| Does my pet have kidney disease?
As our pets grow older, certain health problems are more likely to
arise. One example of this is kidney disease which is particularly common
in middle-aged and older cats.
Both dogs and cats have a pair of kidneys. Each kidney is made up of
millions of tiny units called nephrons which filter the blood, removing
toxic waste products, salts and water. These are then concentrated to form
urine.
Over time, a proportion of the nephrons will disappear and not be
replaced. Other factors such as infections, toxins and cancer may also
destroy nephrons.
However, the kidneys have excess filtering capacity with the result
that the visible symptoms of kidney disease are not seen until
approximately 2/3 of the nephrons have been lost.
At this stage the kidneys start to lose their ability to concentrate
the urine, resulting in large amounts of dilute urine and an increased
thirst.
If the disease continues to progress, toxic waste products start
accumulating in the bloodstream, leading to loss of appetite, weight loss,
weakness, depression, vomiting and poor coat condition.
As you can see the symptoms of kidney disease are unfortunately very
often hidden until the disease is in the very advanced stages. However
with regular veterinary check-ups the symptoms of kidney disease can often
be detected at a very much earlier stage – before they become outwardly
noticeable. As with most illnesses, early detection of kidney disease is
very important.
Whilst kidney disease cannot be cured, a combination of specially
formulated diets (with restricted levels of high quality proteins and
salts) together with new forms of medication, can often significantly
improve the quality of life of pets with this condition.
