PMOS (Polyendocrine Metabolic Ovarian Syndrome), a Functional Approach.

Polyendocrine Metabolic Ovarian Syndrome (PMOS) is the newly defined term for the condition previously known as Polycystic Ovary Syndrome (PCOS), following a global consensus published in The Lancet in May 2026. The updated terminology reflects a broader and more accurate understanding of the condition as a complex, multisystem disorder, rather than an isolated ovarian condition. The previous term ‘PCOS’ has been recognised as misleading, as it implies the presence of ovarian cysts, which are...

Thyroid Health Through a Whole‑Systems Lens

Thyroid health through a whole‑systems lens The thyroid gland may be small, like a butterfly tucked in the neck, but it packs a punch in keeping you energised, at a healthy weight, and feeling good overall. When it works right, you barely notice it. But if it’s underactive (hypofunction) or overactive (hyperfunction), life can feel out of whack. In this blog, we will break it down simply: what it does, common issues such as hypo and hyper thyroid, factors that can influence it and practical...

Skin, Hair & Nails: Beauty From Within

Glowing skin, strong, healthy hair and resilient nails are often seen as cosmetic goals, something to be fixed externally. Yet these tissues are among the fastest renewing in the body, making them especially sensitive to nutrition, digestion, hormone balance, stress and sleep. Hair follicles and nail-forming cells require a constant supply of nutrients, oxygen and hydration. When internal systems are under strain, changes in hair texture, shedding or brittle nails often appear alongside...

Nutritional strategies to support seasonal allergy symptoms

Seasonal allergies are no longer a minor inconvenience for a small subset of the population. Allergic rhinitis, more commonly known as hay fever, now affects a substantial proportion of adults and children in the UK, with prevalence continuing to rise year on year. In recent research around 49% of people reported suffering with hay fever symptoms.[i] Beyond the familiar sneezing, itchy eyes and nasal congestion, hay fever is associated with poor sleep, daytime fatigue, reduced concentration and impaired...

How Chronic Stress Disrupts Cortisol, Immunity & Energy And How to Restore Balance Naturally

Stress is often thought of as something that comes purely from a busy lifestyle, emotional pressure, or mental overload. While these are common triggers, stress on the body is far broader than emotional strain alone. The nervous system responds to many different challenges as stress, including psychological trauma, unresolved emotional experiences, acute or chronic infections, inflammation, blood sugar instability, poor sleep, over exercising, nutritional deficiencies, environmental exposures...

Key nutrients to support immunity during measles in the UK

Measles: What it is and how nutritional status influences outcomes What is measles? Measles (rubeola) is a highly contagious viral infection caused by the measles virus (a morbillivirus). It spreads through airborne droplets when an infected person coughs or sneezes and can remain infectious in the air for up to two hours after exposure. After infection, the virus initially affects the respiratory tract and then spreads systemically. Symptoms typically appear 7-14 days after exposure...

Understanding Inflammatory Bowel Disease (IBD): Causes, symptoms and support

Inflammatory bowel disease (IBD) is an umbrella term for chronic, immune-mediated conditions that cause ongoing inflammation in the digestive tract. The two main forms are: Crohn’s disease, which can affect any part of the digestive tract from mouth to anus. Ulcerative colitis, which primarily affects the colon and rectum. Unlike functional gut disorders such as IBS, IBD causes visible inflammation and tissue damage, which can be seen on imaging or during a colonoscopy. Symptoms often...

Endometriosis and functional medicine: Evidence‑informed insights for clinical practice

Endometriosis affects approximately 10–15% of women of reproductive age and remains one of the most challenging chronic inflammatory conditions encountered in women’s health practice. Characterised by the presence of endometrial-like tissue outside the uterine cavity, it is an oestrogen-dependent, immune-modulated and inflammatory disorder associated with chronic pelvic pain, infertility and significant quality-of-life burden. Although conventional management, including...

Cognitive longevity - a systems approach to healthy brain ageing

As longevity increases, cognitive healthspan has become a defining clinical challenge. While neurodegenerative conditions remain multifactorial and complex, converging evidence suggests that cognitive decline is not an inevitable consequence of ageing, but rather the cumulative outcome of modifiable metabolic, inflammatory, vascular and lifestyle inputs. A systems-based approach, integrating nutrition, sleep biology, movement, stress physiology and targeted nutraceutical support, provides a powerful...

The health benefits of dry January - Why taking a break from alcohol matters

As we head into January, many people choose to close the door on alcohol for a month, taking a break to prioritise their health and wellbeing. This ‘time out’ has become a popular way to reset after the festive season and reflect on personal habits. Alcohol consumption is widespread across the world, and in the UK alone, it’s estimated that around 80% of adults drink alcohol (alcoholchange.org.uk). Alcohol is deeply ingrained in many cultures, yet its physiological impact is profound. Beyond the...
