Type 2 diabetes
If you take insulin to manage type 2 diabetes, your doctor may recommend blood sugar testing several times a day, depending on the type and amount of insulin you use. Testing is usually recommended before meals and at bedtime if you're taking multiple daily injections. You may need to test only before breakfast and dinner if you use just an intermediate- or a long-acting insulin.
If you manage type 2 diabetes with noninsulin medications or with diet and exercise alone, you may not need to test your blood sugar daily.
