This post is meant to familiarize everyone with what pancreatitis, colitis and diabetes really mean.
(from http://www.mayoclinic.com/health/pancreatitis/DS00371 and http://www.petdiabetes.com/pdorg/pancreatitis.htm)
Pancreatitis means inflammation of the pancreas. The pancreas produces enzymes that help digestion and hormones that help regulate the way your body processes sugar (or glucose). The inflammation can become severe, and the digestive enzymes that are normally inactive can become active and these enzymes then can cause damage to the pancreas. This causes a cycle of increasing inflammation. The vet thinks Buzz has chronic pancreatitis, or essentially scar tissue has formed in his pancreas, which in turn decreases the ability of his pancreas to function properly, and therefore diabetes can (and did) result.

Colitis refers to an inflammation of the colon and is often used to describe an inflammation of the large intestine (colon, caecum, and rectum). We think this is a separate medical condition than the pancreatitis/diabetes. This may be one of the causes that his diabetes got so out of control, though.

Diabetes is a disease in which the body doesn't produce or properly use insulin. Insulin is a hormone produced in the pancreas. Insulin is needed to turn sugar and other food into energy. Buzz doesn’t make enough insulin because of the scarring of his pancreas. This causes sugars to build up too high in his blood. Diabetes mellitus is defined as a fasting blood glucose (or the blood glucose when Buzz isn't eating) of 126 milligrams per deciliter (mg/dL) or more.
To give you an idea of how bad Buzz's diabetes is/was, these are his glucose readings since we picked him up on Thursday night, December 9, 2010. Please keep in mind that after each reading, we administered the proper amount of insulin - usually after texting the internal specialist to get his thought on how much insulin to give (humulin-r initially, then switched to humulin-n after the second reading on Sunday, each was measured in mg/dL)
