Dr. Nicki Gill

MBChB MRCGP AFMCP

Hi there! I’m Dr. Nicki Gill, and I’m thrilled to welcome you to our functional medicine practice. With several years of experience as an NHS General Practitioner, I’ve developed a strong interest in women’s health and neurodiversity. My journey began in Warwickshire, where I trained and worked as a GP. I progressed to become Clinical Lead, overseeing several GP practices, and eventually took on leadership roles, including my position as Medical Director for urgent care and out-of-hours services in the West Midlands.

Dr Meera Rajah

MBBSc MRCGP MEd MRCEM DRCOG DFSRH DCH AFMCP

Hi, I am Dr Meera Rajah, working NHS GP , for over 10 years and GP partner for 8 years where I have developed my interest in women’s health and dermatoscopy. Following qualifying from Imperial College London,  I have always been interested in acute medical care so I still do surprisingly enjoy a busy triage session as a NHS GP! With worrying data such as obesity doubling since 1990 and the prevalence of cancer increasing every year, we really do need to look at the root causes of illness and symptomatology.

Our Approach

We believe every person's healing story is unique. That's why our process begins with a thorough intake review, followed by a 1-hour deep-dive consultation where we go over your full health history, symptoms, and goals. Based on the findings, our practitioners will put together a personalized treatment plan that will address the root causes of imbalance, rather than just the symptoms.

How the Methylation Health Test Works

The process is simple and non-invasive. You'll receive a collection kit for a saliva or blood sample, which is then sent to one of our certified partner laboratories. Your sample is analyzed for variations in key methylation-related enzymes such as MTHFR, COMT, and MTRR genes that influence detoxification, energy production, and hormone regulation.

The Functional Medicine Advantage

At Functional Doctors, we take a holistic approach by analysing how gut, toxins and hormones connect to immunity and energy. By applying functional medicine principles, our practitioners get to the 'why' of your symptoms. Sometimes we recommend heavy metal testing or nutrition testing to complete a view of your body's internal balance.
