These are common complaints that many people experience, yet they are also some of the most frustrating to understand. They can be vague, overlapping, intermittent, and difficult to pin down. Blood tests may come back as “normal”. Symptoms may be attributed to stress, lifestyle, digestion, hormones, ageing, or the simple pressures of modern life.

But in many cases, there may be another layer worth examining. Nutritional and micronutrient deficiency. Symptoms such as fatigue, hair loss, gut problems, and brain fog are often described as “non-specific.” That does not mean they are unimportant. It means they can have many possible causes, and therefore deserve an unhurried, careful assessment.

On 18 May 2026 at 2:30pm, Harley Street Health Centre will be hosting a practical, case-based session titled, Fatigue, Hair Loss, Gut Symptoms & Brain Fog: A Practical Guide to Nutritional Causes. The session will be led by Dr Enam Abood, founder and head doctor of Harley Street Health Centre, and will explore how nutritional deficiencies can contribute to some of the most common health concerns seen in everyday practice.

A person experiencing persistent tiredness may be dealing with low iron stores, poor sleep, hormonal imbalance, thyroid issues, B12 deficiency, vitamin D deficiency, chronic stress, inflammation, gut absorption problems, or a combination of several factors. Hair loss may be linked to ferritin levels, thyroid function, nutritional intake, recent illness, hormonal changes, or wider health disruption. Gut symptoms may affect nutrient absorption, while nutrient deficiencies can, in turn, worsen general health and wellbeing.

This is where a practical, clinical approach matters.

Not every symptom is caused by a deficiency. Not every borderline result needs treatment. But nutritional causes are sometimes overlooked, particularly when symptoms do not fit neatly into one diagnosis.

When dealing with complex, persistent symptoms, a standard, time-pressured consultation is rarely enough. Harley Street Health Centre operates differently. We are not just a generic private GP service. We are a premium, integrated GP and diagnostics clinic designed to be your whole-journey coordination partner.

For busy City executives requiring discreet, rapid answers, international expats seeking a trusted central hub for their healthcare in London, or anxious patients who need reassurance and unhurried listening, fragmented care is simply not an option. Our model is built on seamless pathways: from a depth of initial assessment and same-day integrated diagnostics to structured, doctor-led follow-up.

We pride ourselves on operational excellence and clear communication. When you test with us, you benefit from transparent next steps, reliable turnaround expectations, and automatic updates on your results. Should your symptoms require specialized intervention, we provide straightforward escalation routes, acting as intelligent coordinators alongside NHS specialists or top private consultants to ensure your care is managed comprehensively over the long term.

Looking Beyond “Normal” Test Results

One of the key themes of this session will be how to interpret results in context. Many patients are told their results are “normal”, yet continue to feel unwell. In some cases, this is because the result genuinely does not explain the symptoms. In others, the result may sit within a laboratory reference range but still be clinically relevant when considered alongside the patient’s history, diet, menstrual health, or underlying chronic conditions.

For example, a result at the lower end of normal may mean different things for different people. A patient with diffuse hair shedding, heavy periods, and low-normal ferritin requires a customized care pathway, whereas someone with no symptoms and the same number on paper may not. This tailored, patient-centred approach prevents the dismissal of genuine symptoms and the over-treatment of mere numbers. Dr Enam Abood will discuss:

When nutritional causes should be considered. The session will explore the types of symptoms, histories and risk factors that should prompt a closer look at nutritional status. How to interpret borderline or “normal” results. Attendees will consider how blood results should be understood in relation to symptoms, clinical context and patterns over time.

Common pitfalls in diagnosis and management. Nutritional medicine can be oversimplified. The session will look at where deficiencies are commonly missed, where supplements are used without enough investigation, and where further assessment may be needed.

When and how to investigate effectively. The focus will be on practical, appropriate investigation. What to test, when to test, when to repeat, and when to look deeper for causes such as absorption issues or underlying medical conditions.

The event will focus on several common presentations, including:

Fatigue
Persistent tiredness can be caused by many factors, but nutritional deficiencies are an important part of the picture. Iron, B12, folate, vitamin D, magnesium, protein intake, and overall dietary quality may all be relevant depending on the individual case. We look at long-term management strategies rather than just one-off fixes.

Hair loss
Diffuse hair shedding can be distressing, especially when there is no obvious cause. Nutritional status, iron stores, thyroid health, recent illness, stress, hormonal changes, and diet can all play a role. Our integrated diagnostics allow us to assess these factors rapidly and thoroughly.

Gut symptoms
Bloating, altered bowel habits, discomfort, and suspected food intolerances can severely affect your quality of life and influence nutrient absorption. Gut symptoms can sometimes be both a cause and a consequence of wider health imbalances.

Brain fog
Difficulty concentrating, poor mental clarity, and low cognitive stamina are often difficult to measure, but they are very real to the person experiencing them. Nutritional factors should be considered as part of a careful, holistic assessment, especially for busy professionals whose performance is impacted.

Led by Dr Enam Abood, who has extensive experience in private general practice since 1998, this session reflects Harley Street Health Centre’s commitment to evidence-informed medicine and continuity of care. Whether you are seeking discreet sexual health screenings, comprehensive well-person checks, or predictable options for managing ongoing chronic conditions, our clinicians serve as your dedicated health advisors.
