Use discount code DOCTIFY10 when booking to receive a unique 10% discount on your initial 60-minute consultation with me at The Gut Health Clinic. The clinic is recognised by major health insurers including Aviva, Bupa, Cigna, Healix, Vitality and WPA.
I'm Joe Alvarez, a specialist gut health dietitian at The Gut Health Clinic, supporting adults with irritable bowel syndrome (IBS) and a range of digestive symptoms. With around 10 years of clinical experience, I combine evidence-based practice with a strong personal understanding of IBS, having lived with the condition myself, and bring a compassionate, highly individualised approach to every consultation.
I offer online consultations, so I can support clients wherever they are based, including Spanish-speaking clients, as I am fully fluent in Spanish. I also provide an affirming, respectful space for LGBTQ+ clients.
How I can help you
I support people dealing with persistent gut symptoms, a new or longstanding IBS diagnosis, or digestive issues that haven't responded to previous advice.
My areas of expertise include:
I also support individuals with:
My approach
Living with IBS myself, I understand how much digestive symptoms can affect confidence, daily life and relationships with food. That personal experience shapes the way I work.
I take an evidence-based, individualised approach, recognising that no two people respond to food, stress or lifestyle factors in the same way. Rather than applying generic advice, I focus on identifying the specific drivers of your symptoms and building a structured, realistic plan that helps you regain control without unnecessary restriction.
The Gut Health Clinic
I work at The Gut Health Clinic, a specialist service led by gut health scientist Dr Megan Rossi (@theguthealthdoctor). The clinic brings together a team of expert gastro dietitians with 80 years of combined clinical experience and has supported more than 5,000 clients since 2018.
We work closely with GPs, gastroenterologists and other healthcare professionals to ensure your care is fully integrated and aligned with your wider medical needs.
What to expect in your first session
Your first appointment is a structured consultation where we take the time to understand your symptoms, medical history, lifestyle and goals in detail.
Following this, you’ll receive a personalised plan with clear, practical steps to move forward. I’ll also guide you on how many sessions you'll likely need, so you have clarity from the outset.
If you have private health insurance (including Aviva, Bupa, Cigna, Healix, Vitality or WPA), your appointments may be covered. Get in touch, and we can guide you through this.

Joe has been an amazing help working through my ongoing low FODMAP issues. He's been incredibly knowledgeable, supportive, and has taken the time to explain everything clearly. I finally feel like I have a plan that's tailored to me, rather than just guessing what foods I can and can't eat. I genuinely feel listened to, and his advice has given me confidence that things can improve. I would highly recommend Joe to anyone struggling with gut health issues.
I had three calls with Dr Joe immediately after my Hb1Ac was at 49. In first call he assured me it’s reversible this was very encouraging. After listening to my daily eating routine he gave specific and clear. dos and donts. In my second call I shared with him my progress - feeling better about 3.5 Kg of weight loss and he reinforced the messages and we agreed to postponement of my blood test for a couple of weeks and results were simply great I moved to 43 a point above normal range and not in diabetic range. Unfortunately the test results came a day after our third and final call and I couldn’t thank him or say good bye as he is leaving the role in NHS. Thanks Dr. You were just Brilliant

Excellent dietician ; extremely knowledgeable, thorough , and not only helpful but practical with his advice and suggestions. One of the best practitioners I have had.
Super clear explanations delivered and all questions answered well. Didn’t feel rushed at all
He was advising me with different places to talk to for support with managing my stomach issue. This made me feel very comforted and heard, showing his willingness to help! Thanks Joe!!
