This is a non-interventional, prospective study where no visits or additional interventions to the daily practice of the physician will be performed. Glucophage XR® has recently been available in Thailand for the treatment of patients with type 2 diabetes. A prospective observational study will be valuable to provide information on the day-to-day experience of using Glucophage XR® in the management of this patient population. The data may provide an insight into the use of Glucophage XR® in routine clinical practice in Thailand.
