My father is having
diabetes for 23 years. From last month he started taking insuline. He is following a proper diet and taking his meal on proper time without any delay. Thorough out the day his blood
sugar level remains normal even at morning. But during night after dinner his sometimes his blood sugar level becomes 11-13 mmol/L sometime it remains under 10mmol/L.
However he has split his meal into two. What should be done to overcome from this problem.
