Tired All the Time: A Comprehensive Guide to Chronic Fatigue

Fatigue (see our guide to chronic fatigue in Lagos) Is a Symptom, Not a Diagnosis

Being told "you're just stressed" or "it's the Lagos lifestyle" when you're exhausted beyond normal tiredness is not good medical care. Persistent fatigue — the kind that sleep doesn't fix, that limits your function, and that has lasted weeks or months — has identifiable, treatable causes in the vast majority of cases. FXMed's systematic approach finds them.

The 10 Most Common Medical Causes of Chronic Fatigue

FXMed tip: If any of this sounds familiar, our Immune Support Programme may be exactly what you need. Book a free assessment to find out where your health stands today.

1. Hypothyroid (see our hormones guide)ism — the thyroid regulates metabolic rate; even subclinical low thyroid causes profound fatigue
2. Iron deficiency anaemia — reduces oxygen delivery to every cell; fatigue is the cardinal symptom
3. Vitamin B12 deficiency — impairs energy metabolism at the cellular level; neurological symptoms often accompany
4. Vitamin D deficiency — pervasive fatigue and muscle weakness; frequently found even in Lagos despite sunshine
5. Sleep apnoea — interrupted night breathing causes non-restorative sleep; the person feels they slept but wakes exhausted
6. Diabetes and blood sugar dysregulation — energy crashes from poor glucose control cause profound fatigue
7. Adrenal dysfunction / HPA axis dysregulation — chronic stress burns out the cortisol system; morning fatigue with afternoon energy is a classic pattern
8. Depression — physical fatigue is the most common physical symptom of depression in Nigeria
9. Chronic infection — hepatitis B, HIV, EBV, and chronic bacterial infections cause persistent fatigue
10. Heart disease — reduced cardiac output causes fatigue with minimal exertion

FXMed's Fatigue Investigation

Our comprehensive fatigue panel covers all major treatable causes: full thyroid, iron studies, B12, folate, vitamin D, HbA1c, full blood count, liver function, kidney function, CRP, and cortisol. For those with sleep symptoms, we facilitate sleep study referral. One comprehensive assessment — not years of "come back if it doesn't improve."
