Diabetic Ketoacidosis Symptoms
People with diabetes don't have the luxury of that auto-sensing. Not enough insulin and the glucose levels in the blood stream start to rise; too much insulin, and they plummet.
The consequences of hypoglycemia are easy to understand. No energy source, no function - and the first organ to go is the brain. It needs glucose to function and without it, the brain shuts down quickly. Confusion, lethargy, and coma occur quickly. Blood sugar is one of the first things checked on scene of a comatose patient, because it's so easy to fix and very embarrassing for an EMT to miss.
