Pets Get Diabetes Too
Author: Nick Carmichael
Just like humans pets can suffer from diabetes mellitus too. By a simple
blood test, called fructosamine, they can be diagnosed and then, under the care of your veterinary surgeon,
often treated succesfully.

Fructosamines are stable complexes of carbohydrates and proteins that are produced by an
irreversible, non-enzymatic glycosylation of serum proteins. Fructosamine (glycated serum protein) measurements
are useful in diagnosing and monitoring diabetes mellitus in both cats and dogs.
The test is highly sensitive and can be used to distinguish non-diabetic transiently
hyperglycaemic cats from diabetics with chronic hyperglycaemia. A single measurement of fructosamine indicates
the average glucose concentration over the previous 1-3 weeks and its assay can therefore be used to assist in
the diagnosis of diabetes mellitus as well as monitoring the effectiveness of insulin therapy in diabetic
patients.
Fructosamine values are not influenced by acute fluctuations in blood glucose making them more
useful than single glucose measurements taken from stressed or anorexic patients, or animals on glucose
containing IV fluids.
In some cases however they can be used in conjunction with serial glucose curves to assess the
short and long term response to insulin administration.
Please contact your veterinary surgeon for further details or if you have any concerns about
your pets.
