Type 2 diabetes

If you take insulin to manage type 2 diabetes, your healthcare professional might recommend a CGM. Or you may need blood sugar testing several times a day. The exact number of times depends on the type and amount of insulin you use. Often, testing is advised before meals and at bedtime if you take more than one shot of insulin a day. You may need to test only before breakfast and sometimes before dinner or at bedtime if you use an intermediate- or a long-acting insulin.

In general, you might need to test more often if you:

• Are sick.
• Have to drive a long distance.
• Change the way you eat or exercise.

You might not need to test your blood sugar every day if you manage type 2 diabetes with medicines that are not insulin. You also might not need to test daily if you manage the condition with diet and exercise alone.
