Diabetes With Ketone Bodies In Dogs
Studies show that female dogs (particularly non-spayed) are more prone to DKA, as are older canines. Diabetic ketoacidosis is best classified through the presence of ketones that exist in the liver, which are directly correlated to the lack of insulin being produced in the body. This is a very serious complication, requiring immediate veterinary intervention. Although a number of dogs can be affected mildly, the majority are very ill. Some dogs will not recover despite treatment, and concurrent disease has been documented in 70% of canines diagnosed with DKA. Diabetes with ketone bodies is also described in veterinary terms as diabetic ketoacidosis or DKA. It is a severe complication of diabetes mellitus. Excess ketone bodies result in acidosis and electrolyte abnormalities, which can lead to a crisis situation for your dog. If left in an untreated state, this condition can and will be fatal. Some dogs who are suffering from diabetic ketoacidosis may present as systemically well. Others will show severe illness. Symptoms may be seen as listed below: Change in appetite (either increase or decrease) Increased thirst Frequent urination Vomiting Abdominal pain Mental dullness Coughing Fatigue or weakness Weight loss Sometimes sweet smelling breath is evident Slow, deep respiration. There may also be other symptoms present that accompany diseases that can trigger DKA, such as hypothyroidism or Cushing’s disease. While some dogs may live fairly normal lives with this condition before it is diagnosed, most canines who become sick will do so within a week of the start of the illness. There are four influences that can bring on DKA: Fasting Insulin deficiency as a result of unknown and untreated diabetes, or insulin deficiency due to an underlying disease that in turn exacerba Continue reading >>
What is Diabetic Ketoacidosis Diabetic ketoacidosis (DKA) is the hallmark of type 1 (insulin-dependent) diabetes mellitus. DKA is an emergency condition caused by a disturbance in your body’s metabolism. Extremely high blood glucose levels, along with a severe lack of insulin, result in the breakdown of body fat for energy and an accumulation of ketones in the blood and urine. Statistics on Diabetic Ketoacidosis Diabetic ketoacidosis can occur in between 16%-80% of children presenting with newly diagnosed diabetes. It remains the most common cause of death for young type 1 diabetes sufferers. Before the discovery of insulin, mortality rates were up to 100%. Today, the mortality has fallen to around 2% due to early identification and treatment. Death is usually caused by cerebral oedema (swelling of the brain). DKA is most common in type 1 diabetes sufferers but may also occur in those with type 2 diabetes mellitus. However, the latter group usually has at least some functioning insulin so suffer from another disorder called hyperosmolar non-ketotic coma (HONK). DKA tends to occur in individuals younger than 19 years, the more brittle of type 1 diabetic patients. However, DKA can affect diabetic patients of any age or sex. Risk Factors for Diabetic Ketoacidosis People with diabetes lack sufficient insulin, a hormone the body uses to metabolise glucose (a simple sugar) for energy. Therefore in diabetic patients glucose is not available as a fuel, so the body turns to fat stores for energy. However when fats are broken down they produce byproducts called ketones which build up in the blood and can be damaging to the body. In particular, accumulated ketones can “spill” over into the urine and make the blood become more acidic than body tissues (ketoacidosis). Blood gl Continue reading >>
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.

How Does Cancer Cause Death?
By proliferation and activation of secretion by a cell type that deranges overall metabolism or some particular signaling function. Example: production of calcitonin by a thyroid tumor, paralyzing the heart. Many cancers lead to cachexia that way. By producing tumors that impinge mechanically on normal tissues and impair their function. Example: lymphomas causing strokes embolically. By depriving nearby functional tissues of energy or substrate, disrupting essential functions. Example: liver cancers depriving the blood of albumin and/or globulins. By negative feedback to counteract the proliferation of related normal tissues whose normal function is proliferative, as in the immune system or digestive tract. Short answer: A cellular mass will experience uncontrolled growth, depriving the organs around it of vital resources until they begin to shut down and die. Long answer: “Cancer” is not really a single disease. It manifests itself in many ways, in may parts of the body. The one thing they all have in common is the short answer above. That being said, the specifics of how a cancer kills are unique to that particular form of cancer. Cancer comes in a wide variety of forms, but they all have the tendency to damage the organs they spread to. So I imagine that organ failures can be caused by cancers and that it's the organ failures that frequently kill. There is also the starvation aspect of cancers suppressing the appetite and tumor cells taking up all the nutrients for themselves at the expense of your normal cells. This may or may not be fatal in and of itself, but it certainly doesn't help deal with the rest of complications cancers bring. Continue reading >>
How Does Diabetic Ketoacidosis Cause Vomiting?
