Respiratory Failure In Diabetic Ketoacidosis
Go to: INTRODUCTION Ketoacidosis in subjects with type 1, or less frequently, type 2 diabetes mellitus remains a potentially life-threatening diabetic manifestation. The subject has justifiably attracted attention in the literature. Sequential reviews[1-9] have documented important changes in the clinical concepts that are related to diabetic ketoacidosis (DKA) and its management. A large number of case series of DKA have addressed various aspects of its clinical presentation and management. For this review, we selected representative studies focused on management, outcome, age differences, gender differences, associated morbid conditions, ethnicity and prominent clinical and laboratory features[10-35]. In recognition of the complexity of treatment, the recommendation to provide this care in intensive care units was made more than 50 years ago. Severe DKA is treated in intensive care units today. Evidence-based guidelines for the diagnosis and management of DKA have been published and frequently revised in North America[37,38] and Europe. Losses of fluids and electrolytes, which are important causes of morbidity and mortality in DKA, vary greatly between patients. Quantitative methods estimating individual losses and guiding their replacement have also been reported[40,41]. The outcomes of DKA have improved with new methods of insulin administration and adherence to guidelines[43-46]. The aim of treatment is to minimize mortality and prevent sequelae. One study documented that the target of zero mortality is feasible. However, mortality from DKA, although reduced progressively in the early decades after the employment of insulin treatment, remains high. Up to fifty plus years ago, mortality from DKA was between 3% and 10%[1,16]. A recent review re Continue reading >>
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 >>
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.

What The Heck Is Ketoacidosis?
By Gary Scheiner MS, CDE 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 can kill you. The primary cause of DKA is a lack of working insulin in the body. Let me explain. Normal Fuel Metabolism 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. As you can tell, 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 (see figure below). Abnormal Fuel Metabolism What would happen if you had no insulin? I’m not talking about a minor under-dosage; I’m talking about having none whatsoever. A number of things would start to go wrong. 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, leads to th Continue reading >>
Can You Die Of Starvation With Large Amounts Of Adipose Tissue?
This paper gives an numbers based answer, and by extrapolation, it would seem the more adipose tissue you have, the longer you can without food: “Anaverage human of 165 pounds has roughly 33 pounds of fat…and 26 pounds of protein suspended in 132 pounds of lean body mass, mostly muscle. Practicallyall of the body fat is expendable without serious adverse effects. In contrast, only one-half of the body’s protein can be mobilized and used as fuel before death occurs. Theconversion of 6 kg of protein to glucose results in the formation of only 3.4 kg of glucose. If the brain oxidizes 100–145 g of glucose daily, the average human could starve for only 23–34 days. The fact that the brain can derive two-thirds of its energy from ketone bodies, synthesized mostly from fat, allows humans to survive total starvation for 60–90 days.”1 1. Owen OE.

Is Type 1 Diabetes More Dangerous Than Type 2?
Type 1 diabetes results from a rheumatoid-like autoimmune reaction in which one’s own body attacks and destroys the beta cells of the pancreas. These are the cells that normally produce insulin. Type 1 is a disease in which the patient in a relatively short time has no insulin production. All patients with type 1 diabetes can also develop a serious metabolic disorder called ketoacidosis when their blood sugars are high and there is not enough insulin in their body. Ketoacidosis can be fatal unless treated as an emergency with hydration and insulin. Type 2 diabetes rates are growing dramatically in the United States and Western Europe. Type 2 is the result of the muscles and other tissues of the body developing a resistance to insulin produced by the beta cells of the pancreas. The pancreas first tries to overcome this resistance to insulin by making more insulin. The blood sugar goes up as a patient’s body is no longer able to make enough insulin. Most patients with type 2 diabetes mellitus are overweight or obese. For most, but not all, maintenance of a normal weight and a good diet will prevent development of type 2 diabetes. Most type 2 diabetes is diagnosed after age 40. For this reason, many have referred to type 2 as adult-onset diabetes mellitus. This latter name has lost favor as the obesity epidemic has caused a number of people to be diagnosed with type 2 as early as 10 or 11. Type 2 can often be treated with diet modification and can improve significantly with weight loss and exercise. Some patients will be effectively treated with medications such as metformin that increase peripheral sensitivity of organs to insulin. Still more severe disease will require oral medications that encourage the pancreas to make more insulin such as glyburide or glipizide So Continue reading >>

