Prevention and key biomarkers for your longevity

In today's medical landscape, significant resources are devoted to treating disease. However, true health stems from identifying imbalances before they escalate into problems.
Did you know? 80% of type 2 diabetes, up to 90% of heart disease, and 30–90% of cancers are linked to lifestyle and environmental factors and are therefore preventable (Sources: CDC, WHO, WHO/IARC).
But before we dig into this topic, remember: prevention doesn’t mean restrictions, it means building resilience everyday!
Regular check-ups with key biomarkers (see detailed list below)
Prevention is not guessing, it’s measuring. Blood work acts like a dashboard, showing early imbalances long before symptoms appear. Think of it as a personalized “report card”: fasting glucose creeping up? Inflammation markers rising? Vitamin D too low? Theses subtle signals are the body whispering before it screams.
Aim for an annual or bi-annual panel
Track over time. Trends matter more than single values.
Listen to your body, connect to your sensations. Lab values are one side of the story. The other is listening inward: are you often tired in the afternoon? Possible blood sugar dysregulation. Do you have cravings all the time? Is your tolerance to stress lower? Potential adrenal fatigue. Is your sleep broken at 2-3am? Possible liver weakness.
Lifestyle as daily medicine:
Nutrition: focus on whole, anti-inflammatory foods with broad variety
Social connection: loneliness is a stronger risk factor for early mortality than obesity
Movement: every day! 10K steps. Walking, stretching, mobility throughout the day
Stress balance: short daily practice: (breathwork, medidation, journaling, being in nature)
Sleep hygiene: regular sleep-wake rhythm, no screen before bedtime, daylight in the morning to support circadian rhythm
Now let's look at these biomarkers!
Metabolic health: HbA1C, fasting glucose, fasting insulin, HOMA (insulin resistance), Tryglicerides, HDL, Ratio: TG/HDL, Vitamin D.
Inflammation: Ultra sensitive CRP, CRP, homocysteine, iron (+ full panel with: transferrin, transferrin saturation coefficient (TSC), ferritin)
Cardiac health: ApoB, lipoporetein (a), omega 3 index, oxidised-LDL, glycated LDL, HDL
Microbiome analysis (the type of test will depend on your symptoms)
Oxydative stress analysis (eventually)
Hormonal health: morning cortisol or even better 24h cortisol, DHEA-S, oestrogen, progesterone, total and free testosterone, LH, FSH, Prolactin, SHBG, AMH, estradiol
Full Thyroid checkup: TSH, free T3 & T3, reverse T3, Antibodies + co-factors listed in nutrients above.
Nutrients: Vitamins C, E, D, A, B6, B2, B9, B12, magnesium, selenium, zinc, potassium, calcium, phosphorus, Co-enzyme Q10 (key to mitochondria)
Liver and kidney function: ALT, AST, GGT, ALP, creatine & BUN, Uric Acid, eGFR
What matters is how these markers interact, what trends they show over time, and how they relate to your personal history, lifestyle and symptoms. And remember that the numbers on a lab report do not tell the whole story. 'Normal' lab ranges don’t mean “optimal”.You need to consider them in the context of your overall health (mental and physical).
