The Appendix – Irrelevant? Or a critical organ of immune defence?

December 1, 2015


Appendicectomy is one of the most commonly performed operations in the developed 

world. And once this part of the colon is inflamed beyond repair, this surgery may be 

necessary and life saving.


But recent research out of Melbourne suggests a new respect for this complicated bit of 

our bodies.


It seems that the reservoir of good bacteria, or probiotics, in our gut is replenished by 

the appendix, to help recovery from things like Bali Belly and to support the gut in all 

of its essential health roles. A network of immune support cells along with good 

bacteria located in the appendix have been shown to provide a resilience against auto-

immune diseases and gut infections  as well as support good digestion and nutrition. 


Of course, for those without this little finger-like protrusion there’s no going back, but 

good gut health becomes an even higher priority post surgery for appendicitis.  


Remember what Hippocrates suggested over 2000 years ago?

“All Health begins in the Gut”


So for those of you who still have an appendix – raise the bar on supporting this organ. 

And for those without, you have a little more work to do to achieve and maintain 

optimal health, regardless of where your starting point is today.
