🧭 What Is Anaemia?
Anaemia is a condition where the body does not have enough healthy red blood cells.
👉 Red blood cells carry oxygen around the body
👉 When levels are low, the body does not get enough oxygen
⚠️ Key Effect
- Leads to fatigue and low energy
- Can affect the whole body
🧩 Main Types Covered
🟥 1. Iron Deficiency Anaemia
🧬 What Happens?
- The body does not have enough iron
- Cannot make enough hemoglobin
🧾 Causes
- Blood loss (e.g. menstruation, ulcers)
- Poor diet (low iron intake)
- Poor absorption
🧠 Symptoms
- Extreme tiredness
- Weakness
- Pale skin
- Brittle nails
- Dizziness
🛠️ Treatment
- Iron supplements
-
Eating iron-rich foods:
- Red meat
- Leafy greens
- Beans and lentils
🟦 2. Vitamin B12 Deficiency Anaemia
🧬 What Happens?
- Lack of vitamin B12
- Red blood cells become large and abnormal (megaloblastic)
🧾 Causes
- Poor diet
- Lack of intrinsic factor (Pernicious anemia)
- Gastric surgery (e.g. bypass)
- Digestive conditions like Crohn’s disease
🧠 Symptoms
- Fatigue
- Pale skin
- Numbness or tingling (hands/feet)
- Muscle weakness
- Memory problems or confusion
🛠️ Treatment
- Vitamin B12 injections
- High-dose B12 supplements
⚖️ Key Differences
| Feature | Iron Deficiency | B12 Deficiency |
|---|---|---|
| Cause | Low iron | Low vitamin B12 |
| Red Blood Cells | Small | Large (abnormal) |
| Unique Symptoms | Brittle nails | Nerve symptoms (tingling) |
| Risk | Fatigue | Possible nerve damage |
🚨 Important Risks
-
Untreated B12 deficiency can cause:
- Permanent nerve damage
- Cognitive problems
🔍 Diagnosis
Doctors use:
- Blood tests (e.g. Complete Blood Count)
- Vitamin level testing
👉 Important:
- Always identify the type of anaemia before treatment
📊 Key Takeaways
✔ Anaemia reduces oxygen in the body
✔ Iron deficiency is the most common type
✔ B12 deficiency can affect the nervous system
✔ Both types are treatable with the right diagnosis
⚠️ Important Note
Do not start supplements without medical advice.
A healthcare professional should confirm the diagnosis first.
🧠 Teaching Tip
To support learners:
- Use a diagram showing oxygen transport in blood
- Compare normal vs abnormal red blood cells
- Include food examples for iron and B12
- Add symptom matching activities
