People of black African and Caribbean descent have a greater risk of developing type 2 diabetes than white Europeans. The aim of this study is to increase our knowledge of how the condition may arise, and what underlies this increased risk. Following a successful screening visit to confirm eligibility for the study, we will be investigating how quickly a glucose drink empties out of the stomach in 30 white Europeans and 30 people of black African or Caribbean descent. In addition, we will study the impact that gastric emptying rate has on blood glucose and satiety hormones released normally by the gut in response to eating. Blood and breath samples will be collected before and during an oral glucose tolerance test.
