Diabetic Ketoacidosis (dka)
Tweet Diabetic ketoacidosis (DKA) is a dangerous complication faced by people with diabetes which happens when the body starts running out of insulin. DKA is most commonly associated with type 1 diabetes, however, people with type 2 diabetes that produce very little of their own insulin may also be affected. Ketoacidosis is a serious short term complication which can result in coma or even death if it is not treated quickly. Read about Diabetes and Ketones What is diabetic ketoacidosis? DKA occurs when the body has insufficient insulin to allow enough glucose to enter cells, and so the body switches to burning fatty acids and producing acidic ketone bodies. A high level of ketone bodies in the blood can cause particularly severe illness. Symptoms of DKA Diabetic ketoacidosis may itself be the symptom of undiagnosed type 1 diabetes. Typical symptoms of diabetic ketoacidosis include: Vomiting Dehydration An unusual smell on the breath –sometimes compared to the smell of pear drops Deep laboured breathing (called kussmaul breathing) or hyperventilation Rapid heartbeat Confusion and disorientation Symptoms of diabetic ketoacidosis usually evolve over a 24 hour period if blood glucose levels become and remain too high (hyperglycemia). Causes and risk factors for diabetic ketoacidosis As noted above, DKA is caused by the body having too little insulin to allow cells to take in glucose for energy. This may happen for a number of reasons including: Having blood glucose levels consistently over 15 mmol/l Missing insulin injections If a fault has developed in your insulin pen or insulin pump As a result of illness or infections High or prolonged levels of stress Excessive alcohol consumption DKA may also occur prior to a diagnosis of type 1 diabetes. Ketoacidosis can occasional Continue reading >>
A Respiratory Complication Of Diabetic Ketoacidosis
A 37-year-old man with type 1 diabetes presented with a few days history of persistent vomiting and lethargy associated with thirst and polyuria. He was not on any regular medication apart from insulin. He had omitted his insulin over the last 24 hours. Clinical examination revealed him to be dehydrated with a tachycardia of 120 beats/min and blood pressure 130/80 mmHg. He was dyspnoeic with a respiratory rate of 32 breaths/min; the pattern was characteristic of Kussmauls respiration. Laboratory investigations showed a metabolic acidosis with arterial blood gases pH 7.08, bicarbonate 10.7 mmol/l, base excess -22.6 mmol/l and plasma glucose 32.4 mmol/l. Ward testing for urinary ketones was strongly positive (+++ by ketostix). A chest X-ray was performed (figure). Answers QUESTION 1 The chest X-ray shows mediastinal emphysema with characteristic lines of radiolucency around the mediastinal pleura. There is also radiological evidence of subcutaneous emphysema in the soft tissues in the neck. QUESTION 2 Surgical emphysema is frequently palpable in the neck and may be more widespread involving the face, chest or arm. Hamman's sign is variously described as a crepitous, crackling or crunching sound, synchronous with systole that may be heard with the stethoscope. Pleural effusion may accompany mediastinal emphysema caused by oesophageal rupture. Discussion Pneumomediastinum is a well recognised but infrequent complication of diabetic ketoacidosis.1-4 The incidence of this complication is unknown. In most but not all reports there is a history of persistent or severe vomiting.1 3 The prognosis is excellent and there is prompt regression of the pneumomediastinum following correction of the ketoacidosis.1-3 It is thought that in diabetic ketoacidosis hyperventilation induced by Continue reading >>
Acute Mesenteric Ischaemia: A Thrombotic Complication Of Diabetic Ketoacidosis?
