I'm doing my first glucose curve today. I just did a test at 10:20am and it read 1.2 mmol/L. He's on caninsulin and I gave his shot at 8. From what I googled that's a low number but he's acting perfectly fine, no hypo symptoms in the least. The Facebook group advised me he's hypoglycemic so I tested again to make sure I did it properly and it was 1.3. I've given him some food with honey (it's now 11:10, gave him food about 5 min ago). Should I test him again to see if he's higher? Should I be concerned?
 
Yes you should be concerned... as we've been saying on Facebook, this is a very low number and you need to raise it urgently. Cats can hypo without showing symptoms.
High-carb food and honey might raise BG for s short while but you need to monitor very closely and keep testing and give more honey and/or food if necessary to get that number up.

For anyone else looking at this thread, I think this is the situation (Stephanie has also posted on FB).

Stephanie is using a human glucose meter.

No preshot test, 2 units Caninsulin given
+2.3: BG 1.2 mmol/L
+2.6 (?) Food with honey given.
+3 (?) Awaiting BG test...?

Hi there--

Yes, definitely need to keep a close eye (testing every ~20mins until numbers are safely up). Be careful not to feed too much at a time-- adding honey to food is great, it will bring up numbers without filling them up or (hopefully) making them sick like straight honey might.

Thanks, was just about to ask!
 
Would love some advice on insulin dosage. Obviously what were at is too high. Wondering what I should do about tonight. I'll test him before the insulin shot but is there any specific number where you'd suggest I skip the dose?

Until you have lots of BG data from testing and learning your kitty's responses, don't give insulin if BG is under 11 on a human meter or 13 on a pet meter. The 2 unit dose of Caninsulin is too high. We can help you figure out a good dose. Make sure your kitty has no food for at least 2 hours before the pre shot BG test. You need to know what BG is without food to judge whether a dose is safe.

Post here for advice closer to shot time.

Hi Stephanie, I'm copying info that I posted on your FB thread; ....The current insulin dose is definitely TOO HIGH. That low number that you got makes that very clear indeed...

From FB:
"...On FDMB we generally recommend that Caninsulin users who are new to dealing with diabetes (or who don't have a lot of blood test data) aim to not let their cat's blood glucose drop below around 5 - 5.6 mmol as measured on a human glucose meter. That's because Caninsulin can drop the blood glucose very sharply in some cats; and aiming to not let the blood glucose drop below that level gives some buffer of safety while you're getting comfortable with testing, and are gathering data about how your cat responds to insulin (and truly, 'Every Cat Is Different'
1f609.png
).

...FDMB generally recommend to 'newcomers' (or those will little blood testing data) that no insulin is given if the 'pre-shot' blood glucose is below 11 mmol (220 mg/dL). Again, this is an initial safety measure. Once a caregiver has data showing how their own cat responds, this threshold is 'usually' lowered [but not always] "
- - - - -

Well done for today, Stephanie! That must have been quite a stressful experience. (((Hugs))) :bighug:

That dose today caused your kitty's blood glucose to drop too low.
Of course, we don't know what the 'pre-shot' blood glucose level was, so we don't know how much or how fast the blood glucose dropped; we only know that the result was blood glucose that was way too low.

The data shows that the insulin dose does need to be reduced.
What you reduce it to depends, in part, on how well you can monitor your kitty's blood glucose after you give the shot.

I'd suggest that you only give insulin if your kitty's blood glucose prior to the shot is above 11 mmol (200 mg/dL); and I suggest you reduce the current 2 unit dose by half, to one unit only. And further, I'd advise only giving insulin on this occasion if you are able to monitor the blood glucose during the first half of the insulin cycle, and to take any action that may be needed to raise it if it drops too low.
You may well find that the pre-shot blood glucose is high; because that low blood glucose today may have triggered your kitty's body into releasing stored glycogen into the system in order to raise the blood glucose level. This kind of response is quite common. But don't let a high pre-shot number fool you into still giving 2 units. Do keep to the reduced dose. Any high numbers will soon settle out.

This is just my suggestion. Others may have different views.

Again, well done for today. :bighug:

Thank you so much everyone. I would have guessed 11 mmol would be very high and I would have normally given the insulin so that's a surprise to me. I just checked his BG at 5:10pm (I normally feed him at around 6:30pm, insulin at 7) and it was 5.1. I think I'll skip tonight's dose. When should I check him again?

Just for clarification, what is the acceptable range (in mmol) for him? What number should I be aiming for?

I think skipping is in the cards tonight. I'd try 1 unit twice a day beginning tomorrow morning IF his morning BG test is above 11. It's wise to have a little "cushion" at nadir with Caninsulin because it can cause some kitties to dive fast and low. If you can get his BG running between 5 and 8 or so on a human meter that would be good.

If you don't give any insulin then night there's no need to test again until tomorrow morning unless you're curious about where he is around your bed time. If he's still in low-ish numbers, that is good info to have in planning next doses.

Normal on a human meter is 50-120. Until you have more experience and lots of data I would try to have the lowest around 90-100

Seeing up a spreadsheet would be super helpful.

I checked Zoey's bg a half hr after I feed him this morning (it's 8:10 now and I fed him at 7:10) and his BG was 5.0mmol. Why so low? I didn't give him his insulin and I'm feeling so anxious about it. That's 2 times in a row I've skipped his insulin shot. Am I doing the right thing?

That is a perfectly normal number and you do not need to give any insulin. The fact that you had such low numbers when you did give insulin and Zoey's numbers have been normal the last 24 hours without insulin makes me question just how he was diagnosed with diabetes. Can you give more information on how the diagnosis was made?


