- If you get sick, your blood sugar can be hard to manage. You may not be able to eat or drink as much as usual, which can affect blood sugar levels. Your doctor may ask you to test your blood sugar more often when you’re sick. That’s because when your body releases hormones to fight the illness, those hormones can also raise your blood sugar levels and increase how much insulin you need. This is especially important for people with type 1 diabetes since they depend on insulin to live.
- When your body doesn’t have enough insulin, it starts breaking down fat as fuel, which produces ketones. When too many ketones are produced too fast, they can cause diabetic ketoacidosis, or DKA. DKA is very serious and can cause a coma or even death.
- If you think you may have DKA, use an over-the-counter kit to test your urine for ketones. If ketones are present, call your doctor right away. You’ll probably need to go to the hospital for treatment.
- When you are sick even if your blood sugar is within your target range, continue taking your insulin and diabetes pills as usual.
