How does hypokalemia cause polyuria
WebHow does hypokalemia cause polyuria? Remember that potassium is recycled via the apical ROMK channel, which facilitates ongoing sodium reabsorption in the TAL and maintenance of the medullary concentration gradient. Therefore, potassium deficiency may lead to concentrating defects via this pathway, leading to polyuria. WebHypokalemia is defined as a serum K + level <3.5 mmol/L and is one of the most common electrolyte disorders. It can be associated with either a decreased or a normal total body potassium content. It is important to remember that the cause of hypokalemia can be multifactorial, with the involvement of more than one mechanism or etiology.