ETA If you could post more information...how long ago the diagnosis was made..what numbers he had at diagnosis..when insulin was started...type of food you are using etc it would be useful information. When you get time setting up a signature and a spreadsheet will give valuable information

OK. No insulin this morning for sure. We recommend testing BG before you feed him (no food at least 2 hours before this test because you want to know BG without the influence of food).

I was going to ask the same question as Mary Ann (above). Your kitty has normal BG without insulin. Please give us more background info on his diagnosis, etc.

I took him to the vet because he was drinking and peeing excessively which was abnormal for him. They did tests and diagnosed him with diabetes

Did he have any other health issues such as UTI or whatever or was he treated for anything else? Did you have a full blood work and urinalysis done? Do you remember what the glucose levels were at the vet? How long ago was Zoey diagnosed and when did you start insulin? Did you make any food changes since diagnosis.


Sorry for all the questions but just trying to get a fuller picture on the situation. :bighug::bighug:
 
His symptoms disappeared when I started the insulin. Almost immediately actually. So I was convinced that it had to be diabetes...

Here's a plan for you for today: you've already taken one BG reading. How about taking readings every 3 hours or so throughout the day even though he's had no insulin. Get your last one just before his evening meal but make sure he's had no food for at least 2 hours before that test. Keep a list through the day and then post your list here to ask for advice about an evening dose. Does this work for you?

He had urinary issues before the diagnosis and was on Urinary SO for a while before. I originally thought maybe it was an UTI. I can't remember what his BG was but he is also deathly scared of the vet so that was probably a factor in high bg as well.

Just looked at the rceipt for the vet visit and these were the tests they did: blood work + electrolytes, exam, UNA.

Absolutely! I posted below about his diagnosis for more background info as well

I should add that I took him off dry food after the initial diagnosis. He was previously on Urinary SO half dry and half wet. I switched him to DM then switched to fancy feast. We ended up having to drop the dose after we took him off dry food.

We don't know yet but there's a chance that your kitty - if he is truly diabetic - could be one of the lucky diet-controlled ones. We need data over time to figure that out.

OK That would have made a BIG difference in glucose levels. The SO dry food is quite high in carbs and would have caused much higher glucose readings. Usually there is something that "pushed" a kitty into higher glucose numbers...infection, dental issues, underlying diseases or high carb diet. With going back to a low carb wet food that may be all that is needed to get the glucose levels back to normal. Fingers crossed that this is the case with Zoey


ETA It is SO good that you are home testing. Continuing to give shots without knowing about the low glucose levels could have been very dangerous to say the least

I didn't realize how important it was to test until I read these forums. I always thought that if it was so important my vet would tell me but NOPE, I'm glad I came across FDMB. It would be incredible if Zoey was diet controlled. I'll keep you posted! Thanks for your advice.

Your case is the PERFECT example of how important home testing is. By making the decision to home test on your own you could quite literally have saved Zoey's life. There have been a fair number of kitties on this forum that have been able to become diet controlled within a short period of time. Keeping fingers ( and toes) crossed that Zoey will be another one. :bighug: :bighug:
 
Hi everyone, I got my readings for the day and hoping you can help me interpret the results.

Beforehand though Im just wondering if anyone knows anything about the FreeStyle Lite meter. Is it accurate? Just wondering why these numbers are low! Want to make sure I can trust the results. And I'm assuming if the meter beeps and shows a reading then it's got enough blood?

Anyway here are the results from today's testing:
7:40am - 5.0 mmol
12:00pm - 4.7 mmol
4:30pm - 5.7 mmol
6:30pm (just before pm meal) - 5.9 mmol
 
I use the FS Lite as well as the AT2 meter and I have found the readings to be quite good. Yes the meter beeps and displays the reading when you have enough blood. The FS Lite only needs a small amount of blood to read properly. These are not low numbers they are normal numbers. When using a human meter normal numbers will be between 3 and 8 mmol since human meters read a little lower than the pet meter. I am assuming that you have not given any insulin...which is fine..these numbers do not require insulin. Continue doing some more tests and if they continue in this range then your kitty is doing good with the proper diet...ie..no dry food.
 
These are really good BG numbers. No insulin needed - it looks as though the low carb food is doing the trick. I have a Freestyle Lite meter and find that it works well, takes only a tiny drop of blood, etc.
 
Anyway here are the results from today's testing:
7:40am - 5.0 mmol
12:00pm - 4.7 mmol
4:30pm - 5.7 mmol
6:30pm (just before pm meal) - 5.9 mmol

Those numbers are beautiful normal numbers! :D
If he stays in those numbers for 14 days we'd generally consider that he is in remission... (touch wood/anti jinx!)

BTW, Stephanie, is your cat called 'Zoey'?

Yes his name is Zoey. When I got him at 6 months the owners thoughtt he was a girl so they named "her" Zoey. When I took her to get spayed they told me otherwise lol he already knew his name by then so I figured who cares if it's a girls name!

Ah, it's good to know his name. :D

Many years ago we took our kitten, 'Thomas' to the vet for his vaccinations. The vet looked under his tail and then had to write 'Thomasina' on her vaccination card, haha!
'Thomasina' was a bit of mouthful, but it morphed into 'Mossy'. She was adorable.... Still miss her... <sigh>

Stephanie, how is Zoey today?

Thats hilarious! His sugars have been great. Checked this morning amd it was 5.4. Im going to keep testing then let my vet know. Not sure how she'll react, she gave me some attitude when i asked her about home testing, i dont know why. Might have to call her sooner than id like to because his legs are bad again. He had neuropathy when first diagnosed amd they were getting so much better then all of a sudden got bad again. So now im wondering if weve got another issue on our hands. It never ends! Although im more happy about his good sugars so anything else is secondary.
