What Is Diabetic Ketoacidosis?

Diabetic ketoacidosis is a buildup of acids in the blood. It is a life-threatening complication of diabetes resulting from not having enough insulin. It may happen with type 1 diabetes. (It rarely happens with type 2 diabetes.) It’s an emergency that must be treated right away. If ketoacidosis is not treated right away, it can cause coma or death. What is the cause? Diabetic ketoacidosis happens when the body does not have enough insulin. Without insulin, sugars in the blood cannot move out of the blood and into the body’s cells, so the cells burn fats instead of sugar for energy. The burning of fats makes byproducts called ketones. The ketones build up to poisonous and dangerous levels in the blood. Usually the blood sugar is also very high. Ketoacidosis can happen if you skip doses of insulin. Or it may happen if there is a change in your life, such as: Infection Injury Heart attack Surgery Pregnancy Other types of physical or emotional stress If you are using an insulin pump, it may happen if you stop getting insulin because there is a kink in the tube or the tube comes out. Sometimes you may not know you have diabetes until ketoacidosis occurs. When the pancreas stops making insulin, it happens over a short period of time. In just a few days your blood sugar can get very high and ketones can build up to a high level very fast. It may happen so fast that ketoacidosis symptoms are the first symptoms of diabetes that you have. What are the symptoms? Symptoms of ketoacidosis may include: Shortness of breath Fruity smelling breath Very dry mouth Nausea and vomiting Symptoms of high blood sugar may include: Blurry vision Dry mouth Feeling very thirsty and drinking a lot Urinating a lot Tiredness Several hours to a couple of days after symptoms start, ketoacidosis may Continue reading >>

Diagnosis And Treatment Of Diabetic Ketoacidosis And The Hyperglycemic Hyperosmolar State

Diagnosis And Treatment Of Diabetic Ketoacidosis And The Hyperglycemic Hyperosmolar State

Go to: Pathogenesis In both DKA and HHS, the underlying metabolic abnormality results from the combination of absolute or relative insulin deficiency and increased amounts of counterregulatory hormones. Glucose and lipid metabolism When insulin is deficient, the elevated levels of glucagon, catecholamines and cortisol will stimulate hepatic glucose production through increased glycogenolysis and enhanced gluconeogenesis4 (Fig. 1). Hypercortisolemia will result in increased proteolysis, thus providing amino acid precursors for gluconeogenesis. Low insulin and high catecholamine concentrations will reduce glucose uptake by peripheral tissues. The combination of elevated hepatic glucose production and decreased peripheral glucose use is the main pathogenic disturbance responsible for hyperglycemia in DKA and HHS. The hyperglycemia will lead to glycosuria, osmotic diuresis and dehydration. This will be associated with decreased kidney perfusion, particularly in HHS, that will result in decreased glucose clearance by the kidney and thus further exacerbation of the hyperglycemia. In DKA, the low insulin levels combined with increased levels of catecholamines, cortisol and growth hormone will activate hormone-sensitive lipase, which will cause the breakdown of triglycerides and release of free fatty acids. The free fatty acids are taken up by the liver and converted to ketone bodies that are released into the circulation. The process of ketogenesis is stimulated by the increase in glucagon levels.5 This hormone will activate carnitine palmitoyltransferase I, an enzyme that allows free fatty acids in the form of coenzyme A to cross mitochondrial membranes after their esterification into carnitine. On the other side, esterification is reversed by carnitine palmitoyltransferase I Continue reading >>

What Is Diabetic Ketoacidosis?

