Diabetes is caused by a metabolic disorder that affects the regulation of blood sugar levels. As a result, Germans tend to refer to the disorder as "Zuckerkrankheit" (literally "sugar disorder"). Similarly, a literal translation of the term diabetes mellitus is "honey-sweet flow"
and describes the typical symptoms of this metabolic disorder as they have been known since antiquity: Raised blood sugar levels leading to increased excretion of sugar in the urine. This leads to valuable glucose being lost from the body, effectively leading to a reduction in the energy available to the body.
