India's National Family Health Survey (NFHS-5, 2019–21) found that 57% of women aged 15–49 were anemic — a figure that had risen from the previous survey. That is more than one in two. It is not caused by one thing but by six overlapping ones, and working out which apply to you is what turns a vague "eat more iron" into something that actually works.
The Six Causes
1. Menstrual blood loss
Every period costs iron. Heavy periods — medically, menorrhagia — cost a great deal.
Signs your periods are heavy enough to be the cause: soaking through a pad or tampon every hour or two, bleeding longer than 7 days, passing clots larger than a rupee coin, or needing to change protection during the night.
This is the most common cause of iron deficiency in Indian women, and it is the one most often dismissed — both by women themselves and sometimes by doctors. Heavy periods are not something to simply endure. Fibroids, adenomyosis, thyroid problems and PCOS all cause them, and all are treatable. If this is you, see a gynaecologist. No amount of dietary iron keeps up with ongoing heavy loss.
2. Vegetarian diet with poor absorption
Indian vegetarian diets contain iron — dal, greens, millets — but it is non-haem iron, absorbed poorly and easily blocked. Combined with chai at every meal, actual absorption can be a fraction of intake.

3. Repeated pregnancies with short gaps
Pregnancy takes a large amount of iron for the baby, the placenta and expanded blood volume. Breastfeeding continues the demand. Two pregnancies close together, without stores rebuilt in between, leaves many women in permanent deficit.
Ferritin takes 3–6 months to rebuild even with good intake. Recovery is slower than most people expect.
4. Eating last and least
This is uncomfortable to state but it is well documented in Indian nutrition research: in many households women eat after everyone else, and what remains. Less protein, less variety, smaller portions.
It is worth naming, because no supplement fixes a household pattern. If this is your situation, the change that matters is eating a proper meal yourself, not adding a powder to an inadequate one.
5. Undiagnosed conditions
- Thyroid disorders — common in Indian women and a cause of both anemia and heavy periods
- PCOS — irregular and sometimes heavy bleeding
- Coeliac disease — more common in India than once believed; unexplained iron deficiency is a classic sign
- Thalassaemia trait — genuinely common in some Indian communities. It looks like iron deficiency on a basic blood count but iron will not fix it, and taking iron unnecessarily is harmful. If your anemia never responds to iron, ask specifically about this.
- Intestinal parasites — hookworm remains a real cause in parts of India
6. B12 deficiency alongside
Many Indian women have both iron and B12 deficiency. Treating only the iron leaves half the problem. See Vitamin B12 for Vegetarians in India.
Why It Gets Missed
The symptoms — tiredness, breathlessness on stairs, hair fall, brittle nails, poor concentration, feeling cold, low mood — are exactly the things women are most often told to expect from ordinary life. Working, running a household, raising children. So it is normalised for years.
Persistent exhaustion is not a normal part of being a woman. It is a symptom, and it is usually measurable and treatable.
Two signs worth knowing because they are specific rather than vague:
- Pica — craving ice, chalk, mud, raw rice. A classic sign of significant iron deficiency.
- Restless legs at night — strongly associated with low ferritin.
What to Do
1. Get the right tests
Not just haemoglobin. Ask for ferritin (iron stores — falls first), a full blood count with red cell indices, vitamin B12, and TSH.
If your doctor says "your haemoglobin is fine" and you still feel exhausted, ask specifically for ferritin. Ferritin can be low with normal haemoglobin, and that state causes fatigue and hair loss on its own.
2. Address heavy periods if you have them
See a gynaecologist. This is the step that changes the outcome for many women, and it is the one most often skipped.
3. Fix absorption, not just intake
Vitamin C with every iron meal. Tea and coffee an hour away. Curd and milk two hours away. Soak and sprout dals. Cook in an iron kadhai.
See the full Indian diet plan.
4. Support it with food-based supplements
Hemoglobin Supplement Powder · Beetroot · Spirulina · Moringa — all taken with vitamin C, away from tea and dairy.
5. Retest at three months
Haemoglobin and ferritin. Do not judge by how you feel.
Frequently Asked Questions
What is a normal hemoglobin for women?
Generally 12–15 g/dL. Below 12 is anemia in non-pregnant women; below 11 in pregnancy. Your lab's reference range applies.
Can anemia be cured with diet alone?
Mild deficiency, often yes, with correct absorption. Moderate or severe anemia needs medical treatment and the cause found.
How long does it take to recover?
Haemoglobin responds in 4–8 weeks. Ferritin takes 3–6 months. Do not stop when haemoglobin normalises — the stores are still empty.
Why did my anemia come back?
Because the cause was not addressed — usually ongoing heavy periods. Treat the cause, not just the number.
Is anemia dangerous in pregnancy?
It is associated with preterm birth and low birth weight, which is why antenatal iron supplementation is standard in India. Take what you are prescribed.
