Diabetes

Excessive thirst and increased urination are classic diabetes symptoms. When you have diabetes, excess sugar (glucose) builds up in your blood. Your kidneys are forced to work overtime to filter and absorb the excess sugar. If your kidneys can't keep up, the excess sugar is excreted into your urine, dragging along fluids from your tissues. This triggers more frequent urination, which may leave you dehydrated. As you drink more fluids to quench your thirst, you'll urinate even more. Also, you may feel fatigued. Many factors can contribute to this. They include dehydration from increased urination and your body's inability to function properly, since it's less able to use sugar for energy needs. Diabetes symptoms sometimes involve your vision. High levels of blood sugar pull fluid from your tissues, including the lenses of your eyes. This affects your ability to focus. Doctors and people with diabetes have observed that infections seem more common if you have diabetes.  It may be that high levels of blood sugar impair your body's natural healing process and your ability to fight infections. Diabetes may weaken your ability to fight germs, which increases the risk of infection in your gums and in the bones that hold your teeth in place. Your gums may pull away from your teeth, your teeth may become loose, or you may develop sores or pockets of pus in your gums — especially if you have a gum infection before diabetes develops.  If you have diabetic nerve damage, which is called neuropathy, you could have an infected cut, scratch, or skin puncture and not know it.
