Welcome to Guardian featured Harley Street IBS Treatment Clinic London, our Autoimmune Clinic & our Skin Clinic. We offer Skype appointments to patients, who live far away in the UK or abroad.

At our IBS Clinic London and also our skin & autoimmune clinic, we aim to discover the underlying trigger for any symptoms via cutting edge and thorough functional medicine tests. Subsequently, a bespoke treatment plan is created for each patient, which is then modified throughout their recovery process until the body returns to health.

“Deborah, you have completely changed my life! For as long as I can remember, I have suffered physically and mentally. The dreams I’ve always had for my life seemed so far out of reach because of the pain, illnesses and mental health problems I have always had. Now, these dreams are about to become a reality as we embark on our travels in April.

I have always felt failed by doctors with all of the ‘unexplained’ illnesses I have had, to the point where I was believing what everyone around me was saying, that I was a hypochondriac and had completely made all these illnesses/feelings up in my head. I remember the first time I came to your office I was feeling really embarrassed to tell you all my symptoms as I was so afraid of receiving the same treatment I had received for all those years before. Instantly, as I was listing off the, what seemed like, hundreds of symptoms, I finally, for the first time in my life, felt completely heard and listened to. The relief I felt just after that first consultation was incredible. I felt excited to finally be getting some answers and you had my full trust from the get go. Even before you sent me for any tests, you knew exactly what was wrong! I remember telling everyone that would listen, about you and saying ‘she didn’t even have a computer and knew what was wrong’ I was completely in awe of you.

No words could ever be enough to show you my gratitude for the way you have saved my life. I could never have seen myself fulfilling my dreams without you. I am eternally grateful for you and will be forever indebted to you. It doesn’t stop at just me that you have helped in this situation but my whole family. You have given my daughters a healthy, happy and confident mother, and my husband a more hormonally stable wife (he’s definitely extremely grateful for this haha!). You have given my mother the gift of rest and confidence that her daughter will be ok. I won’t be the cause of her worry and sleepless nights anymore.

You are one in a billion and I’m so happy I found you and trusted you. Thank you, thank you, thank you 🙂” – Chyna – London

Deborah Grant is renowned for her successful IBS treatment and also her treatment of skin, bladder and autoimmune disorders. The Autoimmune & IBS Clinic London is located in a medical house in the world famous medical street – Harley Street. We would be delighted to help you with your health concerns.

“When I met Deborah, I was suffering with unbearable abdominal pain all day, every day, no matter what I ate, and even if I didn’t eat. And it did get to the point where I was afraid to eat. I was in agony and had no quality of life whatsoever. That all changed when I started treatment with Deborah.” [Read full testimonial here]

A Few of Our Many Testimonials

Emily-Jane – London

A 36 year female presenting with severe fatigue, fertility issues including a low AMH level; and chronic IBS.

“We are eternally grateful for everything you have done for me over the past two years. I still vividly remember the first appointment I had with you, when I felt so helpless and as if my world was closing in on me. Today I am almost an entirely different person – a healthy, strong, active woman with three triplet girls, who are the light of my life. I could not have achieved this without your help – thank you from the bottom of my heart.”

Lauren – London

A 30-year-old woman presenting with long-term stress and insomnia.

“My fast-paced job left me feeling drained and tired. I felt I could never relax – I was constantly running on adrenaline and felt as though I was not in control of my life. I felt exhausted and yet “wired” all the time. A friend of mine highly
recommended Deborah to me. I was skeptical but I still now cannot believe how fast the natural medicine took effect and helped turn my life around.”

Serena – Cambridge

A 32 year old woman presenting with severe stress.

“Deborah is very professional and thorough in her approach. She covered more ground with me in one hour than doctors had over many months of appointments. The natural medicine she supplied, arrived promptly and was very reasonably priced. It has been more effective than any other conventional medicine I have previously taken. I wish I had found Deborah earlier.”
