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 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.

Diabetic Ketoacidosis Causes, Symptoms, Treatment, And Complications
Diabetic ketoacidosis definition and facts Diabetic ketoacidosis is a life-threatening complication of type 1 diabetes (though rare, it can occur in people with type 2 diabetes) that occurs when the body produces high levels of ketones due to lack of insulin. Diabetic ketoacidosis occurs when the body cannot produce enough insulin. The signs and symptoms of diabetic ketoacidosis include Risk factors for diabetic ketoacidosis are type 1 diabetes, and missing insulin doses frequently, or being exposed to a stressor requiring higher insulin doses (infection, etc). Diabetic ketoacidosis is diagnosed by an elevated blood sugar (glucose) level, elevated blood ketones and acidity of the blood (acidosis). The treatment for diabetic ketoacidosis is insulin, fluids and electrolyte therapy. Diabetic ketoacidosis can be prevented by taking insulin as prescribed and monitoring glucose and ketone levels. The prognosis for a person with diabetic ketoacidosis depends on the severity of the disease and the other underlying medical conditions. Diabetic ketoacidosis (DKA) is a severe and life-threatening complication of diabetes. Diabetic ketoacidosis occurs when the cells in our body do not receive the sugar (glucose) they need for energy. This happens while there is plenty of glucose in the bloodstream, but not enough insulin to help convert glucose for use in the cells. The body recognizes this and starts breaking down muscle and fat for energy. This breakdown produces ketones (also called fatty acids), which cause an imbalance in our electrolyte system leading to the ketoacidosis (a metabolic acidosis). The sugar that cannot be used because of the lack of insulin stays in the bloodstream (rather than going into the cell and provide energy). The kidneys filter some of the glucose (suga Continue reading >>
Effects Of Diabetes On The Body And Organs
Over time, the raised blood sugar levels that result from diabetes can cause a wide range of serious health issues. But what do these health issues involve, and how are the organs of the body affected? Can these effects be minimized? When people have diabetes, the body either does not make enough insulin or cannot use what it has effectively. As a result, the amount of sugar in the blood becomes higher than it should be. Glucose, or blood sugar, is the main power source for the human body. It comes from the food people eat. The hormone insulin helps the cells of the body convert glucose into fuel. Fortunately, taking a proactive approach to this chronic disease through medical care, lifestyle changes, and medication can help limit its effects. Effect on systems and organs The effects of diabetes can be seen on systems throughout the body, including: The circulatory system Diabetes can damage large blood vessels, causing macrovascular disease. It can also damage small blood vessels, causing what is called microvascular disease. Complications from macrovascular disease include heart attack and stroke. However, macrovascular disease can be prevented by: Microvascular disease can cause eye, kidney, and nerve problems, but good control of diabetes can help prevent these complications. The cardiovascular system Excess blood sugar decreases the elasticity of blood vessels and causes them to narrow, impeding blood flow. The National Heart, Lung, and Blood Institute say diabetes is as big a risk factor for heart disease as smoking or high cholesterol. According to the Centers for Disease Control and Prevention (CDC), the risk of stroke or dying of heart disease increases by 200-400 percent for adults with diabetes. The nervous system When people have diabetes, they can develop n Continue reading >>
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 >>
The Effects Of Diabetes On Your Body
When you hear the word “diabetes,” your first thought is likely about high blood sugar. Blood sugar is an often-underestimated component of your health. When it’s out of whack over a long period of time, it could develop into diabetes. Diabetes affects your body’s ability to produce or use insulin, a hormone that allows your body to turn glucose (sugar) into energy. Here’s what symptoms may occur to your body when diabetes takes effect. Diabetes can be effectively managed when caught early. However, when left untreated, it can lead to potential complications that include heart disease, stroke, kidney damage, and nerve damage. Normally after you eat or drink, your body will break down sugars from your food and use them for energy in your cells. To accomplish this, your pancreas needs to produce a hormone called insulin. Insulin is what facilitates the process of pulling sugar from the blood and putting it in the cells for use, or energy. If you have diabetes, your pancreas either produces too little insulin or none at all. The insulin can’t be used effectively. This allows blood glucose levels to rise while the rest of your cells are deprived of much-needed energy. This can lead to a wide variety of problems affecting nearly every major body system. The effects of diabetes on your body also depends on the type you have. There are two main types of diabetes: type 1 and type 2. Type 1, also called juvenile diabetes or insulin-dependent diabetes, is an immune system disorder. Your own immune system attacks the insulin-producing cells in the pancreas, destroying your body’s ability to make insulin. With type 1 diabetes, you must take insulin to live. Most people are diagnosed as a child or young adult. Type 2 is related to insulin resistance. It used to occur i Continue reading >>
What is diabetic ketoacidosis? Diabetic ketoacidosis is a complication of diabetes that occurs when compounds called ketones build up in the bloodstream. Ketones are produced when the body breaks down fats instead of sugars, which happens when the body does not produce enough insulin to process sugar properly. Ketoacidosis generally develops in people with type 1 diabetes, a chronic condition in which the pancreas produces too little or no insulin. It can also happen, although uncommonly, in those with type 2 diabetes, a chronic condition in which your body is either resistant to insulin or your pancreas does not produce enough insulin. Symptoms worsen over time as the body attempts to use fat instead of sugar for energy. Blood sugar levels generally increase dramatically during the development of diabetic ketoacidosis, as the liver attempts to compensate for the lack of sugar-derived energy. Diabetic ketoacidosis can lead to rapid breathing, flushing, fruity-smelling breath, nausea, vomiting, pain, fatigue, headache, and muscle stiffness. In severe cases, ketoacidosis can lead to a slowing of mental activity that can progress to a coma. The consequences of ketoacidosis can be severe, even life threatening, but modern treatments are usually very effective at preventing serious complications if treatment is obtained early. Seek immediate medical care (call 911) for serious symptoms of ketoacidosis, such as decreased consciousness, difficulty breathing, mental stupor, or unexplained fruity-smelling breath. Seek prompt medical care for any symptoms of diabetes or high blood glucose levels, as early treatment is critical for preventing life-threatening complications. Continue reading >>
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 >>
Which Systems Of The Body Are Affected By Diabetes?
