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:[1] 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.[2] 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.[2] 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 >>

Diabetic Ketoacidosis In Dogs

Diabetic Ketoacidosis In Dogs

My dog is diabetic. He has been doing pretty well overall, but recently he became really ill. He stopped eating well, started drinking lots of water, and got really weak. His veterinarian said that he had a condition called “ketoacidosis,” and he had to spend several days in the hospital. I’m not sure I understand this disorder. Diabetic ketoacidosis is a medical emergency that occurs when there is not enough insulin in the body to control blood sugar (glucose) levels. The body can’t use glucose properly without insulin, so blood glucose levels get very high, and the body creates ketone bodies as an emergency fuel source. When these are broken down, it creates byproducts that cause the body’s acid/base balance to shift, and the body becomes more acidic (acidosis), and it can’t maintain appropriate fluid balance. The electrolyte (mineral) balance becomes disrupted which can lead to abnormal heart rhythms and abnormal muscle function. If left untreated, diabetic ketoacidosis is fatal. How could this disorder have happened? If a diabetic dog undergoes a stress event of some kind, the body secretes stress hormones that interfere with appropriate insulin activity. Examples of stress events that can lead to diabetic ketoacidosis include infection, inflammation, and heart disease. What are the signs of diabetic ketoacidosis? The signs of diabetic ketoacidosis include: Excessive thirst/drinking Increased urination Lethargy Weakness Vomiting Increased respiratory rate Decreased appetite Weight loss (unplanned) with muscle wasting Dehydration Unkempt haircoat These same clinical signs can occur with other medical conditions, so it is important for your veterinarian to perform appropriate diagnostic tests to determine if diabetic ketoacidosis in truly the issue at hand Continue reading >>

Ketosis Vs. Ketoacidosis: What You Should Know

Ketosis Vs. Ketoacidosis: What You Should Know

Despite the similarity in name, ketosis and ketoacidosis are two different things. Ketoacidosis refers to diabetic ketoacidosis (DKA) and is a complication of type 1 diabetes mellitus. It’s a life-threatening condition resulting from dangerously high levels of ketones and blood sugar. This combination makes your blood too acidic, which can change the normal functioning of internal organs like your liver and kidneys. It’s critical that you get prompt treatment. DKA can occur very quickly. It may develop in less than 24 hours. It mostly occurs in people with type 1 diabetes whose bodies do not produce any insulin. Several things can lead to DKA, including illness, improper diet, or not taking an adequate dose of insulin. DKA can also occur in individuals with type 2 diabetes who have little or no insulin production. Ketosis is the presence of ketones. It’s not harmful. You can be in ketosis if you’re on a low-carbohydrate diet or fasting, or if you’ve consumed too much alcohol. If you have ketosis, you have a higher than usual level of ketones in your blood or urine, but not high enough to cause acidosis. Ketones are a chemical your body produces when it burns stored fat. Some people choose a low-carb diet to help with weight loss. While there is some controversy over their safety, low-carb diets are generally fine. Talk to your doctor before beginning any extreme diet plan. DKA is the leading cause of death in people under 24 years old who have diabetes. The overall death rate for ketoacidosis is 2 to 5 percent. People under the age of 30 make up 36 percent of DKA cases. Twenty-seven percent of people with DKA are between the ages of 30 and 50, 23 percent are between the ages of 51 and 70, and 14 percent are over the age of 70. Ketosis may cause bad breath.