Diabetic ketoacidosis, or DKA, is a serious health problem that can happen to a person with diabetes. It happens when chemicals called ketones build up in the blood. Normally, the cells of your body take in and use glucose as a source of energy. Glucose moves through the body in the bloodstream. Insulin is a hormone that helps your cells take in the glucose from the blood. If you have diabetes, your cells can’t take in and use this glucose in a normal way. This may be because your body doesn’t make enough insulin. Or it may be because your cells don’t respond to it normally. As a result, glucose builds up in your bloodstream and doesn’t reach your cells. Without glucose to use, the cells in your body burn fat instead of glucose for energy. When cells burn fat, they make ketones. High levels of ketones can poison the body. High levels of glucose can also build up in your blood and cause other symptoms. Ketoacidosis also changes the amount of other substances in your blood. These include electrolytes, such as sodium, potassium, and bicarbonate. This can lead to other problems. Ketoacidosis happens most often in a person with type 1 diabetes. This is a condition where the body does not make enough insulin. In rare cases, ketoacidosis can happen in a person with type 2 diabetes. It can happen when they are under stress, like when they are sick, or when they have taken certain medicines that change how their bodies handle glucose. Diabetic ketoacidosis is pretty common. It is more common in younger people. Women have it more often than men do. What causes diabetic ketoacidosis? High levels of ketones and glucose in your blood can cause ketoacidosis. This might happen if you: Don’t know you have diabetes, and your body is breaking down too much fat Know you have dia Continue reading >>

The Scary Experience Of Diabetic Ketoacidosis

The Scary Experience Of Diabetic Ketoacidosis

Today, we’re excited to share with you another guest blog from Katie Janowiak, who works for the Medtronic Foundation, our company’s philanthropic arm. When she first told me her story about food poisoning and Diabetic Ketoacidosis (DKA), I knew others could benefit from hearing it as well. Thanks Katie for your openness and allowing us to share your scary story so that the LOOP community can learn from it. Throughout this past year, I’ve had the honor of sharing with you, the amazing LOOP community, my personal journey and the often humorous sequence of events that is my life with T1. Humor is, after all, the best (and cheapest) therapy. Allow me to pause today to share with you the down and dirty of what it feels like to have something that is not the slightest bit humorous: diabetic ketoacidosis.You are hot. You are freezing. You are confused. You are blacked out but coherent. You go to talk but words fail you. Time flies and goes in slow motion simultaneously. You will likely smell and look like death. In my instance, this was brought on by the combination of excessive vomiting and dehydration caused by food poisoning and the diabetic ketoacidosis that followed after my body had gone through so much. In hindsight, I was lucky, my husband knew that I had food poisoning because I began vomiting after our meal. But I had never prepped him on diabetic ketoacidosis and the symptoms (because DKA was for those other diabetics.) Upon finding me in our living room with a bowl of blood and bile by my side (no, I am not exaggerating), he got me into the car and took me to emergency care. It was 5:30 p.m. – and I thought it was 11:00 a.m. The series of events that led up to my stay in the ICU began innocently enough. It was a warm summer night and my husband and I walke Continue reading >>

Diabetic Ketoacidosis

Diabetic Ketoacidosis

Diabetic acidosis is a life-threatening condition that can occur in people with type 1 diabetes. Less commonly, it can also occur with type 2 diabetes. Term watch Ketones: breakdown products from the use of fat stores for energy. Ketoacidosis: another name for diabetic acidosis. It happens when a lack of insulin leads to: Diabetic acidosis requires immediate hospitalisation for urgent treatment with fluids and intravenous insulin. It can usually be avoided through proper treatment of Type 1 diabetes. However, ketoacidosis can also occur with well-controlled diabetes if you get a severe infection or other serious illness, such as a heart attack or stroke, which can cause vomiting and resistance to the normal dose of injected insulin. What causes diabetic acidosis? The condition is caused by a lack of insulin, most commonly when doses are missed. While insulin's main function is to lower the blood sugar level, it also reduces the burning of body fat. If the insulin level drops significantly, the body will start burning fat uncontrollably while blood sugar levels rise. Glucose will then begin to show up in your urine, along with ketone bodies from fat breakdown that turn the body acidic. The body attempts to reduce the level of acid by increasing the rate and depth of breathing. This blows off carbon dioxide in the breath, which tends to correct the acidosis temporarily (known as acidotic breathing). At the same time, the high secretion of glucose into the urine causes large quantities of water and salts to be lost, putting the body at serious risk of dehydration. Eventually, over-breathing becomes inadequate to control the acidosis. What are the symptoms? Since diabetic acidosis is most often linked with high blood sugar levels, symptoms are the same as those for diabetes 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 >>

