Ideal Blood Glucose Curve (mg/dl)

Ideal blood glucose curve in a treated diabetic cat. Insulin was administered at 8am.

Normal blood glucose in non-diabetic cats ranges from about 70 - 170 mg/dl.
The renal threshold is about 250mg/dl.

The goal is to produce a blood glucose curve that approaches the reference range but avoids potentially fatal hypoglycaemia - for example 90 - 200 mg/dl for most of each 24 hour period.

This is a representation of an IDEAL glucose curve - just a goal. . In the real World, you are quite unlikely to achieve such a curve. Be quite thankful if your results are anything close. This is a representation of a cat that received one insulin injection only (at 8 in the morning). Your cat is likely to need two insulin injections - a second one in the afternoon or evening as it blood insulin level creeps up again.. So at the time of the second injection, the graph should repeat. The graph will also be influenced by your cat's feeding schedule.

Non-diabetic cats do not have as pronounced, undulating (up-and-down) curves. That is because their pancreas releases small amounts of insulin continuously - in response to their body's needs. That keeps their blood glucose level in a more steady state.
