Short answerA gut health nutritionist helps you work out what is driving symptoms like bloating, IBS and irregular digestion, then builds a food and lifestyle plan around your own pattern rather than a standard list. In the UK, look for someone registered with BANT, CNHC, the AfN or the BDA, expect to pay £80 to £200 for a first consultation, and rule out anything that needs a doctor before you start.
What a gut health nutritionist actually does
- Takes a full history. Symptoms, timing, food, sleep, stress, medication, past tests. The pattern matters more than any single food.
- Builds a personalised plan. Practical, based on what you actually eat and how your week actually runs.
- Runs a structured process, not a guess. If foods are removed, they are removed for a defined period and reintroduced properly, so you end up with fewer restrictions, not more.
- Covers the parts that are not food. Meal speed, meal spacing, sleep, stress and movement all change gut symptoms.
- Knows when to stop and refer. A good practitioner sends you to your GP when the symptoms warrant it.
Nutritionist, dietitian or nutritional therapist?
Dietitian is a protected title in the UK, regulated by the HCPC. Dietitians can work in the NHS and treat diagnosed medical conditions. If you have a diagnosis, ask your GP for a referral first, because it is free.
Nutritionist is not a protected title, which is why the register matters. Registered Nutritionists appear on the UK Voluntary Register of Nutritionists, run by the Association for Nutrition.
Nutritional therapist usually means personalised practice with individuals, typically registered with BANT and the CNHC.
For everyday gut symptoms without a diagnosis, any of these can help. The question is not the job title, it is whether they are registered, whether they work from evidence, and whether they will tell you when to see a doctor. There is more detail in our guide to the difference between a nutritionist and a dietitian.
How to find one in the UK
- Search a register. The BDA find a dietitian directory, the AfN register, the CNHC register, BANT, or Nutritionist Resource. Every practitioner there has had their credentials checked.
- Check they actually specialise in gut health. Plenty of good nutritionists work mainly in sport or weight. Digestion is its own area.
- Read how they describe their process. You are looking for a structured method with a defined length, not an open ended series of appointments.
- Look for someone who publishes. Articles, books or talks tell you how they think before you pay them.
- Ask about the whole cost. Consultation, follow ups, tests and supplements. Get the full number before you start.
One example of a structured programme: The Gut Code is four weeks, four private sessions, a personalised plan and a proper reintroduction process, £500. See what is included.
What it costs in the UK
- First consultation: usually £80 to £200, for 60 to 90 minutes
- Follow ups: £50 to £120
- A structured multi week programme: £300 to £900 depending on how many sessions are included
- NHS dietitian: free with a GP referral, if you have a diagnosed condition, though waiting lists are long

Online or in person?
For gut work, online is genuinely as good. There is no physical examination involved, the work is conversation, review and planning, and video means you are not limited to practitioners within driving distance. It also makes follow ups far easier to keep, which matters more than the format of the first appointment.
Five questions to ask before you book
- Which register are you on, and what is your registration number?
- How many clients do you see with symptoms like mine?
- What does your process look like, week by week?
- Do you earn commission on any supplements or tests you recommend?
- At what point would you tell me to see my GP instead?
Red flags
- Promises to cure IBS, or to fix your gut in a fixed number of days
- Selling an expensive food intolerance or microbiome test as the first step
- A long list of foods removed at the start with no plan for bringing them back
- Supplements sold from their own shop as the centrepiece of the plan
- No mention of when you should be seeing a doctor instead
See your GP first if
You have unexplained weight loss, blood in your stool, persistent pain, difficulty swallowing, vomiting, a family history of bowel or ovarian cancer, or a sudden change in bowel habit, especially over the age of 50. Nutrition work comes after those are ruled out, not instead of.

Outside the UK? The same criteria apply, with different registers. In the United States look for a Registered Dietitian Nutritionist (RDN) or a Certified Nutrition Specialist (CNS). In Canada, a Registered Dietitian (RD). In Australia, an Accredited Practising Dietitian (APD) or a member of the Nutrition Society of Australia. Online consultations mean you are not limited to practitioners in your own country: see working with a UK nutritionist from abroad.