Introduction: Increasing evidence is emerging that demonstrates the increased prothrombotic risk associated with DKA.1 We present the case of a child who developed multiple complications which we believe can be explained by his hypercoaguable state. Case history: A 14-month-old male was admitted in DKA at first diabetic presentation, complicated by cardiovascular shock. Initial blood tests showed blood glucose 80 mmol/l, blood ketones 5.9 mmol/l and venous pH 7.2. He initially responded well to fluid replacement and insulin therapy according to BSPED guidelines, but subsequently developed abdominal distension and fulminant hyperkalaemia (K+10.3 mmol/l). Following stabilisation, laparotomy was performed with excision of 106 cm of necrotic jejunum and formation of a duodenal-ileal anastomosis. Post-operative course was complicated by multi-organ failure, development of arterial and venous femoral vasculature thrombosis, high stoma losses and difficult diabetes control. Despite this the patient survived and was eventually able to be discharged home following reversal of his ileostomy. Conclusions: Acute mesenteric ischaemia (AMI) is a rare complication of DKA. While there are a number of cases described in the adolescent and adult population with long term IDDM2,3, only two cases have previously been described in the literature of children developing AMI at first diabetic presentation4,5. These authors differ in their conclusion as to whether non-occlusive ischaemia or thrombotic causes are responsible for AMI in DKA. We believe our report puts a strong case for a thrombotic aetiology, given the level of hyperosmolarity present in our patient and, more significantly, the concurrent development of arterial and venous thromboses. This also provides a platform for discussion Continue reading >>
What Are The Treatments Of Ketonuria?
If someone has ketonuria from starvation the treatment is giving them something to eat. If a person has ketonuria as a feature of diabetic ketoacidosis the treatment is a little bit of insulin and a lot of hydration. Complicated manipulation of electrolytes also plays a great part of the treatment. It all must be done correctly to bring the patient through. Feel free to treat simple ketonuria as needed. Diabetic ketoacidosis is a emergency medical treatment, and requires removal to a hospital as soon as humanly possible. Continue reading >>
Diabetic ketoacidosis (DKA) is a serious problem that can occur in people with diabetes if their body starts to run out of insulin. This causes harmful substances called ketones to build up in the body, which can be life-threatening if not spotted and treated quickly. DKA mainly affects people with type 1 diabetes, but can sometimes occur in people with type 2 diabetes. If you have diabetes, it's important to be aware of the risk and know what to do if DKA occurs. Symptoms of diabetic ketoacidosis Signs of DKA include: needing to pee more than usual being sick breath that smells fruity (like pear drop sweets or nail varnish) deep or fast breathing feeling very tired or sleepy passing out DKA can also cause high blood sugar (hyperglycaemia) and a high level of ketones in your blood or urine, which you can check for using home-testing kits. Symptoms usually develop over 24 hours, but can come on faster. Check your blood sugar and ketone levels Check your blood sugar level if you have symptoms of DKA. If your blood sugar is 11mmol/L or over and you have a blood or urine ketone testing kit, check your ketone level. If you do a blood ketone test: lower than 0.6mmol/L is a normal reading 0.6 to 1.5mmol/L means you're at a slightly increased risk of DKA and should test again in a couple of hours 1.6 to 2.9mmol/L means you're at an increased risk of DKA and should contact your diabetes team or GP as soon as possible 3mmol/L or over means you have a very high risk of DKA and should get medical help immediately If you do a urine ketone test, a result of more than 2+ means there's a high chance you have DKA. When to get medical help Go to your nearest accident and emergency (A&E) department straight away if you think you have DKA, especially if you have a high level of ketones in Continue reading >>
Type 1 Diabetes Complications
