IBS Nutritionist


One-to-one support for people with IBS, or IBS-type symptoms, who are tired of guessing.

Bloating that builds through the day. Constipation, diarrhoea, or both in the same week. Pain that comes and goes without an obvious pattern. Most of the people I work with have already tried cutting out gluten or dairy, a round of probiotics, maybe the low FODMAP diet. Some things helped for a while. Nothing has stuck.

I’m a registered nutritional therapist specialising in gut health. I work with people across the UK by video call, and in person in Hove by arrangement.

IBS is a label, not an explanation

IBS is diagnosed from a pattern of symptoms, once your GP has ruled out other conditions. That diagnosis matters, but it describes what is happening rather than why. Two people with the same IBS diagnosis can have completely different things driving their symptoms, which is why one person’s fix does nothing for the next.

My job is to work out which drivers are relevant to you, then deal with them in a sensible order. The ones I look at most often:

  • How you digest your food. Stomach acid, bile and enzymes set up everything that happens further down the gut.
  • Bacterial overgrowth. SIBO is more common in people with IBS-type symptoms, especially when bloating is the main complaint. How I work with SIBO.
  • What started it. Symptoms that began after food poisoning, a course of antibiotics or a stressful period often point in a particular direction.
  • Gut motility. How well food moves through, which is affected by meal timing, sleep and stress.
  • The gut-brain connection. Your nervous system has a direct line to your gut. For many people this is the missing piece.
  • Food reactions. Real ones, identified properly, rather than an ever-growing list of foods you’re scared of.

Where low FODMAP fits

The low FODMAP diet has good evidence behind it for IBS, and it can be really useful. But it’s designed as a short elimination phase followed by careful reintroduction, so you end up eating as widely as possible. A lot of people never get past the first phase. They stay restricted for months, sometimes years, and their diet gets narrower while the symptoms don’t fully go away.

If that sounds like you, part of our work is usually getting foods back in, in a structured way, rather than taking more out.

See your GP first if any of these apply

Nutritional therapy works alongside medical care, not instead of it. Please see your GP before booking if you have:

  • Blood in your stool, or black, tarry stools
  • Weight loss you can’t explain
  • Anaemia, or extreme tiredness that isn’t going away
  • Symptoms that wake you up at night
  • A new change in bowel habit, particularly if you’re over 50
  • Persistent bloating if you’re a woman over 50
  • A family history of bowel cancer, ovarian cancer, coeliac disease or inflammatory bowel disease

One more: if you haven’t been tested for coeliac disease, ask your GP about it before cutting out gluten. The blood test only works if you’re still eating gluten regularly.

How I work with IBS

Most clients join my 16-week programme, Restore Revive Thrive. In short:

  • A free 30-minute discovery call to talk through your symptoms and whether I can help
  • A 90-minute initial consultation covering your history, diet, sleep, stress and medication
  • Testing only where it changes the plan, such as a breath test for SIBO or a comprehensive stool test
  • A phased plan covering nutrition, lifestyle and movement, with check-ins every two weeks

It’s £350 a month for a minimum of four months, with any testing paid to the lab separately. See everything that’s included on the Work with Me page.

Questions about IBS support

Should I see a nutritionist or a dietitian for IBS?

Both can help, and it’s worth knowing the difference. Dietitians are regulated by the HCPC, work in the NHS and privately, and many specialise in IBS and the low FODMAP diet. Your GP can refer you to one. Nutritional therapists like me are registered with the CNHC, work privately, and tend to look more widely at digestion, lifestyle, stress and testing alongside diet. If you’re unsure which suits you, the discovery call is a good place to talk it through.

Do I need an IBS diagnosis to work with you?

No, but I’d always recommend seeing your GP first so other conditions can be ruled out. Many people I work with have IBS-type symptoms and are still waiting for answers.

Can testing diagnose IBS?

No. IBS is diagnosed by your GP. Functional tests, like a breath test for SIBO or a comprehensive stool test, can help us understand what might be driving your symptoms and shape the plan. We only use them when the result would change what we do.

Will I have to cut out lots of foods?

Usually the opposite. Most people come to me already eating a narrow diet. The aim is to understand what’s going on so you can eat more widely, not less.

I’ve already tried low FODMAP. Is there any point?

Yes. Many of my clients have. Often the elimination phase went fine but the reintroduction never happened properly, or other drivers like digestion, motility or stress were never looked at.

Do you work online?

Yes. Most clients work with me by video call, from anywhere in the UK. In-person appointments in Hove are available by arrangement.
