Hi, Linda is away for the day.
Dosing is based on how low a cat goes during a cycle and not on the preshot numbers. Testing at preshot is to determine whether or not the numbers are high enough to shoot.
Your cat is bouncing from the low numbers yesterday. It's body sees low numbers that it is not used to as a crisis and reacts accordingly. This is called a bounce.
Definition of bouncing:
- Bouncing - Bouncing is simply a natural reaction to what the cat's system perceives as a BG value that is "too low". "Too low" is relative. If a cat is used to BGs in the 200's, 300's, or higher for a long time, then even a BG that drops to 150 can trigger a "bounce". Bouncing can also be triggered if the blood glucose drops too low and/or too fast.The pancreas, then the liver, release glucogon, glycogen and counter-regulatory hormones. The end result is a dumping of "sugar" into the bloodstream to save the cat from going hypoglycemic from a perceived low. The action is often referred to as "liver panic" or "panicky liver". *Usually*, a bounce will clear kitty's system within 3 days (6 cycles).
The only thing you can do is wait it out. Varying the insulin dose not not work. Insulin is a hormone, not a drug. Giving a second shot is like giving a double dose.
The 44 on an AlphaTrak was far too low. Even though you are seeing high numbers this morning, the 44 tells us that the current dose is too high and double dosing because of the high preshot numbers is dangerous.
Test and feed as normal. Hopefully, someone with firsthand Prozinc knowledge will be online before your PMPS shot time.
It would help tremendously if you could set up a spreadsheet and a signature. We are pretty data oriented here. In a crisis like last night, it helps if all the information is on the spreadsheet and the signature. The forum can be a busy place sometimes and it uses up precious time trying to find the history. If you need help setting these up, just holler. There are a number of people who can do it quickly.
As regards to the Somogyi Effect - the research for it just isn't there.
