DKA can occur when you don’t have enough insulin to meet your body’s needs. As your blood glucose goes up, you lose glucose in your urine. When glucose is lost in urine it pulls fluid out with it. If you don’t replace the fluids you lose, you can become dehydrated.
Meanwhile, your body begins burning fat and protein from muscle tissue just to maintain health and energy. Normally your body uses carbohydrate (glucose) for maintenance, but because there isn’t enough insulin in your body, your cells can’t access the glucose in your blood. Your body then resorts to burning fat in an unhealthy way. Your liver becomes involved in fat-burning, and the by-product is ketones. The ketones build up and your blood becomes acidic.
As your blood becomes acidic from the ketones, your system starts shifting electrolytes around to counter the acid. You retain sodium and lose potassium, and that’s when it gets dangerous. Your blood becomes a toxic environment for your organs.
For example, an imbalance of potassium may affect your heart rhythm. Your brain may be affected, too, because it needs electrolytes as well as glucose to function. If your brain isn’t getting either the glucose or electrolytes it needs, you run the risk of a coma.
Hurst notes that your risk of DKA is not proportional to your blood glucose levels. “For some people, it can happen at 180 mg/dl, for others it’s a little higher. Your blood glucose doesn’t have to be up around 400 mg/dl,” she says. When in doubt, check your ketones.
The last thing you should do when you have DKA is work out. That will only cause more fat-burning, and not in the good way normally associated with exercise.
