Once you have your diabetic pet regulated on insulin it’s smooth sailing, right? Well, not necessarily. Even a well-regulated diabetic doggie may mischievously get into the trash and subsequently vomit. Or Fluffy might toss up a random hair ball. Just because your pet is diabetic doesn’t mean it can’t have a dietary indiscretion or gastroenteritis the same as non-diabetic pets!
Even if you are new to having a diabetic pet, if you understand the basics of diabetes (most importantly that insulin drops the blood sugar levels) you can work your way through a short-term treatment plan. You know that insulin allows sugar (from the food we eat) to enter our cells. Without food, giving the usual dose of insulin could drop the blood glucose to dangerously low levels. However, if the blood glucose is still quite elevated, you might consider giving a lesser dose of insulin even if a diabetic won’t eat. You know your pet… Some have a sensitive stomach whereas others might have the constitution as sturdy as a goat. Some have ravenous appetites whereas other pets may be finicky. None of us have a crystal ball when it comes to predicting if a pet will vomit more.
Not eating and vomiting are both situations that put us in the same boat in regards to insulin dosing. No food in the tummy means there is nothing for the insulin to utilize. Of course, vomiting is worse than simply not eating because we don’t know why the pet is nauseous nor if there will be more vomiting to follow. Not eating may simply be that a pet isn’t hungry.
Obviously you need a good relationship with your veterinarian to help you work through contingency plans for these situations, but I want you to understand in general what we might do. Of course making choices to alter the insulin dose mandates that you have a blood glucose meter at home. I think the vast majority of our readers do have a blood glucose meter for their pets. You likely use it to run periodic blood glucose curves so that you and your vet can evaluate your pet’s insulin dose and recommend the usual insulin dose for your pet. However, if your pet doesn’t eat or if your pet eats and then vomits, you can use the meter to run a spot check of the blood glucose.
Here’s where the tricky part comes in: Just how much less insulin shall we give if a pet doesn’t eat or if a pet vomits? This depends on the pet’s blood glucose. If the blood glucose is sky high in the 400s or more, you might give half the regular dose even if the pet is vomiting or not eating. If the blood glucose is normal or only mildly elevated you would clearly skip the insulin dose. In between I’d advise you to be very cautious with insulin doses. As a short period of a high blood glucose level is much safer than a short period of a low blood glucose level! Contact your veterinarian. And if the anorexia or vomiting persist until the next dose, you better get your pet into the vet office pronto.
Years ago when I was an ER vet, I recall numerous times when clients got confused as to course of action for a diabetic pet who was vomiting or not eating. I recall several times when clients gave their diabetic pets extra insulin in these situations instead of backing off on the dosage. Don’t be that pet owner. If you have any doubt, contact your veterinarian. Otherwise you may just end up with a pet in a hypoglycemic crisis, hospitalized on IV fluids spiked with dextrose.
