Diabetes care should be designed for each individual patient. Some patients may need to test (monitor) more often than others do. How often you use your glucose meter should be based on the recommendation of your health care provider. Self-monitoring of blood glucose (SMBG) is recommended for all people with diabetes, but especially for those who take insulin. The role of SMBG has not been defined for people with stable type 2 diabetes treated only with diet.
As a general rule, the American Diabetes Association (ADA) recommends that most patients with type 1 diabetes test glucose three or more times per day. Pregnant women taking insulin for gestational diabetes should test two times per day. ADA does not specify how often people with type 2 diabetes should test their glucose, but testing often helps control.
Often, self-monitoring plans direct you to test your blood sugar before meals, 2 hours after meals, at bedtime, at 3 a.m., and anytime you experience signs or symptoms. You should test more often when you change medications, when you have unusual stress or illness, or in other unusual circumstances.
