Canine and Feline Diabetes mellitus

Diabetes mellitus is a common endocrine disease of dogs and cats. Diabetes is caused by a relative or absolute deficiency of insulin.

Consequences of insulin deficiency

  • Glucose cannot be transported from the bloodstream into the cells
  • Extracellular hyperglycaemia and intracellular hypoglycaemia results - diabetics are always hungry
  • The renal threshold for glucose is exceeded causing osmotic diuresis (polyuria and polydipsia are seen)

For more details see glucose metabolism and pathophysiology of diabetes mellitus.
