Complications Of Untreated Dka

Diabetic Ketoacidosis

Diabetic Ketoacidosis

As fat is broken down, acids called ketones build up in the blood and urine. In high levels, ketones are poisonous. This condition is known as ketoacidosis. Diabetic ketoacidosis (DKA) is sometimes the first sign of type 1 diabetes in people who have not yet been diagnosed. It can also occur in someone who has already been diagnosed with type 1 diabetes. Infection, injury, a serious illness, missing doses of insulin shots, or surgery can lead to DKA in people with type 1 diabetes. People with type 2 diabetes can also develop DKA, but it is less common. It is usually triggered by uncontrolled blood sugar, missing doses of medicines, or a severe illness. Continue reading >>

Diabetes Complications In Dogs And Cats: Diabetes Ketoacidosis (dka)

Diabetes Complications In Dogs And Cats: Diabetes Ketoacidosis (dka)

Unfortunately, we veterinarians are seeing an increased prevalence of diabetes mellitus in dogs and cats. This is likely due to the growing prevalence of obesity (secondary to inactive lifestyle, a high carbohydrate diet, lack of exercise, etc.). So, if you just had a dog or cat diagnosed with diabetes mellitus, what do you do? First, we encourage you to take a look at these articles for an explanation of the disease: Diabetes Mellitus (Sugar Diabetes) in Dogs Once you have a basic understanding of diabetes mellitus (or if you already had one), this article will teach you about life-threatening complications that can occur as a result of the disease; specifically, I discuss a life-threatening condition called diabetes ketoacidosis (DKA) so that you know how to help prevent it! What is DKA? When diabetes goes undiagnosed, or when it is difficult to control or regulate, the complication of DKA can occur. DKA develops because the body is so lacking in insulin that the sugar can’t get into the cells -- resulting in cell starvation. Cell starvation causes the body to start breaking down fat in an attempt to provide energy (or a fuel source) to the body. Unfortunately, these fat breakdown products, called “ketones,” are also poisonous to the body. Symptoms of DKA Clinical signs of DKA include the following: Weakness Not moving (in cats, hanging out by the water bowl) Not eating to complete anorexia Large urinary clumps in the litter box (my guideline? If it’s bigger than a tennis ball, it’s abnormal) Weight loss (most commonly over the back), despite an overweight body condition Excessively dry or oily skin coat Abnormal breath (typically a sweet “ketotic” odor) In severe cases DKA can also result in more significant signs: Abnormal breathing pattern Jaundice Ab Continue reading >>

Diabetic Ketoacidosis

Diabetic Ketoacidosis

Diabetic ketoacidosis (DKA) is a serious complications of untreated diabetes. In this complication, severely insufficient insulin levels in the body results into high blood sugar that leads to the production and buildup of ketones in the blood. These ketones are slightly acidic, and large amounts of them can lead to ketoacidosis. If remained untreated, the condition leads to diabetic coma and may be fatal. Diabetic ketoacidosis (DKA) gets triggered by a stressful event on the body, such as an illness or severe lack of insulin. DKA is more common in people with type 1 diabetes. In some cases, identification of DKA is the first indication that a person has diabetes. Early Sluggish and extreme tiredness Fruity smell to breath (like acetone) Extreme thirst, despite large fluid intake Constant urination/bedwetting Extreme weight loss Presence of Oral Thrush or yeast infections that fail to go away Muscle wasting Agitation / Irritation / Aggression / Confusion Late At this stage, Diabetic ketoacidosis reaches a life-threatening level: Vomiting. Although this can be a sign of hyperglycemia and isn't always a late-stage sign, it can occur with or without ketoacidosis. Confusion Abdominal pain Loss of appetite Flu-like symptoms Unconsciousness (diabetic coma) Being lethargic and apathetic Extreme weakness Kussmaul breathing (air hunger). In this condition, patients breathe more deeply and/or more rapidly The major risk factors accelerating on set of diabetic ketoacidosis include the following: Diabetes mellitus: Type 1 diabetics are at a higher risk of DKA, because they must rely on outside insulin sources for survival. DKA can occur in patients with type 2, particularly in obese children. Age: DKA may occur at any age, but younger people below 19 years of age are more susceptib Continue reading >>

