You’re probably well aware that constipation helps normally starts with ‘eat more fibre’.
And yes, increasing fibre really definitely does help some people. (It’s certainly somewhere I’d start with if you occasionally have constipation, or you haven’t yet worked on your diet.)
But, if you’re already eating a really high-fibre diet and you’re still constipated, adding even more fibre might not be helping. And it could even make things worse.
And if you’ve got something like pelvic floor dysfunction, adhesions or a motility problem slowing the passage through your gut, more fibre isn’t necessarily going to make things move faster.
So before you add another handful of bran to your breakfast think about whether you need more fibre, or a different approach to eating.
