It starts with a slight ache—something easy to ignore. Then comes the bloating, the sudden stomach pain, and the worry of not knowing when it will happen again.
If you’re living with IBS, Crohn’s disease, or any digestive disorder, you know how much it controls your life. Even simple things, like enjoying a meal out with friends, become a gamble.
You’re not alone. In fact, one in four people in the UK experiences a digestive issue at some point.
The good news? London is home to some of the best gastroenterologists who treat symptoms and help you take back control.
Let me help you to find the right expert for you.
How much does a Gastroenterologist Consultation cost in London?
Private gastroenterology consultations in London cost between £200 and £350 for the first appointment, with follow-ups ranging from £150 to £250, depending on the specialist and clinic. NHS consultations are free with a GP referral, but waiting times may vary.
How we chose the best Gastroenterologists in London
- Expertise and specialisation: I checked the British Society of Gastroenterology (BSG) to find doctors involved in research and new treatments, ensuring they offer the latest care.
- Hospital and clinic affiliation: I considered specialists working in trusted London hospitals and private clinics that I or people I know have visited, focusing on those with advanced diagnostic tools.
- Consultation availability: I called clinics and booked appointments to find doctors with short wait times, making sure patients can get care quickly when needed.
- Patient Care: I spoke with patients to learn about their experiences and prioritised doctors who listen, explain clearly, and provide long-term care instead of just quick prescriptions.
1. Dr Marcus Harbord
Areas served: Chelsea and Westminster Hospital
Phone: +44 20 3096 5840
Dr Marcus Harbord’s patients frequently praise his thorough approach. Those I’ve talked to shared that he takes the time to understand their symptoms in detail—covering everything from diet and stress levels to medical history—before recommending any further tests.
We also appreciate his methodical diagnostic approach, which sometimes includes ultrasounds and blood work to ensure an accurate diagnosis.
Patients also love that he includes lifestyle changes as part of the treatment plan, helping them take an active role in their care.
Follow-up care is another strong point. His patients praised his well-organised follow-up appointments, which allow for regular monitoring.
That said, availability for in-person appointments is limited. He does, however, offer online consultations as a more accessible option.
Professional and compassionate
“I had the pleasure of being treated by Dr. Marcus Harbord, and I couldn’t be more impressed. From the moment I walked into his office, I felt welcomed and at ease. Dr. Harbord took the time to listen to my concerns, thoroughly explained my treatment options, and ensured I was comfortable throughout the process. His professionalism and compassionate care truly set him apart. I highly recommend Dr. Harbord to anyone seeking top-notch gut related care.”

2. Dr Alberto Murino – 39.6
Areas served:
Phone: +44 7518 530406
Dr Alberto Murino is a gastroenterologist and advanced endoscopist, often recommended for his expertise in IBS, minor bowel diseases, and complex procedures.
A friend of mine had been struggling with persistent bloating and discomfort, and while researching options, I noticed Dr Murino’s name kept appearing. He was often praised for his thorough and patient-focused approach.
His involvement in medical research and education stood out to me even more. He has authored over 70 peer-reviewed publications and is a reviewer for leading endoscopy journals, which speaks to his deep expertise in the field.
While accompanying my friend to her consultation with Dr Murino, I spoke with other patients in the waiting area. Many highlighted his attention to detail and willingness to explore less common diagnoses.
Dr Murino’s approach focuses on long-term management rather than symptom relief, which many found reassuring.
However, some noted that appointment availability can be limited due to his busy schedule.
Precise and careful
“I got in contact with Dr. Murino as I am experiencing problems with my stomach and digestion and he’s been very precise and careful to suggest new examinations and tests to understand where the problem originates. I appreciate is personable approach and the fact that he’s explained everything in detail!”

