What Is A Ketoacidosis Coma?

Diabetic Coma Recovery: What You Need To Know

Diabetic Coma Recovery: What You Need To Know

In people with diabetes, a diabetic coma occurs when severe levels of either high or low uncontrolled blood sugar are not corrected. If treated quickly, a person will make a rapid recovery from a diabetic coma. However, diabetic coma can be fatal or result in brain damage. It is important for people with diabetes to control their blood sugars and know what to do when their blood sugar levels are not within their target range. The severe symptoms of uncontrolled blood sugar that can come before a diabetic coma include vomiting, difficulty breathing, confusion, weakness, and dizziness. Recovery from diabetic coma If a diabetic coma is not treated within a couple of hours of it developing, it can cause irreversible brain damage. If no treatment is received, a diabetic coma will be fatal. In addition, having blood sugar levels that continue to be too low or too high can be bad for long-term health. This remains true even if they do not develop into diabetic coma. Recognizing the early signs of low or high blood sugar levels and regular monitoring can help people with diabetes keep their blood sugar levels within the healthy range. Doing so will also reduce the risk of associated complications and diabetic coma. What is diabetes? Diabetes is a long-term condition in which the body is unable to control the level of a sugar called glucose in the blood. Diabetes is caused by either a lack of insulin, the body's inability to use insulin correctly, or both. In people who don't have diabetes, insulin usually ensures that excess glucose is removed from the bloodstream. It does this by stimulating cells to absorb the glucose they need for energy from the blood. Insulin also causes any remaining glucose to be stored in the liver as a substance called glycogen. The production of insul 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.

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 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

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 >>

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 >>

Diabetic Coma

Diabetic Coma

Tweet Coma is relatively rare in diagnosed diabetes but it is very important to be aware of the situations that increase risk of coma. Causes of diabetic coma The main causes of coma occurring in people with diabetes are as a result of very low or very high blood glucose levels. The three most common causes of coma in people with diabetes are: Severe hypoglycemia and coma Severe hypoglycemia (very low blood glucose levels) can lead to loss of consciousness and coma if not treated. In most cases the body will restore blood sugar levels to normal by releasing glucagon to raise blood sugar levels. Coma is more likely to occur from low blood glucose levels if: A large insulin overdose is taken Alcohol is in the body during hypoglycemia Exercise has depleted the body’s glycogen supply Diabetic ketoacidosis and coma Diabetic ketoacidosis is a dangerous state of having very high blood glucose levels (typically above 17 mmol/L) in combination with high ketone levels. Ketoacidosis is able to occur if the body runs out of insulin and is therefore a factor for people with type 1 diabetes to be aware of. Insulin can prevent ketone levels rising and this is the key reason why people with diabetes are advised never to miss their long term (basal) insulin injections. The symptoms of ketoacidosis include nausea, vomiting, dehydration, disorientation and deep, laboured breathing. If someone with diabetes is displaying these symptoms call for emergency medical help as loss of consciousness and coma could follow. Illness in type 1 diabetes can lead to high blood glucose and ketone levels. It is advisable to test for ketones during periods of illness to prevent ketoacidosis developing. Diabetic coma at diagnosis of type 1 diabetes If the symptoms of type 1 diabetes are not spotted soon e Continue reading >>

What Is The Difference Between Insulin Shock & A Diabetic Coma?

What Is The Difference Between Insulin Shock & A Diabetic Coma?

Nearly 26 million Americans had diabetes in 2010, and many were not being adequately treated, according to the Centers for Disease Control and Prevention. Most people have heard about the long-term complications of poorly controlled diabetes, such as kidney failure, cardiovascular disease and blindness. People with diabetes can also develop acute complications. If your blood glucose gets too high due to inadequate treatment, or falls too low due to overly aggressive treatment, you could suddenly lose consciousness. Insulin shock, diabetic ketoacidosis and hyperglycemic hyperosmolar syndrome are all potential causes of diabetic coma. Insulin Shock Insulin is a hormone your pancreas normally produces in response to rising glucose levels. Many people with diabetes must take insulin to prevent their blood glucose from rising too high. If you take more insulin than your body needs, you could suddenly develop hypoglycemia, or low blood glucose. People who take insulin and exercise without eating or drink too much alcohol are particularly susceptible to hypoglycemia. Insulin shock, which is a form of diabetic coma, may occur if your blood glucose falls too low to support your brain’s metabolic demands -- usually below 50 mg/dL. Seizures may occur before the onset of coma. Diabetic Ketoacidosis Just as a low blood glucose level can trigger unconsciousness, extremely high blood glucose levels can alter brain function and lead to coma. Diabetic ketoacidosis, which usually affects people with type 1 diabetes, happens when you don’t have enough insulin in your system. DKA may be the initial manifestation of newly developed diabetes, or it may result from a skipped insulin dose in a person who has already been diagnosed with diabetes. Infections and alcohol abuse can also trigge Continue reading >>

