If there is one recommendation I find myself returning to more than any other in clinic, it is this: establish a comprehensive baseline.

Not a standard check-up where results are compared against broad population averages. A more detailed assessment that looks at inflammatory markers, hormonal profile, metabolic function, and where appropriate, genetic predispositions.

The reasoning is straightforward. When you have a clearer picture of where your health stands today, every subsequent decision tends to be better informed.

In practice, I often see patients who have been told for years that their results fall within normal ranges. By the time they present in clinic, some of the earlier intervention windows may have narrowed.

This is not a reflection of anything being missed. Standard screening is designed to identify disease. Optimising health is a different objective, and it can benefit from a different approach.

A proper baseline gives you data. Data gives you options. And options, particularly when identified early, tend to be less involved and more effective.

It may not sound like dramatic advice. But in clinical experience, it is consistently among the most valuable.

If you would like to explore what a comprehensive health assessment involves, we are happy to walk you through it.

There are patterns we see regularly in patients whose biological age appears to have moved ahead of their chronological age.

These are five that come up often in clinical practice.

Persistent fatigue that does not seem to resolve with adequate rest. Recovery from minor soft tissue injuries taking longer than might be expected. Subtle cognitive changes such as reduced concentration or mental clarity. Skin quality shifts that seem disproportionate to age. Joint stiffness presenting earlier than is typical.

On their own, each of these can have straightforward explanations. When several present together, they may warrant a closer look.

What the research suggests is that biological ageing is not necessarily a fixed trajectory. It can be assessed through specific biomarkers, monitored over time, and in many cases responded to meaningfully when identified early.

The starting point is establishing a proper baseline. Understanding where you are today gives you the information to make considered decisions about what, if anything, may be helpful next.
If any of these feel familiar, it could be worth having a conversation with a practitioner who works in this space.

My honest thoughts on fasting, and why I no longer give a blanket recommendation either way.

The research does suggest that fasting can be beneficial for many people. It may support metabolic function, encourage the body to draw on energy reserves it would otherwise overlook, and has been associated with a reduction in chronic inflammation through processes like autophagy. There's also emerging evidence around its benefits for mental clarity and discipline.

That said, men and women can respond to fasting differently, and what works well for one person may not be the right fit for another. Individual factors including hormonal profile, activity levels, and overall health picture all play a role.

Rather than advising for or against it, my approach is to look at what the data shows for each individual and make decisions based on that, tracking how the body responds over time rather than applying a one-size-fits-all rule.

If you're considering fasting and want to understand whether it might be a good fit for you, it's worth having a proper conversation before starting.

Normal results don't always mean everything is fine. It's something I find myself explaining regularly in the clinic.

An individual can lose a meaningful amount of organ or joint function and still show results within the normal range. Standard testing was largely designed to identify disease once it's present, not to catch the gradual decline that can precede it.

In practice, the markers I find most useful to track are:

— Inflammatory markers: High-sensitivity tests can pick up low-grade chronic inflammation that standard panels may miss
— Metabolic health indicators: How your body processes glucose and insulin can offer early insight into metabolic function, often before symptoms appear
— Hormonal markers: Hormones influence almost every system in the body. Tracking them over time, rather than as a single snapshot, tends to give a much clearer picture

The goal isn't to run more tests. It's to run the right ones, at the right time, and to track them consistently enough to spot change early and act on it.

Save this before your next health check. It may be worth raising some of these with your clinician.

Patients ask me regularly about wellness trends and whether they're worth trying. It's a fair question, and the honest answer is that it depends on the individual and what the evidence currently suggests.

With so many options competing for attention, it can be hard to know what's genuinely worth exploring. Here's my measured take, with the caveat that individual response can vary significantly:

— Ice baths: ⭐⭐ — Some evidence for recovery, but benefits can be overstated for general use
— Cold showers: ⭐⭐ — Refreshing, but the research is still limited
— Red light therapy: ⭐⭐⭐⭐ — Growing evidence base, particularly for cellular recovery and inflammation
— Infrared saunas: ⭐⭐⭐⭐ — Promising data on cardiovascular and recovery benefits
— Wearables: ⭐⭐ — Useful for awareness, but data quality and clinical application vary widely
— Blue light glasses: ⭐⭐ — Evidence for meaningful benefit remains limited in most cases
— Grounding: ⭐⭐⭐ — Early research is interesting, though more robust studies are needed
— Breathwork: ⭐⭐⭐⭐ — Consistently well-supported for stress regulation and nervous system health
— Hyperbaric oxygen therapy: ⭐⭐⭐⭐ — Emerging evidence across several areas, particularly recovery and inflammation
— Cryotherapy: ⭐⭐⭐ — Some clinical applications show promise, though evidence for general wellness use is still developing

Most of these can play a role, depending on the individual and the context. The challenge is knowing which ones are worth prioritising for your specific situation.

