Research is our hope for the future. But it can sometimes feel like something that doesn't affect our day-to-day lives or have any direct impact on us. So what does it feel like to actually take part in a research trial?
Allan and Lisa have both taken part in Diabetes UK-funded research trials, and tell us their stories.
Lisa has Type 1 diabetes and took part in an artificial pancreas study.
Allan has Type 2 and took part in research looking at the impact of a low-calorie diet on Type 2 diabetes.
