IF you ever go to the loo and what comes out seemingly vanishes without a trace, then you've had what's known as a "ghost poo".

Similarly, if you've wiped your behind and there's been nothing on the toilet roll, that too is an elusive number two.

Both can be incredibly satisfying, but also rather baffling.

The good news is, experts say they're both signs your gut is in good health.

Naturopathic doctor Janine Bowring even went as far as to say: "If you have this type of poop, you might just be the healthiest person on the planet."

...

Dr Philippa Kaye, an NHS GP, agreed that faeces passing without trouble is an indicator of good health.

She said: "Stool which is easily passed without straining yet isn't too loose can be a healthy stool as it is not constipation or diarrhoea."
