Insulinoma

A tumour of the pancreas that produces excess insulin. The excess insulin causes blood sugar to fall to dangerously low levels.

Severe🐕 Dogs

This may be a veterinary emergency

URGENT during a low blood sugar crisis (tremors, seizures). On a non-urgent basis, suspect an insulinoma if there are episodes of weakness that improve after eating.

Symptoms to watch for

  • Weakness and disorientation, especially when fasting or after exercise
  • Tremors
  • Seizures
  • Episodes of collapse
  • Symptoms improve after eating something

Causes

A tumour of the insulin-producing cells of the pancreas. Most common in middle-aged to older dogs.

Diagnosis

Blood tests showing low blood sugar together with high insulin at the same time, and an ultrasound scan to locate the tumour.

Treatment

Surgery to remove the tumour when possible. Medical and dietary management (frequent meals) to control the drops in blood sugar. The prognosis depends on how far the disease has spread.

Prevention

Not preventable.
