Read our Type 1 Diabetes Mellitus research guide →This study looks at a strategy that some young people with type 1 diabetes already use on their MiniMed 780G insulin pump: entering a fake amount of carbohydrates to trick the pump into giving an extra dose of insulin when blood sugar is running high. Researchers want to understand whether this trick actually helps keep blood sugar in a better range or if it causes problems. The study will compare two groups of young people — one group will keep using this trick for two weeks and then stop, while the other group will stop first and then try it again.
Many young people have figured out this workaround on their own to help control stubborn high blood sugar, but no one has studied whether it's actually safe and helpful. Understanding whether this trick works better than the pump's regular settings could help doctors give better advice to patients about managing their diabetes.

You would be randomly put into one of two groups. One group will continue using the fake carb trick for 2 weeks, then stop using it for 2 weeks. The other group will do the opposite — stop first, then use it again. Before and between each phase, there are 2-week periods where the pump system gets adjusted to work best. Throughout, you'll keep a log of when you use the trick, and your blood sugar data from the pump will be watched carefully. The whole study lasts about 8 weeks.
