Normal dosing is to do every 12 hours, as usual, sometimes with a reduced dose if they test lowish, as they may be more sensitive to insulin after a hypo.
The high you are seeing is due to having gone so low; she is 'bouncing' due to the kickback of compensatory hormones releasing glycogen, a form of stored sugar.
We have a specific protocol for managing low numbers/hypo situations, linked in the following glucose reference ranges
Here are some glucose reference ranges used for decision making using glucometers. Human glucometer numbers are given first. Numbers in parentheses are for non-US meters. Numbers in curly braces are estimates for an AlphaTrak.
< 40 mg/dL (2.2 mmol/L) {< 70 mg/dL for an AlphaTrak}
- Treat as if
HYPO if on insulin
- At nadir (lowest point between shots) in a long term diabetic (more than a year), may earn a reduction.
< 50 mg/dL (2.8 mmol/L) {< 80 mg/dL for an AlphaTrak}
- If before nadir, steer with food, ie, give modest amounts of medium carb food to keep from going below 50 (2.8).
- At nadir, often indicates dose reduction is earned.
50 - 130 mg/dL (2.8 - 7.2 mmol/L) {80 - 160 mg/dL for an AlphaTrak}
- On insulin - great control when following a tight regulation protocol.
- Off insulin - normal numbers. (May even go as low as the upper 30s (1.7 mmol/L){60s for an AlphaTrak}; if
not on insulin, this can be safe.
= 150 mg/dL (8.3 mmol/L) {> 180 mg/dL for an AlphaTrak}
- the lowest level pre-shot for ProZinc, PZI, or other non-depot insulins.
> 150 mg/dL (8.3 mmol/L) {> 180 mg/dL for an AlphaTrak}
- At nadir, indicates a dose increase may be needed when following a tight regulation protocol.
200 mg/dL (11.1 mmol/L) {230 mg/dL for an AlphaTrak}
- no shot level for beginners; may slowly reduce to 150 mg/dL (8.3 mmol/L) {180 mg/dL} for long-acting insulins (Lantus, Levemir, and ProZinc) as data collection shows it is safe
180 - 280 mg/dL (10 - 15.6 mmol/L) {may be 210 - 310 mg/dL for an AlphaTrak}
- Any time - The renal threshold (depending on data source and cat's renal function) where glucose spills into the urine.
- Test for ketones, glucose is too high.
>= 280 mg/dL (15.6 mmol/L) {may be >=310 mf/dL for an AlphaTrak},
if for most of the cycle between shots
- Uncontrolled diabetes and thus at risk for diabetic ketoacidosis and hepatic lipidosis
- Follow your insulin protocol for dose adjustments
- Test for ketones;
if more than a trace level of ketones, go to vet ASAP.