Acute Complications Of Diabetes - Diabetic Ketoacidosis

Acute Complications Of Diabetes - Diabetic Ketoacidosis

- [Voiceover] Oftentimes we think of diabetes mellitus as a chronic disease that causes serious complications over a long period of time if it's not treated properly. However, the acute complications of diabetes mellitus are often the most serious, and can be potentially even life threatening. Let's discuss one of the acute complications of diabetes, known as diabetic ketoacidosis, or DKA for short, which can occur in individuals with type 1 diabetes. Now recall that type 1 diabetes is an autoimmune disorder. And as such, there's an autoimmune destruction of the beta cells in the pancreas, which prevents the pancreas from producing and secreting insulin. Therefore, there is an absolute insulin deficiency in type 1 diabetes. But what exactly does this mean for the body? To get a better understanding, let's think about insulin requirements as a balancing act with energy needs. Now the goal here is to keep the balance in balance. As the energy requirements of the body go up, insulin is needed to take the glucose out of the blood and store it throughout the body. Normally in individuals without type 1 diabetes, the pancreas is able to produce enough insulin to keep up with any amount of energy requirement. But how does this change is someone has type 1 diabetes? Well since their pancreas cannot produces as much insulin, they have an absolute insulin deficiency. Now for day-to-day activities, this may not actually cause any problems, because the small amount of insulin that is produced is able to compensate and keep the balance in balance. However, over time, as type 1 diabetes worsens, and less insulin is able to be produced, then the balance becomes slightly unequal. And this results in the sub-acute or mild symptoms of type 1 diabetes such as fatigue, because the body isn Continue reading >>

Diabetic Ketoacidosis - Symptoms

Diabetic Ketoacidosis - Symptoms

A A A Diabetic Ketoacidosis Diabetic ketoacidosis (DKA) results from dehydration during a state of relative insulin deficiency, associated with high blood levels of sugar level and organic acids called ketones. Diabetic ketoacidosis is associated with significant disturbances of the body's chemistry, which resolve with proper therapy. Diabetic ketoacidosis usually occurs in people with type 1 (juvenile) diabetes mellitus (T1DM), but diabetic ketoacidosis can develop in any person with diabetes. Since type 1 diabetes typically starts before age 25 years, diabetic ketoacidosis is most common in this age group, but it may occur at any age. Males and females are equally affected. Diabetic ketoacidosis occurs when a person with diabetes becomes dehydrated. As the body produces a stress response, hormones (unopposed by insulin due to the insulin deficiency) begin to break down muscle, fat, and liver cells into glucose (sugar) and fatty acids for use as fuel. These hormones include glucagon, growth hormone, and adrenaline. These fatty acids are converted to ketones by a process called oxidation. The body consumes its own muscle, fat, and liver cells for fuel. In diabetic ketoacidosis, the body shifts from its normal fed metabolism (using carbohydrates for fuel) to a fasting state (using fat for fuel). The resulting increase in blood sugar occurs, because insulin is unavailable to transport sugar into cells for future use. As blood sugar levels rise, the kidneys cannot retain the extra sugar, which is dumped into the urine, thereby increasing urination and causing dehydration. Commonly, about 10% of total body fluids are lost as the patient slips into diabetic ketoacidosis. Significant loss of potassium and other salts in the excessive urination is also common. The most common Continue reading >>