Which of these have you tried? And which do you think deserves more attention?

The conversation around aesthetics is shifting, and for good reason.

For a long time, the default approach has been to mask or temporarily soften concerns.

There's a place for that. But a growing number of patients are now asking a different question: is there a way to actually improve what's happening beneath the surface, rather than simply managing how it looks?

That's the thinking behind regenerative medicine in aesthetics. Rather than working around the issue, the aim is to support the skin's own renewal processes, improving tissue quality, elasticity, and overall health in a way that tends to look and feel more natural over time.

At KYZN Clinic, our protocols are built around this approach. As one of the popular regenerative medicine practices for skin and hair loss, we've developed trademark techniques, stacked in a specific sequence, to support the best possible outcomes for each individual.

If you're curious about what a regenerative approach might look like for you, we'd be happy to talk it through. Book a consultation to explore your options: https://kyzn.collums.co.uk/

5 signs your joints may be telling you something worth paying attention to.

As a consultant orthopaedic surgeon, most of the patients I see with joint problems share one thing in common: they noticed something earlier and waited.

Here are five early signs that are worth taking seriously:

— Morning stiffness that lingers: If your joints take a while to get going after waking, this can be an early indicator of arthritis rather than something to simply push through
— Pain at rest or through the night: Discomfort that persists when you're not moving is worth investigating. It rarely resolves on its own
— Gradual loss of range of movement: If a joint isn't bending the way it used to, that change may be slow enough to go unnoticed until it becomes significant. Mobility lost over time can be difficult to fully recover
— New clicking or grinding: Some joint sounds are entirely normal. But if it's new and unfamiliar, it's worth having assessed
— Recurring swelling: Swelling that comes and goes but gradually becomes more frequent or persistent can be a sign that something is progressing

Around 90% of the patients I see present at a late stage. Catching these signs early opens up options that may not be available later.

If any of these sound familiar, it may be worth getting them looked at sooner rather than later. Feel free to get in touch or book a consultation if you'd like to talk it through: https://kyzn.collums.co.uk/

Can I be direct? Many people are still relying on blood tests that were designed primarily to identify existing disease — and that's a solid foundation.

But in my experience, there's often an opportunity to build on it.

Standard panels are genuinely valuable. They're good at telling you what's already wrong, and that matters. The question worth asking is what additional markers might add to that picture — particularly when it comes to what may be developing, rather than what's already present.

Here's what I think deserves more attention alongside standard testing in 2026:

— Cancer screening markers: Earlier detection can change outcomes significantly. Most people only investigate when symptoms appear
— High-sensitivity CRP: A useful complement to conventional inflammation markers, particularly for identifying low-grade chronic inflammation that may quietly contribute to cardiovascular and metabolic risk over time
— Comprehensive metabolic panels: A single glucose reading provides useful context, but trend data tends to tell a more complete story
— Gut health biomarkers: Often absent from standard testing, yet increasingly linked to immunity, mood, and energy
— Cardiovascular risk profiling: Cholesterol numbers are a valuable starting point — particle analysis can add another layer to the overall picture

The best time to run these additional tests is before you need them. Not as a replacement for standard care, but as a way of building a more complete view of where your health is heading.

Which of these markers have you had tested? And what would you most want to understand about your health if you could find out?

Not all exercise delivers the same results — and in my clinical experience, some approaches are consistently undervalued while others get more credit than they perhaps deserve.

Here's how I would rate the most popular approaches, based on what the evidence tends to show and what I see working in practice. As always, individual context shapes everything — these are observations, not fixed rules.

