Metastatic insulinoma in dogs: long-term home management
10-year-old Boxer with insulinoma and multiple liver metastases, not a surgical candidate. He has episodes of hindlimb weakness and tremors, mainly after walks and before meals.
Which plan is most appropriate for home management?
chevron_right Show answer and explanation
A. 4–6 small meals a day rich in protein, fat and complex carbohydrates, without simple sugars, with prednisolone, adding diazoxide if that is not enough
Correct. Frequent meals avoid fasting; prednisolone increases gluconeogenesis and antagonises insulin, and diazoxide inhibits its secretion. The aim is to control signs, not to normalise blood glucose.
B. Sugary treats several times a day to keep blood glucose high
Simple sugars sharply raise blood glucose and stimulate excessive insulin release by the tumour, with rebound hypoglycaemia. They are used only to treat an episode, not to prevent one.
C. A single meal a day and periodic fasting to reduce pancreatic stimulation
The tumour secretes insulin autonomously: fasting does not suppress it and is precisely what triggers hypoglycaemic crises.
D. Long, intense daily walks to maintain muscle mass
Intense exercise increases glucose consumption and is a classic trigger for episodes. Moderate, calm activity is recommended.
lightbulb Key takeaway
Teach the owner to recognise hypoglycaemia (weakness, tremors, disorientation, seizures) and to rub glucose syrup on the gums before coming to the clinic. Diazoxide can cause vomiting and anorexia: give it with food. Toceranib is another option in advanced disease.
