The serum phosphate level in DKA may be elevated despite total-body phosphate depletion. There are multiple risks associated with intubation in patients with DKA. The lack of insulin and corresponding elevation of glucagon leads to increased release of glucose by the liver a process that is normally suppressed by insulin from glycogen via glycogenolysis and also through gluconeogenesis. Diabetic ketoacidosis explained

Diabetic ketoacidosis explained -

Acetone derived from the metabolism of acetoacetic acid accumulates in serum and is slowly disposed of by respiration. Hyperglycemia due to insulin deficiency causes an osmotic diuresis that leads to marked urinary losses of water and electrolytes.

Urinary excretion of ketones obligates additional losses of sodium and potassium. Serum sodium may fall due to natriuresis or rise due to excretion of large volumes of free water. Potassium is also lost in large quantities.

Despite a significant total body deficit of potassium, initial serum potassium is typically normal or elevated because of the extracellular migration of potassium in response to acidosis.

Potassium levels generally fall further during treatment as insulin therapy drives potassium into cells. The most common read more may develop. Symptoms and signs of diabetic ketoacidosis include symptoms of hyperglycemia Symptoms and Signs Diabetes mellitus is impaired insulin secretion and variable degrees of peripheral insulin resistance leading to hyperglycemia.

Patients may be hypotensive and tachycardic due to dehydration and acidosis; they may breathe rapidly and deeply to compensate for acidemia Kussmaul respirations. They may also have fruity breath due to exhaled acetone.

Fever is not a sign of DKA itself and, if present, signifies underlying infection. In the absence of timely treatment, DKA progresses to coma and death. Headache and fluctuating level of consciousness herald this complication in some patients, but respiratory arrest is the initial manifestation in others.

The cause is not well understood but may be related to too-rapid reductions in serum osmolality or to brain ischemia. It is most likely to occur in children 5 years when DKA is the initial manifestation of diabetes mellitus Diabetes Mellitus DM Diabetes mellitus is impaired insulin secretion and variable degrees of peripheral insulin resistance leading to hyperglycemia.

Children with the highest BUN blood urea nitrogen levels and lowest PaCO2 at presentation appear to be at greatest risk. Delays in correction of hyponatremia and the use of bicarbonate during DKA treatment are additional risk factors.

In patients suspected of having diabetic ketoacidosis, serum electrolytes, blood urea nitrogen BUN and creatinine, glucose, ketones, and osmolarity should be measured. Urine should be tested for ketones. Patients who appear significantly ill and those with positive ketones should have arterial blood gas measurement.

DKA is diagnosed by an arterial pH 7. Guidelines differ on specific levels of hyperglycemia to be included in the diagnostic criteria for DKA.

Hyperglycemia causes an osmotic diuresis with A presumptive diagnosis may be made when urine glucose and ketones are positive on urinalysis. Urine test strips and some assays for serum ketones may underestimate the degree of ketosis because they detect acetoacetic acid and not beta-hydroxybutyric acid, which is usually the predominant ketoacid.

Blood beta-hydroxybutyrate can be measured, or treatment can be initiated based on clinical suspicion and the presence of anion gap acidosis if serum or urine ketones are low.

Symptoms and signs of a triggering illness should be pursued with appropriate studies eg, cultures, imaging studies. Adults should have an ECG to screen for acute myocardial infarction and to help determine the significance of abnormalities in serum potassium.

Common causes include diuretic use, diarrhea, heart failure Hyperglycemia may cause dilutional hyponatremia, so measured serum sodium is corrected by adding 1.

The most urgent goals for treating diabetic ketoacidosis are rapid intravascular volume repletion, correction of hyperglycemia and acidosis, and prevention of hypokalemia 1, 2 Treatment references Diabetic ketoacidosis DKA is an acute metabolic complication of diabetes characterized by hyperglycemia, hyperketonemia, and metabolic acidosis.

Identification of precipitating factors is also important. Treatment should occur in intensive care settings because clinical and laboratory assessments are initially needed every hour or every other hour with appropriate adjustments in treatment. Intravascular volume should be restored rapidly to raise blood pressure and ensure glomerular perfusion; once intravascular volume is restored, remaining total body water deficits are corrected more slowly, typically over about 24 hours.

Initial volume repletion in adults is typically achieved with rapid IV infusion of 1 to 1. Additional boluses or a faster rate of infusion may be needed to raise the blood pressure. It occurs in about 1 out of children with DKA and more rarely occurs in adults. DKA most frequently occurs in those who know that they have diabetes, but it may also be the first presentation in someone who has not previously been known to be diabetic.

