Diabetes mellitus is a disease caused by a deficiency of insulin. Insulin is a hormone produced by the pancreas, and is necessary for body tissues to use blood sugar. Without insulin, sugar remains in the blood and eventually passes into the urine. This causes increased urine production and thirst. Hunger increases because the body cannot use the sugar in the blood. As the disease progresses, chemicals called ketones accumulate, resulting in vomiting and dehydration. Eventually coma and then death occur in untreated animals.
Important Points in Treatment
Blood and urine sugar must be monitored very carefully until your pet's condition is stabilized. Once your pet's insulin requirements are determined and blood-sugar levels are stabilized, only urine sugar needs to be monitored.
