What happens in DKA?

Diabetic ketoacidosis (DKA) is a life-threatening problem that affects people with diabetes. It occurs when the body starts breaking down fat at a rate that is much too fast. The liver processes the fat into a fuel called ketones, which causes the blood to become acidic.

What is DKA from diabetes?

Diabetic ketoacidosis (DKA) is a serious complication of diabetes that can be life-threatening. DKA is most common among people with type 1 diabetes. People with type 2 diabetes can also develop DKA. DKA develops when your body doesn’t have enough insulin to allow blood sugar into your cells for use as energy.

How is hyperkalemia treated in DKA?

Rapid hemodialysis along with intensive insulin therapy can improve hyperkalemia, while fluid infusions may worsen heart failure in patients with ketoacidosis who routinely require hemodialysis.

How does insulin help diabetes?

Sometimes, people with type 2 diabetes or gestational diabetes need insulin therapy if other treatments haven’t been able to keep blood glucose levels within the desired range. Insulin therapy helps prevent diabetes complications by keeping your blood sugar within your target range.

Can you have diabetic ketoacidosis without diabetes?

Very rarely, DKA can occur in people without diabetes. In this case, insulin levels fall enough to induce diabetic ketoacidosis, even though blood glucose levels are not elevated.

How is DKA diagnosed?

A diagnosis of diabetic ketoacidosis requires the patient’s plasma glucose concentration to be above 250 mg per dL (although it usually is much higher), the pH level to be less than 7.30, and the bicarbonate level to be 18 mEq per L or less.

Does DKA cause hypokalemia or hyperkalemia?

DKA is a well-known cause of hypokalemia caused by osmotic diuresis leading to a total body potassium deficiency of 3 to 6 mEq/kg. At presentation, potassium levels are typically “normal” due to the extracellular shift of potassium (K+) from insulin deficiency and acidosis.

How is hypokalemia treated in DKA?

Replacement of potassium in intravenous fluids is the standard of care in treatment of DKA to prevent the potential consequences of hypokalemia including cardiac arrhythmias and respiratory failure.

How is Hypernatremia treated in DKA?

Treating the DKA more aggressively than the hypernatremia itself, choosing a hypoosmolar fluid, and switching to D5-0.45% saline, when glucose has decreased, are some of the vital considerations for the management of hypernatremia in DKA.

What is insulin therapy?

Intensive insulin therapy is a treatment approach designed to keep your blood sugar levels closer to the levels of someone who doesn’t have diabetes. This treatment requires close monitoring of blood sugar levels and multiple doses of insulin.

How is insulin prescribed?

Human insulin is usually injected subcutaneously several times a day, and more than one type of insulin may be needed. Your doctor will tell you which type(s) of insulin to use, how much insulin to use, and how often to inject insulin. Follow these directions carefully.

When do you need insulin for diabetes?

Insulin for Short-Term Blood Sugar Control “The American Association of Clinical Endocrinologists recommends starting a person with type 2 diabetes on insulin if their A1C is above 9 percent and they have symptoms,” said Mazhari. Symptoms of type 2 diabetes include thirst, hunger, frequent urination, and weight loss.

Why do non diabetics get ketoacidosis?

Non-diabetic ketoacidosis is a rare condition which can be caused by starvation. Lack of glucose can force the body into ketogenesis causing a metabolic acidosis. As previously reported in the literature, ketoacidosis might, on rare occasions, be caused by a diet with low carbohydrate content.

What is the most common cause of ketoacidosis?

The most common causes of DKA are: missing an insulin injection or not injecting enough insulin. illness or infection. a clog in one’s insulin pump (for people who are using one)

Why would a patient with poorly managed diabetes be at risk of recurrent infections?

Why are people with diabetes more prone to infections? High blood sugar levels can weaken a person’s immune system defenses. People who have had diabetes for a long time may have peripheral nerve damage and reduced blood flow to their extremities, which increases the chance for infection.

When is DKA resolved?

DKA is resolved when 1) plasma glucose is <200–250 mg/dL; 2) serum bicarbonate concentration is ≥15 mEq/L; 3) venous blood pH is >7.3; and 4) anion gap is ≤12. In general, resolution of hyperglycemia, normalization of bicarbonate level, and closure of anion gap is sufficient to stop insulin infusion.

Which treatment is useful in decreasing the serum ketone level in patients with diabetic ketoacidosis?

Serum ketone level should be used in the diagnosis and management of DKA. Subcutaneous insulin can be used for treatment of uncomplicated DKA.

Why does DKA need potassium?

Treatment with insulin will cause a shift of potassium intracellularly which can lead to severe hypokalemia and cardiac dysrhythmia. All DKA patients will require potassium replacement to prevent hypokalemia. Generally 20mEq of potassium in each liter of fluid given will maintain a normal serum potassium concentration.

Are DKA patients hyperkalemia?

In DKA, the combination of insulin deficiency and the hyperglycaemia‐induced hyperosmolality frequently leads to hyperkalaemia, even though the patient may be markedly potassium‐depleted owing to potassium losses in the urine secondary to osmotic diuresis [1,2].

Do people with DKA have hyperkalemia?

Patients with diabetic ketoacidosis tend to have somewhat elevated serum K+ concentrations despite decreased body K+ content. The hyperkalemia was previously attributed mainly to acidemia.