— HIIT (individualised): ⭐⭐⭐⭐⭐ Can be highly effective when designed around your specific needs
— HIIT (generic): ⭐⭐ May act more as a stressor than a stimulus for some people

— Zone 2 cardio: ⭐⭐⭐⭐⭐ Tends to be underappreciated relative to its long-term benefits

— Strength training (done correctly): ⭐⭐⭐⭐⭐ One of the higher-return investments in long-term health

— Stretching alone: ⭐⭐ Valuable in context, though limited as a standalone practice

— Daily steps: ⭐⭐⭐⭐ Often dismissed because of its simplicity, but the evidence is consistent

— Yoga (structured, purposeful): ⭐⭐⭐⭐ Can be genuinely valuable with the right guidance
— Yoga (casual, unsupervised): ⭐⭐ Benefits may be more limited without structure or intention

— Reformer Pilates: ⭐⭐⭐⭐ The reformer format tends to produce better outcomes for many people

— Passive rest alone: ⭐⭐ Rest matters, but recovery is more than simply doing nothing
— Optimised recovery (sleep + rest protocol): ⭐⭐⭐⭐⭐ Consistently one of the most impactful and underleveraged tools

The pattern I see clinically? The most effective programme is usually the one matched to your body, your goals, and your current capacity — not the one that's simply most popular.

Which of these surprised you? And what's the one form of exercise you've found most underappreciated?

Losing your hair? Here's what most men get wrong about why it's happening.

The uncomfortable truth is that hair loss isn't a single condition — it's a symptom. And the reason so many men spend years trying treatments that don't work is simple: they're treating the wrong cause.

In clinical practice, the three most common drivers I see are:

— Genetic sensitivity to DHT, which can gradually miniaturise follicles until the damage becomes difficult to reverse
— Nutritional deficiencies, with vitamin D being one of the most frequently overlooked
— Hormonal imbalance, which affects men far more often than most people realise, just differently to how it presents in women

The window for effective treatment is real. The earlier you identify what's actually driving the loss, the more options tend to be available.

A useful principle? A diagnosis should always come before a treatment plan, not the other way around.

What's one hair loss "solution" you tried that didn't deliver what it promised?

Not all wellness practices are created equal.

I just reviewed the research on popular health practices and their REAL impact. Here's my rating (1-5 scale):

-- High-protein diet: ⭐⭐⭐⭐⭐ (Strong evidence for supporting energy, muscle maintenance, and recovery)

-- 7-8 hours of quality sleep: ⭐⭐⭐⭐⭐ (Though individual needs vary based on age and circadian rhythms)

-- Basic hydration (2-3L water): ⭐⭐
-- Mineral-balanced hydration: ⭐⭐⭐⭐ (Electrolytes make a meaningful difference)

-- Evidence-based exercise: ⭐⭐⭐⭐⭐ (When matched to your goals and capacity)
-- Poorly programmed exercise: ⭐ (Can increase injury risk without benefit)

-- Sauna (20min, 3x weekly): ⭐⭐⭐ (Good evidence for cardiovascular benefits)
-- Cold therapy: ⭐⭐ (Emerging research, though benefits may be overstated)

-- Mindful meditation: ⭐⭐⭐⭐⭐ (Strong evidence for stress management and mental health)
-- "Detox" teas: ⭐ (Limited evidence to support most marketing claims)

The wellness industry often emphasises complexity over fundamentals. Prioritising protein intake, quality sleep, proper hydration, appropriate exercise, and stress management tends to yield the greatest returns.

What's your most valuable wellness practice? And which wellness trend have you tried that didn't deliver results for you?

Can I be honest? Here are 5 health biomarkers that deserve more nuanced understanding:

LDL cholesterol as a standalone number has limitations - research increasingly shows that LDL particle size and pattern provide important additional context that standard testing often misses.

HbA1c deserves more attention - it provides insight into average blood sugar over 2-3 months, offering a more comprehensive view of metabolic health than a single glucose reading.

High-sensitivity CRP can detect low-grade inflammation that conventional CRP testing may miss, making it valuable for assessing cardiovascular risk and systemic inflammation.

Cortisol measurement timing is critical - a single morning reading provides limited information compared to assessing your full diurnal rhythm throughout the day.

Testosterone plays important roles in mood, muscle mass, and cognitive function in both men and women, yet is often undertested relative to its potential clinical significance.

Which biomarker surprised you most? And what health markers do you think deserve more attention?
