Why Gut Problems Can’t Be Ignored

At least one in five people experience digestion problems. Yet, these are often dismissed as just mildly annoying symptoms. Abby explains how ignoring gut issues often leads to any number of other health issues. That’s why it’s important to treat the root causes of digestion problems.

The tricky part is identifying what is wrong in the first place. It’s not enough to just cut out certain foods. In fact, elimination diets don’t really fix anything. They can even cause problems if continued for too long.


The Common Causes of GI Issues

Abby explains what the three generalized root causes of IBS are. There can be many different factors at play, but Abby finds that it usually involves one or more of just three situations. The first is digestive insufficiency – when someone is not producing or excreting the optimal digestive substances. Sometimes there’s dysbiosis or a GI infection at play. Inflammation is also a common culprit. Once you know what’s going on in the gut, you can make a roadmap for healing.

Sometimes these can be remediated with lifestyle changes, like slowing down and thoroughly chewing food. Targeted supplement protocols can also help to reverse some of the problems. That’s why it’s useful to work closely with a practitioner who understands how to help you help your digestive system.

“Food can certainly be a tool in a treatment protocol that can help to alleviate some of these symptoms while we get to the root cause… but it is not a tool that we can use to fully heal a digestive system.” [16:36]

“We do need to create a lifestyle shift around the way that we eat in order to optimally digest our food.” [24:30]

“We really want to identify in someone’s unique body which of those three are that root cause and then in those three categories, what exactly is really going on.” [27:28]
