The strategy to reduce the dose when a cat is bouncing rarely, if ever, has the desired results. If it were me, I'd be raising the dose.Jill & Alex said:like carolyn, i'm not going to try to convince you to go back to the last good dose. pumbaa is your cat and you've chosen to follow advice given to you, but i hope you don't mind me jumping in here with some thoughts for your consideration...
suze, one of the first things those who are trying to help do is look at "how" the kitty arrived at the current dose. vets are famous for suggesting increases in full units. those are usually the kitties who have the best chance of becoming over dose... that and the ones who were started at too high of a dose to begin with. that's what we look for. edited to add: missed/not taking appropriate reductions can also result in a kitty becoming over dose.Pumbaa said:But with testing (like you do), it is easy to see the difference between a cat which is bouncing and a cat that is OD.
Please tell me how to tell the difference! Has Pumbaa been bouncing or OD'ing? I have no clue at this point.
on a side note: this is where the weight based formula described in the TR protocol comes in handy even if it's simply used as a tool to check to see if the starting dose was set too high. one thing to remember with the weight based formula... ideal weight is used rather than actual weight EXCEPT in the case of an underweight kitty. when a kitty is underweight the actual weight is used to determine the starting dose. kitties with initial starting doses that were too high or who have been increased too quickly or in large increments... these are the kitties who remain at risk for being over dose. their caregivers will sometimes see improvement when dropping the dose when seeing reds or blacks on their spreadsheets.
you did NOT do that with pumba. you mostly traveled up the dosing scale in 0.25 unit increments... except the few "fats" added to the dose. heck, you even went back down to 0.5u and started over again.
pumbaa is a bouncer, that's all. lots of cats are bouncers. pumbaa is not over dose. at this point he's also lacking duration due to the recent dose reductions.
bouncing always gets a bad rap. here's a discussion from one of Jetta's daily threads on bouncing that puts a slightly different slant on the subject: http://www.felinediabetes.com/FDMB/viewtopic.php?f=9&t=55306.
"bounces" from numbers a cat who is not used to being in lower numbers is a very different thing from a cat with very high numbers due to being over dose.
by using the very logical and methodical dosing approach with lantus OR levemir as suggested in the TR protocol... we do not do rebound checks. we shoot right through the bounce... training the liver to eventually accept these lower numbers as "normal". why? because the body has been in high numbers for so long... it forgot what "normal" really feels like. by giving kitty the insulin required to pull the numbers down, we're helping his body "remember" how it feels to be in the normal range. consistency is the key in overcoming the bounces... and it takes time. more time for some kitties than others.
generally speaking, when it's been determined the cat is not over dose (see above), all we see when so called "rebound checks" are done (checking for the possibility of too much insulin) with lantus or levemir kitties is the caregiver finding it necessary to go right back up to the dose they were at weeks or even months later. seems to me it's just a whole lot of wasted time, money, and effort... not to mention the possibility of complications developing along the way from kitty spending more time in hypERglycemia unnecessarily.
ok, so you've previously indicated you're not following the TR protocol, but the premise remains the same.
just some thoughts. i really hate to see you struggling so...

There is a fundamental difference between chronic Somogyi rebound and a bounce. Many of the people who bandy the term "Somogyi" about are actually talking about a bounce. You don't deal with a bounce by reducing the insulin. If you reduce the amount of insulin, you're going to get potentially flatter numbers but they will be high. Once you have a cat sitting in high numbers for an overly long period, you have to deal with glucose toxicity and greater long term risk for organ damage.Although this theory is well known among clinicians and individuals with diabetes, there is little scientific evidence to support it. Clinical studies indicate that a high fasting glucose in the morning is more likely because the insulin given on the previous evening fails to last long enough.[5] Recent studies using continuous glucose monitoring show that a high glucose in the morning is not preceded by a low glucose during the night.[6] Furthermore, many individuals with hypoglycemic episodes during the night don't wake due to a failure of release of epinephrine during nocturnal hypoglycemia.[7] Thus, Somogyi's theory is not assured and may be refuted.
Sienne and Gabby said:Somogyi is a soapbox issue for me. I've researched it. I routinely read clinical research. I have access to both medical and veterinary databases. The strongest statement that can be said about chronic Somogyi rebound is that the original research, which was done in 1938, has never been replicated. At best, the phenomenon is controversial. More likely, it does not exist and has taken on the proportion of urban legend. I have an exceptionally difficult time when people make statements that ignore research evidence and that that happens all the time when it comes to this topic. There is no research data, none, zero, zip, nada that supports the existence of chronic Somogyi rebound in humans and there is even less that addresses Somogyi in cats. And to further ice the cake, the original research was not done with a long acting insulin such as Lantus or Lev. The 1938 study in not generalizable to cats on Lantus.