Diabetic Ketoacidosis

Diabetic Ketoacidosis

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

Diabetic Ketoacidosis

Print Overview Diabetic ketoacidosis is a serious complication of diabetes that occurs when your body produces high levels of blood acids called ketones. The condition develops when your body can't produce enough insulin. Insulin normally plays a key role in helping sugar (glucose) — a major source of energy for your muscles and other tissues — enter your cells. Without enough insulin, your body begins to break down fat as fuel. This process produces a buildup of acids in the bloodstream called ketones, eventually leading to diabetic ketoacidosis if untreated. If you have diabetes or you're at risk of diabetes, learn the warning signs of diabetic ketoacidosis — and know when to seek emergency care. Symptoms Diabetic ketoacidosis signs and symptoms often develop quickly, sometimes within 24 hours. For some, these signs and symptoms may be the first indication of having diabetes. You may notice: Excessive thirst Frequent urination Nausea and vomiting Abdominal pain Weakness or fatigue Shortness of breath Fruity-scented breath Confusion More-specific signs of diabetic ketoacidosis — which can be detected through home blood and urine testing kits — include: High blood sugar level (hyperglycemia) High ketone levels in your urine When to see a doctor If you feel ill or stressed or you've had a recent illness or injury, check your blood sugar level often. You might also try an over-the-counter urine ketones testing kit. Contact your doctor immediately if: You're vomiting and unable to tolerate food or liquid Your blood sugar level is higher than your target range and doesn't respond to home treatment Your urine ketone level is moderate or high Seek emergency care if: Your blood sugar level is consistently higher than 300 milligrams per deciliter (mg/dL), or 16.7 mill Continue reading >>

Diabetic Ketoacidosis Causes, Symptoms, Treatment, And Complications

Diabetic Ketoacidosis Causes, Symptoms, Treatment, And Complications

Diabetic ketoacidosis definition and facts Diabetic ketoacidosis is a life-threatening complication of type 1 diabetes (though rare, it can occur in people with type 2 diabetes) that occurs when the body produces high levels of ketones due to lack of insulin. Diabetic ketoacidosis occurs when the body cannot produce enough insulin. The signs and symptoms of diabetic ketoacidosis include Risk factors for diabetic ketoacidosis are type 1 diabetes, and missing insulin doses frequently, or being exposed to a stressor requiring higher insulin doses (infection, etc). Diabetic ketoacidosis is diagnosed by an elevated blood sugar (glucose) level, elevated blood ketones and acidity of the blood (acidosis). The treatment for diabetic ketoacidosis is insulin, fluids and electrolyte therapy. Diabetic ketoacidosis can be prevented by taking insulin as prescribed and monitoring glucose and ketone levels. The prognosis for a person with diabetic ketoacidosis depends on the severity of the disease and the other underlying medical conditions. Diabetic ketoacidosis (DKA) is a severe and life-threatening complication of diabetes. Diabetic ketoacidosis occurs when the cells in our body do not receive the sugar (glucose) they need for energy. This happens while there is plenty of glucose in the bloodstream, but not enough insulin to help convert glucose for use in the cells. The body recognizes this and starts breaking down muscle and fat for energy. This breakdown produces ketones (also called fatty acids), which cause an imbalance in our electrolyte system leading to the ketoacidosis (a metabolic acidosis). The sugar that cannot be used because of the lack of insulin stays in the bloodstream (rather than going into the cell and provide energy). The kidneys filter some of the glucose (suga Continue reading >>

Diabetic Ketoacidosis (dka)

Diabetic Ketoacidosis (dka)

Diabetic ketoacidosis is an acute metabolic complication of diabetes characterized by hyperglycemia, hyperketonemia, and metabolic acidosis. Hyperglycemia causes an osmotic diuresis with significant fluid and electrolyte loss. DKA occurs mostly in type 1 diabetes mellitus (DM). It causes nausea, vomiting, and abdominal pain and can progress to cerebral edema, coma, and death. DKA is diagnosed by detection of hyperketonemia and anion gap metabolic acidosis in the presence of hyperglycemia. Treatment involves volume expansion, insulin replacement, and prevention of hypokalemia. Diabetic ketoacidosis (DKA) is most common among patients with type 1 diabetes mellitus and develops when insulin levels are insufficient to meet the body’s basic metabolic requirements. DKA is the first manifestation of type 1 DM in a minority of patients. Insulin deficiency can be absolute (eg, during lapses in the administration of exogenous insulin) or relative (eg, when usual insulin doses do not meet metabolic needs during physiologic stress). Common physiologic stresses that can trigger DKA include Some drugs implicated in causing DKA include DKA is less common in type 2 diabetes mellitus, but it may occur in situations of unusual physiologic stress. Ketosis-prone type 2 diabetes is a variant of type 2 diabetes, which is sometimes seen in obese individuals, often of African (including African-American or Afro-Caribbean) origin. People with ketosis-prone diabetes (also referred to as Flatbush diabetes) can have significant impairment of beta cell function with hyperglycemia, and are therefore more likely to develop DKA in the setting of significant hyperglycemia. SGLT-2 inhibitors have been implicated in causing DKA in both type 1 and type 2 DM. Continue reading >>

