<![CDATA[Type 2 Diabetes Mellitus (DM) is a chronic metabolic disease characterized by elevated blood glucose levels and requiring long-term self-management to prevent complications. In addition to pharmacological therapy, non-pharmacological strategies such as Time-Restricted Eating (TRE) may support daily blood glucose regulation. This case report aimed to describe short-term changes in blood glucose levels following the implementation of TRE in a patient with type 2 DM. This case report used an Evidence-Based Nursing (EBN) approach. The subject was a 58-year-old man diagnosed with type 2 DM for 10 years, with a body mass index of 26.17 kg/m² and a pre-intervention fasting blood glucose level of 145 mg/dL. The patient continued to be prescribed oral antidiabetic medication during the intervention. TRE was implemented for 3 days with a 10-hour eating window from 10:00 AM to 08:00 PM, without calorie restriction. Blood glucose monitoring included fasting blood glucose, 2-hour postprandial glucose after lunch and dinner, and bedtime glucose levels. Results were obtained by monitoring blood glucose levels and making observations during the TRE intervention, which were then analyzed descriptively by calculating blood glucose levels before and after the intervention. After 3 days of TRE, fasting blood glucose decreased to 83 mg/dL; 2-hour postprandial glucose after lunch was 121 mg/dL, after dinner was 123 mg/dL, and bedtime glucose was 95 mg/dL. No signs or symptoms of hypoglycemia were reported during the intervention. This case report showed a short-term downward trend in blood glucose levels during TRE implementation in a patient with type 2 DM. However, the findings should be interpreted with caution because they were obtained from a single patient over a short intervention period, and medication use, dietary intake, and physical activity were not strictly controlled.]]>