Ketoacidosis is a metabolic state associated with high concentrations of ketone bodies, formed by the breakdown of fatty acids and the deamination of amino acids. The two common ketones produced in humans are acetoacetic acid and β-hydroxybutyrate. Ketoacidosis is a pathological metabolic state marked by extreme and uncontrolled ketosis. In ketoacidosis, the body fails to adequately regulate ketone production causing such a severe accumulation of keto acids that the pH of the blood is substantially decreased. In extreme cases ketoacidosis can be fatal. Ketoacidosis is most common in untreated type 1 diabetes mellitus, when the liver breaks down fat and proteins in response to a perceived need for respiratory substrate. Prolonged alcoholism may lead to alcoholic ketoacidosis. Ketoacidosis can be smelled on a person's breath. This is due to acetone, a direct by-product of the spontaneous decomposition of acetoacetic acid. It is often described as smelling like fruit or nail polish remover. Ketosis may also give off an odor, but the odor is usually more subtle due to lower concentrations of acetone. Treatment consists most simply of correcting blood sugar and insulin levels, which will halt ketone production. If the severity of the case warrants more aggressive measures, intravenous sodium bicarbonate infusion can be given to raise blood pH back to an acceptable range. However, serious caution must be exercised with IV sodium bicarbonate to avoid the risk of equally life-threatening hypernatremia. Cause Three common causes of ketoacidosis are alcohol, starvation, and diabetes, resulting in alcoholic ketoacidosis, starvation ketoacidosis, and diabetic ketoacidosis respectively. In diabetic ketoacidosis, a high concentration of ketone bodies is usually accomp Continue reading >>
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.

Diabetic ketoacidosis (DKA) is a serious complications of untreated diabetes. In this complication, severely insufficient insulin levels in the body results into high blood sugar that leads to the production and buildup of ketones in the blood. These ketones are slightly acidic, and large amounts of them can lead to ketoacidosis. If remained untreated, the condition leads to diabetic coma and may be fatal. Diabetic ketoacidosis (DKA) gets triggered by a stressful event on the body, such as an illness or severe lack of insulin. DKA is more common in people with type 1 diabetes. In some cases, identification of DKA is the first indication that a person has diabetes. Early Sluggish and extreme tiredness Fruity smell to breath (like acetone) Extreme thirst, despite large fluid intake Constant urination/bedwetting Extreme weight loss Presence of Oral Thrush or yeast infections that fail to go away Muscle wasting Agitation / Irritation / Aggression / Confusion Late At this stage, Diabetic ketoacidosis reaches a life-threatening level: Vomiting. Although this can be a sign of hyperglycemia and isn't always a late-stage sign, it can occur with or without ketoacidosis. Confusion Abdominal pain Loss of appetite Flu-like symptoms Unconsciousness (diabetic coma) Being lethargic and apathetic Extreme weakness Kussmaul breathing (air hunger). In this condition, patients breathe more deeply and/or more rapidly The major risk factors accelerating on set of diabetic ketoacidosis include the following: Diabetes mellitus: Type 1 diabetics are at a higher risk of DKA, because they must rely on outside insulin sources for survival. DKA can occur in patients with type 2, particularly in obese children. Age: DKA may occur at any age, but younger people below 19 years of age are more susceptib Continue reading >>
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. Ket Continue reading >>
Symptoms Of Diabetic Ketoacidosis: What You Need To Know
Diabetes can be hard to manage, but not properly controlling the disease can have dangerous and potentially deadly consequences. Ketoacidosis is one of them. This condition happens in people who don’t have enough insulin in their body, perhaps because they have not taken some of their insulin shots. The U.S. National Library of Medicine explains that when insulin is lacking, and the body cannot use ingested sugar as a fuel source, it starts to break down fat, which releases acids called ketones into the bloodstream. In large numbers, those ketones are poisonous and can cause deep, rapid breathing, dry skin and mouth, frequent thirst, a flushed face, headache, nausea, stomach pain, muscle stiffness, muscle aches, frequent urination, difficulty concentrating and fruity-smelling breath. If left untreated, the condition can be fatal, in part because it can eventually cause fluid to build up in the brain and for the heart and kidneys to stop working. There are ways to tell whether you have the condition or are approaching it, the Mayo Clinic says. A routine blood sugar test like the kind diabetics take all the time will show high blood sugar, and there are tests to measure the ketone levels in urine. The American Diabetes Association says that experts usually recommend using a urine test strip to check for ketones when blood glucose levels reach higher than 240 milligrams per deciliter. And when sick with a cold or flu, a person should “check for ketones every four to six hours” to be safe. That’s because infections or other illnesses can increase hormones like adrenaline and cortisol in the body, which then counter the work of insulin — “pneumonia and urinary tract infections are common culprits,” the Mayo Clinic warns. In addition to missed insulin shots 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 >>
What Is The Longest A Diabetic Can Go Without An Injection?
Type one diabetes at the most two to three days, by that time they would be severely ketotic, risking a sometimes fatal diabetes hyperglycemic ketoacidotic coma. For type 2 diabetes mostly that can be for months, even years, like we see in those war torn areas. My erstwhile partner, when I met him already a senior physician, told me that the experience during WW II in The Netherlands, those mostly type 2 diabetics who couldn’t get insulin didn’t die from not having insulin (which at the end was air-dropped by the British into German occupied territories), in fact did quite well with their blood sugars, unfortunately for a very sad reason: the Dutch famine of 1944–45 - Wikipedia costing about 18,000 people their lives. Of course not having their diabetes well controlled would cause them to develop a lot more complications so would shorten their lifespan appreciably. Continue reading >>