Diabetic Ketoacidosis Causes, Symptoms, Treatment, And Complications

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 >>

Ketoacidosis: A Complication Of Diabetes

Ketoacidosis: A Complication Of Diabetes

Diabetic ketoacidosis is a serious condition that can occur as a complication of diabetes. People with diabetic ketoacidosis (DKA) have high blood sugar levels and a build-up of chemicals called ketones in the body that makes the blood more acidic than usual. Diabetic ketoacidosis can develop when there isn’t enough insulin in the body for it to use sugars for energy, so it starts to use fat as a fuel instead. When fat is broken down to make energy, ketones are made in the body as a by-product. Ketones are harmful to the body, and diabetic ketoacidosis can be life-threatening. Fortunately, treatment is available and is usually successful. Symptoms Ketoacidosis usually develops gradually over hours or days. Symptoms of diabetic ketoacidosis may include: excessive thirst; increased urination; tiredness or weakness; a flushed appearance, with hot dry skin; nausea and vomiting; dehydration; restlessness, discomfort and agitation; fruity or acetone smelling breath (like nail polish remover); abdominal pain; deep or rapid breathing; low blood pressure (hypotension) due to dehydration; and confusion and coma. See your doctor as soon as possible or seek emergency treatment if you develop symptoms of ketoacidosis. Who is at risk of diabetic ketoacidosis? Diabetic ketoacidosis usually occurs in people with type 1 diabetes. It rarely affects people with type 2 diabetes. DKA may be the first indication that a person has type 1 diabetes. It can also affect people with known diabetes who are not getting enough insulin to meet their needs, either due to insufficient insulin or increased needs. Ketoacidosis most often happens when people with diabetes: do not get enough insulin due to missed or incorrect doses of insulin or problems with their insulin pump; have an infection or illne Continue reading >>

Diabetic Ketoacidosis - Symptoms

Diabetic Ketoacidosis - Symptoms

A A A Diabetic Ketoacidosis Diabetic ketoacidosis (DKA) results from dehydration during a state of relative insulin deficiency, associated with high blood levels of sugar level and organic acids called ketones. Diabetic ketoacidosis is associated with significant disturbances of the body's chemistry, which resolve with proper therapy. Diabetic ketoacidosis usually occurs in people with type 1 (juvenile) diabetes mellitus (T1DM), but diabetic ketoacidosis can develop in any person with diabetes. Since type 1 diabetes typically starts before age 25 years, diabetic ketoacidosis is most common in this age group, but it may occur at any age. Males and females are equally affected. Diabetic ketoacidosis occurs when a person with diabetes becomes dehydrated. As the body produces a stress response, hormones (unopposed by insulin due to the insulin deficiency) begin to break down muscle, fat, and liver cells into glucose (sugar) and fatty acids for use as fuel. These hormones include glucagon, growth hormone, and adrenaline. These fatty acids are converted to ketones by a process called oxidation. The body consumes its own muscle, fat, and liver cells for fuel. In diabetic ketoacidosis, the body shifts from its normal fed metabolism (using carbohydrates for fuel) to a fasting state (using fat for fuel). The resulting increase in blood sugar occurs, because insulin is unavailable to transport sugar into cells for future use. As blood sugar levels rise, the kidneys cannot retain the extra sugar, which is dumped into the urine, thereby increasing urination and causing dehydration. Commonly, about 10% of total body fluids are lost as the patient slips into diabetic ketoacidosis. Significant loss of potassium and other salts in the excessive urination is also common. The most common Continue reading >>

4.1. Diabetic Ketoacidosis (DKA) Diabetic ketoacidosis results from lack of insulin and it is considered a medical emergency as it has a mortality rate of approximately 5 percent, mostly because of late recognition and frequently suboptimal management. Diabetic ketoacidosis can be the first manifestation of type 1 diabetes in a previously undiagnosed patient or can occur in a patient with type 1 diabetes when insulin requirements rise during medical stress. Noncompliance with insulin administration is another common cause of DKA. Although DKA is much more common in type 1 diabetes, it can also occur in patients with type 2 diabetes who have a predominant insulin secretory defect under severe medical stress. 4.1.1. Pathophysiology Diabetes is often referred to as "starvation in the midst of plenty" and the progression of events that results from acute insulin deficiency holds this concept to be valid. Insulin deficiency leads to impaired peripheral glucose uptake. In the presence of inadequate insulin, energy stores in fat and muscle are rapidly broken down into fatty acids and amino acids, which are then transported to the liver for conversion to glucose and ketones (beta-hydroxybutyrate and acetoacetate). Counter-regulatory hormones such as glucagon, catecholamines, cortisol and growth hormone rise in an attempt to correct the perceived low glucose levels, further contributing to hyperglycemia and ketonemia. The combination of increased production of glucose and ketones with decreased utilization (due to insulin deficiency) results in high levels of these substances. Hyperglycemia causes osmotic diuresis with an ensuing reduction of intravascular volume, which in turn causes an impairment of renal blood flow and an inability to excrete glucose which worsens the hypergl Continue reading >>

