Diabetology is the clinical science of diabetes mellitus, its diagnosis, treatment and follow-up. It can be considered a specialised field of endocrinology. The term diabetologist is used in several ways. In other contexts the term diabetologist refers to any physician, including endocrinologists, whose practice and/or research efforts are concentrated mainly in diabetes care. Apart from regulating medication dosage and timing, a diabetologist will also concern themselves with the potential consequences of diabetes, e.g. retinopathy, nephropathy and peripheral neuropathy.
