What Does Ketoacidosis Do

Diabetic Ketoacidosis And Hyperglycaemic Hyperosmolar State

Diabetic Ketoacidosis And Hyperglycaemic Hyperosmolar State

The hallmark of diabetes is a raised plasma glucose resulting from an absolute or relative lack of insulin action. Untreated, this can lead to two distinct yet overlapping life-threatening emergencies. Near-complete lack of insulin will result in diabetic ketoacidosis, which is therefore more characteristic of type 1 diabetes, whereas partial insulin deficiency will suppress hepatic ketogenesis but not hepatic glucose output, resulting in hyperglycaemia and dehydration, and culminating in the hyperglycaemic hyperosmolar state. Hyperglycaemia is characteristic of diabetic ketoacidosis, particularly in the previously undiagnosed, but it is the acidosis and the associated electrolyte disorders that make this a life-threatening condition. Hyperglycaemia is the dominant feature of the hyperglycaemic hyperosmolar state, causing severe polyuria and fluid loss and leading to cellular dehydration. Progression from uncontrolled diabetes to a metabolic emergency may result from unrecognised diabetes, sometimes aggravated by glucose containing drinks, or metabolic stress due to infection or intercurrent illness and associated with increased levels of counter-regulatory hormones. Since diabetic ketoacidosis and the hyperglycaemic hyperosmolar state have a similar underlying pathophysiology the principles of treatment are similar (but not identical), and the conditions may be considered two extremes of a spectrum of disease, with individual patients often showing aspects of both. Pathogenesis of DKA and HHS Insulin is a powerful anabolic hormone which helps nutrients to enter the cells, where these nutrients can be used either as fuel or as building blocks for cell growth and expansion. The complementary action of insulin is to antagonise the breakdown of fuel stores. Thus, the relea 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.

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 (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

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.

Why Is Diabetic Ketoacidosis So Dangerous?

Why Is Diabetic Ketoacidosis So Dangerous?

The main thing, which Carol Linn Miller so very correctly points out, is that diabetic ketoacidosis can be fatal. But having been through it, what makes the condition so dangerous is you don't necessarily feel like you need to get it treated. You go off into a kind of la-la land, and don't take necessary action. If you wait too long, you may die. I didn't go to an ER until I suddenly went blind, and it turned out I was near death. I knew something was wrong, but the part of my brain that tells you "Danger! Danger!" wasn't working. Continue reading >>

Ketoacidosis

Ketoacidosis

GENERAL ketoacidosis is a high anion gap metabolic acidosis due to an excessive blood concentration of ketone bodies (keto-anions). ketone bodies (acetoacetate, beta-hydroxybutyrate, acetone) are released into the blood from the liver when hepatic lipid metabolism has changed to a state of increased ketogenesis. a relative or absolute insulin deficiency is present in all cases. CAUSES The three major types of ketosis are: (i) Starvation ketosis (ii) Alcoholic ketoacidosis (iii) Diabetic ketoacidosis STARVATION KETOSIS when hepatic glycogen stores are exhausted (eg after 12-24 hours of total fasting), the liver produces ketones to provide an energy substrate for peripheral tissues. ketoacidosis can appear after an overnight fast but it typically requires 3 to 14 days of starvation to reach maximal severity. typical keto-anion levels are only 1 to 2 mmol/l and this will usually not alter the anion gap. the acidosis even with quite prolonged fasting is only ever of mild to moderate severity with keto-anion levels up to a maximum of 3 to 5 mmol/l and plasma pH down to 7.3. ketone bodies also stimulate some insulin release from the islets. patients are usually not diabetic. ALCOHOLIC KETOSIS Presentation a chronic alcoholic who has a binge, then stops drinking and has little or no oral food intake for a few days (ethanol and fasting) volume depletion is common and this can result in increased levels of counter regulatory hormones (eg glucagon) levels of free fatty acids (FFA) can be high (eg up to 3.5mM) providing plenty of substrate for the altered hepatic lipid metabolism to produce plenty of ketoanions GI symptoms are common (eg nausea, vomiting, abdominal pain, haematemesis, melaena) acidaemia may be severe (eg pH down to 7.0) plasma glucose may be depressed or normal or Continue reading >>

