[cku30301op-3daily103.jpg] Fasting and nadir BGs, 30 April - 7 May 2010
It's quite common for Human-Parents of diabetic dogs to track three glucose readings daily. They check the readings just before feeding in the morning and evening, and also, at the time of day that's usually the dog's lowest reading - called the nadir. Or the trough. Or - the peak! When called the peak, that refers to the time when the insulin is working its hardest.
Alternatively, some people may forgo the fasting readings, and, instead, check the readings just before giving insulin. Or they may take readings just before feeding, and again, very shortly thereafter, just before giving insulin.
The main chart here, above, shows Kumbi's fasting and supposed nadir readings for a week (well, so, eight days!)
Kumbi's nadir (low) time varies, though it's typically around three in the afternoon. It can also be any time until right before his supper in the evening.. Dogs vary in nadir time.
It surely is confusing that nadir (low) time is also called peak time. Sometimes it helps to remind people new to canine diabetes that when called peak time, that refers to the peak of the insulin - working at its hardest - so that the dog's glucose level would be at its lowest for the day.
So, Insulin, Peak, glucose level, nadir.
That spike in the morning, 6:30, really stands out!
In the evening, Kumbi went reasonably low, but stayed there, I thought, longer than he usually does..
The design of this three-daily-readings chart makes it difficult to put the glucose level numbers right into the chart. So, instead, I've included, below, the data table from which the chart above is made.
