What is an essential action to take on a sick day for someone with diabetes?

Injecting insulin and checking glucose every 3-4 hours is crucial for someone with diabetes on a sick day because illness can significantly impact blood glucose levels. When a person is sick, their body may produce stress hormones that can increase blood sugar levels, making it essential to monitor these levels closely.

Regular monitoring allows for timely adjustments to insulin doses if blood glucose levels rise, preventing dangerous complications such as hyperglycemia or diabetic ketoacidosis. Moreover, maintaining insulin injections ensures that glucose is managed effectively, even if the person is unable to eat their normal diet or if food intake is erratic due to illness. This proactive approach is vital for managing diabetes effectively, particularly during times of stress or sickness.
