Iron Deficiency Anaemia in Indian Women: Signs, Tests and Treatment
Why more than half of Indian women are anaemic, the symptoms beyond tiredness, how to read haemoglobin and ferritin, and how to take iron tablets so they actually work.
Key takeaways
- About 57 percent of Indian women aged 15 to 49 are anaemic according to NFHS-5, and iron deficiency is the commonest cause.
- Symptoms go beyond tiredness: breathlessness on stairs, hair fall, brittle nails, poor concentration, restless legs and cravings for ice or mud.
- Haemoglobin below 12 g/dL in non-pregnant women indicates anaemia. A low ferritin confirms that iron stores are empty.
- Iron tablets work best taken once a day or on alternate days, away from tea and coffee, and continued for about three months after haemoglobin normalises.
More than half of Indian women are anaemic. The fifth National Family Health Survey found anaemia in 57 percent of women aged 15 to 49, up from 53 percent five years earlier. Most of it is iron deficiency, and most of it is treatable with inexpensive tablets. Yet it is routinely dismissed as normal tiredness, stress or “weakness”. This guide explains how to recognise it, read the reports, and treat it properly.
Quick answer
Anaemia in women means haemoglobin below 12 g/dL, or below 11 in pregnancy. Iron deficiency is the commonest cause in India, mostly from heavy periods, pregnancy and low dietary iron. Ferritin confirms it. Iron tablets taken once daily or on alternate days, away from tea and coffee, usually raise haemoglobin within a month; continue about three months after it normalises.
Symptoms beyond tiredness
Tiredness and breathlessness climbing stairs are the classic signs. Others are easy to miss: hair fall, brittle or spoon-shaped nails, pale inner eyelids, poor concentration, headaches, cold hands and feet, a fast heartbeat, restless legs at night, and pica, a craving for ice, chalk, mud or raw rice. Many women live with these for years, assuming they are normal. They are not.
Why Indian women are at such high risk
Monthly blood loss, especially with heavy periods; repeated pregnancies and breastfeeding; a largely vegetarian diet in which iron is less easily absorbed; tea with meals, which blocks absorption; intestinal worms in some areas; and, less often, coeliac disease or blood loss from the gut. Heavy periods themselves deserve attention: soaking a pad every one to two hours, passing large clots, or periods lasting over seven days are worth reporting to a doctor.
Reading the reports
| Test | Typical finding in iron deficiency | What it tells you |
|---|---|---|
| Haemoglobin (Hb) | Below 12 g/dL (11 in pregnancy) | Confirms anaemia and its severity |
| MCV | Low (small red cells) | Points to iron deficiency or thalassaemia trait |
| RDW | High | Red cells of mixed sizes, typical of iron deficiency |
| Ferritin | Below 15 to 30 ng/mL | Confirms empty iron stores |
| Serum iron, TIBC, transferrin saturation | Low iron, high TIBC, low saturation | Supports the diagnosis when ferritin is unclear |
A low MCV with a normal ferritin and a high red cell count may be thalassaemia trait rather than iron deficiency; iron tablets do not help it, and it matters for family planning. The CBC guide explains these values in detail.
How to take iron so it works
Practical rules for iron tablets
Take one tablet a day or on alternate days, as prescribed, in the morning. Take it with water or a vitamin C source, not with tea, coffee, milk or calcium, and keep those an hour away. Expect dark stools; constipation and nausea are common and usually improve with a lower dose or alternate-day dosing. Keep tablets away from children, since iron overdose is dangerous.
Recent research shows the body absorbs iron better when doses are not crowded together, so once daily or alternate days is now preferred over several doses a day. Recheck haemoglobin after about four weeks. Intravenous iron is an option when tablets are not tolerated, not working, or when anaemia is severe, including in later pregnancy.
Eating to keep iron up
Good sources include eggs, fish, chicken and meat; dal, rajma, chana and soy; green leafy vegetables such as spinach, methi and amaranth; jaggery, dates and dry fruits; and fortified flour and rice. Pair plant sources with lemon, amla, tomato or citrus, and keep tea for between meals.
When to see a doctor
See a doctor for haemoglobin below 12 g/dL, symptoms of anaemia, heavy periods, anaemia in pregnancy, or anaemia that does not improve after a month of tablets. Anaemia in men or in women after menopause always needs a search for the cause, including blood loss from the gut. Severe breathlessness, chest pain or fainting needs urgent care.
Frequently asked questions
What is the normal haemoglobin level for women?
The WHO defines anaemia in non-pregnant women as haemoglobin below 12 g/dL, and in pregnant women below 11 g/dL. Many laboratories print a reference range of about 12 to 15 g/dL for women.
What is a normal ferritin level?
Ferritin reflects iron stores. Below about 15 ng/mL confirms iron deficiency, and many doctors treat symptoms when it is below about 30 ng/mL. Ferritin rises with infection and inflammation, so a normal value during an illness can hide low stores.
What is the best time to take iron tablets?
On an empty stomach or with a little food if it upsets you, ideally in the morning, with water or a vitamin C source such as orange or lemon water. Avoid tea, coffee, milk and calcium within an hour either side. Taking iron once daily or on alternate days is absorbed as well as, and tolerated better than, several doses a day.
How long does it take for iron tablets to work?
Energy often improves in a few weeks, and haemoglobin should rise by about 1 to 2 g/dL within four weeks. Treatment usually continues for about three months after haemoglobin is normal to refill iron stores. If haemoglobin does not rise, the doctor looks for absorption problems or ongoing blood loss.
Can I fix iron deficiency with diet alone?
Diet prevents deficiency but rarely corrects an established one quickly. Iron from meat, fish and eggs is absorbed best; plant iron from dal, rajma, chana, green leafy vegetables, jaggery and fortified foods is absorbed better with vitamin C. Most anaemic women need tablets for a period, then diet keeps levels up.
