Common Causes of Persistent Fatigue and Tiredness

From AlFarabi Medical Labs | AlFarabi Medical Labs

Why are you always tired without exertion?

Do you have persistent tiredness or chronic fatigue without clear cause? Low energy and poor concentration may have physical or psychological causes needing careful assessment. This AlFarabi Medical Labs guide covers main possibilities.

1. Inactivity

Insufficient exercise weakens circulation and oxygen flow, reducing energy.

2. Mental stress and overthinking

Daily pressures exhaust the nervous system, causing common mental fatigue.

3. Dehydration

Even mild dehydration affects concentration and energy. Drink 8-10 glasses daily.

4. Chronic stress

Raised cortisol exhausts the body, worsens sleep, and causes daily fatigue.

5. Gland and hormone disorders

Thyroid dysfunction, low growth hormone, or excess cortisol may cause unexplained fatigue.

6. Anemia

A common medical cause, especially in women. Low iron or B12 affects oxygen transport.

7. Emotional exhaustion

Work or relationship pressures harm physical health and appear as chronic fatigue.

8. Emotional Eating

Eating in response to stress or anxiety causes blood sugar imbalance and sluggish episodes.

9. Sleep disorders

Poor or interrupted sleep reduces recovery ability, immunity, and activity.

🧪 When test for fatigue?

With unexplained fatigue over two weeks, or:

• Hair loss.
• Breathlessness.
• Palpitations.
• Poor memory or concentration.

A physical cause should be checked with comprehensive laboratory tests.

✅ Suggested tests:

• CBC, complete blood count.
• Vitamin D.
• Thyroid (TSH - T3 - T4).
• Iron and Ferritin.
• Vitamin B12 and folic acid.
• Liver and kidney function.

💡 AlFarabi Medical Labs advice:

Do not underestimate chronic fatigue. It may be an early sign needing treatment. Early tests prevent complications and support a more active, balanced life.
