Anaemia is one of the most common conditions affecting pregnant women worldwide, yet it is often underestimated.
Many women are told:
“Your iron is a bit low, just take supplements.”
But anaemia during pregnancy is not just about low iron, it can significantly affect both mother and baby if not properly managed.
This blog explains what anaemia is, why it happens in pregnancy, its impact, warning signs, and when it becomes a concern.
What Is Anaemia in Pregnancy?
Anaemia occurs when the body does not have enough healthy red blood cells to carry oxygen efficiently.
In pregnancy, this is most commonly due to iron deficiency, but can also involve:
- Folate deficiency
- Vitamin B12 deficiency
- Chronic illness
- Blood loss
Why Anaemia Is Common in Pregnancy
Pregnancy naturally increases demand on the body.
1. Increased Blood Volume
During pregnancy:
- Blood volume increases by up to 50%
- More iron is needed to produce red blood cells
If iron intake does not match this demand, anaemia develops.
2. Fetal Iron Needs
The baby depends entirely on the mother for iron to:
- Develop the brain
- Form blood
- Support growth
3. Dietary Gaps
Some women may not consume enough iron-rich foods due to:
- Nausea
- Food aversions
- Dietary restrictions
Types of Anaemia in Pregnancy
1. Iron Deficiency Anaemia
Iron Deficiency Anaemia
Most common type. Caused by insufficient iron intake or absorption.
2. Folate Deficiency Anaemia
Due to low folic acid, important for:
- Red blood cell formation
- Fetal neural tube development
3. Vitamin B12 Deficiency Anaemia
Affects:
- Nerve function
- Red blood cell production
Symptoms of Anaemia in Pregnancy
Common Symptoms
| Symptom | What It Feels Like |
|---|---|
| Fatigue | Constant tiredness even after rest |
| Dizziness | Light-headedness, especially when standing |
| Shortness of breath | Difficulty breathing during mild activity |
| Pale skin | Noticeable loss of colour |
| Headaches | Frequent or persistent |
| Palpitations | Racing heartbeat |
Normal Pregnancy vs Anaemia Symptoms
| Feature | Normal Pregnancy | Possible Anaemia |
|---|---|---|
| Fatigue | Mild to moderate | Severe and persistent |
| Breathlessness | With exertion | Even at rest |
| Dizziness | Occasional | Frequent |
| Energy levels | Fluctuating | Constantly low |
| Skin colour | Normal | Pale or dull |
Impact of Anaemia on the Mother
1. Severe Fatigue
Anaemia reduces oxygen delivery to tissues, causing:
- Exhaustion
- Weakness
- Reduced ability to perform daily activities
2. Increased Risk During Labour
Severe anaemia can lead to:
- Poor tolerance of blood loss
- Increased risk of complications
- Delayed recovery
3. Reduced Immunity
Women may become more prone to:
- Infections
- Slow healing
Impact on the Baby
1. Low Birth Weight
Insufficient oxygen and nutrients can affect growth.
2. Preterm Birth
Severe anaemia increases risk of early labour.
3. Developmental Concerns
Iron is essential for brain development.
When Anaemia Becomes Dangerous
Anaemia is considered severe when:
- Haemoglobin levels drop significantly
- Symptoms affect daily functioning
- There is poor response to supplements
Seek urgent care if:
- Fainting occurs
- Breathlessness becomes severe
- Heart rate is persistently high
Why Anaemia Is Often Missed
1. Symptoms Overlap With Normal Pregnancy
Fatigue and dizziness are often dismissed as “normal pregnancy symptoms.”
2. Slow Onset
Anaemia develops gradually, making it harder to notice.
3. Late Testing
Some women are only tested once or twice during pregnancy.
How Anaemia Is Diagnosed
Diagnosis is done through blood tests measuring:
- Haemoglobin levels
- Iron stores (ferritin)
- Red blood cell indices
Treatment of Anaemia in Pregnancy
1. Iron Supplements
- Oral iron tablets
- Liquid iron in some cases
2. Diet Improvement
Iron-rich foods include:
- Red meat
- Spinach
- Beans
- Fortified cereals
3. Vitamin Support
- Folic acid
- Vitamin B12 if needed
4. Severe Cases
May require:
- Iron infusions
- Close monitoring
Improving Iron Absorption
To improve absorption:
- Take iron with vitamin C
- Avoid tea or coffee around iron intake
- Take supplements as prescribed
Emotional Impact of Anaemia
Women with anaemia often feel:
- “Weak” or unable to function
- Frustrated by constant fatigue
- Anxious about pregnancy health
Understanding the cause helps restore reassurance:
This is a medical condition, not personal weakness.
Final Thoughts
Anaemia in pregnancy is common, but it should never be ignored.
Early detection and proper management can make a major difference in:
- Maternal wellbeing
- Pregnancy outcomes
- Baby’s development
Key Takeaway
- Anaemia reduces oxygen delivery in pregnancy
- It affects both mother and baby if untreated
- Early testing and treatment are essential
