How Diabetic Cats become Non Diabetics

Hello Friend,

Welcome to Tuesday!

My NEW cat Murray was a diabetic..

He was on twice daily insulin.

BUT I did 2 things different

1. STOPPED all kibble, ONLY animal protein- canned, cooked, some raw ( he LOVES raw :-)  )

2. my cat supplement- Ultimate Feline Health Formula. Certain ingredients may help support the pancreas.

How Diabetics become Non Diabetics

A unique feature of diabetes mellitus in cats is that some cats become non-insulin-dependent after treatment has been initiated. From 17% to 67% of cats with diabetes mellitus have been reported to go into spontaneous clinical remission after insulin treatment is initiated.1-4

Diabetic remission is usually defined as normoglycemia that persists for more than four weeks without the use of exogenous insulin,2 although some studies have defined it as euglycemia for only two weeks.5,6 The duration of remission varies, with some cats requiring insulin treatment again within a few weeks to months and other cats remaining in remission for months to years.

Factors that have been hypothesized to influence the likelihood of diabetic remission include the duration of diabetes mellitus, whether the cat initially presented in a ketoacidotic crisis, the carbohydrate content of the diet, the type of insulin used for treatment, the cat’s breed, the presence of underlying disease, and how closely the blood glucose concentration is maintained within the normal range with insulin treatment.

In a study of factors influencing diabetic remission in cats, remission was found to be more likely with increasing age and increasing cholesterol concentration.2 Overall, 21 cats treated with insulin glargine and 23 cats treated with Lente insulin went into remission. A slightly higher percentage of cats (53%) treated with insulin glargine went into remission than cats treated with Lente insulin (47%).

Influence of diet

It has been proposed that low-carbohydrate diets increase the chance of diabetic remission in newly diagnosed diabetic cats. A prospective study comparing a low-carbohydrate, low-fiber diet to a moderate-carbohydrate, high-fiber diet in 63 diabetic cats showed improvements in glycemic control in both groups, but there was a higher rate of remission of diabetes mellitus in the low-carbohydrate, low-fiber diet.6 These findings support the clinical opinion that low-carbohydrate diets in conjunction with good glycemic control increase the likelihood of diabetic remission. If diabetic remission occurs in cats, it is most commonly in the first few months of treatment.

Influence of insulin

It has been shown that strict glycemic control is important in achieving diabetic remission, and it is clear that diabetic cats can go into remission with any insulin (e.g. Lente, protamine zinc [Prozinc—Boehringer Ingelheim Vetmedica], insulin glargine) if good glycemic control is achieved. Many clinicians believe that cats have better glycemic control with long-acting insulins (protamine zinc or insulin glargine), so most clinicians recommend these insulins as the initial insulin choice for treatment in diabetic cats.

It is currently unclear whether some long-acting insulin formulations are more likely to result in remission than others, or whether the critical factor is the glycemic control itself. In a study of 24 newly diagnosed diabetic cats treated with either glargine, protamine zinc, or Lente insulin and fed a low-carbohydrate, high-protein diet, a higher rate of diabetic remission occurred in the cats treated with insulin glargine than in the cats treated with protamine zinc or Lente insulin. However, because of the limitations of this study, further studies in larger groups of diabetic cats are required to confirm this finding.5

Influence of clinical presentation

Although presentation in a diabetic ketoacidotic crisis was thought to occur predominantly in cats with type I diabetes mellitus, suggesting that cats with diabetic ketoacidosis should not go into remission, a recent study documented that some cats that initially presented with ketoacidosis can go into remission with adequate glycemic regulation and control of concurrent illness.9

Other factors

Other factors that have been documented to increase the likelihood of diabetic remission in cats include 1,2

  • A short duration of diabetes mellitus (< 180 days)
  • Administration of glucocorticoids before diagnosis
  • A low insulin dose required to achieve glycemic control
  • A lack of polyneuropathy
  • An older age
  • A lower cholesterol concentration.

P.S.  So Big takeaways from this study include:

1. Best chance of remission comes from diet- High protein, Low Carb,  ..a more 'natural' type diet

2. Great control early on with insulin.

3. Early diagnosis

ALL factors are directly based on YOU the pet owner

P.P.S. My cat supplement is helping support cats with joint issues, maintain a healthy urinary tract, along with supporting the pancreas..

Works very well for Murray!
