Ageing people requiring care are somewhat at the mercy of those responsible for their care. This situation necessitates a current knowledge of diabetes management and care from attendant health care p...rofessionals. In addition, those preparing meals need some guidance to ensure the provision of healthy and nutritious meals. Carers need to be alert to potential complications of diabetes (e.g. sick days, foot injuries, side effects of insulin administration) and must know how to respond to these situations so as to minimise problems. This chapter reviews the clinical signs and symptoms of diabetes and discusses the impact of this disease upon the person and the carer.
