Anaemia iron deficiency living in pregnancy

Overview

Iron deficiency anaemia in pregnancy is a condition where your body does not have enough healthy red blood cells to carry oxygen to you and your baby. It happens when your iron levels are too low because your body needs more iron during pregnancy.

Yes, iron deficiency anaemia is one of the most common medical conditions during pregnancy, affecting around 1 in 5 pregnant women worldwide.

It primarily affects pregnant women, especially those in the second and third trimesters. Women with multiple pregnancies (twins, triplets), closely spaced pregnancies, or who had heavy periods before pregnancy are at higher risk.

Symptoms

Common symptoms

• Extreme tiredness and lack of energy
• Weakness and feeling faint
• Pale skin, lips, and nails
• Shortness of breath, even with mild activity
• Dizziness or lightheadedness
• Fast or irregular heartbeat (palpitations)
• Cold hands and feet
• Headaches

Causes

Main causes

• Your body needs more iron during pregnancy to make extra red blood cells for you and your baby. If your diet does not provide enough iron, levels can drop.
• Blood loss from delivery, heavy periods before pregnancy, or bleeding during pregnancy can reduce iron stores.
• Conditions like morning sickness or food aversions can make it hard to eat iron-rich foods.

Risk factors

• Having multiple babies (twins, triplets)
• Pregnancies that are close together (less than 18 months apart)
• Heavy menstrual periods before pregnancy
• A diet low in iron (for example, vegan or vegetarian without careful planning)
• Certain medical conditions like celiac disease or inflammatory bowel disease that affect nutrient absorption

When to see a doctor

See a doctor urgently if:

• If you have any of the emergency symptoms listed above
• If you feel you cannot cope with the tiredness or it is affecting your daily activities

Book a routine appointment if:

• If you notice persistent tiredness, pale skin, or shortness of breath during pregnancy
• At your regular antenatal appointments, your midwife or doctor will check your blood for anaemia

Diagnosis

Iron deficiency anaemia is diagnosed with a simple blood test. Your midwife or doctor will usually check your blood at your first antenatal appointment and again later in pregnancy.

Tests that may be done

• Full blood count (FBC) – measures the number and size of your red blood cells
• Ferritin level – shows how much iron your body has stored

What to expect at your appointment

The blood test is quick and involves a small needle prick in your arm. Results are usually available within a few days. If anaemia is found, your healthcare provider will discuss treatment options with you.

Treatment

Treatment for iron deficiency anaemia in pregnancy focuses on increasing your iron levels safely for you and your baby. This is usually done with iron supplements and changes to your diet.

Self-care at home

• Eat iron-rich foods such as lean red meat, poultry, fish, leafy green vegetables (like spinach), beans, lentils, and fortified cereals.
• Include vitamin C at meals to help your body absorb iron – for example, have a glass of orange juice, strawberries, or tomatoes with your iron-rich foods.
• Avoid drinking tea or coffee with meals, as they can reduce iron absorption. Wait at least an hour after eating.
• Get enough rest and listen to your body – do not push yourself to be active if you feel very tired.

Medical treatments

Your doctor or midwife may recommend oral iron supplements (tablets or liquid) that are taken daily. If your anaemia is severe or you cannot tolerate oral supplements, you may be offered intravenous (IV) iron given through a drip in a clinic or hospital. All treatment will be tailored to your needs and monitored regularly.

Living with this condition

Managing day-to-day with iron deficiency anaemia means pacing yourself. Plan rest breaks during the day, especially in the afternoon. Accept help from family and friends with household tasks. Keep a water bottle handy and eat small, frequent meals if you feel nauseous.

Lifestyle tips

• Prioritise sleep and rest – try to nap when your baby sleeps during the day.
• Do gentle activities like walking or stretching, but stop if you feel dizzy or short of breath.
• Keep your appointments with your midwife or doctor to check your progress.
• Talk to your partner or a trusted friend about how you are feeling – anaemia can affect your mood.

Diet and exercise

Eat a balanced diet with plenty of iron-rich foods and vitamin C. Aim for gentle exercise like short walks if you feel up to it – it can help improve your energy levels. Always check with your doctor before starting any new exercise during pregnancy.

Mental health and emotional wellbeing

Iron deficiency anaemia can make you feel tired, irritable, and low. It is common to feel overwhelmed. Remember that this is a physical condition that can affect your emotions too. If you feel anxious or depressed, speak to your midwife or doctor – they can offer support and, if needed, refer you to a mental health professional. If you have thoughts of harming yourself or your baby, call your local emergency number immediately.

Prevention

While not always preventable, you can lower your risk by eating an iron-rich diet before and during pregnancy. Many healthcare providers recommend a daily iron supplement during pregnancy as a preventive measure – follow the advice your doctor or midwife gives you.

Screening programmes

Routine blood tests in early pregnancy and again around 28 weeks can detect anaemia early, allowing prompt treatment. Screening is a standard part of antenatal care in many countries.

Complications

If left untreated

• Preterm birth (baby born too early)
• Low birth weight (baby smaller than expected)
• Baby may have lower iron stores at birth, which can affect their growth and development
• Increased risk of postpartum depression for the mother
• Greater fatigue and difficulty coping after birth

Long-term outlook

With proper treatment, iron deficiency anaemia during pregnancy has an excellent outlook. Most women feel better within a few weeks of starting treatment. Your baby will get the oxygen and nutrients they need, and you can have a healthy pregnancy and delivery. Follow your healthcare team's advice, and do not hesitate to ask for support if you are struggling.
