Electrolytes: wellness must-have…or overhyped? What people with IBD really need to know

Electrolytes are everywhere right now - Powders, tablets, drinks - all promising more energy, better hydration and “balance”.

But…do we actually need them?

Firstly, what are electrolytes?

Electrolytes are minerals like:

  • Sodium

  • Potassium

  • Chloride

They help with fluid balance, nerve signalling and muscle function.

They’re essential but more isn’t always better.

Electrolyte drinks ≠ rehydration solutions

This is where thing can get confusing.

  • “Electrolyte” drinks contain varying concentrations of electrolytes (e.g. sodium, potassium, chloride, bicarbonate)

  • Oral rehydration solutions (ORS) are specifically designed to treat dehydration

They are not the same thing.

Why ORS are different (and important)

ORS use a clever gut mechanism where

glucose + sodium = better water & sodium absorption

They contain:

  • A precise ratio of sodium, glucose and other electrolytes

  • The right osmolarity to maximise absorption

  • Evidence behind them (used worldwide in diarrhoea)

This is why ORS can be recommended in IBD flares with diarrhoea.

When electrolytes or ORS are helpful

  • During IBD flares with diarrhoea, if you’re dehydrated

  • For ileostomy or J-pouch patients (post-surgery or ongoing, if needed)

  • During significant fluid losses (e.g. vomiting, high output)

When they’re usually not needed

If you are:

  • In remission

  • Eating a varied diet

  • Not losing fluids through diarrhoea or sweat

In these cases, food and fluids are usually enough to meet electrolyte and hydration needs.

Routine, “just in case” electrolyte use isn’t evidence-based and could be harmful.

Why ‘more’ can be a problem

Unnecessary use can lead to:

  • Excess sodium intake

  • Electrolyte imbalances

  • Potential cardiovascular or kidney strain (in some people)

Bottom Line

Most people don’t need electrolyte or hydration supplementation.

Their use should be guided by need, not trends.

Confused about food, supplements & IBD?