Sienne and Gabby said:There are phenomena that are unexplained.
The research on Somogyi is bad research. Until someone can reliably prove the phenomenon exists and it can be replicated both inside and outside of the laboratory in humans and/or cats and in those species using long-acting insulin, to call what you're seeing chronic Somogyi rebound is incorrect and perpetuates misinformation.
when following the TR Protocol which is specific about making dose adjustments by using a very systematic and methodical approach... we do not find it necessary or desirable to break patterns by doing rebound checks which only allow a cat to remain in hypERglycemic numbers for weeks or even months. instead, we focus on nadir. the goal is to bring kitty's numbers down as quickly as safely possible.Pumbaa said:Except for the fact that Pumbaa was stuck in pattern that reeked of Somoygi Rebound, and we broke this pattern after decreasing his dose.
I need no additional proof.![]()
Reducing the dose DID break the pattern of lows followed by highs. It put him into a pattern where he is just high all the time, not going low at all. As I mentioned in your one of Pumbaa's condos, it's about knowing what your goals are. If staying high (Pumbaa is mostly above renal threshold) is ok with you, then reducing the dose worked because you're satisfied with the results. If you want to work toward lower numbers, then you have stalled progress quite a bit. Pumbaa was getting green fairly often on 2.25 and fat 2.0, and now a month later you are still working your way back up to get to where you already were (and almost back to fat 2.0 and 2.25).Pumbaa said:Sorry, Sienne, but I know what Pumbaa was experiencing, and know for a fact that reducing his dose stopped the pattern of one day of lows followed by 6 days of highs. This went on for weeks, and it was only after Sheila pointed out the problem that I did more research about Somogyi and I reduced his dose and we broke his previous pattern. As per other posts on this BB where other cats were going through the same thing.
Marje:Marjorie and Gracie said:Sometimes we interpret things on our SSs that just aren't there....I've done it myself; or I've failed to see something that was clear to experienced eyes. I call it my "forest for the trees" perception.
Sienne:Sienne and Gabby said:There are phenomena that are unexplained.
Very well said, Dale. If I could have one day of no stress and get a full night's sleep, I'd probably be thinking a lot clearer and more able to cope with everything. Sorry about hijacking your thread.max&emmasmommie said:Perhaps we are over-thinking this with our need to control what is happening to our cats. They are our children, and we are going to get upset when we can't help them even if it is only for a day. We can experiment and try to stop the problem by doing something some might consider unorthodox when nothing else seems to work, but what we probably need to do for the cat and ourselves is try to relax, regardless of dosage we are using. Dim the lights, put on some calm music or turn everything off, and take a deep breath. Pet your cat. It usually works with babies; why not cats?
The difference with Autumn is that she very likely was over dose. There are lots and lots of hints that Mel is probably missing seeing some low numbers, especially at night. She has probably missed some reductions (in fact there are some missed reductions that you can see on her ss). you are testing enough that you don't need to wonder whether there are low numbers. You would SEE them if they were there. People here used to do rebound checks all the time, but that was also back when the standard advice was to test at preshot every time and do curves sometimes. Testing mid cycle eliminates those kinds of questions.Pumbaa said:190 he had on 6/16) And yes, taking him down to 1.25U on 7/9 didn't help him at all, but it was an experiment worth trying since it was working for Mel's Autumn.
With regard to bouncing and somogyi, regardless of the type of diabetes the cat suffers from the body is not a machine. When a car gets old it burns more oil, so you put a lot more in. Maybe you fix the car and maybe you don't, but it's needs shouldn't fluctuate based on factors you can't determine or understand. That isn't true of the body. I'm afraid that the truth is that the pancreas is like all other organs; it works better at some points and not at others. Unless it doesn't work at all for some reason, it is going to put out varying degrees of insulin, and we are going to see wonky numbers occasionally (or more often) depending on the efficacy. The same is true of the mechanism that allows the cells to get the energy they need. More energy gets in sometimes, for unknown reasons, and the sugar in the blood is lower at times than we would expect.
Perhaps we are over-thinking this with our need to control what is happening to our cats.
Serum glucose, at any single time point during the glucose curve, represents the sum effects in the *rate* and *amount* and *timing* of:
*Exogenous insulin absorption
*Endogenous insulin production
*Intracellular uptake of exogenous and endogenous insulin
*Insulin degradation and elimination - different for exogenous vs endogenous
*Intestinal glucose absorption
*Endogenous glucose production
*Tissue glucose uptake and utilization
and then throw in the amount of exogenous insulin....excess body fat....inflammation....subclinical infection....etc...etc....
I don't like that at all, and unless I can clone myself so I can be in three places at once, I don't know how I'm going to fix this.![]()
