Diabetes affects both cats and dogs. It is caused by either a lack of insulin (Type I Diabetes) or an inappropriate response to insulin (Type II Diabetes). Insulin is a hormone secreted by the pancreas, which serves to carry glucose into blood cells. When insulin is not being produced or not being utilized correctly, blood sugar begins to rise. Elevated blood sugar levels (hyperglycemia), when left untreated, can be life threatening. Patients can become very ill if diabetes is left undiagnosed, or is poorly managed. Diabetes can be treated with insulin therapy, proper diet, and regular exercise. Regular blood glucose checks are important, to ensure your pet’s diabetes is being management properly.
