Anaemia in Pakistan: Why Half of Pakistani Women Are Secretly Exhausted — Causes, Types, and What the Blood Test Really Shows

Anaemia — low haemoglobin, low red blood cell mass — affects an estimated 50–60% of Pakistani women of reproductive age and 45% of Pakistani children under five. It is the most common abnormal finding on a routine blood test in Pakistan. And yet it is also one of the most under-treated conditions in the country, because mild to moderate anaemia has been normalised — women are told they are "just tired" and sent home without investigation into the cause. This guide covers what anaemia actually does to the body, why it is so prevalent in Pakistan, and why treating the symptom without diagnosing the type is the most common mistake patients and doctors make.

What Anaemia Does to the Body — More Than Tiredness

Anaemia is a reduction in the oxygen-carrying capacity of the blood — either because there are fewer red blood cells, or because the red cells contain less haemoglobin than normal. Every cell in the body requires oxygen. When the delivery system is compromised, the effects ripple through every organ.

The symptoms of anaemia are so broad and non-specific that they overlap with stress, sleep deprivation, depression, thyroid disease, and a dozen other common conditions. This is precisely why a simple blood test — the CBC — is the only way to confirm or rule it out:

Why Pakistan Has Such Extreme Anaemia Rates

Pakistan's anaemia burden is not simply a matter of poverty — though poverty plays a role. It reflects specific, identifiable dietary, physiological, and healthcare patterns:

Dietary Iron Deficiency

Iron exists in food in two forms: haem iron (from red meat, found in high bioavailability) and non-haem iron (from lentils, spinach, found in lower bioavailability). Pakistan's rural population consumes relatively little red meat. Dal (lentils) is the primary protein source for much of the population — and while dal contains iron, the non-haem form is poorly absorbed, especially when consumed with tea, which contains tannins that further inhibit iron absorption.

Tea consumption in Pakistan is among the highest in the world. The habit of drinking chai with every meal — including meals containing iron-rich food — is one of the most consistent contributors to poor iron absorption in Pakistani adults and children.

Menstruation and Pregnancy Losses

Women of reproductive age lose iron every month through menstrual blood. In women with heavy periods — which affects a significant proportion of Pakistani women, often untreated — monthly iron losses can substantially exceed dietary iron intake. Multiple successive pregnancies with inadequate iron supplementation between them progressively deplete iron stores. Many Pakistani women enter their fourth or fifth decade with chronically depleted iron stores, not because they are eating badly but because the cumulative losses have exceeded the cumulative intake across decades of reproductive life.

Thalassaemia Carrier Prevalence

Pakistan has one of the highest thalassaemia carrier rates in the world — approximately 5–8% of the population carries a thalassaemia gene. Thalassaemia trait (being a carrier, not having the disease) causes a mild, persistent anaemia that can be misidentified as iron deficiency. This distinction is critical because treating thalassaemia trait anaemia with iron supplements is not just ineffective — it can cause harm through iron overload.

Gastrointestinal Blood Loss

Chronic blood loss from the gut — from peptic ulcers (extremely common in Pakistan, partly from H. pylori infection rates), hookworm infestation, or haemorrhoids — slowly depletes iron reserves over months to years. This cause is frequently overlooked when treating young men and older women with unexplained iron deficiency anaemia.

The Different Types of Anaemia — Why the Type Matters

This is the most important point in the entire guide: anaemia is a symptom, not a diagnosis. There are more than 20 different causes of anaemia, each requiring different treatment. Giving iron tablets to every anaemic patient — which is what happens routinely in Pakistani primary care — treats only one cause and misses (or harms) all the others.

Reading the CBC for Anaemia — The Key Numbers

A CBC gives several values that together identify not just whether anaemia is present, but what type it is. The key indices for anaemia classification:

• Haemoglobin (Hgb): The primary anaemia marker. Normal is above 12 g/dL for women and 13.5 g/dL for men. Any value below this is anaemia by definition, though severity ranges from borderline (11.5 g/dL) to severe (below 7 g/dL).
• MCV (Mean Corpuscular Volume): The average size of red blood cells. This is the most diagnostically powerful anaemia index. Low MCV (below 80 fL) = microcytic anaemia → iron deficiency or thalassaemia. High MCV (above 100 fL) = macrocytic anaemia → B12 or folate deficiency. Normal MCV with anaemia = normocytic → chronic disease, bleeding, or haemolysis.
• MCH (Mean Corpuscular Haemoglobin): How much haemoglobin each cell carries. Low in iron deficiency. Normal in thalassaemia trait despite low MCV — this is one of the distinguishing features.
• RBC count: Number of red cells. Iron deficiency has fewer but smaller cells. Thalassaemia trait has a normal or elevated RBC count with smaller cells — an important distinguishing pattern.
• RDW (Red Cell Distribution Width): Variation in cell size. High in iron deficiency (mixture of normal and depleted cells). Normal in thalassaemia trait (all cells are uniformly small).

