetite response. STUDY DESIGN: A Review of three randomized controlled trials studies from 2003-2008 that were in the English language.

OUTOMES MEASURED: Outcomes measured in the studies were: sensation of appetite, hunger, fullness, nausea, bloating, heartburn, belching, epigastric burning, and prospective food consumption. Each study measured individual patient responses using a VAS (visual analogue scale). Demarchi et al (2004) used a gastric barostat to measure gastric distention and accommodation to a meal. Both Demarchi (2004) and Goedecke et al (2003) measured plasma CCK levels and Ellrichmann et al (2008) measured gherlin, GLP-1, and PYY in addition to CCK. In addition, Ellrichmann et al (2008) used an ultrasound to determine changes in gallbl
