Hyperadrenocorticism? Is that even a real word?

What is it?

Hyperadrenocorticism (more commonly known as Cushing’s disease) is an overproduction of cortisol hormone. At normal levels, cortisol helps in response to stress and regulate the immune system. Cushing’s disease is one of the most common endocrine diseases in dogs.

Some common symptoms include:

  • Increased thirstcushings2
  • Increased urination
  • Increased hunger
  • Increased panting
  • Distended abdomen
  • Obesity
  • Loss of hair
  • Muscle weakness and loss
  • Darkening of skin
  • Lack of energy
  • Increased Urine Cortisol:Creatinine Ratios

Not all symptoms are present in every patient and some of these symptoms can also be seen with other diseases. Only your veterinarian can diagnose if your pet has Cushing’s.

There are multiple causes:cushings1

  • Excessive administration of corticosteroid medications.
  • Benign pituitary tumor (rarely can be malignant).
  • Adrenal gland tumor (adrenal-dependent hyperadrenocorticism/ADH).
  • Pituitary-dependent hyperadrenocorticism (PDH) – the body naturally produces too much hormone.

Diagnosis

Your pet’s veterinarian will first take a detailed history and do a complete physical exam. Next step is to perform a full blood chemistry, complete blood count, and urinalysis. These diagnostics will help the veterinarian get a bigger picture of what is happening in the body. Further testing that can help diagnose specific causes include: urine cortisol/creatinine ratio then ACTH stimulation test or Dexamethasone suppression test. The stimulation and suppression tests help determine specifically how much cortisol is being produced and how best it should be treated.

Treatment

  • Excessive administration of corticosteroid medications: Treatment is to slowly wean off the medications according to your veterinarian’s instructions.
  • Benign pituitary tumor and Adrenal gland tumor: First, a metastases check is performed to make sure the tumor has not spread to other organs. Then, a medication is given called trilostane (Vetoryl) to shrink the tumor. Once the tumor has decreased in size, it is removed.
  • Pituitary-dependent hyperadrenocorticism: The pet is put on trilostane for life. This controls the production of cortisol.

Living with Cushing’s Disease

This is a serious disease, but it can be managed if pet owners and veterinarians work together. This is a lifelong diagnosis and does require medications to be given long term. Periodic monitoring will be required to make sure the treatment is going as it should and to help the veterinarians know if an adjustment needs to be made.

The Big Fat Truth About Pet Obesity (and What You Can Do About It)

We all know that face our pets make at us when they want a treat. But let’s stop for a second and think before we give in.

Obesity is a growing epidemic not just for humans but for our furry companions as well; a recent survey done by the veterinary students at University of Georgia showed that 54% of our nation’s pets are overweight or obese. That’s 88.4 million pets!

So keeping this in mind, how will being overweight affect your pet? There are many conditions that can develop from your pet being overweight such as osteoarthritis, decreased stamina, hypertension, diabetes, lipomas (fatty mass), respiratory compromise and most of all it can shorten their life span. Scary stuff right?

Well I know what you’re thinking, “how do I know if my pet is over weight?” Sometimes it can be hard to recognize that your pet is overweight as the weight gain can come on gradually or it is hard to actually accept that your pet is more than just a little chunky and is now fully obese. To assist in this evaluation, body condition scoring has been developed and is fairly easy to accomplish. There is a five-point system (where three out of five is considered optimal). What you want to do is evaluate your pet, feel for a small amount of padding over the ribs. It should be possible to feel the ribs and there should be a small tuck in the belly where the hind legs meet the body. See the graph below.

A question you may be asking yourself is “What can I do to prevent my pet from becoming overweight?” Let start with two words; portion control. Unfortunately, there is no easy way to figure out exactly how much each individual pet should be eating. Determining the correct size for meals depends on the type of food they are fed, how many times a day they eat, their size, their metabolic rate, the amount of exercise they get, and more. To start the process, take a look at the feeding guide on your pet’s food’s label to see how much they should be eating.

dietSo say your pet is already over weight and you’re ready to get some of that extra chunk off your furry friend. This may sound simple, but in fact when one simply tries to cut back on food; it just doesn’t seem to cut it. As with humans, a more formal approach seems to work best. This means feeding a prescription diet made for weight loss (typically “lite” or “less active” diets are meant to prevent weight gain, not actually cause weight loss), exercise, and coming in for regular weigh-ins at the vet’s office.

This means:

  • There must be control over what the pet eats. That’s easy enough if there is only one pet, but trickier if there is more than one pet in the home. Use your ingenuity to feed the pets separately.
  • Feed in meals. Leaving food out encourages snacking. Feeding in meals makes it easier to feed multiple pets different foods or different amounts of food.
  • Commit to regular weigh-ins. Know what the goal weight is and how long it should take to reach this goal/or how to tell if the pet is on target. It is important not to try to go too fast. If the weight loss is not on track, sometimes it is necessary to feed more rather than less. Your veterinarian may need to be in contact with the clinical nutritionists at the pet food company so as to make the best recommendations.
  • Consider interactive toys that can be used when you are not home or where your own participation is minimal.
