This study aimed to identify difficulties diabetic patients face during treatment in controlling the disease. A total of 24 diabetic patients, attended in the Nurse Educational Center for Adults and Elders in 2003, participated in the study. The data was collected individually, through a written report guided by a question previously elaborated, on a pre-scheduled date. The Content Analysis technique was used in the data analysis. The results showed several difficulties related to the treatment follow up: rejection and denial of the patient's condition, suffering and revolt due to restrictions imposed by the diet, physical activity and medication. It is possible to infer that the focus of the education approach should not be restricted to the transmission of knowledge; it should also include emotional, social and cultural aspects that also influence in the treatment follow up.
