Blood sugar levels staying around 250 for several months suggest that your diabetes is not well controlled at the moment. Glucobay-M 50, Glimepiride, and Sangly-M may help lower sugar levels, but sometimes diabetes progresses over time, and the body stops responding adequately to the same treatment. Diet habits, stress, poor sleep, infections, weight changes, and irregular physical activity can also keep sugar levels high despite regular medicines. A detailed review with your doctor is important because persistent high readings for many months may increase the risk of complications affecting the eyes, kidneys, nerves, and heart. Your doctor may need to check HbA1c, kidney function, meal pattern, medicine timing, and lifestyle before deciding whether the current treatment should be adjusted or changed. Reducing sugary foods, bakery items, sweet drinks, and overeating at night may help improve control. Regular walking, proper sleep, hydration, and eating balanced meals at fixed times can also naturally support better sugar stability. Consult your doctor soon if you develop excessive thirst, blurred vision, weight loss, frequent urination, numbness, or unusual tiredness along with persistently high sugar levels.
