Dehydration is the medical term for what happens when the body loses more fluid than you take in. The human body loses water by sweating and producing urine, so you must replace the lost fluid by drinking water and other beverages. People with diabetes also have an increased risk of becoming dehydrated due to high blood sugar which can cause frequent urination.

Causes of Dehydration

  • Fever
  • Heat exposure
  • Too much exercise
  • Vomiting, diarrhea and increased urination
  • Certain diseases such as diabetes
  • Inability to drink
  • Sun burns or mouth sores

Fluid Replacement vs. IV

Intravenous fluids replace the fluid lost through sweating, vomiting, diarrhea and frequent urination. These fluids often contain potassium, glucose, and sodium, which are electrolytes your body needs to function normally. You may also need to replace lost fluids by drinking sports drinks or sipping clear broths or plain water. Caffeinated beverages promote fluid excretion so you should avoid them if you have any symptoms of dehydration.
