Electrolytes Archives

Tag: Electrolytes

Electrolytes are chemicals that conduct electricity when mixed with water.

They regulate nerve and muscle function, hydrate the body, balance blood acidity and pressure, and help rebuild damaged tissue.

The muscles and neurons are sometimes referred to as the “electric tissues” of the body. They rely on the movement of electrolytes through the fluid inside, outside, or between cells.

The electrolytes in human bodies include:

sodium
potassium
calcium
bicarbonate
magnesium
chloride
phosphate

For example, a muscle needs calcium, sodium, and potassium to contract. When these substances become imbalanced, it can lead to either muscle weakness or excessive contraction.

The heart, muscle, and nerve cells use electrolytes to carry electrical impulses to other cells.

Spotlight: Potassium in Neuroendocrine Tumours (NETs)

A spotlight on NENs, Diet and Nutrition, Patient AdvocacyElectrolytes, Potassium

Before you read this This information is designed to help you understand how vitamins and minerals work in the body and how certain NET-related factors might affect them. It is not a substitute for personalised medical advice. Every NET patient is different — tumour type, treatments, surgery, symptoms, and nutritional needs can vary widely. If you have concerns about vitamin levels, supplements, or symptoms, please speak with your NET clinical team. They can assess your individual situation and guide you safely. Potassium is one of the most tightly regulated electrolytes in the body. Even small deviations can affect muscle strength,…

Originally published 2016, updated October 2025 Background Some people hear the terms "tumour markers" and "hormone levels" when they are diagnosed with Neuroendocrine Neoplasms (NENs). That might be confusing or even alarming at the time. Most people diagnosed with cancer will have had a form of medical testing at some point in their life, i.e. the sampling and testing of blood, urine, saliva, stool or body tissue. With NENs, the medical staff are just measuring the content of a 'substance' and then taking a view whether this is normal or not based on pre-determined ranges. These tests are normally done…