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 >>

Diabetic Ketoacidosis In Dogs

Diabetic Ketoacidosis In Dogs

My dog is diabetic. He has been doing pretty well overall, but recently he became really ill. He stopped eating well, started drinking lots of water, and got really weak. His veterinarian said that he had a condition called “ketoacidosis,” and he had to spend several days in the hospital. I’m not sure I understand this disorder. Diabetic ketoacidosis is a medical emergency that occurs when there is not enough insulin in the body to control blood sugar (glucose) levels. The body can’t use glucose properly without insulin, so blood glucose levels get very high, and the body creates ketone bodies as an emergency fuel source. When these are broken down, it creates byproducts that cause the body’s acid/base balance to shift, and the body becomes more acidic (acidosis), and it can’t maintain appropriate fluid balance. The electrolyte (mineral) balance becomes disrupted which can lead to abnormal heart rhythms and abnormal muscle function. If left untreated, diabetic ketoacidosis is fatal. How could this disorder have happened? If a diabetic dog undergoes a stress event of some kind, the body secretes stress hormones that interfere with appropriate insulin activity. Examples of stress events that can lead to diabetic ketoacidosis include infection, inflammation, and heart disease. What are the signs of diabetic ketoacidosis? The signs of diabetic ketoacidosis include: Excessive thirst/drinking Increased urination Lethargy Weakness Vomiting Increased respiratory rate Decreased appetite Weight loss (unplanned) with muscle wasting Dehydration Unkempt haircoat These same clinical signs can occur with other medical conditions, so it is important for your veterinarian to perform appropriate diagnostic tests to determine if diabetic ketoacidosis in truly the issue at hand Continue reading >>

Rare Complications Of Pediatric Diabetic Ketoacidosis

Rare Complications Of Pediatric Diabetic Ketoacidosis

Go to: CEREBRAL EDEMA Many children who present with DKA have some degree of altered mental status. Typically the altered status is due to acidosis or hyperosmolarity, although some studies show that subclinical cerebral edema occurs in the majority of patients in DKA[9,10]. Approximately 0.5%-1% of children in DKA develop frank cerebral edema[11-13]. Morbidity related to cerebral edema is approximately 13%-35% and mortality 24%-28%[12,14]. Risk factors for the development of cerebral edema during DKA include new onset T1DM, low bicarbonate, low partial pressure of CO2, and high BUN[13,15]. Conventional thinking attributes the mechanism of injury in cerebral edema to swelling from an influx of fluid into the brain[15-17]. This influx is thought to be due to the rapidly declining serum osmolarity caused by overly aggressive fluid resuscitation; however, data reveals the only treatment-related risk factor to be administration of bicarbonate[15]. The association between high fluid infusion rates and development of cerebral edema trends toward, but does not reach, statistical significance[13]. Radiographic confirmation of cerebral edema in patients with DKA prior to initiation of fluid therapy further discredits the association[13,15]. Also, many children have normal brain imaging at the onset of clinical cerebral edema and do not develop radiographic signs of edema until hours or days later, suggesting that edema is a consequence rather than the cause of injury[11]. A more plausible hypothesis is that cerebral edema is caused by cerebral hypoperfusion, which leads to cytotoxic edema (cell swelling and death) at presentation followed by vasogenic edema (breakdown of the blood brain barrier leading to capillary leakage) during treatment[9]. There is supporting evidence for t Continue reading >>