Diabetic Ketoacidosis And Cerebral Edema.

Diabetic Ketoacidosis And Cerebral Edema.

Abstract Cerebral edema is the leading cause of death in children presenting in diabetic ketoacidosis and occurs in 0.2 to 1% of cases. The osmolar gradient caused by the high blood glucose results in water shift from the intracelluar fluid (ICF) to the extracellular fluid (ECF) space and contraction of cell volume. Correction with insulin and intravenous fluids can result in a rapid reduction in effective osmolarity, reversal of the fluid shift and the development of cerebral edema. The goals for treatment should be a combination of intravenous fluid and insulin that results in a gradual reduction of the effective osmolarity over a 36- to 48-hour period, thereby avoiding rapid expansion of the ICF compartment and brain swelling.

Diabetic Ketoacidosis In Pregnancy

Diabetic Ketoacidosis In Pregnancy

Diabetic ketoacidosis is a serious metabolic complication of diabetes with high mortality if undetected. Its occurrence in pregnancy compromises both the fetus and the mother profoundly. Although predictably more common in patients with type 1 diabetes, it has been recognised in those with type 2 diabetes as well as gestational diabetes, especially with the use of corticosteroids for fetal lung maturity and β2-agonists for tocolysis.1–3 Diabetic ketoacidosis usually occurs in the second and third trimesters because of increased insulin resistance, and is also seen in newly presenting type 1 diabetes patients. With increasing practice of antepartum diabetes screening and the availability of early and frequent prenatal care/surveillance, the incidence and outcomes of diabetic ketoacidosis in pregnancy have vastly improved. However, it still remains a major clinical problem in pregnancy since it tends to occur at lower blood glucose levels and more rapidly than in non-pregnant patients often causing delay in the diagnosis. The purpose of this article is to illustrate a typical patient who may present with diabetic ketoacidosis in pregnancy and review the literature on this relatively uncommon condition and provide an insight into the pathophysiology and management. MAGNITUDE OF THE PROBLEM In non-pregnant patients with type 1 diabetes, the incidence of diabetic ketoacidosis is about 1–5 episodes per 100 per year with mortality averaging 5%–10%.4 The incidence rates of diabetic ketoacidosis in pregnancy and the corresponding fetal mortality rates from different retrospective studies5–8 are summarised in the table 1. As is evident from the table, both the incidence and rates of fetal loss in pregnancies have fallen in recent times compared with those before. In 1963 Continue reading >>

What You Should Know About Diabetic Ketoacidosis

What You Should Know About Diabetic Ketoacidosis

Diabetic ketoacidosis (DKA) is a buildup of acids in your blood. It can happen when your blood sugar is too high for too long. It could be life-threatening, but it usually takes many hours to become that serious. You can treat it and prevent it, too. It usually happens because your body doesn't have enough insulin. Your cells can't use the sugar in your blood for energy, so they use fat for fuel instead. Burning fat makes acids called ketones and, if the process goes on for a while, they could build up in your blood. That excess can change the chemical balance of your blood and throw off your entire system. People with type 1 diabetes are at risk for ketoacidosis, since their bodies don't make any insulin. Your ketones can also go up when you miss a meal, you're sick or stressed, or you have an insulin reaction. DKA can happen to people with type 2 diabetes, but it's rare. If you have type 2, especially when you're older, you're more likely to have a condition with some similar symptoms called HHNS (hyperosmolar hyperglycemic nonketotic syndrome). It can lead to severe dehydration. Test your ketones when your blood sugar is over 240 mg/dL or you have symptoms of high blood sugar, such as dry mouth, feeling really thirsty, or peeing a lot. You can check your levels with a urine test strip. Some glucose meters measure ketones, too. Try to bring your blood sugar down, and check your ketones again in 30 minutes. Call your doctor or go to the emergency room right away if that doesn't work, if you have any of the symptoms below and your ketones aren't normal, or if you have more than one symptom. You've been throwing up for more than 2 hours. You feel queasy or your belly hurts. Your breath smells fruity. You're tired, confused, or woozy. You're having a hard time breathing.