Diabetic Ketoacidosis (dka) - Topic Overview

Diabetic Ketoacidosis (dka) - Topic Overview

Diabetic ketoacidosis (DKA) is a life-threatening condition that develops when cells in the body are unable to get the sugar (glucose) they need for energy because there is not enough insulin. When the sugar cannot get into the cells, it stays in the blood. The kidneys filter some of the sugar from the blood and remove it from the body through urine. Because the cells cannot receive sugar for energy, the body begins to break down fat and muscle for energy. When this happens, ketones, or fatty acids, are produced and enter the bloodstream, causing the chemical imbalance (metabolic acidosis) called diabetic ketoacidosis. Ketoacidosis can be caused by not getting enough insulin, having a severe infection or other illness, becoming severely dehydrated, or some combination of these things. It can occur in people who have little or no insulin in their bodies (mostly people with type 1 diabetes but it can happen with type 2 diabetes, especially children) when their blood sugar levels are high. Your blood sugar may be quite high before you notice symptoms, which include: Flushed, hot, dry skin. Feeling thirsty and urinating a lot. Drowsiness or difficulty waking up. Young children may lack interest in their normal activities. Rapid, deep breathing. A strong, fruity breath odor. Loss of appetite, belly pain, and vomiting. Confusion. Laboratory tests, including blood and urine tests, are used to confirm a diagnosis of diabetic ketoacidosis. Tests for ketones are available for home use. Keep some test strips nearby in case your blood sugar level becomes high. When ketoacidosis is severe, it must be treated in the hospital, often in an intensive care unit. Treatment involves giving insulin and fluids through your vein and closely watching certain chemicals in your blood (electrolyt Continue reading >>

Diabetic Ketoacidosis

Diabetic Ketoacidosis

A Preventable Crisis People who have had diabetic ketoacidosis, or DKA, will tell you it’s worse than any flu they’ve ever had, describing an overwhelming feeling of lethargy, unquenchable thirst, and unrelenting vomiting. “It’s sort of like having molasses for blood,” says George. “Everything moves so slow, the mouth can feel so dry, and there is a cloud over your head. Just before diagnosis, when I was in high school, I would get out of a class and go to the bathroom to pee for about 10–12 minutes. Then I would head to the water fountain and begin drinking water for minutes at a time, usually until well after the next class had begun.” George, generally an upbeat person, said that while he has experienced varying degrees of DKA in his 40 years or so of having diabetes, “…at its worst, there is one reprieve from its ill feeling: Unfortunately, that is a coma.” But DKA can be more than a feeling of extreme discomfort, and it can result in more than a coma. “It has the potential to kill,” says Richard Hellman, MD, past president of the American Association of Clinical Endocrinologists. “DKA is a medical emergency. It’s the biggest medical emergency related to diabetes. It’s also the most likely time for a child with diabetes to die.” DKA occurs when there is not enough insulin in the body, resulting in high blood glucose; the person is dehydrated; and too many ketones are present in the bloodstream, making it acidic. The initial insulin deficit is most often caused by the onset of diabetes, by an illness or infection, or by not taking insulin when it is needed. Ketones are your brain’s “second-best fuel,” Hellman says, with glucose being number one. If you don’t have enough glucose in your cells to supply energy to your brain, yo 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 >>

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 >>

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 >>

Diabetic Ketoacidosis: A Serious Complication

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 >>

Diabetes With Ketone Bodies In Dogs

Diabetes With Ketone Bodies In Dogs

Studies show that female dogs (particularly non-spayed) are more prone to DKA, as are older canines. Diabetic ketoacidosis is best classified through the presence of ketones that exist in the liver, which are directly correlated to the lack of insulin being produced in the body. This is a very serious complication, requiring immediate veterinary intervention. Although a number of dogs can be affected mildly, the majority are very ill. Some dogs will not recover despite treatment, and concurrent disease has been documented in 70% of canines diagnosed with DKA. Diabetes with ketone bodies is also described in veterinary terms as diabetic ketoacidosis or DKA. It is a severe complication of diabetes mellitus. Excess ketone bodies result in acidosis and electrolyte abnormalities, which can lead to a crisis situation for your dog. If left in an untreated state, this condition can and will be fatal. Some dogs who are suffering from diabetic ketoacidosis may present as systemically well. Others will show severe illness. Symptoms may be seen as listed below: Change in appetite (either increase or decrease) Increased thirst Frequent urination Vomiting Abdominal pain Mental dullness Coughing Fatigue or weakness Weight loss Sometimes sweet smelling breath is evident Slow, deep respiration. There may also be other symptoms present that accompany diseases that can trigger DKA, such as hypothyroidism or Cushing’s disease. While some dogs may live fairly normal lives with this condition before it is diagnosed, most canines who become sick will do so within a week of the start of the illness. There are four influences that can bring on DKA: Fasting Insulin deficiency as a result of unknown and untreated diabetes, or insulin deficiency due to an underlying disease that in turn exacerba Continue reading >>

Diabetic Ketoacidosis

Diabetic Ketoacidosis

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 >>
