Yes, this is true. I sent the following directly to Mary, and with Dr. Murray's permission, I'm posting his comments on chromium/brewer's yeast usage with hypoglycemic ferrets so everyone can benefit. This originally appeared in the FAIML (Ferret Adrenal/Insulinoma Mailing List)... --------------------------- From veterinarian, Jerry Murray: It sounds like there is still some confusion about chromium, how it works, and what "helps to regulate blood glucose levels " actually means. Chromium is an essential trace element. Chromium supplementation is often recommended for people and pets (dogs and cats) with diabetes. Diabetics are basically the opposite of insulinoma ferrets because diabetics have a high blood glucose (sugar) level. Chromium helps to lower their high blood glucose levels. This is where the phrase "helps to regulate blood glucose levels" comes from. Chromium also has insulin like action that helps to increase muscle mass and decrease body fat and weight. This is also a good thing for diabetics, and the reason chromium is often used as a weight loss agent. On the other hand, the goal of medical therapy for an insulinoma ferret is to raise the blood glucose level. Clearly it does not make sense to give chromium that will lower an already low blood glucose level, nor does it make sense to give chromium that has insulin like properties when there is already too much insulin being produced by the insulinoma. Remember medical therapy is a combination of 3 things: DIET, PEDIAPRED, and PROGLYCEM. The DIET needs to be a high quality, high meat-based ferret food or kitten food. Cooked meats (beef, chicken, turkey, fish), cooked eggs, Gerber's chicken baby food, Hill's A/D and/or Eukanuba's feline maximum calorie can all be used as supplements, treats, and when the ferret is anorectic. A/D, baby food, and maximum calorie can be syringed fed when needed. The extra protein provides both amino acids and a substrate for glucose production by the liver (gluconeogenesis). Perhaps the ideal diet would have (on a dry matter basis) 55-60% protein, 20-30% fat, and <10% carbo- hydrates. This is close to what "Bob's chicken gravy" has. However I totally disagree with adding brewer's yeast or chromium to it! PEDIAPRED helps to raise blood glucose levels, inhibits utilization of glucose, and has some antiinsulin activity. This is why pediapred is the first medicine used to treat insulinoma ferrets. PROGLYCEM helps to raise blood glucose levels by lowering the amount of insulin secreted by the pancreas. Due to its high cost and bad taste, it is usually added when pediapred is no longer able to control the blood glucose levels. Remember chromium does not raise blood glucose levels. It lowers the blood glucose levels, so I would not give it to an insulinoma ferret.
