Common electrolyte disturbances in primary care

Abstract

Electrolytes play a vital role in maintaining homeostasis within the body. As GPs, we measure electrolytes commonly when requesting blood tests. As a result, we are often faced with the task of having to interpret and manage abnormal electrolyte results. The most serious and common electrolyte disturbances involve abnormalities of sodium, potassium and calcium. This article aims to provide an overview of the common causes of such electrolyte disturbances and how they are best managed in primary care.
