Millions of people are suffering from Diabetes Mellitus today. This amount is expected to increase over the next few years due to mul- tiple factors, not only genetic ones, but also because of our sedentary lifestyle according to the World Health Organization. This work presents a cloud-based system which consists of a web plat- form, a mobile application and a set of services to facilitate a centralised study of the most relevant parameters involved in diabetes self-care. The system was evaluated by a group of diabetic patients in which 75% of them showed their satisfaction using this system for diabetes self-control. Also, the acceptance level between user and system was studied by means of an usability analysis focused on several evaluation techniques.

Insulin is a hormone that absorbs glucose from the bloodstream and converts it into energy for the body’s cells. There are several types of Dia- betes due to the different hormonal behavior, although two are the most known. In Diabetes Type I, pancreas does not produce insulin, or insulin does not work properly (Diabetes Type II). Likewise, diabetic patients suffer periods of hypo- glycemia (low levels of blood sugar) which should be treated carefully. Diabetes Type I usually appears during childhood requiring a permanent treatment with insulin, since it is not produced by the body itself. While Diabetes Type II causes a deficit in insuline production by the pancreas, being necessary a partial insuline treatment. However, there are other less common types of diabetes as it was mentioned before. c  Springer International Publishing AG 2017 S.F. Ochoa et al. (Eds.): UCAmI 2017, LNCS 10586, pp. 227–239, 2017.