Diabetic Ketoacidosis

Diabetic Ketoacidosis

Introduction Diabetic ketoacidosis (DKA) is a dangerous complication of diabetes caused by a lack of insulin in the body. Diabetic ketoacidosis occurs when the body is unable to use blood sugar (glucose) because there isn't enough insulin. Instead, it breaks down fat as an alternative source of fuel. This causes a build-up of a by-product called ketones. Most cases of diabetic ketoacidosis occur in people with type 1 diabetes, although it can also be a complication of type 2 diabetes. Symptoms of diabetic ketoacidosis include: passing large amounts of urine feeling very thirsty vomiting abdominal pain Seek immediate medical assistance if you have any of these symptoms and your blood sugar levels are high. Read more about the symptoms of diabetic ketoacidosis. Who is affected by diabetic ketoacidosis? Diabetic ketoacidosis is a relatively common complication in people with diabetes, particularly children and younger adults who have type 1 diabetes. Younger children under four years of age are thought to be most at risk. In about 1 in 4 cases, diabetic ketoacidosis develops in people who were previously unaware they had type 1 diabetes. Diabetic ketoacidosis accounts for around half of all diabetes-related hospital admissions in people with type 1 diabetes. Diabetic ketoacidosis triggers These include: infections and other illnesses not keeping up with recommended insulin injections Read more about potential causes of diabetic ketoacidosis. Diagnosing diabetic ketoacidosis This is a relatively straightforward process. Blood tests can be used to check your glucose levels and any chemical imbalances, such as low levels of potassium. Urine tests can be used to estimate the number of ketones in your body. Blood and urine tests can also be used to check for an underlying infec 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

Diabetic Ketoacidosis

Diabetic ketoacidosis (DKA) happens when your blood sugar is high and your insulin level is low. This imbalance in the body causes a build-up of ketones. Ketones are toxic. If DKA isn’t treated, it can lead to diabetic coma and even death. DKA mainly affects people who have type 1 diabetes. But it can also happen with other types of diabetes, including type 2 diabetes and gestational diabetes (during pregnancy). DKA is a very serious condition. If you have diabetes and think you may have DKA, contact your doctor or get to a hospital right away. The first symptoms to appear are usually: frequent urination. The next stage of DKA symptoms include: vomiting (usually more than once) confusion or trouble concentrating a fruity odor on the breath. The main cause of DKA is not enough insulin. A lack of insulin means sugar can’t get into your cells. Your cells need sugar for energy. This causes your body’s glucose levels to rise. To get energy, the body starts to burn fat. This process causes ketones to build up. Ketones can poison the body. High blood glucose levels can also cause you to urinate often. This leads to a lack of fluids in the body (dehydration). DKA can be caused by missing an insulin dose, eating poorly, or feeling stressed. An infection or other illness (such as pneumonia or a urinary tract infection) can also lead to DKA. If you have signs of infection (fever, cough, or sore throat), contact your doctor. You will want to make sure you are getting the right treatment. For some people, DKA may be the first sign that they have diabetes. When you are sick, you need to watch your blood sugar level very closely so that it doesn’t get too high or too low. Ask your doctor what your critical blood sugar level is. Most patients should watch their glucose levels c Continue reading >>

Diabetic Ketoacidosis

Diabetic Ketoacidosis

The Facts Diabetic ketoacidosis (DKA) is a condition that may occur in people who have diabetes, most often in those who have type 1 (insulin-dependent) diabetes. It involves the buildup of toxic substances called ketones that make the blood too acidic. High ketone levels can be readily managed, but if they aren't detected and treated in time, a person can eventually slip into a fatal coma. DKA can occur in people who are newly diagnosed with type 1 diabetes and have had ketones building up in their blood prior to the start of treatment. It can also occur in people already diagnosed with type 1 diabetes that have missed an insulin dose, have an infection, or have suffered a traumatic event or injury. Although much less common, DKA can occasionally occur in people with type 2 diabetes under extreme physiologic stress. Causes With type 1 diabetes, the pancreas is unable to make the hormone insulin, which the body's cells need in order to take in glucose from the blood. In the case of type 2 diabetes, the pancreas is unable to make sufficient amounts of insulin in order to take in glucose from the blood. Glucose, a simple sugar we get from the foods we eat, is necessary for making the energy our cells need to function. People with diabetes can't get glucose into their cells, so their bodies look for alternative energy sources. Meanwhile, glucose builds up in the bloodstream, and by the time DKA occurs, blood glucose levels are often greater than 22 mmol/L (400 mg/dL) while insulin levels are very low. Since glucose isn't available for cells to use, fat from fat cells is broken down for energy instead, releasing ketones. Ketones accumulate in the blood, causing it to become more acidic. As a result, many of the enzymes that control the body's metabolic processes aren't able Continue reading >>

