Leaky gut syndrome is not real | What's really happening in your gut

Leaky gut syndrome

What is leaky gut syndrome?

Health is not immune (forgive the pun) to fads. The ‘theory’ of leaky gut syndrome has recently resurfaced, and with it, a plethora of treatment articles and advice listicles – how much of it is real though? To find out what leaky gut syndrome is, and what health effects it might have, we have to find what the internal experts are saying about it.

The hypothesis

Leaky gut relates to the intestines, organs in your body that turn the nutrients you digest into their basic components, like sugar, amino acids and fatty acids.

These basic components are able to get into the bloodstream and to where they need to go because the intestines are permeable (permeable simply refers the ability of a material or membrane to allows liquids or gases to pass through it). The levels of permeability are controlled by the intestines ‘tight junctions’.

The hypothesis concerning the syndrome proposes that, when the tight junctions are malfunctioning, the intestines become hyperpermeable. This then allows harmful substances, as well as nutrients, through to the bloodstream.

Is it credible?

Like all ill-defined maladies, leaky gut is said to be a causing factor of a lot of problems, from things as mundane as bloating and as serious as autism. However, there are currently little - if any - credible scientific sources that show definitive evidence between leaky gut and these issues.

There is a logic to it – if a healthy gut does not allow harmful microbes through to the bloodstream, it would follow that an irritated or inflamed gut would.

However, experts in the field (gastroenterologists/gut specialists) don’t refer to leaky gut as a medical diagnosis, and the extensive research performed in relation to leaky gut (intestinal permeability) has produced ambiguous results.

The lack of evidence to support the leaky gut hypothesis has not deterred alternative health outlets from giving advice and selling supplements to try and address the 'ailment', none of which are backed by expert opinion or current scientific understanding.

The danger of leaky gut syndrome treatments

As leaky gut syndrome is an ill usually touted by alternative health and medical sites and personalities, their solutions are also ‘alternative’.

The Canadian Society of Intestinal Research warns that products that claim to help alleviate leaky gut are not medically verified, and may actually be dangerous. Further, dietary advice given by unqualified institutions or personalities may lead to malnutrition or a generally poorer diet.

What to do if you think you have leaky gut

The symptoms of leaky gut can be indicative of a range of other health problems related to the gut, like Crohn’s or coeliac disease, or dysbiosis (imbalance of gut bacteria). We recommend you see your local GP or consult a specialist to see what they recommend.

I joined as a CBHS member in 1978. Through many health events and challenges CBHS has always been there for me and my family. Their exceptional service over this time has always been appreciated.

I've not long joined CBHS from another fund, but so far I've been impressed by the super helpful and friendly staff, the higher claim limits and rebates at a very competitive premium, and how easy it is to lodge manual claims through the app. Thanks CBHS - you've won me over! 😃

I have been with CBHS since I began at CBA 15 years ago...Now I have three beautiful children, one who has a disability. Our top extras cover has been really essential for his early intervention. I do love the ease of claiming online.

What Our Members Think

I am relatively new to CBHS and am loving it already. I worked for a CBA subsidiary a long time ago but was still eligible to join. So much better that the for-profit funds - our premium is only a little more and we pay a lower co-contribution and get great benefits. I am loving the massage rebate for my partner and gym rebate for me!

I'm extremely happy with CBHS! I have been a customer for about six years. I think the price is reasonable. And i would refer you to my family and friends any day. Thank you CBHS!!!

What Our Members Think

Love CBHS as I never have to doubt that they've got my back when I need it. Been through other insurers who have limited options or limits, yet cost the same or more.
