Discuss with Your Healthcare Provider
Meals
Dierent types of meals and foods can impact your glucose levels and trend arrows in dierent ways, as can conditions
such as delayed gastric emptying. Some foods will raise your glucose more rapidly than others. Before using CGM
data to make treatment decisions, discuss with your healthcare provider about how to manage insulin dosing for
dierent types of food, and how to accurately calculate carbohydrates.
Insulin
Insulin does not instantly impact your glucose. For example, depending on the brand of rapid-acting insulin used,
onset of action can be from 5 to 15 minutes, peak eect in 1-2 hours and duration of action of 4-6 hours. Be sure to
understand when you can expect the insulin you take to start lowering your glucose, when its maximum eectiveness
is, and how long it lasts in your body continuing to lower your glucose. Working with your healthcare provider to
understand the onset, peak, and duration of your insulin action will help you avoid stacking insulin. Stacking insulin
is when you take a dose of insulin while a previous dose is still working at lowering your glucose. Hypoglycaemia,
sometimes severe, can result. Rather than reacting and taking insulin based on a high CGM value, be sure to consider
whether insulin from your most recent dose is still actively lowering your glucose.
Exercise
Even relatively mild exercise, if it is not part of your normal routine, may cause your glucose to change more rapidly
than usual. If your symptoms do not match your CGM value, or if your CGM value and trend arrow are not what you
expect, use your BG meter to make treatment decisions. Some people experience delayed-onset hypoglycaemia
hours after exercise. You should follow your healthcare provider’s recommendation on dosing insulin following
exercise to avoid low glucose.
