How Does Functional Medicine Work?
Functional medicine is a very structured and science-based way of looking at health. It focuses on why symptoms occur, not just what they are.
Dr Konrad Grosser is a consultant cardiologist and one of the very few interventional cardiologists in the UK certified by the Institute for Functional Medicine (IFM). For Dr Grosser, this approach is a natural extension of his clinical work – understanding the full picture of a patient’s health, not just isolated test results or diagnoses.
Here we’ll explain what functional medicine is and how it can deliver a highly effective, personalised treatment plan.
What is functional medicine?
Conventional medicine is highly effective in acute situations. If you’re having a heart attack, you want rapid, evidence-based intervention. That’s where cardiology excels.
Where things become more complex is in long-term, chronic conditions. Fatigue, metabolic dysfunction, cardiovascular risk, hormonal imbalance, digestive issues, and low-grade inflammation don’t always fit neatly into a single diagnosis.
Functional medicine takes a different approach. It looks at how systems interact over time, asking what underlying imbalances may be driving symptoms. At the core of functional medicine is the idea that the body works as an interconnected network. The cardiovascular system doesn’t operate in isolation from metabolism, hormones, the immune system, or the gut.
For example, insulin resistance can increase cardiovascular risk. Chronic inflammation can affect both vascular health and brain function, and gut health can influence immune regulation and even mood.
Instead of looking at each issue separately, functional medicine connects the dots.
How functional medicine works
Functional medicine involves more detailed, targeted testing. Standard blood tests are essential, but they’re primarily designed to diagnose established disease. With functional medicine, the focus is on identifying subtle changes in physiology that may indicate future risk.
This can include markers of insulin resistance such as fasting insulin and HOMA-IR, inflammatory markers, advanced lipid profiles, micronutrient status, and hormone balance. In some cases, the health of the gut or environmental exposures are also explored.
Biological age testing can also help assess whether the body is ageing at an expected rate, or whether underlying stressors may be accelerating that process.
Personalised, practical interventions
Once underlying patterns are identified, the focus shifts to intervention. This is where functional medicine becomes highly individual.
Two people with similar symptoms may receive very different recommendations depending on their metabolic health, inflammatory profile, lifestyle, and genetic predispositions.
Interventions often include targeted nutrition, exercise strategies, sleep optimisation, stress management, and where appropriate, supplementation or medical treatment. The goal is to support the body’s natural systems while reducing the factors driving dysfunction.
Prevention as a central focus
One of the biggest advantages of functional medicine is its emphasis on prevention. Rather than waiting for disease to develop, it identifies risk early and acts on it.
This is particularly relevant in cardiovascular health, where conditions such as atherosclerosis, hypertension, and metabolic syndrome can develop over many years before symptoms appear.
By identifying early imbalances, there is often a window to slow, stop, or even reverse progression.
A complete picture of your health
Functional medicine doesn’t replace conventional care. It combines the strengths of modern diagnostics and treatment, with a deeper exploration of root causes and long-term risk.
