Hyperaldosteronism?

Species: Cat
Breed: domestic shorthair
Age: 11-15 years
My niece's 12 yr old cat vomits about every 6 days, gets dehydrated, listless and low body temp. The vet has done xrays, mri, blood & urine testing and maybe more, repeatedly. Everything comes back normal. No blockage, either. In between she acts her normal self. When this happens she gets a potassium IV, wears her little sweatshirt and sleeps on a heating pad or under a blanket. They have tried changing her food but it happens no matter what she eats. This has been going on for 2 months and her vet is at a loss. Any ideas???

Dr. Marie replied:

This is a tough question for me to answer consider that your vet has done so many tests and still doesn't have an answer. I feel for you. I have had cases like this where I have done every test in the book and still couldn't find an answer.

Any time I see an older cat that is quite ill and I can't find an answer on bloodwork or xrays I get concerned about cancer. There are some cancers that can be hard to detect. Some possibilities would be a bone marrow cancer, or even more likely, something like intestinal lymphoma.

Another possibility is a condition that is quite rare called hyperaldosteronism. It is a tumor on an adrenal gland of a cat, but it can often be hard to detect even with very good tests. Cats with this condition can become very weak, have low potassium levels and usually have high blood pressure. This condition can sometimes be cured by surgery, or if surgery is not an option then medications to help fight the low potassium and high blood pressure can be very helpful. There are some specific types of blood tests that can be done to determine if Tyger has hyperaldosteronism. It's worthwhile to ask your vet if this is a possibility.

I wish I had more answers for you, but this is all I can think of at this time.

I hope things improve soon!

Dr. Marie.
