When You Are Sick

Anytime you are sick, even with a cold or the flu, you can get high blood sugar. If you have diabetes, it is very important to plan ahead. When you are sick your blood sugar can go very high. The high blood sugar could lead to very serious problems. Having a plan before you are sick will help you prevent more serious problems.

What Happens When You Are Sick

Your stress level goes up when you are sick. This causes your body to release a hormone to help fight the disease. In addition to fighting the disease, the hormones also make your blood sugar higher and keep the insulin from working.

High blood sugar can cause ketoacidosis in people with Type 1 diabetes and hyperosmolar hyperglycemic non-ketotic coma in people with Type 2 diabetes. Both of these conditions are very serious and can be life-threatening.

Make a "Sick Day Plan." Use the Plan to Help You. 

  • Talk with your provider about when you should call
  • Talk with your provider about if you should take your medicine
  • Ask the provider how often you should check your blood sugar and urine ketones
  • Ask your provider what medicine to take
  • Ask your provider when you should eat
  • Know how to talk with a provider on weekends, holidays and at night
  • Use your sick day worksheet to list your information and keep it in a safe place

ALWAYS ASK A PHARMACIST FOR HELP PICKING AN OVER-THE-COUNTER MEDICINE.

 ALL DIABETICS SHOULD HAVE THE FOLLOWING THS ON HAND: 

  • Sugar-free cough medicine 
  • Aspirin and non-aspirin pain medicine (ask your provider which ones you can take) •
  • Antacids 
  • Medicine for diarrhea and vomiting 
  • Thermometer 
  • Your glucometer and strip

WHEN SHOULD YOU MEASURE YOUR TEMPERATURE, BLOOD SUGAR, AND KETONES IF YOU ARE SICK?

People with Type 1 diabetes should monitor their blood sugar and ketones every four hours. People with Type 2 diabetes should check their blood sugar every two to four hours and check for ketones if the blood sugar is over 240mg/dl. Check your temperature every four hours and continue to monitor until you feel better.

Use your sick day record to record your blood sugars, urine ketones, temperature, and your symptoms. Also include what you have had to eat and what medicine you have taken. 

DIABETES MEDICINE

When you are sick you still need to take your medicine. Even if you are throwing up, do not stop your medicine unless your provider tells you not to take it. If you cannot take your pills, you may need insulin. The body makes extra glucose (sugar) when you are sick. Make sure you understand your provider’s instructions for what to take and how much.

Dehydration

Dehydration can be a problem if you do not replace your fluids or if you have diarrhea and vomiting.

Signs and Symptoms of Dehydration

  • Dry mouth
  • Thirst
  • Decreased urination 
  • Dry, flushed skin
  • Dry lips
  • Higher than normal body temperature

If you notice these signs of dehydration, drink clear liquids until signs go away.

If you can’t sip fluids call your provider immediately!

Medicine

When you are sick, you may want to take over-the-counter medicines. Always check the label for sugar before you buy them. Tell the pharmacist your medical problems (diabetes, hypertension, etc.) and ask for help to find sugar-free medicine. Many medicines can affect your blood sugar level. 

  •  Some antibiotics can lower blood sugar levels in people with Type 2 diabetes. 
  •  Decongestants and products to treat colds can increase your blood sugar level and blood pressure.

WHAT SHOULD YOU EAT WHEN YOU ARE SICK?

It is best if you can eat and drink your regular diet. Add plenty of fluids by drinking one half to one cup of sugar free liquids every one to two hours.

Some examples are: water, tea without sugar, instant broth, diet sodas, sugar- free Popsicles®, sugar-free Jell-O®, and soups. 

If you cannot eat and drink your regular food then eat or sip about 15 grams of carbohydrates every hour.

Examples are:

  • ½ cup low-fat ice cream
  • ½ cup soft pudding
  • ½ cup soft yogurt
  • ½ cup cooked cereal
  • ¼ cup sherbet
  • 1 tbsp honey
  • ½ cup Jell-O®
  • ½ cup regular soda
  • 1 cup creamed soup (thinned)
  • ½ cup grape juice
  • 1 cup milk
  • ½ twin Popsicle®
  • If you want more than one of the above in an hour, use sugar-free foods
  • It is easier for your body to digest carbohydrates than proteins and fat
  • Small frequent feedings are quickly absorbed and quickly changed to blood glucose
  • Keep a record of how much you eat and drink 
  • Have someone check in on you 

If you have been very sick to your stomach, start drinking clear liquids like broth, tea, apple juice or grape juice, eating Jell-O®, or Popsicles®. When you tolerate this, move on to full liquids like tomato or orange juice, ice cream, and cream soups.
