Feeling tired all the time? Discover hidden medical and functional causes of fatigue, plus how testing like GI Map and HTMA can help restore your energy.

Do you feel constantly tired despite sleeping well and eating right? You’re not alone. Fatigue is one of the most common complaints people bring to their healthcare provider. While occasional tiredness may result from stress or lack of sleep, ongoing fatigue could indicate an underlying medical or functional imbalance that needs deeper investigation.
Common Medical Causes of Persistent Fatigue
If you’re always feeling drained, it’s important to consider potential underlying health conditions. Common medical causes include:
- Thyroid dysfunction (such as hypothyroidism)
- Iron deficiency or anemia
- Vitamin B12 or D deficiency
- Chronic infections
- Blood sugar imbalances or diabetes
- Cardiovascular or respiratory issues
- Autoimmune conditions (e.g., lupus, rheumatoid arthritis)
- Mental health conditions like depression or anxiety
Consulting your GP is a vital first step. They can rule out or diagnose these issues using standard medical evaluations and blood work.
When “Normal” Lab Results Don’t Explain Your Fatigue

Sometimes, your GP may tell you everything looks “normal,” yet your energy levels remain low. This is where a functional health approach can provide greater insight.
As a Nurse and Certified GI Map Practitioner, I use advanced diagnostic testing to uncover subtle imbalances often missed in conventional assessments.
How I Can Help Identify the Root Causes of Fatigue
Through a functional lens, I offer personalised wellness support that includes the following in-depth tests:
Functional Lab Testing Options:
GI Map Testing
A comprehensive stool test that evaluates gut health, including dysbiosis, inflammation, and infections. Gut imbalances are commonly linked to low energy, poor immunity, and mood fluctuations.
Hair Tissue Mineral Analysis (HTMA)
This test provides insight into your mineral levels, adrenal function, and toxic metal exposure—key factors in energy production and stress response.
Food Intolerance Testing
Identifies hidden food sensitivities that can cause inflammation, immune stress, and energy crashes—often without obvious digestive symptoms.
Hormonal and Stress Profile Testing
Assesses cortisol and other hormone levels to evaluate your body’s stress response and energy rhythm throughout the day.
Signs Your Fatigue May Be Functional in Nature
- Persistent fatigue with “normal” lab results
- Daily brain fog or poor focus
- Dependency on caffeine to get through the day
- Difficulty falling asleep or waking up refreshed
- Energy crashes after meals or light physical activity
Personalised Strategies That Support Long-Term Energy

In addition to testing, I provide holistic wellness guidance designed to support natural energy restoration, including:
- Nutritional advice based on your test results
- Gut-healing and detoxification support
- Homeopathic and nervous system-regulating therapies (e.g., breathwork, EFT)
- Mineral replenishment through food and supplementation
- Lifestyle changes that promote better sleep, energy, and resilience
Working With Both Your GP and a Holistic Practitioner
Persistent fatigue deserves a collaborative approach. Your GP is essential for ruling out serious or acute health conditions. However, if you’re still not feeling well despite normal test results, functional testing can offer deeper insights and solutions.
Combining conventional medical care with functional testing allows you to fully explore the root causes and build a sustainable path to recovery.
