Diagnosis

Your doctor sets your target blood sugar range. For many people who have diabetes, Mayo Clinic generally recommends the following target blood sugar levels before meals:


Between 80 and 120 mg/dL (4.4 and 6.7 mmol/L) for people age 59 and younger who have no other underlying medical conditions

Between 100 and 140 mg/dL (5.6 and 7.8 mmol/L) for people age 60 and older, those who have other medical conditions, such as heart, lung or kidney disease, or those who have a history of low blood sugar (hypoglycemia) or who have difficulty recognizing the symptoms of hypoglycemia

For many people who have diabetes, the American Diabetes Association generally recommends the following target blood sugar levels:


Between 80 and 130 mg/dL (4.4 and 7.2 mmol/L) before meals

Less than 180 mg/dL (10 mmol/L) two hours after meals

Your target blood sugar range may differ, especially if you're pregnant or you have developed diabetes complications. Your target blood sugar range may change as you get older, too. Sometimes, reaching your target blood sugar range is a challenge.


Treatment

Talk to your doctor about managing your blood sugar and understand how different treatments can help keep your glucose levels within your goal range. Your doctor may suggest the following treatments:


Get physical. Regular exercise is often an effective way to control your blood sugar. However, don't exercise if ketones are present in your urine. This can drive your blood sugar even higher.

Take your medication as directed. If you have frequent episodes of hyperglycemia, your doctor may adjust the dosage or timing of your medication.

Follow your diabetes eating plan. It helps to eat smaller portions and avoid sugary beverages and frequent snacking. If you're having trouble sticking to your meal plan, ask your doctor or dietitian for help.

Check your blood sugar. Monitor your blood glucose as directed by your doctor. Check more often if you're ill or you're concerned about severe hyperglycemia or hypoglycemia.

Adjust your insulin doses to control hyperglycemia. Adjustments to your insulin program or a supplement of short-acting insulin can help control hyperglycemia. A supplement is an extra dose of insulin used to help temporarily correct a high blood sugar level. Ask your doctor how often you need an insulin supplement if you have high blood sugar.