How Dka Happens And What To Do About It

How Dka Happens And What To Do About It

Certified Diabetes Educator Gary Scheiner offers an overview of diabetic ketoacidosis. (excerpted from Think Like A Pancreas: A Practical Guide to Managing Diabetes With Insulin by Gary Scheiner MS, CDE, DaCapo Press, 2011) Diabetic Ketoacidosis (DKA) is a condition in which the blood becomes highly acidic as a result of dehydration and excessive ketone (acid) production. When bodily fluids become acidic, some of the body’s systems stop functioning properly. It is a serious condition that will make you violently ill and it can kill you. The primary cause of DKA is a lack of working insulin in the body. Most of the body’s cells burn primarily sugar (glucose) for energy. Many cells also burn fat, but in much smaller amounts. Glucose happens to be a very “clean” form of energy—there are virtually no waste products left over when you burn it up. Fat, on the other hand, is a “dirty” source of energy. When fat is burned, there are waste products produced. These waste products are called “ketones.” Ketones are acid molecules that can pollute the bloodstream and affect the body’s delicate pH balance if produced in large quantities. Luckily, we don’t tend to burn huge amounts of fat at one time, and the ketones that are produced can be broken down during the process of glucose metabolism. Glucose and ketones can “jump into the fire” together. It is important to have an ample supply of glucose in the body’s cells. That requires two things: sugar (glucose) in the bloodstream, and insulin to shuttle the sugar into the cells. A number of things would start to go wrong if you have no insulin in the bloodstream: Without insulin, glucose cannot get into the body’s cells. As a result, the cells begin burning large amounts of fat for energy. This, of course, Continue reading >>

Diabetic Ketoacidosis

Diabetic Ketoacidosis

Diabetic ketoacidosis (DKA) is a potentially life-threatening complication of diabetes mellitus.[1] Signs and symptoms may include vomiting, abdominal pain, deep gasping breathing, increased urination, weakness, confusion, and occasionally loss of consciousness.[1] A person's breath may develop a specific smell.[1] Onset of symptoms is usually rapid.[1] In some cases people may not realize they previously had diabetes.[1] DKA happens most often in those with type 1 diabetes, but can also occur in those with other types of diabetes under certain circumstances.[1] Triggers may include infection, not taking insulin correctly, stroke, and certain medications such as steroids.[1] DKA results from a shortage of insulin; in response the body switches to burning fatty acids which produces acidic ketone bodies.[3] DKA is typically diagnosed when testing finds high blood sugar, low blood pH, and ketoacids in either the blood or urine.[1] The primary treatment of DKA is with intravenous fluids and insulin.[1] Depending on the severity, insulin may be given intravenously or by injection under the skin.[3] Usually potassium is also needed to prevent the development of low blood potassium.[1] Throughout treatment blood sugar and potassium levels should be regularly checked.[1] Antibiotics may be required in those with an underlying infection.[6] In those with severely low blood pH, sodium bicarbonate may be given; however, its use is of unclear benefit and typically not recommended.[1][6] Rates of DKA vary around the world.[5] In the United Kingdom, about 4% of people with type 1 diabetes develop DKA each year, while in Malaysia the condition affects about 25% a year.[1][5] DKA was first described in 1886 and, until the introduction of insulin therapy in the 1920s, it was almost univ Continue reading >>

Ketoacidosis: A Diabetes Complication

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 >>
