Blood disorders in children range from very common and easily treated (like iron-deficiency anemia) to inherited conditions with significant implications for family planning (like thalassemia). Understanding the basics helps parents recognise when testing is worthwhile and what results might mean.
Iron-Deficiency Anemia
Iron-deficiency anemia is one of the most common nutritional issues in childhood. It happens when the body doesn't have enough iron to produce adequate hemoglobin, the protein in red blood cells that carries oxygen. It's especially common:
- Between 6 months and 3 years, when rapid growth increases iron needs
- In children with diets low in iron-rich foods, or high in cow's milk (which can reduce iron absorption and displace iron-rich foods)
- In adolescent girls after starting menstruation
- In babies born prematurely or at low birth weight (see our low birth weight guide)
Signs of Iron-Deficiency Anemia
- Pale skin, especially noticeable in the lower eyelids, lips, or nail beds
- Fatigue, irritability, or reduced activity levels
- Poor appetite
- In some cases, unusual cravings to eat non-food items (pica), such as ice or dirt
- Restless legs disrupting sleep (see our guide on sleep disorders in children)
Treatment
Usually involves dietary changes (iron-rich foods: red meat, chicken, fish, lentils, beans, fortified cereals, leafy greens — paired with vitamin C-rich foods to improve absorption) and, if levels are low enough, iron supplements prescribed by a doctor. Follow-up testing confirms improvement.
Thalassemia
Thalassemia is an inherited condition affecting hemoglobin production, causing varying degrees of anemia depending on the type. Pakistan has one of the highest carrier rates of thalassemia in the world — an estimated significant percentage of the population carries the thalassemia trait, often without knowing it (thalassemia "minor" or "trait" usually causes no symptoms).
Thalassemia major, which occurs when a child inherits the affected gene from both parents, causes severe anemia from infancy and requires lifelong regular blood transfusions and specialised care.
Why Screening Matters
Because thalassemia trait usually causes no symptoms, many carriers don't know their status. Simple blood tests (often a CBC followed by hemoglobin electrophoresis if needed) can identify carriers. Pre-marital or pre-pregnancy screening of couples allows informed decisions and, where both partners are carriers, options for early diagnosis during pregnancy or planning for specialised newborn care.
Bleeding & Clotting Disorders
Less common than anemia, but worth recognising. Signs that may warrant evaluation include:
- Frequent or severe nosebleeds
- Bruising that's frequent, large, occurs without clear cause, or appears in unusual locations (back, abdomen, chest)
- Prolonged bleeding from minor cuts, dental procedures, or after circumcision
- Heavy menstrual bleeding in adolescent girls
- Family history of a known bleeding disorder (such as hemophilia or von Willebrand disease)

Diagnosis: The Complete Blood Count (CBC)
A CBC is usually the first test ordered when a blood problem is suspected. It measures:
- Hemoglobin & hematocrit — the main indicators of anemia
- Red blood cell size and shape (MCV, etc.) — helps differentiate causes of anemia (e.g., iron deficiency tends to produce smaller red cells, which also overlaps with thalassemia trait — further testing distinguishes between them)
- White blood cells — can indicate infection or other conditions
- Platelets — relevant to clotting and bleeding tendencies
Depending on CBC results, further tests (iron studies, hemoglobin electrophoresis, clotting studies) may be recommended.
Prevention & General Tips
- Include iron-rich foods regularly from the time solids are introduced
- Limit cow's milk to recommended amounts (excessive intake is linked to lower iron levels in toddlers)
- Pair iron-rich foods with vitamin C sources (citrus, tomatoes, peppers) to boost absorption
- Consider thalassemia carrier screening for couples planning a family, especially with a family history
- Routine blood tests at well-child visits can catch issues early, even before symptoms appear
