Antenatal Care Guide (Nigeria)

Complete guide to pregnancy check-ups โ€” what happens at each visit and why it matters

Nigeria has one of the highest maternal mortality rates in the world โ€” approximately 512 per 100,000 live births. Most of these deaths are preventable with adequate antenatal care (ANC). This guide explains what antenatal visits are, what happens at each one, and why attending all recommended visits is critical for both mother and baby. The standard is at least 8 antenatal visits, as recommended by WHO and the Nigerian government.

Signs and Symptoms

โœ“ Normal pregnancy symptoms: missed period, nausea, breast tenderness, fatigue, urinary frequency
โœ“ WARNING โ€” vaginal bleeding at any stage of pregnancy needs same-day assessment
โœ“ WARNING โ€” severe headache, visual disturbance, or facial swelling after 20 weeks โ€” pre-eclampsia signs
โœ“ WARNING โ€” reduced fetal movements after 28 weeks โ€” report same day
โœ“ WARNING โ€” severe abdominal pain โ€” placental abruption or appendicitis
โœ“ WARNING โ€” fever with chills โ€” malaria in pregnancy is dangerous
โœ“ WARNING โ€” leakage of fluid from the vagina before 37 weeks โ€” premature rupture of membranes

Risk Factors

When to Seek Help

Emergency โ€” go immediatelyHeavy vaginal bleeding, severe abdominal pain, fits or convulsions, loss of consciousness, severe headache with visual changes โ€” obstetric emergency
Same dayAny vaginal bleeding, reduced fetal movements, leakage of fluid before 37 weeks, fever with rigors
As soon as pregnancy confirmedRegister for antenatal care โ€” ideally before 10 weeks (first trimester booking)
Routine ANC scheduleFirst visit <12 weeks, then at 16, 20, 24, 28, 32, 36, 38, and 40 weeks โ€” minimum 8 contacts per WHO guidance
Any concernsNever wait for your next appointment if something feels wrong โ€” attend the nearest health facility

Tests & Diagnosis

๐Ÿงช Blood group and Rhesus factor
Rh-negative mothers need anti-D immunoglobulin at 28 weeks and after delivery to prevent haemolytic disease in future pregnancies
๐Ÿงช Full blood count (FBC)
Anaemia is very common in Nigerian pregnant women โ€” treat iron deficiency with oral iron supplementation
๐Ÿงช HIV test
Offered to all pregnant women โ€” PMTCT (prevention of mother-to-child transmission) with ARVs is highly effective. Confidential
๐Ÿงช VDRL/RPR (syphilis screening)
Untreated syphilis causes stillbirth, neonatal death, and congenital syphilis. Treat with benzathine penicillin
๐Ÿงช Malaria blood film or RDT
Malaria is a leading cause of maternal anaemia and low birth weight. Intermittent preventive treatment with sulfadoxine-pyrimethamine (SP/Fansidar) given at each ANC visit after 16 weeks regardless of symptoms
๐Ÿงช Urine dipstick (protein and glucose)
Proteinuria โ€” screen for pre-eclampsia. Glucosuria โ€” screen for gestational diabetes
๐Ÿงช Ultrasound scan
Dating scan at 8โ€“12 weeks (confirms gestation). Anomaly scan at 18โ€“20 weeks (detects structural abnormalities). Growth scans at 28โ€“32 weeks if needed
๐Ÿงช Blood pressure measurement
At every visit โ€” rising BP is the key sign of pre-eclampsia

Treatment Options

1
Folic acid โ€” start before or as soon as pregnancy confirmed
400 mcg daily in the first 12 weeks to prevent neural tube defects (spina bifida). Women with epilepsy on valproate or carbamazepine need 5 mg daily
2
Iron and folate supplements
Ferrous sulphate 200 mg (65 mg elemental iron) twice daily throughout pregnancy โ€” the most common deficiency in Nigerian pregnancy. Take with vitamin C (orange juice) to enhance absorption. Do not take with tea or calcium
3
Malaria prevention โ€” IPTp
Sulfadoxine-pyrimethamine (SP/Fansidar) at each ANC visit from 16 weeks onwards โ€” at least 3 doses. Safe and reduces low birth weight. Plus insecticide-treated bed net (ITN) โ€” provided free in many Nigerian states
4
Tetanus toxoid vaccination
At least 2 doses โ€” protects against neonatal tetanus (a major cause of neonatal death in Nigeria). Ideally 5 lifetime doses for complete protection
5
Hypertension in pregnancy
Labetalol or methyldopa (safe in pregnancy). Avoid ACE inhibitors, ARBs, and NSAIDs โ€” dangerous to fetus. Aspirin 75 mg daily from 12 weeks for high-risk women (previous pre-eclampsia, diabetes, kidney disease)
6
Diabetes management in pregnancy
Dietary modification first-line. If blood glucose poorly controlled โ€” insulin (not metformin or sulphonylureas as first choice). Monitor HbA1c and fetal growth closely
7
HIV in pregnancy (PMTCT)
All HIV-positive pregnant women start lifelong antiretroviral therapy regardless of CD4 count. Preferred regimen: TDF + 3TC + EFV. Reduces transmission from 25โ€“45% to <1% with optimal adherence
8
Sickle cell disease in pregnancy
High-risk pregnancy โ€” manage jointly with haematologist. Regular FBC, prophylactic folic acid 5 mg daily, avoid dehydration, malaria prevention, crisis management
9
Birth planning
Identify nearest facility with emergency obstetric care (EmOC). Identify a birth companion and transport. Prepare blood donors. Know the warning signs requiring emergency response

Frequently Asked Questions

How many antenatal visits should I attend?
WHO recommends at least 8 antenatal contacts. Nigeria's government policy supports this. Key visits: booking (<12 weeks), 16 weeks, 20-week scan, 24 weeks, 28 weeks (anti-D if Rh negative, IPTp dose), 32 weeks, 36 weeks (delivery planning), and 38โ€“40 weeks. Every visit matters.
Is it safe to take malaria treatment during pregnancy?
Artemisinin combination therapies (ACTs) โ€” e.g., artemether-lumefantrine โ€” are safe for malaria treatment in the second and third trimesters. In the first trimester, quinine or artemisinin (with caution) is used. Untreated malaria in pregnancy is far more dangerous than treatment. Preventive SP (Fansidar) is given routinely.
Can I travel during pregnancy?
Domestic travel is generally safe in the second trimester. Long-distance travel is best avoided after 36 weeks. Air travel is safe until 36 weeks for uncomplicated pregnancies (most airlines restrict after 36 weeks). Avoid areas with high malaria risk without adequate prophylaxis. Ensure a healthcare facility is accessible at your destination.
What are the danger signs I should never ignore?
Heavy vaginal bleeding, severe headache, visual blurring or seeing spots, severe facial or hand swelling, fits or seizures, reduced fetal movements, high fever, or leaking amniotic fluid before 37 weeks. Any of these requires emergency assessment immediately โ€” do not wait.