Can Type 2 Diabetes Lead To Death?
The answer is a resounding YES. You just have to look at this recently published study this year by the University of Pennsylvania which shows that diabetes now makes up 12% of all deaths in the US, a higher number than previously thought. Death from type 2 diabetes could come in many ways : Acute complications of diabetes. For example, severe hypoglycemia (low blood sugar) especially for patients on insulin injections. Or on the end of the spectrum, poor blood glucose control can lead to diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar nonketotic coma (HHNK), which have significant mortality rates. Long-term complications of diabetes. This comprises the bulk of deaths from diabetes, and include heart disease, kidney failure, stroke, infections, limb amputations. But here’s the good news: the large majority of people with diabetes can lead a good, healthy and long life!

Diabetic Ketoacidosis Causes
Diabetic ketoacidosis (DKA) is a dangerous complication of diabetes mellitus brought about by a lack of insulin in the body causing an inadequate uptake of glucose from the blood. It is characterized by a severe rise in blood sugar or hyperglycemia along with dehydration that may lead to shock and even loss of consciousness. Insulin is an important hormone that helps the body uptake and utilize glucose present in blood, therefore reducing the blood sugar level. If there is a lack of insulin, the blood sugar is not used and instead body fats are broken down to provide an alternative energy source. This breakdown of fat however, causes the release of acidic by-products called ketones that build up in the blood and urine. High glucose levels cause increased amounts of glucose to move into the urine, a process termed osmotic diuresis. During osmotic diuresis, water and solutes such as potassium and sodium also move into the urine. This leads to frequent excretion of large volumes of urine or polyuria, dehydration and compensatory thirst or polydypsia. Who is affected? DKA is more common among people with type 1 diabetes or those with type 2 diabetes who take insulin to regulate their blood sugar levels. Nearly a quarter of all type 1 diabetics are admitted to hospital with DKA at some point in their lives. Young children with type 1 diabetes are at particular risk of developing the condition. Causes Common causes or triggers of DKA typically include situations that raise the body's requirement for insulin. Examples include: Acute infection During infection, the body has an increased need for glucose that may not be met by an adequate amount of insulin for stimulating the uptake of glucose from the blood. Examples of infections that can cause this problem include the flu, ur Continue reading >>
