Why Am I Gaining Weight During Menopause?
One of the most common questions I hear from women attending my Metabolic Health Clinic in Biggleswade is: “I’m eating the same, exercising the same and yet I’m gaining weight. What has happened to my body?” For many women, the years leading into menopause can feel incredibly frustrating. Weight begins accumulating around the abdomen, sleep becomes more disrupted, energy levels become less predictable and the diet and exercise habits that worked for decades suddenly seem inef


High Blood Pressure: Why It Is Not Always Just a Numbers Problem
High blood pressure is often treated as though the body has simply malfunctioned. The usual pattern is familiar. One medication is prescribed. Then another is added. Then a third. The number is monitored, but the reason the pressure went up in the first place is rarely investigated in any meaningful depth. Persistently elevated blood pressure can increase the risk of stroke, heart disease, kidney disease and vascular damage. It should never be ignored. The issue is that blood


Menstrual Pain: Understanding What’s Really Driving Dysmenorrhoea
Menstrual pain is often dismissed as a normal part of being a woman. Whilst mild discomfort can occur as part of a healthy menstrual cycle, severe pain should never be considered something that simply has to be endured. Understanding what drives menstrual pain requires an appreciation of the menstrual cycle itself, the role of ovarian hormones, inflammatory mediators, the nervous system and the wider physiological factors that can influence symptoms. The Menstrual Cycle: More


Endometriosis: Looking Beyond Hormones
Endometriosis is often described as a hormonal condition, yet the reality is considerably more complex. It is a chronic inflammatory disorder involving the immune system, nervous system, microbiome, hormone signalling pathways and environmental influences. Whilst oestrogen plays a significant role, it represents only one piece of a much larger picture. Endometriosis is characterised by the presence of endometrial-like tissue outside the uterus. These lesions can be found on t


Iron and Anaemia: Why Iron Tablets Are Not Always the Answer
Iron deficiency is one of the most common nutritional problems worldwide, affecting more than 1.2 billion people. Yet many people are prescribed iron supplements without anyone asking a more important question: Why is the iron low in the first place? Iron deficiency can be caused by poor dietary intake, impaired absorption, chronic inflammation, infections, digestive disorders, heavy menstrual bleeding, pregnancy, endurance exercise, medications and chronic disease. Simply ta


PCOS: Understanding What Is Really Driving Polycystic Ovary Syndrome
Polycystic Ovary Syndrome (PCOS) is one of the most common endocrine conditions affecting women of reproductive age. Despite its prevalence, it remains one of the most misunderstood conditions in women’s health. Many women are told they have “cysts on their ovaries” and are prescribed hormonal contraception without ever being given a clear explanation of what is actually happening within the body. The reality is far more complex. PCOS is not simply an ovarian condition. It is


Autoimmune Disease: Looking Beyond Symptom Management
Autoimmune conditions affect millions of people worldwide and continue to rise in prevalence. Conditions such as Hashimoto’s thyroiditis, coeliac disease, rheumatoid arthritis, psoriasis, inflammatory bowel disease, lupus and multiple sclerosis are often viewed as separate illnesses affecting different organs and systems. Yet many share common underlying mechanisms involving immune dysregulation, chronic inflammation and environmental influences. For many people, receiving an


Anxiety and Nutrition: Why the Body Should Not Be Left Out of the Conversation
Anxiety is often treated as though it exists purely in the mind. For many people, the standard route is familiar. They speak to their GP, describe panic, worry, racing thoughts, poor sleep, tension or a constant sense of unease, and are offered medication or talking therapy. Those approaches may help some people, and in certain situations they can be important. What is often missed is the body. Anxiety is not always simply a psychological problem. It can also be a physiologic


Histamine Intolerance: Symptoms, Triggers and Why It Is Often Missed
Histamine is often associated with hay fever, allergies and itchy skin, but its role in the body is much wider than that. Histamine acts as a signalling molecule. It helps regulate immune responses, stomach acid production, brain alertness, blood vessel tone and inflammatory signalling. It is not inherently bad. We need histamine. The problem begins when the body is producing too much, releasing too much, or struggling to break it down efficiently. This is often referred to a


Hair Loss, Nutrition and Metabolic Health: What Your Hair May Be Telling You
Hair loss can be deeply distressing, especially when it seems to appear suddenly or when standard advice does not explain why it is happening. Many people are told that hair loss is simply genetic, hormonal or age-related. Sometimes that is true, but hair loss can also reflect wider changes in the body. Nutrient status, inflammation, stress, thyroid function, gut health, medication use and immune activity can all influence the hair growth cycle. Hair is not essential for surv


Why Weight Loss Is About More Than Calories
Many people trying to lose weight focus exclusively on calories. Whilst calorie intake does matter, it is only one part of the picture. The body is not a simple calculator. Food provides energy, but it also influences hormones, appetite, blood sugar regulation, satiety, metabolism and fat storage. This is one reason why two diets containing the same number of calories can produce very different results. Understanding Macronutrients The food we eat is made up of three main mac
