Iron deficiency anaemia

Iron deficiency anaemia

Iron deficiency anaemia happens when the body does not have enough iron to make healthy haemoglobin, the part of red blood cells that carries oxygen. Common causes include heavy periods, pregnancy, blood loss from the stomach or bowel, low iron intake, or problems absorbing iron. Anaemia can also have causes other than low iron, so blood tests and assessment of the cause are important.

Symptoms

Symptoms may develop gradually and can include:

Tiredness, low energy, or reduced exercise tolerance

Shortness of breath, especially on exertion

Feeling dizzy, light-headed, or having headaches

Noticeable or fast heartbeats

Pale skin, lips, or inside the eyelids

Cold hands and feet

Difficulty concentrating or feeling unusually irritable

Sore tongue, cracks at the corners of the mouth, hair loss, or brittle nails

Craving non-food items such as ice, soil, or paper

Restless legs, especially at night

Some people have only mild symptoms, even when their iron stores are low.

Red flags

Iron deficiency anaemia - Red flags

Go to the nearest hospital urgently, or call Ambulance Nepal on 102 where available, if you have:

Chest pain, severe breathlessness, or breathlessness at rest

Fainting, collapse, new confusion, or extreme weakness

A very fast or irregular heartbeat with dizziness or feeling unwell

Vomiting blood, black sticky stools, blood in stool, or heavy ongoing bleeding

Very heavy vaginal bleeding, such as rapidly soaking pads or passing large clots

Severe symptoms during pregnancy, after childbirth, or following major blood loss

A child who is very sleepy, breathing quickly, feeding poorly, or looks very pale and unwell

These symptoms may suggest severe anaemia, significant bleeding, or another serious illness that needs urgent assessment. Ambulance Nepal lists 102 as its emergency number.

Self-care

Self-care

Eat a varied diet with iron-rich foods, such as meat, fish, eggs, lentils, beans, chickpeas, dark green leafy vegetables, and iron-fortified foods.

Include vitamin C-rich foods, such as citrus fruit, guava, tomatoes, peppers, or other fruit and vegetables, as these can help iron absorption.

Avoid tea, coffee, cocoa, and large amounts of dairy at the same time as iron-rich meals or prescribed iron treatment, as they can reduce iron absorption.

If heavy periods, poor diet, pregnancy, stomach symptoms, or bowel changes may be contributing, discuss this with a health professional.

Do not diagnose iron deficiency from symptoms alone or start long-term iron tablets without advice. Too much iron can be harmful, especially for children. Keep iron medicines out of children's reach.

Treatment

Treatment should address both the low iron and the reason it developed.

A doctor will usually arrange blood tests, including a full blood count and iron studies. Oral iron tablets or liquid are commonly used when iron deficiency is confirmed. Treatment often continues for several months, with repeat blood tests to check response and rebuild iron stores.

Iron treatment can cause constipation, diarrhoea, nausea, stomach discomfort, heartburn, or darker stools. Tell a clinician if side effects are troublesome rather than stopping treatment without advice.

Some people may need intravenous iron, especially if tablets are not tolerated, do not work, cannot be absorbed properly, or the anaemia needs more rapid correction. Heavy periods, pregnancy-related needs, stomach or bowel bleeding, dietary problems, and absorption disorders may also need separate treatment.

Questions to ask your doctor

Iron deficiency anaemia - Questions to ask doctor

Is this definitely iron deficiency anaemia, or could there be another cause?

What may be causing my iron deficiency?

Do I need tests for heavy bleeding, stomach or bowel blood loss, coeliac disease, infection, or another condition?

Which iron treatment is suitable for me, and how long should I take it?

When should my blood test be repeated?

What side effects should I expect, and what should I do if they occur?

Could any of my regular medicines be contributing to blood loss or poor iron absorption?

Do I need specialist referral or intravenous iron?

Which symptoms mean I should seek urgent medical help?
