Subject: [ferrethealth] Diabetes after insulinoma surgery; ferrets on insulin long term
My ferret Chin Soon (5.5 year old spayed female) had insulinoma and
adrenal surgery on Tuesday. Her vet found a small left adrenal tumor
and an insulinoma tumor she described as "huge", "evil", and "very
aggressive". It had grown up against the vena cava. There was also one
smaller nodule on Chin Soon's pancreas. The vet feels she successfully
removed all of the tumor and the nodule.
Chin Soon was recovering well at first. She had post-surgery diabetes
which is something we've seen before. Yesterday things seemed to be
progressing well. Her blood glucose night before last was 400. It
dropped to 280 by yesterday morning and 232 by yesterday evening. Then
things started going backwards. She was up to 320 by yesterday evening
and the levels have kept going up. Her blood glucose this morning was
The vet tells us that in cases like this, after a very large and
aggressive insulinoma tumor is removed, sometimes diabetes is a
permanent but manageable consequence. She is starting Chin Soon on
insulin today and holding her over one more night to see how she
responds. Then Chin Soon will come home but we will have to monitor her
blood glucose regularly and give her a small quantity of insulin daily.
The vet would then recheck her next week.
In previous insulinoma surgeries for our ferrets we've seen very high
blood glucose levels but then they dropped steadily back to normal.
Does anyone have experience with post-surgery diabetes becoming
permanent? If so can you please share your experiences. Has anyone
seen blood glucose drop post surgery then start rising again? If so,
did it ever return to normal without insulin being required long term?
Thanks in advance for any input.
All the best,
Caity and the terrific trio
(Ella, Zephyr, and Chin Soon)
