We often think of âbeing illâ as something purely negative â but nature doesnât make mistakes. As Dr Natasha Campbell-McBride explains, norovirus (the classic vomiting & diarrhoea bug) is incredibly common in humans⊠and surprisingly beneficial.
Animal studies show that norovirus can restore normal gut flora after antibiotic damage. Even more amazing, it also helps return the immune system and the physical structure of the gut wall back to a healthy state.
And while the symptoms can feel dramatic, the illness usually only lasts a couple of days. When you understand its purpose, it doesnât seem such a high price to pay.
Vomiting and diarrhoea are powerful cleansing mechanisms of the digestive system â they flush out toxins, pathogens, parasites and anything causing trouble. Your gut ends up cleaner, clearer and often much healthier afterwards.
Itâs a good reminder that disease is not always the enemy.
Sometimes, your body is simply doing what it was designed to do â heal, cleanse and restore balance.
