Hi, I’m Anna Mapson, a registered nutritional therapist mBANT CNHC 

I help clients online from all over the world to

  • manage painful & embarrassing gut symptoms such as excessive gas, bloating, pains and erratic bowel movements)
  • spend less time on the toilet (whether it’s frequent trips or sitting there for 30 mins)
  • eat a varied diet including a range of foods whilst also reducing food fear
  • pinpoint your IBS triggers so you can regain control & focus on living your life!

When was the last time you ate without worrying about your gut?

Most of my clients have forgotten what normal digestion feels like.

If you’re struggling with a hypersensitive digestion, you’re not alone. Maybe you:

  • Spend hours researching new IBS diets and still feel stuck.
  • Eliminate more and more foods, yet can’t identify what’s triggering your flare-ups.
  • Feel trapped in a cycle of trial-and-error diets, constantly second-guessing every symptom.

If this sounds familiar, I can help you stop guessing (and trialling more random supplements) and start doing something about it.

Feeling nervous about discussing your poo?

It’s completely normal to feel hesitant about opening up to someone about bloating, gas, or other gut symptoms. But here’s the thing – I talk about digestion all day, every day in my work. Nothing phases me, and there’s no need to feel embarrassed.

Here’s what you can expect when working with me:

We’ll start where you’re at and move forward together, step by step.

Ongoing support

Weekly calls at the start ensure you feel supported and confident.

Evidence-backed recommendations

I use well-tested and researched diet and lifestyle interventions over social media fads or ‘woo.’

“Working with Anna has been life changing! She guided me through small lifestyle and nutrition changes one step at a time and it’s helped me build lasting habits that support my gut health. I now feel and look healthier than I have in years thanks to her expertise. I highly recommend her to anyone struggling with gut health issues.”

” I specifically wanted help to reduce my long-term reliance on a low FODMAP diet . After completing her suggested diary for 10 days, I sent it to Anna who immediately spotted the type of foods that were triggering symptoms. Over the subsequent 3 months she guided me to avoiding or restricting those foods and reintroducing a range of other foods that I have been excluding or restricting for the past 10 years – as it turns out now, unnecessarily. It has changed my life and my outlook on food. Anna has been patient, understanding and full of practical advice and a great deal of knowledge about food and the FODMAP diet. She suggested some supplements that have been helpful but she has not bombarded me with lots of tests or pills like others have in the past.

At the start of the process I wasn’t sure whether this process would help after so many other failed attempts but it has been a revelation. With each session I have learned something new. Anna also has an extensive set of resources – videos, diary sheets, meal plans, etc which have been a great help. I am no longer aiming in the dark. I know what to eat, what to avoid, and how to manage symptoms if they recur. Thank you to Anna and I wholeheartedly recommend her.”

“Working with Anna has been exactly what I needed. My long-standing IBS became unmanageable as peri-menopause began and my list of ‘safe’ foods started disappearing. Exercise was off the cards and some days, even a loose-fitting elastic waistband was painful. Eating with other people was an issue with my longer and longer lists of things not to feed me – and I would always come home craving what I had seen. After a few flare ups that followed nothing more than eating fruit, I decided it was time for professional advice.
The last few months have changed my mindset completely. I really appreciated Anna taking a holistic view of my health to maximise the benefit of our sessions.
I am now focused on the positive things I can do with my diet and health, both daily and when flare-ups happen. I now have a handle on the combination of triggers that cause flare-ups rather than jumping to conclusions about food culprits. As a result, I now enjoy varied and fear-free eating – and no longer spend hours and money trawling for answers and fixes. The gut re-set course has certainly lived up to its name.”