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. 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 to function as well. A higher level of ketones also affects levels of sugar and electrolytes in the body. As ketones accumulate in the blood, more ketones will be passed in the urine, taking sodium and potassium salts out with them. Over time, levels of sodium and potassium salts in the body become depleted, which can cause nausea and vomiting. The result is a vicious cycle. The most important prevention strategies are to monitor blood glucose levels routinely, keep blood glucose levels controlled (e.g., Continue reading >>
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 >>
What Is Diabetic Ketoacidosis?
Diabetic ketoacidosis, or DKA, is a serious health problem that can happen to a person with diabetes. It happens when chemicals called ketones build up in the blood. Normally, the cells of your body take in and use glucose as a source of energy. Glucose moves through the body in the bloodstream. Insulin is a hormone that helps your cells take in the glucose from the blood. If you have diabetes, your cells can’t take in and use this glucose in a normal way. This may be because your body doesn’t make enough insulin. Or it may be because your cells don’t respond to it normally. As a result, glucose builds up in your bloodstream and doesn’t reach your cells. Without glucose to use, the cells in your body burn fat instead of glucose for energy. When cells burn fat, they make ketones. High levels of ketones can poison the body. High levels of glucose can also build up in your blood and cause other symptoms. Ketoacidosis also changes the amount of other substances in your blood. These include electrolytes, such as sodium, potassium, and bicarbonate. This can lead to other problems. Ketoacidosis happens most often in a person with type 1 diabetes. This is a condition where the body does not make enough insulin. In rare cases, ketoacidosis can happen in a person with type 2 diabetes. It can happen when they are under stress, like when they are sick, or when they have taken certain medicines that change how their bodies handle glucose. Diabetic ketoacidosis is pretty common. It is more common in younger people. Women have it more often than men do. What causes diabetic ketoacidosis? High levels of ketones and glucose in your blood can cause ketoacidosis. This might happen if you: Don’t know you have diabetes, and your body is breaking down too much fat Know you have dia Continue reading >>
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 >>
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 >>
5 Common Type 1 Diabetes Complications
3 0 Type 1 diabetes carries with it a much higher risk of developing some associated serious health problems. While in the past, getting diabetes-related health complications was almost a certainty, with modern blood glucose monitoring, control, and treatment, the risks have decreased significantly. Even a few decades ago, life expectancy for people with diabetes was regularly considered to be 10 years shorter than for people without the disorder. In 2012, however, a large-scale study found that life-expectancy was now only about 6 years less than average. For comparison, a lifetime of smoking will reduce life expectancy by 10 years. So what are the diabetes complications that you need to be looking out for? Largely, they fall into either cardiovascular or neuropathic categories. To make diabetes complications even more complicated, they tend to affect people of different sexes and different ethnicities differently. One more wild card is that recent studies have found that some people with Type 1 diabetes actually never develop most of the complications associated with diabetes. The good news is that with proper blood glucose control and a healthy lifestyle, the risks for developing Type 1 diabetes complications are drastically reduced. Some studies have actually found that careful monitoring and management can reduce the chances of developing any of these by as much as 50%. Still, everyone with Type 1 diabetes should keep a careful eye out for the five most common diabetes complications. Diabetic Ketoacidosis Diabetic Ketoacidosis (or DKA), is a condition caused by severe hyperglycemia (high blood sugar) which causes rapid fat breakdown in the body. As the fat breaks down, they release fatty acids which are then converted into chemicals called ketones, which are highly Continue reading >>

High Blood Sugars (ketoacidosis)
Ketoacidosis And Hyperglycemic Hyperosmolar Syndrome Severe high blood sugars, ketosis (the presence of ketones prior to acidification of the blood), and ketoacidosis (DKA) are serious and potentially life-threatening medical problems which can occur in diabetes. High blood sugars become life-threatening in Type 1 or long-term Type 2 diabetes only when that person does not receive enough insulin from injections or an insulin pump. This can be caused by skipping insulin or not receiving enough insulin when large amounts are required due to an infection or other major stress. Ketoacidosis surprisingly occurs almost as often in Type 2 diabetes as it does in Type 1. However, people with Type 2 diabetes also encounter another dangerous condition called hyperglycemic hyperosmolar syndrome, which is roughly translated as thick blood due to very high blood sugars. Here, coma and death can occur simply because the blood sugar is so high. The blood will have ketones at higher levels but does not become acidotic. HHS usually occurs with blood sugar readings above 700 mg/dl (40 mmol) as the brain and other functions begin to shut down. When insulin levels are low, the body cannot use glucose present at high levels in the blood. The body then starts burning excessive amounts of fat which causes the blood to become acidic as excess ketone byproducts are produced. Even though the blood pH which measures acidity only drops from its normal level of 7.4 down to 7.1 or 7.0, this small drop is enough to inactivate enzymes that depend on a precise acid-base balance to operate. High blood sugars and ketoacidosis can be triggered by: not taking insulin severe infection severe illness bad insulin In Type 1 diabetes, ketoacidosis often occurs under the duress of an infection, and is also freque Continue reading >>
