Ketones — The 6 Must-knows

WRITTEN BY: Kyla Schmieg, BSN, RN Editor’s Note: Kyla Schmieg (BSN, RN) is a practicing pediatric endocrinology nurse in Cincinnati, OH, USA, and Type 1 Diabetic, working on the same unit she was diagnosed at 26 years ago. 1 – What are ketones? Ketones are chemicals that build up when your body starts to burn fat for energy. The most common cause of ketones in diabetics is insulin deficiency. Without enough insulin, glucose builds up in the blood stream and can’t enter cells. The cells then burn fat instead of glucose. This results in ketones forming in the blood and eventually spilling into urine. 2 – Why can ketones be dangerous? Having ketones can indicate that your body needs more insulin. (Always monitor your blood sugar levels to know how much insulin you need.) If you have a build up of ketones, this can lead to Diabetic Ketoacidosis (DKA). Signs of DKA include moderate or large ketones, nausea, vomiting, abdominal pain, fruity or acetone (think nail polish remover) breath, rapid breathing, flushed skin, and lack of energy. If left untreated, it can lead to a serious and life-threatening diabetic coma or death. High levels of ketones are toxic to the body and if you Continue reading >>

    I recently got the flu and was feeling awful with a temperature and all the fun that comes with it!. I knew I had to keep eating and taking in fluids though. I could barely get out of bed but I did what I had to. On the 3rd day in the night I checked and found I had high levels of ketones in my urine but in my blood it was 0.9. I checked again a little while later and it was 1.1 in my blood. Then 1.4. My sugars weren't too bad. As the ketones were rising and it was getting later I was worried at what point I would need help. The rule of thumb being getting advice at 1.5 and above and if higher and vomiting then going to A & E.
    I rang 111 as I didn't have anywhere else I could ring at that time. Then a paramedic phoned back to chat. She felt a dr was needed. A dr came round and said Id done the right thing. He found I had a UTI so prescribed antibiotics straight away.
    I was in a state but he said the ketones didn't concern him at this point particularly as they'd come down a bit since he arrived. Down to 1.1.
    He was very kind.
    I have since been in touch with my diabetic nurse during work hours and we have an appointment soon. She told me to check my pump Manual for sick days. I did and can't find any mention of ketones with normal blood sugars.
    She told me the treatment is the same. Go to hospital, get put on a glucose drip and double the insulin.
    We are 3 weeks on and I still have the tail end if this horrible flu virus thing. I live with ME and fibromyalgia too.
    I would rather avoid hospital at all costs. Last time I went in years ago for unrelated reasons I had to get my own blankets and meds back to deal with myself. I prefer to feel in some semblance of control in my own home than relying on others.
    What I'd like to know is others experiences and knowledge. Thanks

    My sugars weren't too bad. What's not too bad? Hyperglycemia can result in excess ketone production starting at 13.3.
    There can be a fairly big delay between hyperglycemia and urine ketones ... maybe there's a similar delay with blood ketones? I had an 18.5 spike during the afternoon while at the GP's office with only "small" amounts of ketones in my urine, but measured "large" amounts of ketones in the evening when my blood sugar was already down to 10-11.
    Maybe you missed a spike in your blood sugar, but caught the after-effects in your ketones?

I prefer to feel in some semblance of control in my own home than relying on others. I have ME/CFS too, and totally understand where you're coming from. I stayed home with a likely case of lactic acidosis induced by metformin, because I felt way too sick to deal with calling anyone or going anywhere, much less a hospital. Probably wasn't thinking too clearly either, due to the severe acid-frying-my-brain headache that came with it
    But the noise, the lights, the food, uncomfortable beds ... it would be torture.

    My bloods were between 5 and 11... got to 13 at one point but I also didn't want to go hypo when I was sick at one point. I got very shaky and weak and hot.... I always got told that blood ketone testing was what was going on currently so more correct where as urine test was hours behind .
    There doesn't seem to be much information about this

    Finding glucose in the urine of someone who has not yet been diagnosed will sometimes be a tip-off that they have developed diabetes, but glucose doesn’t appear in the urine unless the blood sugar is around 240 or even higher for many people, so there is no real reason to test the urine for sugar because it isn’t helpful in managing your diabetes if all you know is that you are roughly under 240. On the other hand, ketones in the urine is a s ...

The A1C test is sometimes called the hemoglobin A1c, HbA1c, or glycohemoglobin test. The A1C test is the primary test used for diabetes management and diabetes research. How does the A1C test work? The A1C test is based on the attachment of glucose to hemoglobin, the prot ...

  • How Are Ketones Measured In Urine

    An important aspect of the Ketogenic Diet is knowing how high your ketone levels are. There are three types of Ketones; beta-hydroxybutyrate (BOHB) which is measured in the blood, acetoacetate (AcAc) which is typically measured in the urine, and acetone which is typically measured in the breath. Measuring Acetone in the breath is becoming a good option, and I believe that this is probably the future of ketone measurement. It's an area of rapid de ...

  • Ketones In The Urine Kidney Failure

    A dog with a high level of ketones in his urine suffers from a condition known as ketonuria, usually resulting from a buildup of these substances in the dog's blood. A ketone is a type of acid, which, if allowed to accumulate in the blood, can lead to ketoacidosis, a potentially fatal condition. The main health conditions that can cause high ketone levels in a canine are starvation and diabetes. A dog's body breaks down the food that he eats into ...

  • What Does It Mean When You Have Ketones In Your Urine?

    Urine tests may be done in people with diabetes to evaluate severe hyperglycemia (severe high blood sugar) by looking for ketones in the urine. Ketones are a metabolic product produced when fat is metabolized. Ketones increase when there is insufficient insulin to use glucose for energy. Urine tests are also done to look for the presence of protein in the urine, which is a sign of kidney damage. Urine glucose measurements are less reliable than b ...
