When we're stressed, our bodies need extra energy to help us cope and recover. This is true whether bodies are under stress from illness or injury or are dealing with the effects of emotional stress, both good and bad.
To meet the demand for more energy, the body responds by releasing into the bloodstream sugar that's been stored in the liver, causing blood sugar levels to rise.
In someone without diabetes, the pancreas responds to the rise in blood sugar by releasing enough insulin into the bloodstream to help convert the sugar into energy. This brings blood sugar levels back down to normal.
In someone with diabetes, the extra demand usually means needing to take more diabetes medicine (insulin or pills.) To make sure your body is getting enough medicine to help keep your blood sugar levels close to normal, you'll need to test more often when you are:
In people with type 1 diabetes, blood sugar levels rise in response to stress, but the body doesn't have enough insulin to turn the sugar into energy. Instead, the body burns stored fat to meet energy needs. When fat is burned for energy, it creates waste products called ketones. As fat is broken down, ketones start to build up in the bloodstream.
High levels of ketones in the blood can lead to a serious condition known as diabetic ketoacidosis (DKA), which can cause a person to lose consciousness and go into a diabetic coma.
In people with type 2 diabetes, the body usually has enough insulin available to turn sugar into energy, so it doesn't need to burn fat. However, stress hormones can cause blood sugar levels to rise to very high and even dangerous levels.
People with type 2 diabetes usually aren't at risk for high ketone levels or DKA, but they can develop a condition known as non-ketosis hyperosmolar hyperglycemia (NKHH).
Both DKA and NKHH cause a person to urinate more. Being sick can also lead to vomiting and diarrhea. It's very important to replace these lost fluids quickly. If a person gets seriously dehydrated, he or she might need to go to an emergency room.
Plan ahead so you can stay in control of your diabetes if you get sick or too stressed.
Sometimes people don't feel hungry when they're sick or stressed, but they still need food for energy. Our bodies need fuel to help us cope with stress and recover from illness or injury. Aim for about 150 grams of carbohydrate each day.
You can get carbohydrates from drinks and foods that are ready to use and easy to prepare. Some good carbohydrate sources you might want to have on hand include:
Be sure to drink plenty of water (1 to 2 cups each hour), especially if you have a fever, diarrhea, or are vomiting.
If you have type 1 diabetes and are sick or under stress, it's important to check your blood sugar level every 2 to 4 hours to make sure it stays as close to normal as possible. If your blood sugar is over 240, and you've been sick or feel like you're coming down with something, check your urine for ketones.
If your blood sugar is over 240 from two different tests taken 2 to 3 hours apart and your test shows moderate or heavy ketones both of those times, call your doctor.
Even if you don't have ketones in your urine, you should call a member of your health care team if your blood sugar stays above 240 for several readings over a few hours, especially if you're vomiting.
If you have type 2 diabetes, check your blood sugar every 2 to 4 hours to make sure it stays as close to your normal baseline as possible. Call your doctor, or the Consulting Nurse Service, if your blood sugar stays above 300 mg/dl for several hours especially if you didn't eat or drink anything high in carbohydrate or sugar that would lead to such a high blood sugar level.
You can get sick-day supplies from your Group Health pharmacy and make a kit to have on hand. These supplies are available at a very small cost to Group Health members. Be sure to check expiration dates and replace as needed.
Ask your pharmacist for any of the following supplies, if you don't already have them on hand:
People with type 1 diabetes also should ask their doctors or pharmacists about the following supplies and make sure they understand how and when to use them:
Keep taking your diabetes medicines that lower blood sugar, such as insulin or glyburide. You might need a higher dose because stress and illness can raise your blood sugar more than usual. Check with your health care team before you increase your dose.
If you take metformin (Glucophage) and have a fever or diarrhea or are vomiting, stop taking the metformin and call your health care team for advice about what you should do next.
If you want to take any over-the-counter cold or flu medicines, be sure to ask your pharmacist or doctor which ones are safe for you. Many cold and flu medicines have added sugars or can interact with other medicine you're taking.