Type 1 diabetes is complicated—and if you don’t manage it properly, there are complications, both short-term and long-term. “If you don’t manage it properly” is an important if statement: by carefully managing your blood glucose levels, you can stave off or prevent the short- and long-term complications. And if you’ve already developed diabetes complications, controlling your blood glucose levels can help you manage the symptoms and prevent further damage. Diabetes complications are all related to poor blood glucose control, so you must work carefully with your doctor and diabetes team to correctly manage your blood sugar (or your child’s blood sugar). Short-term Diabetes Complications Hypoglycemia: Hypoglycemia is low blood glucose (blood sugar). It develops when there’s too much insulin—meaning that you’ve taken (or given your child) too much insulin or that you haven’t properly planned insulin around meals or exercise. Other possible causes of hypoglycemia include certain medications (aspirin, for example, lowers the blood glucose level if you take a dose of more than 81mg) and alcohol (alcohol keeps the liver from releasing glucose). There are three levels of hypoglycemia, depending on how low the blood glucose level has dropped: mild, moderate, and severe. If you treat hypoglycemia when it’s in the mild or moderate stages, then you can prevent far more serious problems; severe hypoglycemia can cause a coma and even death (although very, very rarely). The signs and symptoms of low blood glucose are usually easy to recognize: Rapid heartbeat Sweating Paleness of skin Anxiety Numbness in fingers, toes, and lips Sleepiness Confusion Headache Slurred speech For more information about hypoglycemia and how to treat it, please read our article on hy Continue reading >>

Diabetes Complications In Dogs And Cats: Diabetes Ketoacidosis (dka)
Unfortunately, we veterinarians are seeing an increased prevalence of diabetes mellitus in dogs and cats. This is likely due to the growing prevalence of obesity (secondary to inactive lifestyle, a high carbohydrate diet, lack of exercise, etc.). So, if you just had a dog or cat diagnosed with diabetes mellitus, what do you do? First, we encourage you to take a look at these articles for an explanation of the disease: Diabetes Mellitus (Sugar Diabetes) in Dogs Once you have a basic understanding of diabetes mellitus (or if you already had one), this article will teach you about life-threatening complications that can occur as a result of the disease; specifically, I discuss a life-threatening condition called diabetes ketoacidosis (DKA) so that you know how to help prevent it! What is DKA? When diabetes goes undiagnosed, or when it is difficult to control or regulate, the complication of DKA can occur. DKA develops because the body is so lacking in insulin that the sugar can’t get into the cells -- resulting in cell starvation. Cell starvation causes the body to start breaking down fat in an attempt to provide energy (or a fuel source) to the body. Unfortunately, these fat breakdown products, called “ketones,” are also poisonous to the body. Symptoms of DKA Clinical signs of DKA include the following: Weakness Not moving (in cats, hanging out by the water bowl) Not eating to complete anorexia Large urinary clumps in the litter box (my guideline? If it’s bigger than a tennis ball, it’s abnormal) Weight loss (most commonly over the back), despite an overweight body condition Excessively dry or oily skin coat Abnormal breath (typically a sweet “ketotic” odor) In severe cases DKA can also result in more significant signs: Abnormal breathing pattern Jaundice Ab Continue reading >>
Treatment And Complications Of Diabetic Ketoacidosis In Children And Adolescents
INTRODUCTION Diabetic ketoacidosis (DKA) is the leading cause of morbidity and mortality in children with type 1 diabetes mellitus (T1DM), with a case fatality rate ranging from 0.15 percent to 0.31 percent [1-3]. DKA also can occur in children with type 2 DM (T2DM); this presentation is most common among youth of African-American descent [4-8]. (See "Classification of diabetes mellitus and genetic diabetic syndromes".) The management of DKA in children will be reviewed here (table 1). There is limited experience in the management and outcomes of DKA in children with T2DM, although the same principles should apply. The clinical manifestations and diagnosis of DKA in children and the pathogenesis of DKA are discussed elsewhere. (See "Clinical features and diagnosis of diabetic ketoacidosis in children and adolescents" and "Diabetic ketoacidosis and hyperosmolar hyperglycemic state in adults: Epidemiology and pathogenesis".) DEFINITION Diabetic ketoacidosis – A consensus statement from the International Society for Pediatric and Adolescent Diabetes (ISPAD) in 2014 defined the following biochemical criteria for the diagnosis of diabetic ketoacidosis (DKA) : Hyperglycemia – Blood glucose of >200 mg/dL (11 mmol/L) AND Metabolic acidosis – Venous pH <7.3 or a plasma bicarbonate <15 mEq/L (15 mmol/L) AND Continue reading >>