Type 1 Diabetes Complications

Type 1 Diabetes Complications

Type 1 diabetes is complicated—and if you don’t manage it properly, there are complications, both short-term and long-term. “If you don’t manage it properly” is an important if statement: by carefully managing your blood glucose levels, you can stave off or prevent the short- and long-term complications. And if you’ve already developed diabetes complications, controlling your blood glucose levels can help you manage the symptoms and prevent further damage. Diabetes complications are all related to poor blood glucose control, so you must work carefully with your doctor and diabetes team to correctly manage your blood sugar (or your child’s blood sugar). Short-term Diabetes Complications Hypoglycemia: Hypoglycemia is low blood glucose (blood sugar). It develops when there’s too much insulin—meaning that you’ve taken (or given your child) too much insulin or that you haven’t properly planned insulin around meals or exercise. Other possible causes of hypoglycemia include certain medications (aspirin, for example, lowers the blood glucose level if you take a dose of more than 81mg) and alcohol (alcohol keeps the liver from releasing glucose). There are three levels of hypoglycemia, depending on how low the blood glucose level has dropped: mild, moderate, and severe. If you treat hypoglycemia when it’s in the mild or moderate stages, then you can prevent far more serious problems; severe hypoglycemia can cause a coma and even death (although very, very rarely). The signs and symptoms of low blood glucose are usually easy to recognize: Rapid heartbeat Sweating Paleness of skin Anxiety Numbness in fingers, toes, and lips Sleepiness Confusion Headache Slurred speech For more information about hypoglycemia and how to treat it, please read our article on hy Continue reading >>

Diabetic Ketoacidosis (dka)

Diabetic Ketoacidosis (dka)

Tweet Diabetic ketoacidosis (DKA) is a dangerous complication faced by people with diabetes which happens when the body starts running out of insulin. DKA is most commonly associated with type 1 diabetes, however, people with type 2 diabetes that produce very little of their own insulin may also be affected. Ketoacidosis is a serious short term complication which can result in coma or even death if it is not treated quickly. Read about Diabetes and Ketones What is diabetic ketoacidosis? DKA occurs when the body has insufficient insulin to allow enough glucose to enter cells, and so the body switches to burning fatty acids and producing acidic ketone bodies. A high level of ketone bodies in the blood can cause particularly severe illness. Symptoms of DKA Diabetic ketoacidosis may itself be the symptom of undiagnosed type 1 diabetes. Typical symptoms of diabetic ketoacidosis include: Vomiting Dehydration An unusual smell on the breath –sometimes compared to the smell of pear drops Deep laboured breathing (called kussmaul breathing) or hyperventilation Rapid heartbeat Confusion and disorientation Symptoms of diabetic ketoacidosis usually evolve over a 24 hour period if blood glucose levels become and remain too high (hyperglycemia). Causes and risk factors for diabetic ketoacidosis As noted above, DKA is caused by the body having too little insulin to allow cells to take in glucose for energy. This may happen for a number of reasons including: Having blood glucose levels consistently over 15 mmol/l Missing insulin injections If a fault has developed in your insulin pen or insulin pump As a result of illness or infections High or prolonged levels of stress Excessive alcohol consumption DKA may also occur prior to a diagnosis of type 1 diabetes. Ketoacidosis can occasional 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 >>

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 Explained

Diabetic Ketoacidosis Explained

Twitter Summary: DKA - a major complication of #diabetes – we describe what it is, symptoms, who’s at risk, prevention + treatment! One of the most notorious complications of diabetes is diabetic ketoacidosis, or DKA. First described in the late 19th century, DKA represented something close to the ultimate diabetes emergency: In just 24 hours, people can experience an onset of severe symptoms, all leading to coma or death. But DKA also represents one of the great triumphs of the revolution in diabetes care over the last century. Before the discovery of insulin in 1920, DKA was almost invariably fatal, but the mortality rate for DKA dropped to below 30 percent within 10 years, and now fewer than 1 percent of those who develop DKA die from it, provided they get adequate care in time. Don’t skip over that last phrase, because it’s crucial: DKA is very treatable, but only as long as it’s diagnosed promptly and patients understand the risk. Table of Contents: What are the symptoms of DKA? Does DKA occur in both type 1 and type 2 diabetes? What Can Patients do to Prevent DKA? What is DKA? Insulin plays a critical role in the body’s functioning: it tells cells to absorb the glucose in the blood so that the body can use it for energy. When there’s no insulin to take that glucose out of the blood, high blood sugar (hyperglycemia) results. The body will also start burning fatty acids for energy, since it can’t get that energy from glucose. To make fatty acids usable for energy, the liver has to convert them into compounds known as ketones, and these ketones make the blood more acidic. DKA results when acid levels get too high in the blood. There are other issues too, as DKA also often leads to the overproduction and release of hormones like glucagon and adrenaline Continue reading >>
