Insulinomas ----------- General Information An insulinoma is a rare tumor of the pancreas of dogs and cats. These tumors release large amounts of insulin and cause a severe decrease in blood sugar (glucose) levels. Low blood sugar levels rapidly cause abnormal brain activity, leading to incoordination, weakness, collapse, muscle twitching, blindness, depression, extreme hunger and seizures. The cause of these tumors is unknown. Important Points in Treatment 1. Surgical removal of the tumor is the best treatment. If the tumor occupies a large portion of the pancreas, or if it has spread to other areas, complete removal may not be possible. 2. Some patients with inoperable tumors can be maintained in reasonable health with dietary therapy and medication. 3. Inflammation of the pancreas is common after surgery. Hospitalization is often necessary for several days after surgery. 4. Blood sugar levels must be monitored closely during both medical and surgical treatment. 5. Give all the medication as directed. Call the doctor if you cannot perform any prescribed treatment. 6. Diet: Diet is important in both surgical and non-surgical patients. Feed as follows: 7. Activity: Exercise decreases blood sugar levels. Because insulin is still being released by the tumor, blood sugar levels may rapidly decrease during and after exercise. Allowable exercise includes: Notify the Doctor if Any of the Following Occur: * Your pet's signs continue or worsen. * Your pet refuses to eat. * Your pet seems to have abdominal pain. * Your pet's general well-being declines. * Your pet is depressed or vomits.