Diabetes mellitus is a metabolic disorder in which inadequate production of the hormone insulin or a resistance to its actions in the body can lead to high blood sugar levels. Insulin is needed to get sugar into cells of the body, where it is used for energy. When sugar cannot get into cells, it remains in the blood at high levels. Complications of diabetes arise from long-term exposure to high blood sugar. The cardiovascular, nervous, visual and urinary systems are most commonly affected by chronically high blood sugars. Video of the Day The cardiovascular system includes the heart and blood vessels. High blood sugar and increased blood fat levels commonly found in people with diabetes contribute to fatty deposits called plaques on the inner walls of blood vessels, causing inflammation. This leads to decreased blood flow and hardening of the blood vessels called atherosclerosis. High blood sugar also results in glycation, where sugars attach to proteins, making them sticky. This occurs on proteins found in blood vessels, also resulting in inflammation. When this occurs in the heart, it can lead to cardiovascular disease. According to a 2016 report from the American Heart Association, 68 percent of people with diabetes older than 65 die of heart disease. Nerve damage called diabetic neuropathy is common in people with diabetes. Symptoms typically appear after several years but may be present when diabetes is diagnosed, as the disease may have gone undetected for many years. Diabetic nerve damage known as peripheral neuropathy is most common in the legs and feet. According to a 2005 statement by the American Diabetes Association, up to 50 percent of people with diabetes have peripheral neuropathy. This typically starts as numbness or tingling that progresses to loss of p Continue reading >>
Respiratory System And Diabetes
Tweet The respiratory system is the system of organs that allow the body to take in oxygen and expel carbon dioxide, this process is known as gaseous exchange. We generally breathe between 12 and 20 times a minute. There are a number of complications of diabetes that can negatively affect our breathing. Parts of the respiratory system The following parts of the body make up the respiratory system: Mouth and nose Trachea (windpipe) Lungs Diaphragm How the respiratory system works Breathing is usually initiated by contraction of the diaphragm, a muscle which separates the chest cavity from the abdomen. As the diaphragm contracts, more space is made available in the chest cavity and this has the effect of creating suction as the lungs expand to fill the space. The lungs draw in air through the nose and/or mouth which then travels down the trachea (windpipe) before reaching the lungs. Within the lungs are tiny air sacs called alveoli which allow oxygen from the air we breathe to be absorbed into the many tiny blood vessels contained with the alveoli. As this happens, the alveoli take in carbon dioxide from the blood vessels and this completes gaseous exchange. With gaseous exchange complete, the diaphragm relaxes and the carbon dioxide rich air in the lungs is expelled via the trachea out of the mouth and/or nose. The lungs As noted above, it is within the lungs that the gaseous exchange of oxygen and carbon dioxide takes place. The lungs are filled with a branched structure of airways called bronchi and smaller airways called bronchioles. Located at the end of the bronchioles are the alveoli in which the exchange of gases takes place. The average capacity of human lungs is between 4 and 6 litres of air. The capacity of lungs may be reduced if the lungs become diseased or d Continue reading >>
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 >>
What is diabetic ketoacidosis? Diabetic ketoacidosis (DKA) is a life-threatening condition caused by a build-up of waste products called ketones in the blood. It occurs in people with diabetes mellitus when they have no, or very low levels of, insulin. DKA mostly occurs in people with type 1 diabetes, but it can also occur in some people with type 2 diabetes and pregnant women with gestational diabetes. Causes Glucose is an essential energy source for the body's cells. When food containing carbohydrates is eaten, it is broken down into glucose that travels around the body in the blood, to be absorbed by cells that use it for energy. Insulin works to help glucose pass into cells. Without insulin, the cells cannot absorb glucose to use for energy. This leads to a series of changes in metabolism that can affect the whole body. The liver attempts to compensate for the lack of energy in the cells by producing more glucose, leading to increased levels of glucose in the blood, also known as hyperglycaemia. The body switches to burning its stores of fat instead of glucose to produce energy. This leads to a build-up of acidic waste products called ketones in the blood and urine. This is known as ketoacidosis, and it can cause heart rhythm abnormalities, breathing changes and abdominal pain. The kidneys try to remove some of the excess glucose and ketones. However, this requires taking large amounts of fluid from the body, which leads to dehydration. This can cause: Increased concentration of ketones in the blood, worsening the ketoacidosis; Loss of electrolytes such as potassium and salt that are vital for the normal function of the body's cells, and; Signs and symptoms Symptoms of DKA can develop over the course of hours. They can include: Increased thirst; Increased frequency Continue reading >>
