If you can't process sugar from the foods you eat, you get no energy. You can fill the car with fuel, but if the engine doesn't start and burn it up, you aren't going anywhere. So diabetics have to take injections of insulin every day. Sometimes as many as five or six shots daily. You also test your blood sugar levels, pricking your finger to measure the amount of insulin in your system.
Many people think that's all there is to the disease.
Take your shots and you're fine. But diabetes is a juggling act. If you have too much insulin in your system, you get dizzy, sweaty, sometimes faint. If at that point you don't eat sugary foods, like candy, you can slip into a coma and die. If you have too little insulin, your blood sugar level skyrockets.
