Fatigue is one of the most common complaints in modern healthcare — yet it's also one of the most misunderstood. If you’ve been told your blood tests are “normal,” but you still feel exhausted, wired but tired, struggling to get through the day, or crashing in the afternoons, you’re not alone.

At Healixa Health, we take a functional medicine approach to fatigue — looking beyond surface symptoms to uncover the real reasons your energy is depleted. Fatigue isn’t just about needing more sleep or coffee — it’s your body’s way of telling you something deeper is out of balance.

Fatigue from a functional medicine perspective

Why am I so tired?

Fatigue can be caused by a range of underlying issues, often interacting in complex ways. Some of the most common contributors include:

Our processes

Rather than offering a quick fix, we dig deep to find the root cause — and build a personalised plan to restore your energy from the inside out.

  • We use advanced testing to investigate what’s driving your low energy, including:

    ◦ Comprehensive Thyroid Panel – TSH, free T3, free T4, reverse T3, and antibodies

    ◦Adrenal Stress and Cortisol Testing – to assess your stress response and daily energy rhythm

    ◦ DUTCH Hormone Testing – to evaluate oestrogen, progesterone, testosterone, DHEA, cortisol patterns, and hormone metabolism, especially if fatigue is linked to perimenopause or hormonal imbalance

    ◦ Organic Acids Test (OAT) – for insights into mitochondrial function, nutrient status, detoxification, and microbial balance

    ◦ Full Nutrient and Mineral Testing – iron, ferritin, B12, folate, vitamin D, magnesium, and more

    ◦ Advanced Stool Testing – to explore gut function, dysbiosis, and inflammation

    ◦ Inflammatory and Immune Markers – such as CRP, homocysteine, and white cell function

    ◦ Toxin and Heavy Metal Screening – where relevant

    ◦ Blood Sugar and Insulin Markers – to assess glycaemic control and fatigue related to energy crashes

    Each test is selected based on your unique history, symptoms, and health timeline.

  • Once we’ve identified the root causes of your fatigue, we design a personalised treatment plan that may include:

    ◦ Nutritional therapy to restore key nutrients and stabilise blood sugar

    ◦ Supplements to support mitochondria, adrenals, and thyroid function

    ◦ Nervous system support through breathwork, pacing, and stress reduction

    ◦ Gut and detox support if inflammation, leaky gut, or toxin overload are present

    ◦ Sleep optimisation strategies tailored to your circadian rhythm

    ◦ Gradual reintroduction of movement and exercise tolerance (if appropriate)

    Healing from chronic fatigue takes time, but it’s possible — with the right plan and consistent, compassionate support.
