Effects of diet on glucose control in cats with diabetes mellitus treated with twice daily insulin glargine

Abstract

The purpose of this study was to evaluate the effects of dietary modification in addition to twice daily insulin glargine. Cats were treated with insulin glargine twice daily and randomized to receive either a low carbohydrate, high protein (LCHP) diet ( n=6) or a control diet ( n=6) for 10 weeks. Re-evaluations of clinical signs, blood glucose curves, and serum fructosamine concentrations were performed at weeks 1, 2, 4, 6, and 10. Two of 12 cats achieved complete remission by the end of the study but remission rate was not different between diet groups. Using twice daily insulin glargine and frequent monitoring, all cats in both diet groups achieved successful glycemic control. Frequent monitoring is key to achieving glycemic control in diabetic cats; potential benefits of dietary modification require further evaluation.