Thalassaemia in Pakistan — What Every Family Should Know

Pakistan is one of the highest-burden countries for thalassaemia in the world. An estimated 5–8% of Pakistanis carry a beta-thalassaemia gene (thalassaemia trait). Carriers are healthy — they have mild anaemia that requires no treatment. But two carriers who have children together have a 25% chance of producing a child with beta-thalassaemia major — a severe, transfusion-dependent anaemia requiring monthly blood transfusions for life.

Pakistan sees an estimated 5,000–9,000 new births of thalassaemia major patients every year. Every one of these births was theoretically preventable through pre-marital thalassaemia screening of both partners.

The haemoglobin HPLC test — which identifies thalassaemia carriers definitively — is strongly recommended:

• For all couples before marriage or before first pregnancy
• For anyone with unexplained persistent mild anaemia that has not responded to iron treatment
• For anyone with a family history of thalassaemia, chronic anaemia, or "always pale" family members

Treatment by Anaemia Type — Why Getting the Diagnosis Right Matters

• Iron Deficiency Anaemia: Oral iron supplements (ferrous sulphate or ferrous gluconate) for 3–6 months — long enough to replenish stores, not just normalise haemoglobin. The source of deficiency must be identified: heavy periods (gynaeocological referral), gut bleeding (GI evaluation), dietary inadequacy (nutrition counselling). Taking iron with Vitamin C improves absorption. Taking iron with tea, milk, or antacids blocks absorption.
• B12 Deficiency: Intramuscular B12 injections for rapid correction, followed by oral supplements. B12 from diet is found only in animal products — strict vegetarians and the elderly with gastric atrophy are most affected. A critically important point: giving folic acid to a B12-deficient patient can mask the anaemia in blood tests while neurological damage continues silently. Always test both B12 and folate before treating macrocytic anaemia.
• Thalassaemia Trait: No treatment needed. No iron supplements unless iron deficiency is concurrently confirmed by ferritin testing. Genetic counselling for couples of reproductive age.
• Anaemia of Chronic Disease: Treatment of the underlying condition — kidney disease (with erythropoietin if needed), chronic infection, cancer. Iron supplementation is generally unhelpful and may worsen outcomes in some of these conditions.

Frequently Asked Questions

What haemoglobin level is dangerous in Pakistan?

Haemoglobin below 8 g/dL is considered severe anaemia and warrants urgent medical evaluation. Below 7 g/dL, most doctors recommend investigation for transfusion depending on symptoms and the underlying cause. Values between 8–11 g/dL are moderate anaemia — not immediately dangerous but requiring diagnosis and treatment. Values between 11–12 g/dL (women) or 11–13.5 g/dL (men) are mild anaemia — common, treatable, and important not to ignore.

Why doesn't my anaemia improve despite taking iron tablets for months?

Several possibilities: you may not have iron deficiency anaemia (thalassaemia trait, B12 deficiency, or chronic disease anaemia would not respond to iron); you may be taking the iron with tea, milk, or antacids that block absorption; the dose may be insufficient; there is ongoing blood loss exceeding the rate of replacement (heavy periods, gut bleeding). A ferritin test and CBC re-check will clarify whether iron stores are genuinely replenishing. If ferritin is normal or high despite ongoing low haemoglobin, the diagnosis needs to be reconsidered.

Can anaemia cause hair loss in Pakistani women?

Yes — specifically iron deficiency anaemia. Low ferritin (iron stores) is one of the most common causes of diffuse hair shedding (telogen effluvium) in Pakistani women, and it can cause hair loss even before haemoglobin falls to anaemic levels. A ferritin level below 30 ng/mL is associated with hair loss even in the presence of a "normal" CBC. Treating iron deficiency typically produces visible hair regrowth within 3–6 months.

Is anaemia during pregnancy dangerous in Pakistan?

Yes — significantly so. Anaemia in pregnancy is associated with preterm birth, low birth weight, maternal haemorrhage risk, and increased infant and maternal mortality. Pakistan's maternal anaemia rates are among the highest in Asia. All pregnant women in Pakistan should be tested for haemoglobin at the first antenatal visit and supplemented accordingly. Severe anaemia (Hgb below 8 g/dL) in pregnancy warrants urgent specialist management.
