What is Glycosuria?
The presence of glucose (the type of sugar used by the body to get energy) is known as glycosuria or glucosuria. When the kidneys filter blood, all the glucose should be reabsorbed and, therefore, there should be no glucose in the urine. However, in cases of renal disease and some systemic diseases such as diabetes, the glucose is not absorbed back into the blood and it is excreted in the urine. Glycosuria is a sign of serious disease and your dog’s veterinarian will need to run various diagnostic tests (e.g. blood and urine tests) to determine what is causing this abnormality.
Types of Glycosuria
Hyperglycemic (excess of glucose in the bloodstream)
- Transient: a temporary increase in glucose in the bloodstream that sometimes occurs due to stress.
- Persistent: an ongoing increase in glucose in the bloodstream that usually occurs due to an underlying illness such as diabetes mellitus.
Normoglycemic (a normal amount of glucose in the bloodstream)
- Congenital: present from birth.
- Acquired: can be due to toxicity.
Causes of Glycosuria In Dogs
- Drugs (e.g. glucocorticoids)
- Toxicity (e.g. antifreeze toxicity)
- Diabetes mellitus
- Central nervous system lesions
- Glucoganoma (tumor of the pancreas)
- Some congenital conditions
- Increased water consumption (polydipsia)
- Increased urination (polyuria)
- Decreased appetite
- Weight loss
- Bad breathe odor (halitosis)
- Recurrent urinary tract infections
- Poor hair conition
Treatment of glycosuria depends on the cause. For example, if your dog suffers from diabetes mellitus, he/she will need insulin and certain diet modifications. On the other hand, if the cause is a toxicity, your dog will need to be hospitalized and receive a detoxification treatment.