There is often a particular underlying problem that has led to the DKA episode; this may be intercurrent illness pneumonia , influenza , gastroenteritis , a urinary tract infection , pregnancy , inadequate insulin administration e.

defective insulin pen device , myocardial infarction heart attack , stroke or the use of cocaine. Young people with recurrent episodes of DKA may have an underlying eating disorder , or may be using insufficient insulin for fear that it will cause weight gain.

Diabetic ketoacidosis may occur in those previously known to have diabetes mellitus type 2 or in those who on further investigations turn out to have features of type 2 diabetes e. obesity , strong family history ; this is more common in African, African-American and Hispanic people.

Their condition is then labeled "ketosis-prone type 2 diabetes". Drugs in the gliflozin class SGLT2 inhibitors , which are generally used for type 2 diabetes, have been associated with cases of diabetic ketoacidosis where the blood sugars may not be significantly elevated "euglycemic DKA".

Furthermore, it can be triggered by severe acute illness, dehydration, extensive exercise, surgery, low-carbohydrate diets, or excessive alcohol intake. Specifically, they should not be used if someone is also using a low carbohydrate or ketogenic diet. Diabetic ketoacidosis arises because of a lack of insulin in the body.

The lack of insulin and corresponding elevation of glucagon leads to increased release of glucose by the liver a process that is normally suppressed by insulin from glycogen via glycogenolysis and also through gluconeogenesis.

High glucose levels spill over into the urine, taking water and solutes such as sodium and potassium along with it in a process known as osmotic diuresis.

The absence of insulin also leads to the release of free fatty acids from adipose tissue lipolysis , which the liver converts into acetyl CoA through a process called beta oxidation.

Acetyl CoA is metabolised into ketone bodies under severe states of energy deficiency, like starvation, through a process called ketogenesis , whose final products are aceto-acetate and β-Hydroxybutyrate.

These ketone bodies can serve as an energy source in the absence of insulin-mediated glucose delivery, and is a protective mechanism in case of starvation.

The ketone bodies, however, have a low pKa and therefore turn the blood acidic metabolic acidosis. The body initially buffers the change with the bicarbonate buffering system , but this system is quickly overwhelmed and other mechanisms must work to compensate for the acidosis.

This hyperventilation, in its extreme form, may be observed as Kussmaul respiration. In various situations such as infection, insulin demands rise but are not matched by the failing pancreas.

Blood sugars rise, dehydration ensues, and resistance to the normal effects of insulin increases further by way of a vicious circle. Glucose levels usually exceed DKA is common in type 1 diabetes as this form of diabetes is associated with an absolute lack of insulin production by the islets of Langerhans.

In type 2 diabetes, insulin production is present but is insufficient to meet the body's requirements as a result of end-organ insulin resistance. Usually, these amounts of insulin are sufficient to suppress ketogenesis.

If DKA occurs in someone with type 2 diabetes, their condition is called "ketosis-prone type 2 diabetes". The clinical state of DKA is associated, in addition to the above, with the release of various counterregulatory hormones such as glucagon and adrenaline as well as cytokines , the latter of which leads to increased markers of inflammation , even in the absence of infection.

Cerebral edema, which is the most dangerous DKA complication, is probably the result of a number of factors. Some authorities suggest that it is the result of overvigorous fluid replacement, but the complication may develop before treatment has been commenced. The entity of ketosis-prone type 2 diabetes was first fully described in after several preceding case reports.

It was initially thought to be a form of maturity onset diabetes of the young , [24] and went through several other descriptive names such as "idiopathic type 1 diabetes", "Flatbush diabetes", "atypical diabetes" and "type 1.

It has been reported predominantly in non-white ethnicity in African—Americans, Hispanics, Black Africans and Black Caribbeans. Diabetic ketoacidosis may be diagnosed when the combination of hyperglycemia high blood sugars , ketones in the blood or on urinalysis and acidosis are demonstrated.

A pH measurement is performed to detect acidosis. Blood from a vein is adequate, as there is little difference between the arterial and the venous pH; arterial samples are only required if there are concerns about oxygen levels.

When compared with urine acetoacetate testing, capillary blood β-hydroxybutyrate determination can reduce the need for admission, shorten the duration of hospital admission and potentially reduce the costs of hospital care. In addition to the above, blood samples are usually taken to measure urea and creatinine measures of kidney function , which may be impaired in DKA as a result of dehydration and electrolytes.

Furthermore, markers of infection complete blood count , C-reactive protein and acute pancreatitis amylase and lipase may be measured. Given the need to exclude infection, chest radiography and urinalysis are usually performed.

