Ever suffered from dehydration? This happens more than a lot of people realize, and it can be really serious.
For people with Diabetes, the risk of dehydration is even greater, because higher than normal blood glucose depletes fluids. To get rid of the glucose, the kidneys will try to pass it out in the urine, but that takes water. So the higher your blood glucose, the more fluids you should drink, which is why thirst is one of the main symptoms of Diabetes.
Mild dehydration symptoms include headache, dry mouth and eyes, dizziness, fatigue, and dark-colored urine. Severe dehydration causes all those symptoms plus low blood pressure, sunken eyes, weak pulse and/or rapid heartbeat, confusion, and lethargy. But some people don’t get these symptoms, especially older people. It seems that thirst signals become weaker as we age. Diabetes may get people used to thirst so they don’t feel it as much.
If we aren’t drinking enough water, the kidneys still need water to eliminate excess glucose and other unwanted products. So they will basically raid the rest of the body for fluid to keep functioning. Gradually, our cells become dryer and dryer, which we might first notice in the eyes and mouth. Keeping yourself hydrated keeps everything functioning smoothly, minimizing your risk.
