Is hyperkalemia common in diabetics?
Hyperkalemia occurs frequently in patients with longstanding diabetes mellitus. This is usually due to the presence of multiple pathogenic factors (see “Causes and evaluation of hyperkalemia in adults”). The hyperkalemia is usually related at least in part to the presence of diabetic nephropathy.
What are 3 Causes of hyperkalemia?
The leading causes of hyperkalemia are chronic kidney disease, uncontrolled diabetes, dehydration, an injury causing severe bleeding, consuming excessive dietary potassium, and some medications.
Why does diabetes cause hypernatremia?
Glycerol, mannitol, and occasionally urea can cause osmotic diuresis resulting in hypernatremia. The most common cause of hypernatremia due to osmotic diuresis is hyperglycemia in patients with diabetes.
Why does hypokalemia occur in DKA?
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.
Why does hemolysis cause hyperkalemia?
Any increase in plasma (or serum) potassium resulting from in vivo hemolysis is true hyperkalemia. By contrast, in vitro hemolysis is a process that only occurs in blood removed from the body and is due to mechanical disruption of erythrocytes induced by the process of blood collection and handling.
Does insulin cause hypokalemia?
Insulin therapy lowers K+ concentration driving K+ into cells (both directly and indirectly by reversing hyperglycemia). Therefore, insulin therapy may cause severe hypokalemia, particularly in patients with a normal or low serum K+ concentration at presentation.
Can diabetes cause hypokalemia?
The causes of hypokalemia in diabetics include: (1) redistribution of potassium [K+] from the extracellular to the intracellular fluid compartment (shift hypokalemia due to insulin administration); (2) gastrointestinal loss of K+ due to malabsorption syndromes (diabetic-induced motility disorders, bacterial overgrowth.
