Diabetes mellitus causes macrovascular and microvascular damage, resulting in life-threatening complications. Exercise is an essential therapeutic intervention for diabetes mellitus. In individuals with this condition, exercise reduces cardiovascular risk and mortality, supports weight management, and enhances glycemic control. Greater tissue sensitivity to insulin contributes to improved glycemic regulation. Exercise is recommended for individuals with diabetes mellitus to improve glycemic control, reduce cardiovascular risk, and enhance overall fitness. However, patients with concomitant proliferative retinopathy, severe diabetic neuropathy, or symptomatic coronary artery disease should exercise with caution or under supervision. Proper implementation includes maintaining adequate hydration, monitoring blood glucose levels before and after exercise, and adjusting carbohydrate intake as needed to prevent hypoglycemia. Using appropriate footwear and selecting exercises that match an individual’s fitness level and medical condition help ensure safety and effectiveness. This activity for healthcare professionals is designed to enhance learners' competence in identifying patients with diabetes mellitus who have exercise indications and properly implementing exercise regimens in this population. Participants will deepen their understanding of the intervention's physiological effects, indications, contraindications, and best practices for preparation and execution. Patient education will also be emphasized. Greater proficiency will equip clinicians to collaborate more effectively within an interprofessional team caring for individuals with diabetes mellitus. Objectives: Screen patients with diabetes mellitus for exercise contraindications. Develop individualized exercise regimens for patients diagnosed with diabetes mellitus. Implement appropriate monitoring strategies based on clinical and diagnostic evaluations to assess the effectiveness of exercise regimens for individuals with diabetes mellitus. Collaborate with the interprofessional team to educate, treat, and monitor patients with diabetes mellitus to improve patient outcomes. Access free multiple choice questions on this topic.

Diabetes mellitus remains a critical global health burden. In 2021, the International Diabetes Federation estimated that around 537 million adults, representing 10.5% of the global population aged 20 to 79, were living with diabetes. Projections indicate this number will increase to 643 million by 2030 and reach around 783 million by 2045.[1] (IDF) Estimates from the World Health Organization indicate that diabetes mellitus will be the 7th most common cause of mortality worldwide. (WHO) Diabetes mellitus affects blood glucose metabolism and includes 2 main types: type 1, caused by relative or absolute insulin deficiency, and type 2, resulting from insulin resistance. Type 2 diabetes mellitus represents approximately 95% of all reported cases, while only 5% of individuals with diabetes have type 1.[2] Uncontrolled diabetes mellitus over time leads to macrovascular and microvascular injuries, resulting in life-threatening complications. Embracing a healthier lifestyle, including proper diet and regular exercise, is essential in improving glycemic control alongside medication, delaying the onset of diabetes and its complications.[3] The benefits of regular exercise in preventing these complications are well established. All types of exercise regimens contribute to improved glucose regulation. Despite being an essential therapeutic approach, most individuals with diabetes mellitus remain inactive, often due to a lack of patient awareness or insufficient counseling from the treatment team.[4][5] This activity aims to provide a summarized review and key clinical insights on the role of exercise in preventing and managing diabetes mellitus. This activity also emphasizes this lifestyle intervention's metabolic effects, indications, types, physiology, and clinical significance. Given the significantly higher prevalence of type 2 diabetes mellitus, the course will focus on the effects of exercise on individuals with this condition.

Maintaining an exercise program in patients with type 2 diabetes is essential, as it has been linked to improved glycemic control and a reduction in both microvascular and macrovascular complications, ultimately lowering morbidity and mortality. While the benefits of exercise for these patients are well established, implementing and sustaining an exercise regimen can be challenging.[33] An interprofessional team approach is often necessary to achieve successful outcomes. Endocrinologists, primary care physicians, diabetes educators, nursing professionals, obesity specialists, and physical therapists all play a critical role in educating patients on the importance of exercise as a therapeutic strategy for managing diabetes and reducing cardiovascular risk factors.[34] Close monitoring of blood glucose levels and HbA1c by primary care physicians or endocrinologists is recommended. Fluctuations in blood glucose, whether high or low, may prevent patients from engaging in physical activity, even though exercise is essential in managing diabetes mellitus. Some studies suggest that simple behavioral counseling by clinicians and nurse educators during clinic visits can improve adherence to exercise. Educating various healthcare professionals on delivering practical counseling techniques can further support patient engagement.[35] A physical therapy consultation can be particularly beneficial for patients who have been sedentary or suffer from joint conditions. Many individuals with type 2 diabetes prefer walking as their primary form of physical activity, making a pedometer-based intervention a motivating and effective strategy for increasing daily movement.[36][37] Since overweight and obesity are common in patients with type 2 diabetes, involving an obesity specialist to develop a tailored exercise regimen and, if appropriate, prescribe weight-loss medications may enhance patient outcomes. Sustaining an exercise regimen for more than 3 months can be challenging.[38] A 10-year study of 255 patients with diabetes mellitus enrolled in a diabetes education program emphasizing exercise showed a decline in compliance rates from 80% at 6 weeks to less than 50% at 3 months. By 1 year, the compliance rate had dropped to less than 20%.

Sustaining an exercise regimen for more than 3 months can be challenging.[38] A 10-year study of 255 patients with diabetes mellitus enrolled in a diabetes education program emphasizing exercise showed a decline in compliance rates from 80% at 6 weeks to less than 50% at 3 months. By 1 year, the compliance rate had dropped to less than 20%. In contrast, certain factors have been associated with higher levels of physical activity, including confidence in one's ability to exercise, social support, and access to facilities and safe walking areas.[39] An individualized approach incorporating behavior change strategies may improve long-term adherence. A coordinated interprofessional effort, with educators and counselors working alongside clinicians, can help optimize patient engagement and sustain exercise participation.