Diabetic Ketoacidosis In Pregnancy
Diabetic ketoacidosis is a serious metabolic complication of diabetes with high mortality if undetected. Its occurrence in pregnancy compromises both the fetus and the mother profoundly. Although predictably more common in patients with type 1 diabetes, it has been recognised in those with type 2 diabetes as well as gestational diabetes, especially with the use of corticosteroids for fetal lung maturity and β2-agonists for tocolysis.1–3 Diabetic ketoacidosis usually occurs in the second and third trimesters because of increased insulin resistance, and is also seen in newly presenting type 1 diabetes patients. With increasing practice of antepartum diabetes screening and the availability of early and frequent prenatal care/surveillance, the incidence and outcomes of diabetic ketoacidosis in pregnancy have vastly improved. However, it still remains a major clinical problem in pregnancy since it tends to occur at lower blood glucose levels and more rapidly than in non-pregnant patients often causing delay in the diagnosis. The purpose of this article is to illustrate a typical patient who may present with diabetic ketoacidosis in pregnancy and review the literature on this relatively uncommon condition and provide an insight into the pathophysiology and management. MAGNITUDE OF THE PROBLEM In non-pregnant patients with type 1 diabetes, the incidence of diabetic ketoacidosis is about 1–5 episodes per 100 per year with mortality averaging 5%–10%.4 The incidence rates of diabetic ketoacidosis in pregnancy and the corresponding fetal mortality rates from different retrospective studies5–8 are summarised in the table 1. As is evident from the table, both the incidence and rates of fetal loss in pregnancies have fallen in recent times compared with those before. In 1963 Continue reading >>
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 >>
Mother Of 22-year-old Who Died From Diabetic Ketoacidosis Speaks Out
In the aftermath of her son's tragic death, Lyndall Hauver urges caregivers: People with type 1 diabetes who develop flu-like symptoms should head straight to the hospital. Will Hauver was feeling under the weather with aches, an upset stomach, and fever, but still had enough energy for varsity lacrosse practice at Rollins College in Florida the last day of January in 2015. It appeared he got the flu that already struck others on campus. The next day, a Sunday, the 22-year-old felt a bit better and visited his fraternity, rounding up some freshman pledges to clean his house. He went to bed early to rest up for an upcoming lacrosse trip. Monday morning, Will's roommate found him on the floor, passed out. By that afternoon, he had died. Will, who had type 1 diabetes, died from diabetic ketoacidosis (or DKA)1 a serious, acute complication of diabetes that results from too little insulin and can be brought on by the flu.2 When a person develops DKA it's the result of dangerously high levels of blood acids in the body called ketones. Ketones alter the chemical balance of blood in the body.3 After Will's death, his grief-stricken mom, Lyndall Hauver, of Towson, Maryland, decided to share Will's story in the hope that others will learn from her family's tragic loss. "As soon as you get a fever or have a sign of the flu or a stomach virus go to the hospital," Lyndall says. "It causes your blood sugar to go crazy, to go up and down and that wreaks havoc on your fluids and heart and everything else." "You have to be vigilant," she continues. "It's easy to get complacent when things are going well." She adds: "This was a fluke occurrence, bad luck, and I can't change it. It breaks my heart every minute." The Longest Hour Days before Will's death, the parents of some of Will's team Continue reading >>
Diabetic Ketoacidosis: A Silent Death.
Abstract Diabetic ketoacidosis (DKA) results from severe insulin deficiency and can be diagnosed at autopsy despite no known history of the disease. Diabetic ketoacidosis may be the initial manifestation of type 1 diabetes or may result from increased insulin requirement in type 1 diabetic patients. The purpose of this study was to determine the percentage of DKA death investigated by the Office of Chief Medical Examiner that was not associated with a known history of diabetes.Cases investigated by the Office of Chief Medical Examiner during a 6-year period whose cause of death was DKA were identified using a centralized database. To determine the percentage with known history of diabetes, investigation reports were reviewed for any documentation of this history. The toxicology reports of all DKA deaths were reviewed together with histologic slides, if available, for possible microscopic changes. Concentrations of vitreous glucose, vitreous acetone, and blood acetone were used to diagnose DKA in these autopsied cases.Nearly a third of all death from DKA (32 of 92 during a 6-year period) occurred in individuals who had no known history of diabetes, emphasizing the importance of regular physicals that include a check of glucose concentration, and especially if any warning signs are present. In a case of sudden death, it is recommended that the volatile toxicology analysis at a medical examiner's office should include tests for acetone concentration, which when elevated, together with an elevated vitreous glucose, indicates DKA.
