Acute Complications Of Diabetes - Diabetic Ketoacidosis

Acute Complications Of Diabetes - Diabetic Ketoacidosis

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

Diabetic Ketoacidosis

Diabetic Ketoacidosis

Diabetes mellitus is the name given to a group of conditions whose common hallmark is a raised blood glucose concentration (hyperglycemia) due to an absolute or relative deficiency of the pancreatic hormone insulin. In the UK there are 1.4 million registered diabetic patients, approximately 3 % of the population. In addition, an estimated 1 million remain undiagnosed. It is a growing health problem: In 1998, the World Health Organization (WHO) predicted a doubling of the worldwide prevalence of diabetes from 150 million to 300 million by 2025. For a very tiny minority, diabetes is a secondary feature of primary endocrine disease such as acromegaly (growth hormone excess) or Cushing’s syndrome (excess corticosteroid), and for these patients successful treatment of the primary disease cures diabetes. Most diabetic patients, however, are classified as suffering either type 1 or type 2 diabetes. Type 1 diabetes Type 1 diabetes, which accounts for around 15 % of the total diabetic population, is an autoimmune disease of the pancreas in which the insulin-producing β-cells of the pancreas are selectively destroyed, resulting in an absolute insulin deficiency. The condition arises in genetically susceptible individuals exposed to undefined environmental insult(s) (possibly viral infection) early in life. It usually becomes clinically evident and therefore diagnosed during late childhood, with peak incidence between 11 and 13 years of age, although the autoimmune-mediated β-cell destruction begins many years earlier. There is currently no cure and type 1 diabetics have an absolute life-long requirement for daily insulin injections to survive. Type 2 diabetes This is the most common form of diabetes: around 85 % of the diabetic population has type 2 diabetes. The primary prob Continue reading >>

Diabetic Ketoacidosis (dka)

Diabetic Ketoacidosis (dka)

Topic Overview What is diabetic ketoacidosis (DKA)? 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. What causes DKA? 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. What are the symptoms? Your blood sugar may be quite high before you notice symptoms, which include: Flushed, hot, dry skin. Blurred vision. 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. How is DKA diagnosed? 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. How is it treated? When ketoacidosis is severe, it must be treated in the hospital, often in an Continue reading >>

Diabetic Ketoacidosis

Diabetic Ketoacidosis

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

Is Keto Healthy? Ketosis Vs Ketoacidosis

Is Keto Healthy? Ketosis Vs Ketoacidosis

Is Keto Healthy? Ketosis vs Ketoacidosis When looking at a ketogenic diet and ketosis, it’s common for some people to confuse the process with a harmful, more extreme version of this state known as diabetic ketoacidosis. But there are a lot of misconceptions out there about ketosis vs ketoacidosis, and it’s time to shed some light on the subject by looking at the (very big) differences between the two. An Overview of Ketosis A ketogenic, or keto, diet is centered around the process of ketosis, so it’s important to understand exactly what ketosis is first before we get into whether or not it’s safe (spoiler: it is): Ketosis is a metabolic state where the body is primarily using fat for energy instead of carbohydrates. Burning carbohydrates (glucose) for energy is the default function of the body, so if glucose is available, the body will use that first. But during ketosis, the body is using ketones instead of glucose. This is an amazing survival adaptation by the body for handling periods of famine or fasting, extreme exercise, or anything else that leaves the body without enough glucose for fuel. Those eating a ketogenic diet purposely limit their carb intake (usually between 20 and 50 grams per day) to facilitate this response. That’s why the keto diet focuses on very low carb intake, moderate to low protein intake, and high intakes of dietary fats. Lower protein is important because it prevents the body from pulling your lean muscle mass for energy and instead turns to fat. Ketone bodies are released during ketosis and are created by the liver from fatty acids. These ketones are then used by the body to power all of its biggest organs, including the brain, and they have many benefits for the body we’ll get into later. But first, let’s address a common mi Continue reading >>

Diabetic Ketoacidosis

Diabetic Ketoacidosis

DKA is usually signaled by high blood sugar levels. The important fact to remember is that without enough insulin, the body cannot burn glucose properly and fat comes out of fat cells. Diabetic Ketoacidosis (DKA) – a condition brought on by inadequate insulin – is a life-threatening emergency usually affecting people with type 1 diabetes. Although less common, it also can happen when you have type 2 diabetes. DKA is usually, but not always, signaled by high blood sugar levels. The important fact to remember is that without enough insulin, the body cannot burn glucose properly and fat comes out of fat cells. As a consequence the excess fat goes to the liver and glucose builds up in the bloodstream. The liver makes ketoacids (also known as ketones) out of the fat. Before long, the body is literally poisoning itself with excess glucose and ketoacids. What causes DKA? A lack of insulin usually due to: Unknown or newly diagnosed cases of type 1 diabetes Missed or inadequate doses of insulin, or spoiled insulin Infection Steroid medications An extremely stressful medical condition DKA is rare in type 2 diabetes – but can develop if someone with type 2 diabetes gets another serious medical condition. Examples of medical conditions associated with DKA in type 2 diabetes are severe infections, acute pancreatitis (inflammation of the insulin producing organ, the pancreas), and treatment with steroids. Symptoms of DKA include: Nausea, vomiting Stomach pain Fruity breath – the smell of ketoacids Frequent urination Excessive thirst Weakness, fatigue Speech problems, confusion or unconsciousness Heavy, deep breathing How do you know if you have DKA? Check your blood or urine for ketones. And if the test is positive, you will need immediate medical care. Treatment includes agg Continue reading >>