Understanding And Treating Diabetic Ketoacidosis

Understanding And Treating Diabetic Ketoacidosis

Diabetic ketoacidosis (DKA) is a serious metabolic disorder that can occur in animals with diabetes mellitus (DM).1,2 Veterinary technicians play an integral role in managing and treating patients with this life-threatening condition. In addition to recognizing the clinical signs of this disorder and evaluating the patient's response to therapy, technicians should understand how this disorder occurs. DM is caused by a relative or absolute lack of insulin production by the pancreatic b-cells or by inactivity or loss of insulin receptors, which are usually found on membranes of skeletal muscle, fat, and liver cells.1,3 In dogs and cats, DM is classified as either insulin-dependent (the body is unable to produce sufficient insulin) or non-insulin-dependent (the body produces insulin, but the tissues in the body are resistant to the insulin).4 Most dogs and cats that develop DKA have an insulin deficiency. Insulin has many functions, including the enhancement of glucose uptake by the cells for energy.1 Without insulin, the cells cannot access glucose, thereby causing them to undergo starvation.2 The unused glucose remains in the circulation, resulting in hyperglycemia. To provide cells with an alternative energy source, the body breaks down adipocytes, releasing free fatty acids (FFAs) into the bloodstream. The liver subsequently converts FFAs to triglycerides and ketone bodies. These ketone bodies (i.e., acetone, acetoacetic acid, b-hydroxybutyric acid) can be used as energy by the tissues when there is a lack of glucose or nutritional intake.1,2 The breakdown of fat, combined with the body's inability to use glucose, causes many pets with diabetes to present with weight loss, despite having a ravenous appetite. If diabetes is undiagnosed or uncontrolled, a series of metab Continue reading >>

Diabetic Ketoacidosis And Hyperglycemic Hyperosmolar Syndrome

Diabetic Ketoacidosis And Hyperglycemic Hyperosmolar Syndrome

In Brief Diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic syndrome (HHS) are two acute complications of diabetes that can result in increased morbidity and mortality if not efficiently and effectively treated. Mortality rates are 2–5% for DKA and 15% for HHS, and mortality is usually a consequence of the underlying precipitating cause(s) rather than a result of the metabolic changes of hyperglycemia. Effective standardized treatment protocols, as well as prompt identification and treatment of the precipitating cause, are important factors affecting outcome. The two most common life-threatening complications of diabetes mellitus include diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar syndrome (HHS). Although there are important differences in their pathogenesis, the basic underlying mechanism for both disorders is a reduction in the net effective concentration of circulating insulin coupled with a concomitant elevation of counterregulatory hormones (glucagon, catecholamines, cortisol, and growth hormone). These hyperglycemic emergencies continue to be important causes of morbidity and mortality among patients with diabetes. DKA is reported to be responsible for more than 100,000 hospital admissions per year in the United States1 and accounts for 4–9% of all hospital discharge summaries among patients with diabetes.1 The incidence of HHS is lower than DKA and accounts for <1% of all primary diabetic admissions.1 Most patients with DKA have type 1 diabetes; however, patients with type 2 diabetes are also at risk during the catabolic stress of acute illness.2 Contrary to popular belief, DKA is more common in adults than in children.1 In community-based studies, more than 40% of African-American patients with DKA were >40 years of age and more than 2 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

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 >>

Coma With Diffuse White Matter Hemorrhages In Juvenile Diabetic Ketoacidosis

Coma With Diffuse White Matter Hemorrhages In Juvenile Diabetic Ketoacidosis

Abstract Cerebral edema is the most common neurologic complication of diabetic ketoacidosis in children. A minority of young patients with intracerebral crises in diabetic ketoacidosis present with cerebrovascular accidents. We report 2 adolescent patients with diabetic ketoacidosis who presented with coma and diffuse white matter hemorrhages in the absence of either cerebral edema or cerebrovascular accidents. These 2 cases illustrate a novel clinical and neuropathologic description of diffuse white matter hemorrhages, possibly related to a cytotoxic process as the underlying mechanism. These case descriptions emphasize that pediatric patients with diabetic ketoacidosis and coma can present with pathology not related to either cerebral edema or cerebrovascular accidents.

What You Should Know About Recovery From Diabetic Coma

What You Should Know About Recovery From Diabetic Coma

A diabetic coma occurs when a person with diabetes loses consciousness. It can occur in people with type 1 or type 2 diabetes. A diabetic coma occurs when blood sugar levels become either too low or too high. The cells in your body require glucose to function. High blood sugar, or hyperglycemia, can make you feel lightheaded and lose consciousness. Low blood sugar, or hypoglycemia, can cause dehydration to the point where you may lose consciousness. Usually, you can prevent hyperglycemia or hypoglycemia from progressing to a diabetic coma. If a diabetic coma occurs, it’s likely that your doctor can balance your blood glucose levels and restore your consciousness and health quickly if they can respond to your condition in a timely manner. You can also slip into a diabetic coma if you develop diabetic ketoacidosis. Diabetic ketoacidosis (DKA) is a buildup of chemicals called ketones in your blood. Hypoglycemia The symptoms of hypoglycemia may include: headache fatigue dizziness confusion heart palpitations shakiness Hyperglycemia If you have hyperglycemia, you may experience noticeably increased thirst and you may urinate more frequently. A blood test would also reveal higher levels of glucose in your blood stream. A urine test can also show that your glucose levels are too high. DKA causes high levels of blood glucose. The symptoms also include increased thirst and a frequent need to urinate. Other symptoms of elevated ketone levels include: feeling tired having an upset stomach having flushed or dry skin If you have more severe diabetic coma symptoms, call 911. Severe symptoms may include: vomiting difficulty breathing confusion weakness dizziness A diabetic coma is a medical emergency. It can lead to brain damage or death if you don’t get treatment.

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.
