Purpose The doctor–patient relationship is often challenged by complex communication issues and nondisclosure of important related medical information, especially in diabetes management. Very little information is known about diabetic patient nondisclosure to their doctors. The present study evaluated the prevalence of nondisclosure of information by persons with type 1 and type 2 diabetes mellitus to healthcare providers and its associated factors among the Saudi population, as well as the differences between persons with type 1 and type 2 diabetes mellitus. Methods A cross-sectional study targeting persons with type 1 and type 2 diabetes mellitus was conducted at King Saud University Medical City, Saudi Arabia, Riyadh. An online self-administered questionnaire was used to collect data. Results A total of 285 participants were included in the study (155 [54.4%] and 130 [45.6%] type 1 and 2 diabetic patients, respectively). Having an unhealthy diet (25.3%, n = 72), not regularly exercising (23.5%, n = 67), hiding some glucose readings (23.2%, n = 65), and not following instructions for weight loss (22.8%, n = 44) were the most common types of nondisclosed information among diabetic patients. The nondisclosure of information was significantly higher among type 2 patients (29.2%) than type 1 diabetic patients (18.7%) in terms of not participating in regular exercise (p = 0.018). Similarly, the nondisclosure of information was significantly higher among persons with type 1 diabetes compared to persons with type 2 diabetes in terms of hiding some glucose readings (p < 0.001) and not disclosing hyperglycemia (p = 0.011). Conclusion Nondisclosure of important related medical information among diabetic patients to their healthcare providers is prevalent among the Saudi population. Furthermore, the types and causes of nondisclosed information differ among persons with type 1 and type 2 diabetes mellitus.
