Sherri Buffington knows right away when she's stressed out.
"I'll start to feel hot," she says. Once the warmth floods her body, she tests her blood sugar. It's almost always high.
Buffington isn't imagining the connection. Stress is known to spike blood sugar, also called glucose. "It's a very common occurrence," says Kevin Pantalone, DO, staff endocrinologist at Cleveland Clinic. "Stress can increase levels of hormones in the body, particularly cortisol, which can make blood sugar rise."
Test for ketones if you have type 1 diabetes and your sugar level is above 240mg/dL -- or if your doctor tells you to. Ketones are a form of waste that people with type 1 make when they’re under stress (like an illness). Call the doctor if you find ketones in your urine. Depending on how sick you are, he may suggest you go to the emergency room.
Check your temperature regularly.
Drink liquids if you can’t keep solid food down. Have one cup of liquid every hour while you’re awake to prevent dehydration. If you can’t hold down liquids, you may need to go to the emergency room or hospital.
Don’t stop taking insulin, even if you can’t eat solid food. You may need to eat or drink something with sugar so that your blood sugar doesn't drop too low.
