Possible causes
- 01
Iron deficiency anaemia
commonReduced red blood cell count or low iron stores limit oxygen transport, leading to persistent physical fatigue and weakness.
Evidence
- NICE CKS: Anaemia - iron deficiency (2021)
- 02
Hypothyroidism
commonAn underactive thyroid gland slows down the body's metabolism, commonly presenting as fatigue, weight gain, and cold sensitivity.
Evidence
- NICE CKS: Thyroid dysfunction - active management (2023)
- 03
Vitamin D deficiency
commonExtremely prevalent in Dubai due to sun avoidance; low levels are strongly linked to chronic fatigue, bone pain, and muscle weakness.
Evidence
- Mayo Clinic: Vitamin D deficiency symptoms and treatment (2023)
- 04
Type 2 diabetes or prediabetes
possibleInefficient glucose uptake by body cells due to insulin resistance leads to persistent systemic energy depletion.
Recommended tests
Full body blood test
→80+ marker screen — CBC, thyroid, liver, kidney, iron, vitamin D, HbA1c, lipids, hormones.
Why: Provides a comprehensive baseline screening for anaemia, thyroid function, metabolic health, and key vitamin deficiencies.
Guideline
- NHS: Common blood tests (2023)
Thyroid function panel
→TSH, Free T3, Free T4 — first-line test for fatigue, weight change, hair loss, mood.
Why: Directly evaluates TSH and free thyroid hormones to rule out hypothyroidism as a primary driver of low energy.
Guideline
- NICE: Thyroid disease assessment (NG145)
Iron & ferritin
→Ferritin, serum iron, TIBC — checks for iron-deficiency anaemia.
Why: Assesses iron stores to identify iron deficiency with or without anaemia, a frequent cause of fatigue.
GP consultation
→30–60 minute consultation with a British-trained GP — clinic, home or video.
Why: A detailed clinical consultation helps contextualise test results, explore lifestyle factors, and rule out complex causes.
Guideline
- RCGP: Clinical guidance on fatigue (2022)
When to worry
- Unexplained or unintentional weight loss
- Fever, night sweats, or swollen lymph nodes
- Shortness of breath or chest pain during mild exertion
- Sudden onset of severe muscle weakness or neurological changes
- New or worsening low mood, feelings of hopelessness, or self-harm thoughts

Is this AI symptom checker a diagnosis?+
No. It's a triage tool that suggests possible causes and the tests that would help narrow them down. Every real diagnosis and prescription at Aafiyah is made by a British-trained GP after a proper consultation.
Is it safe to describe my symptoms here?+
Yes. Your symptom text is used to fetch triage information and stored anonymously as a shareable page. No personal or medical details (name, ID, contact) are attached.
What if I might be having an emergency?+
If you describe red-flag symptoms — chest pain, stroke signs, severe breathing difficulty, heavy bleeding, anaphylaxis or suicidal thoughts — the result page shows an urgent-care banner. Call 999 or go to the nearest emergency department immediately.
How accurate is the AI?+
It's trained on public clinical patterns and is useful for common symptom clusters. It is not perfect and it does not replace a doctor — treat it as a well-read friend, not a physician.
Can I book a GP after seeing my result?+
Yes — every result page has a WhatsApp button pre-filled with your symptom summary and the suggested tests, so our reception can book you in with the right prep in place.
