Diabetes

Diabetes is generally used synonymously to mean diabetes mellitus. However,
the condition means literally "passing too much urine". It comes from the
Greek word meaning to 'pass over' or 'cross over'. There are two forms of
diabetes, namely diabetes mellitus and diabetes insipidus. By far the most
common form of diabetes is diabetes mellitus. Increased amounts of urination
are common to all forms of diabetes. Frequency (of urination), nocturia and
thirst are other common symptoms.

If a person with diabetes is found unconscious, a very likely cause is
diabetic coma which is a medical emergency.
