What is Iron deficiency anaemia?
Iron deficiency anaemia happens when the body does not have enough iron to make haemoglobin, the part of red blood cells that carries oxygen. With less oxygen reaching tissues, you may feel tired, weak and breathless.
Women are more likely to develop it because of blood loss during periods and the extra iron needed during pregnancy. Anaemia is a common health problem worldwide, including in India, and it often goes unnoticed for a long time.
Symptoms depend on how low your iron is and how quickly it has dropped. Mild anaemia may cause no obvious symptoms, while more severe anaemia can affect daily life, concentration and work.
Common symptoms of Iron deficiency anaemia
Tiredness and lack of energy
Feeling exhausted or weak, even after a good night’s sleep, is the most common sign.
Shortness of breath
Getting breathless more easily than usual when climbing stairs or walking briskly.
Pale skin
Skin, the inside of the lower eyelids, lips or nail beds may look paler than normal.
Heart palpitations
Noticing a fast, pounding or fluttering heartbeat, especially with activity.
Headaches and dizziness
Frequent headaches or feeling light-headed can happen when less oxygen reaches the brain.
Hair loss
Hair may shed more than usual or feel thinner.
Cravings for non-food items
Craving ice, clay, chalk or raw rice (pica) can be a sign of low iron.
Brittle or spoon-shaped nails
Nails may break easily or become thin and curve upwards at the edges.
Sore tongue or mouth
A sore or smooth tongue, or painful cracks at the corners of the mouth.
Restless legs
An uncomfortable urge to move the legs, often at night.
What can cause Iron deficiency anaemia?
- Heavy or prolonged periods are one of the most common causes in women of reproductive age.
- Pregnancy increases the body’s need for iron to support the growing baby and extra blood volume.
- Diets low in iron, or plant-based meals without foods that help absorption, can lead to low iron over time.
- Conditions that reduce iron absorption, such as coeliac disease or some stomach surgeries, can cause deficiency.
- Blood loss from the stomach or bowel, for example from ulcers or regular use of some painkillers, can cause anaemia.
- Intestinal worm infections, which are more common in some settings, can contribute to iron loss.
How is Iron deficiency anaemia diagnosed?
A doctor usually checks for iron deficiency anaemia with a complete blood count (CBC), which measures haemoglobin and the size of red blood cells. A ferritin test shows how much iron is stored in the body. Because anaemia is a sign rather than a diagnosis on its own, your doctor may also ask about your periods, diet, pregnancy and bowel habits, and may suggest further tests to find the cause.
When to see a doctor
See a doctor if you feel tired and breathless for more than a few weeks, notice pale skin or palpitations, or have heavy periods. A simple blood test can show whether you have anaemia and what type it is. Do not start iron tablets on your own, as the cause needs to be found first and too much iron can be harmful. If you are pregnant or planning a pregnancy, ask your doctor about checking your haemoglobin.
Get medical help promptly if you notice:
- Chest pain, severe breathlessness or breathlessness at rest.
- Fainting or feeling as if you might pass out.
- Black, tarry stools or blood in your stool or vomit.
- Very heavy periods, such as soaking through a pad every hour or passing large clots.
- Symptoms of anaemia during pregnancy.
- Unexplained weight loss along with tiredness.
In an emergency, call 112 or go to the nearest hospital.
How nutrition and lifestyle may help
Food does not cure or treat Iron deficiency anaemia, but everyday habits can support your overall wellbeing alongside the care your doctor recommends.
Include iron-rich foods every day
Pulses, green leafy vegetables, millets such as bajra, and eggs, fish or meat if you eat them can contribute iron to your meals.
Pair plant iron with vitamin C
Adding lemon, amla, guava, oranges or tomato to meals may help your body absorb iron from plant foods.
Keep tea and coffee away from meals
Tea and coffee can reduce iron absorption. Try having them at least an hour before or after main meals.
Add seeds as easy boosters
Garden cress seeds (halim), sesame seeds and pumpkin seeds can be added to laddoos, raitas or salads.
Discuss supplements with your doctor
If you need iron tablets, your doctor will advise which one and for how long, and will recheck your blood.
Indian foods to include
- Rajma, chana and lobia
- Masoor and moong dal
- Palak, methi and bathua
- Bajra and ragi rotis
- Garden cress seeds (halim) and sesame seeds
- Eggs
- Fish, chicken or mutton for non-vegetarians
- Amla, guava and lemon for vitamin C
- Poha with peanuts and a squeeze of lemon
Key takeaways
- Tiredness, breathlessness and pale skin are the most common signs of iron deficiency anaemia.
- Heavy periods, pregnancy and low-iron diets are frequent causes in women.
- A blood test for haemoglobin and ferritin can confirm low iron.
- Pairing iron-rich Indian foods with vitamin C may help absorption.
- Take iron supplements only as advised by your doctor.
Iron deficiency anaemia: frequently asked questions
The first sign of low iron is usually tiredness or lack of energy that does not improve with rest. You may also get breathless more easily, look paler than usual or notice more hair fall. Because these signs are common and develop slowly, a blood test is the best way to know if low iron is the cause.
Yes, heavy periods are one of the most common causes of iron deficiency anaemia in women. Losing more blood each month can use up iron faster than your diet replaces it. If your periods are very heavy, last longer than a week or include large clots, see a doctor to check your iron and find the cause.
Yes, iron deficiency can contribute to hair shedding and thinning in women. Hair loss has many possible causes, including thyroid problems, hormonal changes and stress, so it is worth having a blood test rather than guessing. If low iron is found, correcting it under medical advice may help hair health over time.
Indian foods that contribute iron include rajma, chana, masoor dal, palak, methi, bajra, garden cress seeds and sesame seeds. Eggs, fish, chicken and mutton provide iron that the body absorbs more easily. Adding lemon, amla or guava to meals may help absorb iron from plant foods, while tea with meals can reduce it.
Recovery from iron deficiency anaemia usually takes weeks to a few months once the cause is treated. Many people start to feel more energetic within a few weeks of treatment, but rebuilding iron stores takes longer. Your doctor will usually repeat your blood test to check progress and decide how long treatment should continue.
No, it is best not to take iron tablets just because you feel tired. Tiredness has many causes, and taking iron you do not need can cause side effects and, rarely, harm. See a doctor for a blood test first. If you do have low iron, your doctor will advise the right supplement and duration.
