Our evidence based clinical practice with diabetic patients especially in Ramadan fasting mainly formed from clinical research . Through literature review, it has been found out that there are various articles published for the awareness of patients and general population regarding safe fasting during Ramadan. But very few studies highlight the Ramadan specific knowledge of general practitioners engaged in providing care to people with diabetes, In this study ,we aimed to to assess level of literacy and practice of interns and residents in family and medicine departments in King Abdul-Aziz university regarding diabetes mellites management during Ramadan fasting, to provide baseline data to inform best implementation practices of guidelines to optimize the management of diabetes during Ramadan. Doctors were invited to participate in a cross-sectional  double blinded online-based survey. Target population were interns and residents in family and medicine departments in King Abdul-Aziz university within 6 months starting during 2023, The survey included items related to doctors  level of education about fasting in Ramadan for diabetic patients and their information providers, the type of patient who should not fast , symptoms of hypo and hyper-glycemia , healthy habits in fasting and timing and frequency of blood glucose measuring, . The analysis included descriptive statistics and group comparison. Out of the 83 responses, knowledge and educational level were slightly higher in family doctors, While both groups exhibit similar levels of general knowledge, key differences emerge in areas such as dietary counseling, medication adjustments, and identifying high-risk patients. These findings highlight the need for targeted educational interventions to optimize patient care.It is suggested that the doctors should receive  training regarding latest published guidelines to minimize variety in management plans between them .