If cerebral edema is suspected because of confusion, recurrent vomiting or other symptoms, computed tomography may be performed to assess its severity and to exclude other causes such as stroke. Diabetic ketoacidosis is distinguished from other diabetic emergencies by the presence of large amounts of ketones in blood and urine, and marked metabolic acidosis.

There is a degree of overlap between DKA and HHS, as in DKA the osmolarity may also be increased. Ketoacidosis is not always the result of diabetes.

It may also result from alcohol excess and from starvation ; in both states the glucose level is normal or low. Metabolic acidosis may occur in people with diabetes for other reasons, such as poisoning with ethylene glycol or paraldehyde.

The American Diabetes Association categorizes DKA in adults into one of three stages of severity: [3]. A statement by the European Society for Paediatric Endocrinology and the Lawson Wilkins Pediatric Endocrine Society for children uses slightly different cutoffs, where mild DKA is defined by pH 7.

Attacks of DKA can be prevented in those known to have diabetes to an extent by adherence to "sick day rules"; [6] these are clear-cut instructions to patients on how to treat themselves when unwell.

Instructions include advice on how much extra insulin to take when sugar levels appear uncontrolled, an easily digestible diet rich in salt and carbohydrates, means to suppress fever and treat infection, and recommendations on when to call for medical help.

People with diabetes can monitor their own ketone levels when unwell and seek help if they are elevated.

The main aim in the treatment of diabetic ketoacidosis is to replace the lost fluids and electrolytes while suppressing the high blood sugars and ketone production with insulin.

Admission to an intensive care unit ICU or similar high-dependency area or ward for close observation may be necessary.

The amount of fluid replaced depends on the estimated degree of dehydration. Normal saline 0. A special but unusual consideration is cardiogenic shock , where the blood pressure is decreased not due to dehydration but due to the inability of the heart to pump blood through the blood vessels.

This situation requires ICU admission, monitoring of the central venous pressure which requires the insertion of a central venous catheter in a large upper body vein , and the administration of medication that increases the heart pumping action and blood pressure.

The liver processes the fat into a fuel called ketones, which causes the blood to become acidic. The fat is broken down by the liver into a fuel called ketones.

Ketones are normally produced by the liver when the body breaks down fat after it has been a long time since your last meal. These ketones are normally used by the muscles and the heart.

When ketones are produced too quickly and build up in the blood, they can be toxic by making the blood acidic. This condition is known as 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 the stress of surgery can lead to DKA in people with type 1 diabetes.

People with type 2 diabetes can also develop DKA, but it is much less common and less severe. It is usually triggered by prolonged uncontrolled blood sugar, missing doses of medicines, or a severe illness or infection.

Ketone testing may be used in type 1 diabetes to screen for early ketoacidosis. The ketone test is usually done using a urine sample or a blood sample. The goal of treatment is to correct the high blood sugar level with insulin.

Another goal is to replace fluids and bodily chemicals lost through urination, loss of appetite, and vomiting if you have these symptoms. If you have diabetes, it is likely your health care provider told you how to spot the warning signs of DKA.

If you think you have DKA, test for ketones using urine strips. Some glucose meters can also measure blood ketones. If ketones are present, call your provider right away. Do not delay.

If you spot any of these symptoms it is a sign that you need to get some medical help quickly. If your blood sugar is high, check for ketones. You can check your blood or your urine for ketones. A blood test will show your ketone levels in real time but a urine test will show what they were a few hours ago.

If you have type 1 diabetes you should get either a blood ketone monitor or urine testing strips for free from the NHS. If you have high ketone levels in your blood and suspect DKA, you should get medical help straight away.

DKA is serious and must be treated in hospital quickly. Left untreated, it could lead to a life-threatening situation. You'll also be closely monitored to make sure there are no serious problems with your brain, kidneys or lungs.

You'll be able to leave hospital when you're well enough to eat and drink and tests show a safe level of ketones in your body. You can help avoid DKA by monitoring your blood sugar levels regularly and altering your insulin dose in response to your blood sugar levels and what you eat.

Your blood sugar levels could be higher than normal when you are unwell. You may need to drink more fluids, take more insulin and check your blood sugars more than you would usually.

The amount of extra insulin needed will vary from person to person. Your diabetes team will help you to work out the correct dose for you or your child. For some people, becoming suddenly very ill with DKA can be what leads them to finding out they have type 1 diabetes in the first place.

But if you suspect you or your child has DKA it is important to get medical help straight away.
