Patients with diabetes should check their blood sugar levels often as a part of managing the disease. They should ask their medical care providers how often to check it, according to the American Diabetes Association. Checking blood sugar levels and treating them can help to prevent long-term consequences.

Changes in exercise routines, diet and medication are useful in managing blood sugar levels, notes the American Diabetes Association. However, a patient with a blood sugar level above 240 should not exercise without first checking his urine for ketones. If there are ketones in the urine, exercise sometimes increases the blood sugar level. When ketones are present, patients should consult their doctors regarding safer ways to lower their blood sugar levels.

If the doctor prescribes medication, the diabetic patient should take it according to the doctor's directions. Diabetics who take insulin sometimes need to adjust their insulin programs or supplement them with short-acting medication for better control, explains Mayo Clinic. When there is a concern about high or low blood sugar levels, patients should check insulin levels more often.
