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 less and avoid sugary beverages. 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 frequently if you're ill or you're concerned about severe hyperglycemia or low blood sugar (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.
Emergency treatment for severe hyperglycemia
If you have signs and symptoms of diabetic ketoacidosis and diabetic hyperosmolar syndrome, you may be treated in the emergency room or admitted to the hospital. Emergency treatment can lower your blood sugar to a normal range. Treatment usually includes:
- Fluid replacement. You'll receive fluids — either orally or through a vein (intravenously) — until you're rehydrated. The fluids replace those you've lost through excessive urination, as well as help dilute the excess sugar in your blood.
- Electrolyte replacement. Electrolytes are minerals in your blood that carry an electric charge. The absence of insulin can lower the level of several electrolytes in your blood. You'll receive electrolytes through your veins to help keep your heart, muscles and nerve cells functioning normally.
- Insulin therapy. Insulin reverses the processes that cause ketones to build up in your blood. Along with fluids and electrolytes, you'll receive insulin therapy — usually through a vein.
As your body chemistry returns to normal, your doctor considers what may have triggered the severe hyperglycemia. Depending on the circumstances, you may need additional treatment.
If your doctor suspects a bacterial infection, he or she may prescribe antibiotics. If a heart attack seems possible, your doctor may recommend further evaluation of your heart.