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. What is diabetic ketoacidosis? 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 f Continue reading >>

Alcoholic Ketoacidosis

Alcoholic Ketoacidosis

Alcoholic ketoacidosis is a metabolic complication of alcohol use and starvation characterized by hyperketonemia and anion gap metabolic acidosis without significant hyperglycemia. Alcoholic ketoacidosis causes nausea, vomiting, and abdominal pain. Diagnosis is by history and findings of ketoacidosis without hyperglycemia. Treatment is IV saline solution and dextrose infusion. Alcoholic ketoacidosis is attributed to the combined effects of alcohol and starvation on glucose metabolism. Alcohol diminishes hepatic gluconeogenesis and leads to decreased insulin secretion, increased lipolysis, impaired fatty acid oxidation, and subsequent ketogenesis, causing an elevated anion gap metabolic acidosis. Counter-regulatory hormones are increased and may further inhibit insulin secretion. Plasma glucose levels are usually low or normal, but mild hyperglycemia sometimes occurs. Diagnosis requires a high index of suspicion; similar symptoms in an alcoholic patient may result from acute pancreatitis, methanol or ethylene glycol poisoning, or diabetic ketoacidosis (DKA). In patients suspected of having alcoholic ketoacidosis, serum electrolytes (including magnesium), BUN and creatinine, glucose, ketones, amylase, lipase, and plasma osmolality should be measured. Urine should be tested for ketones. Patients who appear significantly ill and those with positive ketones should have arterial blood gas and serum lactate measurement. The absence of hyperglycemia makes DKA improbable. Those with mild hyperglycemia may have underlying diabetes mellitus, which may be recognized by elevated levels of glycosylated Hb (HbA1c). Typical laboratory findings include a high anion gap metabolic acidosis, ketonemia, and low levels of potassium, magnesium, and phosphorus. Detection of acidosis may be com Continue reading >>

Childhood Ketoacidosis

Childhood Ketoacidosis

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 one of our health articles more useful. Diabetic ketoacidosis (DKA) is the leading cause of mortality in childhood diabetes.[1]The primary cause of DKA is absolute or relative insulin deficiency: Absolute - eg, previously undiagnosed type 1 diabetes mellitus or a patient with known type 1 diabetes who does not take their insulin. Relative - stress causes a rise in counter-regulatory hormones with relative insulin deficiency. DKA can be fatal The usual causes of death are: Cerebral oedema - associated with 25% mortality (see 'Cerebral odedema', below). Hypokalaemia - which is preventable with good monitoring. Aspiration pneumonia - thus, use of a nasogastric tube in the semi-conscious or unconscious is advised. Deficiency of insulin. Rise in counter-regulatory hormones, including glucagon, cortisol, growth hormone, and catecholamines. Thus, inappropriate gluconeogenesis and liver glycogenolysis occur compounding the hyperglycaemia, which causes hyperosmolarity and ensuing polyuria, dehydration and loss of electrolytes. Accelerated catabolism from lipolysis of adipose tissue leads to increased free fatty acid circulation, which on hepatic oxidation produces the ketone bodies (acetoacetic acid and beta-hydroxybutyric acid) that cause the metabolic acidosis. A vicious circle is usually set up as vomiting usually occurs compounding the stress and dehydration; the cycle can only be broken by providing insulin and fluids; otherwise, severe acidosis occurs and can be fatal. Biochemical criteria The biochemical criteria required for a diagnosis of DKA to be made are Continue reading >>

Ketoacidosis

Ketoacidosis

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.[1] 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.[2] 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[edit] Three common causes of ketoacidosis are alcohol, starvation, and diabetes, resulting in alcoholic ketoacidosis, starvation ketoacidosis, and diabetic ketoacidosis respectively.[3] In diabetic ketoacidosis, a high concentration of ketone bodies is usually accomp Continue reading >>

Cardiovascular Complications Of Ketoacidosis

Cardiovascular Complications Of Ketoacidosis

US Pharm. 2016;41(2):39-42. ABSTRACT: Ketoacidosis is a serious medical emergency requiring hospitalization. It is most commonly associated with diabetes and alcoholism, but each type is treated differently. Some treatments for ketoacidosis, such as insulin and potassium, are considered high-alert medications, and others could result in electrolyte imbalances. Several cardiovascular complications are associated with ketoacidosis as a result of electrolyte imbalances, including arrhythmias, ECG changes, ventricular tachycardia, and cardiac arrest, which can be prevented with appropriate initial treatment. Acute myocardial infarction can predispose patients with diabetes to ketoacidosis and worsen their cardiovascular outcomes. Cardiopulmonary complications such as pulmonary edema and respiratory failure have also been seen with ketoacidosis. Overall, the mortality rate of ketoacidosis is low with proper and urgent medical treatment. Hospital pharmacists can help ensure standardization and improve the safety of pharmacotherapy for ketoacidosis. In the outpatient setting, pharmacists can educate patients on prevention of ketoacidosis and when to seek medical attention. Metabolic acidosis occurs as a result of increased endogenous acid production, a decrease in bicarbonate, or a buildup of endogenous acids.1 Ketoacidosis is a metabolic disorder in which regulation of ketones is disrupted, leading to excess secretion, accumulation, and ultimately a decrease in the blood pH.2 Acidosis is defined by a serum pH <7.35, while a pH <6.8 is considered incompatible with life.1,3 Ketone formation occurs by breakdown of fatty acids. Insulin inhibits beta-oxidation of fatty acids; thus, low levels of insulin accelerate ketone formation, which can be seen in patients with diabetes. Extr Continue reading >>
