Abstract: A computer-implemented method for sharing information and managing diabetes diagnosis and treatment. The method comprises providing a web portal account accessible by both a patient and health care provider. The account may be associated with a portable medical device. The method includes receiving, at one or more servers, medical and usage data from the portable medical device. The medical data may be associated with the patient and the usage data may be associated with usage of the medical device by the patient. Statistics related to the medical or usage data are accumulated at one or more servers over a period of time, and may be accessible in the web portal account. The method includes evaluating the statistics in relation to a treatment criteria, and sending a treatment recommendation to the patient or the health care provider when at least one of the statistics meets or exceeds a predetermined treatment criteria.
