Why Blood Sugar Levels Rise in Winter: Expert Tips for Diabetic Patients

As winter approaches, many people notice fluctuations in their blood sugar levels. According to medical experts, colder temperatures can slow down the body’s metabolism, leading to reduced physical activity and increased cravings for comfort foods—both of which can contribute to high blood glucose levels. In addition, insulin sensitivity and the body’s response to it may change during winter, making it more challenging to maintain stable sugar levels.

Dr. Kamaljeet Singh Kainth, a senior physician from Delhi, explains that diabetics need to be extra cautious during the cold season. He advises maintaining a low-carb diet rich in fresh fruits and green vegetables while avoiding fried and sugary foods. Regular physical activity—at least 30 minutes a day—is crucial. He also stresses the importance of staying hydrated, even in winter, and checking blood sugar levels frequently. If your readings remain high, seek medical advice promptly rather than ignoring the issue.

Warning Signs to Watch For
Dr. Kainth highlights that symptoms like frequent urination, excessive thirst, or sudden changes in weight may indicate high blood sugar levels. If such symptoms appear, get a random blood sugar test followed by an HbA1c test to assess your average sugar levels over the past few months. Based on these results, your doctor can adjust your treatment plan. Meanwhile, continue following a healthy routine—avoid sweets, exercise daily, and if the cold keeps you indoors, try simple home workouts.

Important Winter Care Tips for Diabetics:

  • Take prescribed medications regularly, especially if you also have high blood pressure.

  • Get at least 8 hours of sleep every night.

  • Avoid stress—practice meditation or yoga to stay calm and balanced.

  • Stay active and keep your body warm to maintain good circulation.

By paying attention to these small but essential habits, diabetic patients can effectively manage their blood sugar levels throughout the winter season.
