Why does DKA cause electrolyte imbalance?

Why does DKA cause electrolyte imbalance?

In summary, hyperglycemia in DKA causes an osmotic diuresis, which results in severe fluid and electrolyte deficit. If left untreated, fluid deficit can be sufficiently severe to cause acute renal failure. FIG 2. Osmotic diuresis in DKA causes polyuria, glycosuria and electrolyte depletion.

Why do blood glucose levels increase in DKA?

Our bodies need insulin to use the available glucose in the blood. In DKA, glucose can’t get into the cells, so it builds up, resulting in high blood sugar levels. In response, the body starts breaking down fat into a useable fuel that doesn’t require insulin.

Why is electrolyte and fluid replacement important in DKA?

Fluid resuscitation is a critical part of treating patients with DKA. Intravenous solutions replace extravascular and intravascular fluids and electrolyte losses. They also dilute both the glucose level and the levels of circulating counterregulatory hormones.

Why is total body potassium low in DKA?

Total body potassium depletion is expected in DKA largely due to osmotic renal losses.

What happens if you have too many ketones in your blood?

When ketones build up in the blood, they make it more acidic. They are a warning sign that your diabetes is out of control or that you are getting sick. High levels of ketones can poison the body. When levels get too high, you can develop DKA.

Will potassium be high or low in DKA?

Patients in DKA are low in total body potassium and their serum concentration is falsely elevated due to extracellular shift. On average, patients will have a potassium deficit of 3-5 mEq/kg.

Is potassium low or high in DKA?

When should potassium be given in DKA?

About two-thirds of patients will develop hypokalemia in the course of treatment for DKA. Potassium repletion should commence once the serum potassium falls below 5.3 mEq/L if patients have normal renal function. Twenty to 30 mEq of potassium may be supplemented to each liter of fluids.

What causes confusion in DKA?

Patients may present with a history of failure to comply with insulin therapy or missed insulin injections due to vomiting or psychological reasons. Decreased perspiration is another possible symptom of DKA. Altered consciousness in the form of mild disorientation or confusion can occur.

What are the symptoms of electrolyte deficiency?

Electrolyte Deficiency Symptoms. The commonest manifestations are: Exhaustion. Muscle cramps and spasms. Restlessness. Nausea, vomiting.

What is the expected anion gap in diabetic ketoacidosis (DKA)?

In patients with diabetic ketoacidosis, the anion gap is elevated ([Na + K] – [Cl + HCO 3] greater than 10 mEq/L in mild cases and greater than 12 mEq/L in moderate and severe cases).

What are electrolyte problems?

An electrolyte disorder occurs when the levels of electrolytes in your body are either too high or too low. Electrolytes need to be maintained in an even balance for your body to function properly. Otherwise, vital body systems can be affected.
