  • During acute illnes, hospitalization, or surgery, insulin doses often need to be escated, sometimes with intravenous insulilion infusions to maintain target glucose levels.
  • Nutritional management should be integrated: high- calorie diets, consident carbohydrate intake (usually from 30- 60 g per meal depending on individuaal needs), and proper timing of trzustka enzymy support glycemic control.