What You Should Know About Diabetic Ketoacidosis

What You Should Know About Diabetic Ketoacidosis

Diabetic ketoacidosis (DKA) is a serious condition that can occur in diabetes. DKA happens when acidic substances, called ketones, build up in your body. Ketones are formed when your body burns fat for fuel instead of sugar, or glucose. That can happen if you don’t have enough insulin in your body to help you process sugars. Learn more: Ketosis vs. ketoacidosis: What you should know » Left untreated, ketones can build up to dangerous levels. DKA can occur in people who have type 1 or type 2 diabetes, but it’s rare in people with type 2 diabetes. DKA can also develop if you are at risk for diabetes, but have not received a formal diagnosis. It can be the first sign of type 1 diabetes. DKA is a medical emergency. Call your local emergency services immediately if you think you are experiencing DKA. Symptoms of DKA can appear quickly and may include: frequent urination extreme thirst high blood sugar levels high levels of ketones in the urine nausea or vomiting abdominal pain confusion fruity-smelling breath a flushed face fatigue rapid breathing dry mouth and skin It is important to make sure you consult with your doctor if you experience any of these symptoms. If left untreated, DKA can lead to a coma or death. All people who use insulin should discuss the risk of DKA with their healthcare team, to make sure a plan is in place. If you think you are experiencing DKA, seek immediate medical help. Learn more: Blood glucose management: Checking for ketones » If you have type 1 diabetes, you should maintain a supply of home urine ketone tests. You can use these to test your ketone levels. A high ketone test result is a symptom of DKA.

Diabetic Ketoacidosis

Diabetic Ketoacidosis

Practice Essentials Diabetic ketoacidosis (DKA) is an acute, major, life-threatening complication of diabetes that mainly occurs in patients with type 1 diabetes, but it is not uncommon in some patients with type 2 diabetes. This condition is a complex disordered metabolic state characterized by hyperglycemia, ketoacidosis, and ketonuria. Signs and symptoms The most common early symptoms of DKA are the insidious increase in polydipsia and polyuria. The following are other signs and symptoms of DKA: Nausea and vomiting; may be associated with diffuse abdominal pain, decreased appetite, and anorexia History of failure to comply with insulin therapy or missed insulin injections due to vomiting or psychological reasons or history of mechanical failure of insulin infusion pump Altered consciousness (eg, mild disorientation, confusion); frank coma is uncommon but may occur when the condition is neglected or with severe dehydration/acidosis Signs and symptoms of DKA associated with possible intercurrent infection are as follows: See Clinical Presentation for more detail. Diagnosis On examination, general findings of DKA may include the following: Characteristic acetone (ketotic) breath odor In addition, evaluate patients for signs of possible intercurrent illnesses such as MI, UTI, pneumonia, and perinephric abscess. Search for signs of infection is mandatory in all cases. Testing Initial and repeat laboratory studies for patients with DKA include the following: Serum electrolyte levels (eg, potassium, sodium, chloride, magnesium, calcium, phosphorus) Note that high serum glucose levels may lead to dilutional hyponatremia; high triglyceride levels may lead to factitious low glucose levels; and high levels of ketone bodies may lead to factitious elevation of creatinine levels.