Patient professional reference Professional Reference articles are written by UK doctors and are based on research evidence, UK and European Guidelines. They are designed for health professionals to use. You may find the Pre-diabetes (Impaired Glucose Tolerance) article more useful, or one of our other health articles. See also the separate Childhood Ketoacidosis article. Diabetic ketoacidosis (DKA) is a medical emergency with a significant morbidity and mortality. It should be diagnosed promptly and managed intensively. DKA is characterised by hyperglycaemia, acidosis and ketonaemia: Ketonaemia (3 mmol/L and over), or significant ketonuria (more than 2+ on standard urine sticks). Blood glucose over 11 mmol/L or known diabetes mellitus (the degree of hyperglycaemia is not a reliable indicator of DKA and the blood glucose may rarely be normal or only slightly elevated in DKA). Bicarbonate below 15 mmol/L and/or venous pH less than 7.3. However, hyperglycaemia may not always be present and low blood ketone levels (<3 mmol/L) do not always exclude DKA. Epidemiology DKA is normally seen in people with type 1 diabetes. Data from the UK National Diabetes Audit show a crude one-year incidence of 3.6% among people with type 1 diabetes. In the UK nearly 4% of people with type 1 diabetes experience DKA each year. About 6% of cases of DKA occur in adults newly presenting with type 1 diabetes. About 8% of episodes occur in hospital patients who did not primarily present with DKA. However, DKA may also occur in people with type 2 diabetes, although people with type 2 diabetes are much more likely to have a hyperosmolar hyperglycaemic state. Ketosis-prone type 2 diabetes tends to be more common in older, overweight, non-white people with type 2 diabetes, and DKA may be their Continue reading >>
Acute Diabetic Ketoacidosis — A Complication Of Intravenous Diazoxide Treatment For Refractory Hypertension
This article has no abstract; the first 100 words appear below. IT has been reported that severe arterial hypertension can be treated effectively and safely with diazoxide given in a series of intravenous injections.1 , 2 During such treatment we have observed the appearance of diabetic ketoacidosis in a nondiabetic patient with impaired renal function. Case Report A 29-year-old woman, previously in good health, was admitted to the University of Wisconsin Hospitals in July, 1966, after the abrupt onset of hematuria, hypertension, oliguria and azotemia. Renal biopsy on the 19th day of oliguria revealed changes consistent with glomerulonephritis. Treatment with azathioprine was begun, and dialytic support continued until the acute renal failure resolved. . . . *From the Renal Section, Department of Medicine, University of Wisconsin Medical Center (address reprint requests to Dr. Updike at the University of Wisconsin Medical Center, Madison, Wise. 53706). We are indebted to Dr. Richard Rieselbach for advice during this study, to Dr. J. M. B. Bloodworth, Jr., for his interpretation of light and electron micrographs and to Dr. Edgar Gordon for the immunoassays for insulin. Continue reading >>

Why Is There Hyperkalemia In Diabetic Ketoacidosis?
Lack of insulin, thus no proper metabolism of glucose, ketones form, pH goes down, H+ concentration rises, our body tries to compensate by exchanging K+ from inside the cells for H+ outside the cells, hoping to lower H+ concentration, but at the same time elevating serum potassium. Most people are seriously dehydrated, so are in acute kidney failure, thus the kidneys aren’t able to excrete the excess of potassium from the blood, compounding the problem. On the other hand, many in reality are severely potassium depleted, so once lots of fluid so rehydration and a little insulin is administered serum potassium will plummet, so needs to be monitored 2 hourly - along with glucose, sodium and kidney function - to prevent severe hypokalemia causing fatal arrhythmias, like we experienced decades ago when this wasn’t so well understood yet. In practice, once the patient started peeing again, we started adding potassium chloride to our infusion fluids, the surplus potassium would be peed out by our kidneys so no risk for hyperkalemia.