3. Dr Alistair McNair 40.9
Areas served:
Dr Alistair McNair has been a gastroenterologist for nearly 40 years, and his experience in IBS, Crohn’s disease, acid reflux, and bowel cancer screening really shows.
His name frequently comes up in discussions about top specialists, and patients often describe him as thorough, clear, and professional. Some also mentioned that he is patient and takes time to answer questions, which helps build confidence in the treatment plan.
He is known for taking a structured approach to diagnosis and treatment. He focuses on patterns in a patient’s symptoms over time rather than relying solely on test results.
We also appreciate that he looks at how lifestyle, diet, and underlying conditions interact, making his recommendations more tailored to their specific needs.
However, other patients mentioned that appointment wait times can be longer than expected, especially for new consultations.
Intelligent, kind, and caring
“Intelligent, kind, caring and an expert in his field, Will leave no stone unturned.
Dr. Mc Nair will put you at your ease, and try his hardest to get to the bottom of your trouble. He will keep going until he has solved the problem. I cannot recommend Dr. McNair highly enough.”

4. Mr Borzoueh Mohammadi – 44.3
Areas served:
- University College Hospital
- Cleveland Clinic Hospital
- Cleveland Clinic Portland Place Outpatient Centre
Mr Borzoueh Mohammadi is a consultant surgeon who treats serious digestive problems and performs stomach and intestinal surgeries. My colleague introduced me to him, as he was their surgeon at the time.
To learn more about his expertise, I spoke with patients in a post-surgery support group and researched more about him. Many patients said they were sent to him after other treatments didn’t work, showing his experience with difficult cases that need surgery.
Patients describe him as calm and reassuring. He takes time to explain their condition and what to expect. One patient shared that he made the procedure easy to understand without using complicated medical terms.
However, some patients felt that recovery advice after surgery could be clearer, especially about long-term care and what to expect after leaving the hospital.
He was the kindest and gentlest doctor
“Mr Mohammadi – Boz – is not only a highly skilled surgeon, but one of the kindest, gentlest doctors imaginable. He cared for me as if I was a member of his family and I felt safe in his experienced hands. I trusted him completely despite the major surgery I faced (extended total gastrectomy). My cancer diagnosis was a shock and the treatment is challenging in the extreme but it really helped me to deal with that knowing that I had such a great surgeon. My surgery was successful and words cannot express the debt of gratitude I feel to Mr Mohammadi. He always spoke to me as an equal. He never patronised or minimised things to me, but always remained reassuring and positive seeking the best possible of outcomes that could be achieved.
He was vey humble in his manner, praising his junior team and his oncology and radiotherapy colleagues. He always made the effort to speak to me personally afterwards for instance if he was not on the ward round. I felt that I really mattered to him and feel incredibly lucky that he was able to save my life.
He has a ‘can do’ attitude no matter how big or small the task. In outpatient clinic he did my wound dressing rather than pass me on, and did the administrative booking with a tricky IT system to get me seen by a cardiologist.
When I said how difficult recovery was proving he listened and understood, and reassured me that this was not unusual after such major surgery and gave advice going forward.
I felt very included and very expertly cared for by Mr Mohammadi and cannot praise him enough.”

5. Dr William Alazaw 38.5
Areas served:
Dr William Alazawi is a consultant gastroenterologist and professor who treats digestive disorders and liver disease.
I first learned about his work through the European Association for the Study of the Liver (EASL) after reading public discussions on his medical conference presentation.
While these events are mainly for doctors and researchers, I followed public discussions to understand his approach.
I really appreciate his focus on finding digestive problems early and encouraging lifestyle changes like diet and stress management to help with conditions such as acid reflux and fatty liver disease.
Patients say he is thorough and careful, looking at all aspects of their health before deciding on treatment.
He is skilled in endoscopy and colonoscopy, which help diagnose issues accurately. Plus, he explains test results in a way that is easy to understand.
However, because of his research and teaching work, he may not always have time for long discussions during appointments.
Very sympathetic
“I’ve seen Dr Alazawi for the last three years after some odd liver results following my company medical. He was exactly what I needed – sympathetic, extremely knowledgeable and explained clearly what was going on. I would recommend anybody to see him.”
