“Diabetes type 1 is very different from your standard disease. Insulin requirements vary greatly from one day to another and there is no way patients can know what they need,” Roman Hovorka, Professor at the University of Cambridge, explained to me during an interview. His research group is working on the development of an algorithm that can accurately predict insulin requirements for a specific patient at any moment.

Normally, blood glucose levels are tightly controlled by insulin, a hormone produced by the pancreas. Insulin lowers the blood glucose level. When the blood glucose elevates (for example, after eating food), insulin is released from the pancreas. This release of insulin promotes the uptake of glucose into body cells. In patients with diabetes, the absence of insufficient production of or lack of response to insulin causes hyperglycemia. Diabetes is a chronic medical condition, meaning that although it can be controlled, it lasts a lifetime.
