VIPoma   

Overview | Symptoms | Treatment | Prevention

Alternative names:

Vasoactive intestinal peptide-producing tumor; Pancreatic endocrine tumor

Symptoms

  • Watery diarrhea
  • Hypokalemia (low blood potassium) which can cause leg cramps
  • Achlohydria
  • Dehydration
  • Abdominal pain and cramping

Signs and Tests

A VIPoma causes both a high level of VIP in the blood and a high volume of diarrhea, which continues despite fasting. A fast is one way to test for VIPoma.

The physician may also request that the stool be collected and analyzed to determine electrolyte content.

A CT scan or MRI may be ordered to determine the location of the tumor.
