I will skip ahead now, but summarize the last few months...
Catcher's insulin dose was increased to 7 units in July. At his one week recheck his BG was 83 so we decreased the insulin back to 6 units twice daily. His weight was up to 41.4 pounds.
Catcher seemed to do well for the next few months. I ordered a glucometer so I could test him at home, though I was still uneducated and did not test him as regularly as I should have been.
At the end of October he was tanking on water again. I tested his blood and it was in the upper 300 range. I was advised to do a glucose curve on him. (Take readings every two hours post injection)
He had his insulin at 7:20.
7 am: 345
9 am: 187
11 am: 220
1 pm: 333
3 pm: High (high on the glucometer means it is over 500)
5 pm: High
Okay so the way it is supposed to work is that the insulin is metabolized at a rate that 6 hours post injection the BG will be at it's lowest point. Catcher was now metabolizing it within 2 hours of his injection. So we switched him to Vetsulin (a porcine insulin). Ideally vetsulin is metabolized slower and only needed every 24 hours, however we were giving it every 12 for Catcher.
Catcher was not responding to the vetsulin at all. I spent the first half of November with him reading over 500. I was getting cranky and worried that nothing was going to be able to help him. After doubling his dose, and still not working, we discovered that Vetsulin is a different concentration (40 units/mL rather than human insulin being 100 units/mL). (I also discovered that human pharmacies are useless). So because I was using the human syringes he was not receiving the correct dose. We promptly changed the syringes and began to see a difference. He still did not react to 6 units however, so we increased his dose to 10 units twice daily.
His peak with 10 units was 73 so we decreased to 9 units.
