The plasma potassium concentration is determined both by external potassium balance and by the distribution of potassium between extracellular and intracellular fluid compartments, i.e., "internal potassium balance." Whenever external potassium balance is altered, the resultant change in the plasma potassium concentration is strongly influenced by concomitant alterations in internal potassium balance. Several factors alter internal potassium balance independently of changes in external balance… 
Hyperkalemia: Disorders of Internal and External Potassium Balance
TLDR
The serum potassium level is normally preserved de spite changes in potassium intake and output and changes in its distribution in the body (the internal potassium balance), which depends on the extrarenal regulation of potassium.
Physiology and Pathophysiology of Transcellular Shift of Potassium Balance
TLDR
The physiology of potassium distribution is important to evaluate and manage the patients with potassium disturbances including hypokalemia or hyperkalemia and drugs that alter internal potassium balance would appear to be un-common.
Potassium Homeostasis

TLDR
The average potassium intake in the United States population ranges from 90 to 120 mEq/day; however, a recently recognized feedforward mechanism acting independently also helps preserve potassium homeostasis, vital for humans to function at a normal level.

Abnormalities of serum potassium concentration in dialysis-associated hyperglycemia and their correction with insulin: a unique clinical/physiologic exercise in internal potassium balance
TLDR
The lessons from analyzing serum K+ changes during treatment of DH with insulin are applicable to other conditions where internal potassium balance is called upon to protect serum K+, such as the postprandial state.
Nonrenal Potassium Homeostasis: Hypokalemia and Potassium Depletion—Role of Skeletal Muscle Potassium-Pump (Na+,K+- ATPase)
TLDR
The physiology of potassium homeostasis is discussed in relation to clinical experience and the possible basis for a rational approach to disturbances of potassiumHomeostasis in clinical practice is discussed.
Plasma potassium and phosphate concentrations--influence by adrenaline infusion, beta-blockade and physical exercise.
TLDR
From measurements of the ion concentrations both in the femoral effluent of one leg, which carried out maximal isokinetic work, and in the opposite antecubital vein it could be calculated that there was for potassium, but not for phosphate, a post-exercise uptakeboth in the exercised muscle and inThe entire organism, indicating the participation of systemic factors.
Potassium and the Dyskalemias
TLDR
This chapter reviews the cellular and molecular physiology of potassium homeostasis, the pathophysiology of hypokalemia and hyperkalemia, and the diagnosis and clinical management of the dyskalemias.
Potassium imbalance: causes and prevention.

TLDR
The key to understanding and treating potassium imbalance is to know which patients are at risk, what the physiologic consequences of hypokalemia and hyperkalemia are, and how to use urinary potassium measurements and the ECG for prevention rather than relying on the serum potassium level only.
Plasma Potassium Changes in Anuric Hyperglycemia Treated with Insulin
TLDR
The change in potassium concentration is dependent on the starting potassium concentration, hyperkalemic patients will drop their plasma potassium concentration toward normal, and hypokalemic Patients may not need potassium replacement.