Diabetic Ketoacidosis Symptoms

Diabetic Ketoacidosis Symptoms

What is diabetic ketoacidosis? Diabetic ketoacidosis, also referred to as simply ketoacidosis or DKA, is a serious and even life-threatening complication of type 1 diabetes. DKA is rare in people with type 2 diabetes. DKA is caused when insulin levels are low and not enough glucose can get into the body's cells. Without glucose for energy, the body starts to burn fat for energy. Ketones are products that are created when the body burns fat. The buildup of ketones causes the blood to become more acidic. The high levels of blood glucose in DKA cause the kidneys to excrete glucose and water, leading to dehydration and imbalances in body electrolyte levels. Diabetic ketoacidosis most commonly develops either due to an interruption in insulin treatment or a severe illness, including the flu. What are the symptoms and signs of diabetic ketoacidosis? The development of DKA is usually a slow process. However, if vomiting develops, the symptoms can progress more rapidly due to the more rapid loss of body fluid. Excessive urination, which occurs because the kidneys try to rid the body of excess glucose, and water is excreted along with the glucose High blood glucose (sugar) levels The presence of ketones in the urine Other signs and symptoms of ketoacidosis occur as the condition progresses: These include: Fatigue, which can be severe Flushing of the skin Fruity odor to the breath, caused by ketones Difficulty breathing Type 2 Diabetes Diagnosis, Treatment, Medication What should I do if I think I may have, or someone I know may diabetic ketoacidosis? You should test your urine for ketones if you suspect you have early symptoms or warning signs of ketoacidosis. Call your health-care professional if your urine shows high levels of ketones. High levels of ketones and high blood sug Continue reading >>

Diabetic Ketoacidosis

Diabetic Ketoacidosis

What Is It? Diabetic ketoacidosis is a potentially fatal complication of diabetes that occurs when you have much less insulin than your body needs. This problem causes the blood to become acidic and the body to become dangerously dehydrated. Diabetic ketoacidosis can occur when diabetes is not treated adequately, or it can occur during times of serious sickness. To understand this illness, you need to understand the way your body powers itself with sugar and other fuels. Foods we eat are broken down by the body, and much of what we eat becomes glucose (a type of sugar), which enters the bloodstream. Insulin helps glucose to pass from the bloodstream into body cells, where it is used for energy. Insulin normally is made by the pancreas, but people with type 1 diabetes (insulin-dependent diabetes) don't produce enough insulin and must inject it daily.

An Unusual Cause For Ketoacidosis

An Unusual Cause For Ketoacidosis

Abstract Introduction In our continuing series on the application of principles of integrative physiology at the bedside, once again the central figure is an imaginary consultant, the renal and metabolic physiologist, Professor McCance, who deals with data from a real case. On this occasion his colleague Sir Hans Krebs, an expert in the field of glucose and energy metabolism, assists him in the analysis. Their emphasis is on concepts that depend on an understanding of physiology that crosses subspecialty boundaries. To avoid overwhelming the reader with details, key facts are provided, but only when necessary. The overall objective of this teaching exercise is to demonstrate how application of simple principles of integrative physiology at the bedside can be extremely helpful for clinical decision-making (Table 1). Principle Comment 1. A high H+ concentration per se is seldom life-threatening The threat to survival is usually due to the cause for the acidosis rather than the pH per se 2. Finding a new anion means a new acid was added Look in plasma (anion gap) and urine (net charge) to identify the new anions 3. Identify the acid by thinking of the properties of the anion Rate of production, rapidity of clearance from plasma, and unique toxic effects may all provide clues 4. Metabolic acidosis develops when the kidney fails to add new HCO3 to the body The kidney generates HCO3− by excreting NH4+, (usually with Cl−), in the urine 5. Ketoacids are brain fuels, produced when there is a prolonged lack of insulin The usual causes are diabetic ketoacidosis, alcoholic ketoacidosis, starvation or hypoglycemia-induced ketoacidosis, or that associated with salicylate overdose 6. Ketoacids are produced in the liver from acetyl-CoA, usually derived from fatty acids A low net in Continue reading >>
