Also known as: diabetes
Motnja uravnavanja glukoze zaradi pomanjkanja inzulina ali odpornosti nanj.
Diabetes mellitus arises when insulin is deficient or ineffective, so glucose cannot enter cells and accumulates in the blood. It is a common endocrine disease of middle-aged and older cats.
In cats the disease typically reflects insulin resistance combined with failing insulin-producing cells, driven largely by obesity, inactivity and sometimes other hormonal disorders or medications such as steroids.
Owners notice increased thirst and urination, weight loss despite a good appetite, and lethargy. Some cats develop a plantigrade stance due to nerve damage. Severe cases show vomiting and collapse from ketoacidosis.
Persistently elevated blood glucose with sugar in the urine confirms diabetes, supported by a fructosamine test that reflects longer-term control and rules out stress-related spikes.
Most cats need insulin injections, usually twice daily, alongside a low-carbohydrate diet and weight management. Home glucose monitoring guides dosing. Early intensive control can lead to remission.
Maintaining a lean body weight, encouraging activity and feeding appropriate diets greatly reduce the risk of diabetes in cats.