As fat is broken down, acids called ketones build up in the blood and urine. In high levels, ketones are poisonous. This condition is known as ketoacidosis. Diabetic ketoacidosis (DKA) is sometimes the first sign of type 1 diabetes in people who have not yet been diagnosed. It can also occur in someone who has already been diagnosed with type 1 diabetes. Infection, injury, a serious illness, missing doses of insulin shots, or surgery can lead to DKA in people with type 1 diabetes. People with type 2 diabetes can also develop DKA, but it is less common. It is usually triggered by uncontrolled blood sugar, missing doses of medicines, or a severe illness. Continue reading >>
Diabetic Ketoacidosis: A Serious Complication
A balanced body chemistry is crucial for a healthy human body. A sudden drop in pH can cause significant damage to organ systems and even death. This lesson takes a closer look at a condition in which the pH of the body is severely compromised called diabetic ketoacidosis. Definition Diabetic ketoacidosis, sometimes abbreviated as DKA, is a condition in which a high amount of acid in the body is caused by a high concentration of ketone bodies. That definition might sound complicated, but it's really not. Acidosis itself is the state of too many hydrogen ions, and therefore too much acid, in the blood. A pH in the blood leaving the heart of 7.35 or less indicates acidosis. Ketones are the biochemicals produced when fat is broken down and used for energy. While a healthy body makes a very low level of ketones and is able to use them for energy, when ketone levels become too high, they make the body's fluids very acidic. Let's talk about the three Ws of ketoacidosis: who, when, and why. Type one diabetics are the group at the greatest risk for ketoacidosis, although the condition can occur in other groups of people, such as alcoholics. Ketoacidosis usually occurs in type one diabetics either before diagnosis or when they are subjected to a metabolic stress, such as a severe infection. Although it is possible for type two diabetics to develop ketoacidosis, it doesn't happen as frequently. To understand why diabetic ketoacidosis occurs, let's quickly review what causes diabetes. Diabetics suffer from a lack of insulin, the protein hormone responsible for enabling glucose to get into cells. This inability to get glucose into cells means that the body is forced to turn elsewhere to get energy, and that source is fat. As anyone who exercises or eats a low-calorie diet knows, fa Continue reading >>
Ketoacidosis: A Diabetes Complication
Ketoacidosis can affect both type 1 diabetes and type 2 diabetes patients. It's a possible short-term complication of diabetes, one caused by hyperglycemia—and one that can be avoided. Diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS) are two of the most serious complications of diabetes. These hyperglycemic emergencies continue to be important causes of mortality among persons with diabetes in spite of all of the advances in understanding diabetes. The annual incidence rate of DKA estimated from population-based studies ranges from 4.8 to 8 episodes per 1,000 patients with diabetes. Unfortunately, in the US, incidents of hospitalization due to DKA have increased. Currently, 4% to 9% of all hospital discharge summaries among patients with diabetes include DKA. The incidence of HHS is more difficult to determine because of lack of population studies but it is still high at around 15%. The prognosis of both conditions is substantially worsened at the extremes of age, and in the presence of coma and hypertension. Why and How Does Ketoacidosis Occur? The pathogenesis of DKA is more understood than HHS but both relate to the basic underlying reduction in the net effective action of circulating insulin coupled with a concomitant elevation of counter regulatory hormones such as glucagons, catecholamines, cortisol, and growth hormone. These hormonal alterations in both DKA and HHS lead to increased hepatic and renal glucose production and impaired use of glucose in peripheral tissues, which results in hyperglycemia and parallel changes in osmolality in extracellular space. This same combination also leads to release of free fatty acids into the circulation from adipose tissue and to unrestrained hepatic fatty acid oxidation to ketone bodies. Some drugs ca Continue reading >>
