Diabetic ketoacidosis overview -

This is the best way to know when your blood sugar is high so you can treat it early. Watching for symptoms is not as helpful. This is because you may not have symptoms until your blood sugar is very high.

Or you may not notice them. Teach others at work and at home how to check your blood sugar. Make sure that someone else knows how do it in case you can't. Wear or carry medical identification at all times.

This is very important in case you are too sick or injured to speak for yourself. Talk to your doctor about when you can start to exercise again. Eat regular meals that spread your calories and carbohydrate throughout the day.

This will help keep your blood sugar steady. When you are sick: Take your insulin and diabetes medicines. This is important even if you are vomiting and having trouble eating or drinking. Your blood sugar may go up because you are sick. If you are eating less than normal, you may need to change your dose of insulin.

Talk with your doctor about a plan when you are well. Then you will know what to do when you are sick.

Drink extra fluids to prevent dehydration. These include water, broth, and sugar-free drinks. If you don't drink enough, the insulin from your shot may not get into your blood.

So your blood sugar may go up. Try to eat as you normally do, with a focus on healthy food choices. Check your blood sugar at least every 3 to 4 hours. Check it more often if it's rising fast. If your doctor has told you to take an extra insulin dose for high blood sugar levels for example, above If you're not sure how much to take, call your doctor or nurse advice line.

Check your temperature and pulse often. If your temperature goes up, call your doctor or nurse advice line. You may be getting worse. If you take insulin, check your urine or blood for ketones, especially when you have high blood sugar for example, above Call your doctor or nurse advice line if your ketone level is moderate or high.

Glycerol and alanine provide substrate for hepatic gluconeogenesis, which is stimulated by the excess of glucagon that accompanies insulin deficiency. Glucagon also stimulates mitochondrial conversion of free fatty acids into ketones. Insulin normally blocks ketogenesis by inhibiting the transport of free fatty acid derivatives into the mitochondrial matrix, but ketogenesis proceeds in the absence of insulin.

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. As acidosis is corrected, serum potassium drops.

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.

DKA is characterized by ketoacidosis and hyperglycemia, while HHS usually has more severe hyperglycemia but no ketoacidosis table 1. Each represents an extreme in the spectrum of hyperglycemia.
