Your gut does far more than digest your food. Amongst many other things, it plays a role in making your neurotransmitters, it influences your hormones and it’s also home to most of your immune system. This means that if something isn’t right in your gut, it can show up in a number of ways—headaches, skin conditions, joint pain and more. To look at it another way: there are very few conditions that can’t be helped by addressing the gut. If you recognise yourself in any of the symptoms listed above, it may be worth taking a test.