Diabetic Ketoacidosis (dka)
Diabetes is a long-term condition that can have a major impact on the life of a child or young person, as well as their family or carers. In addition to insulin therapy, diabetes management should include education, support and access to psychological services, as detailed here and in this guideline. Preparations should also be made for the transition from paediatric to adult services, which have a somewhat different model of care and evidence base. Rapid‐acting insulin analogues (artificial insulin such as insulin lispro, insulin aspart, or insulin glulisine) act more quickly than regular human insulin. In people with a specific type of life‐threatening diabetic coma due to uncontrolled diabetes, called diabetic ketoacidosis, prompt administration of intravenous regular insulin is standard therapy. The rapid‐acting insulin analogues, if injected subcutaneously, act faster than subcutaneously administered regular insulin. The need for a continuous intravenous infusion, an intervention that usually requires admission to an intensive care unit, can thereby be avoided. This means that subcutaneously given insulin analogues for diabetic ketoacidosis might be applied in the emergency department and a general medicine ward. Type 1 diabetes affects over 370,000 adults in the UK, representing approximately 10% of adults diagnosed with diabetes. Given the complexity of its treatment regimens, successful outcomes depend, perhaps more than with any other long-term condition, on full engagement of the adult with type 1 diabetes in life-long day-by-day self-management. In order to support this, the health service needs to provide informed, expert support, education and training as well as a range of other more conventional biomedical services and interventionsfor the preventio Continue reading >>
Diabetic ketoacidosis (DKA) is a potentially life-threatening complication of diabetes mellitus. Signs and symptoms may include vomiting, abdominal pain, deep gasping breathing, increased urination, weakness, confusion, and occasionally loss of consciousness. A person's breath may develop a specific smell. Onset of symptoms is usually rapid. In some cases people may not realize they previously had diabetes. DKA happens most often in those with type 1 diabetes, but can also occur in those with other types of diabetes under certain circumstances. Triggers may include infection, not taking insulin correctly, stroke, and certain medications such as steroids. DKA results from a shortage of insulin; in response the body switches to burning fatty acids which produces acidic ketone bodies. DKA is typically diagnosed when testing finds high blood sugar, low blood pH, and ketoacids in either the blood or urine. The primary treatment of DKA is with intravenous fluids and insulin. Depending on the severity, insulin may be given intravenously or by injection under the skin. Usually potassium is also needed to prevent the development of low blood potassium. Throughout treatment blood sugar and potassium levels should be regularly checked. Antibiotics may be required in those with an underlying infection. In those with severely low blood pH, sodium bicarbonate may be given; however, its use is of unclear benefit and typically not recommended. Rates of DKA vary around the world. 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. DKA was first described in 1886 and, until the introduction of insulin therapy in the 1920s, it was almost univ Continue reading >>
How Does Ketoacidosis Affect The Human Brain?
Diabetic Ketoacidosis (DKA) is the body’s emergency reaction to glucose starvation in the absence of insulin. It is a disastrous reaction — in general, it makes things worse rather than better, and starts a vicious cycle of blood acidity, rising blood glucose, dehydration, and blood hyperosmolality (high concentration of dissolved stuff) that can be hard to break. One of the hardest-hit organs in DKA is the brain, due to the dehydration and acidic blood entering that sensitive organ. Severe DKA may lead to brain swelling (edema) which is life-threatening. But recent studies have shown that even a short, apparently fully-recovered stint of DKA leads to measurable brain injury. Diabetic Ketoacidosis (DKA) is a life–threatening consequence of diabetes. DKA occurs when there is a lack of insulin in the body causing hyperglycemia. As a result of the inability of glucose to enter the cells, the body must find other means to obtain energy. As such, fat breakdown occurs resulting in the accumulation of fatty acids. The fatty acids are metabolized to ketones that cause the blood to become acidotic (pH less than7.3). Because glucose remains in the blood, there is an increase in thirst and drinking to eliminate the solute load of glucose, which also results in increased urination (polyuria and polydipsia). Thus, the combination of increased serum acidity, weight loss, polyuria, and polydipsia may lead to extreme dehydration, coma, or brain damage. Without a doubt, the most severe acute complication of DKA is cerebral edema. Many cases of new onset type 1 diabetes present DKA (15-70 percent depending on age and geographic region, according to multiple studies), hence the importance of an early diagnosis of diabetes in order to avoid potential consequences. Much research is be Continue reading >>
