    Your Concerns

    What Is It?

    Persistent fatigue is one of the most common reasons patients come to 23MD Longevity — and one of the most clinically interesting, because the cause is rarely a single thing. Thyroid function, iron and B12 status, vitamin D, sex hormones, cortisol regulation, mitochondrial function, and sleep architecture all contribute. The 360 Longevity consultation, led by Dr Martin Galy, investigates these as one continuous picture rather than as separate complaints. The plan that follows comes from what the bloodwork and history reveal.

    Common Causes

    What Could Be Causing It

    Hormonal

    Perimenopausal shifts, thyroid imbalance, post-pill stabilisation.

    Nutritional

    Iron deficiency, B12, vitamin D, magnesium.

    Sleep Architecture

    Disturbance not always visible to the patient; affects recovery profoundly.

    Mitochondrial Function

    Energy production at the cellular level.

    Cortisol Dysregulation

    Chronic stress changes the body's pattern of energy availability.

    Subclinical Infection or Inflammation

    Sometimes uncovered by bloodwork.

    FAQs

    Your Questions, Answered

    Persistent, unexplained fatigue — the kind that isn't resolved by a weekend of rest, isn't traceable to one obvious cause, and is affecting how you function day to day. Sudden onset, severe fatigue, or fatigue accompanied by other red-flag symptoms needs a GP first — 23MD will say so honestly.

    The Foundation Reset bloodwork is designed precisely to answer this. It looks at hormonal, metabolic, and nutritional drivers — and flags anything that warrants further investigation outside the clinic's scope.

    A full clinical history, a 4D longevity assessment (hormonal, metabolic, regenerative, lifestyle), bloodwork, and — within 24 hours — a written summary of the consultation and a treatment plan. Every patient gets a written summary; that's a 23MD standard.

    Depends on what's driving the picture. Nutritional deficiencies often correct in weeks; hormonal optimisation takes longer; mitochondrial and recovery work compound across months. The consultation will set honest expectations.

    If the fatigue is sudden, severe, or accompanied by other symptoms — yes. 23MD is not a substitute for primary care or specialist referral; the Foundation Reset is an investigative starting point, not an emergency assessment.
