Take on empty stomach with vitamin C; separate from antacids. * **IV iron**: Use for intolerance, non-response, late pregnancy needing rapid correction, malabsorption, or severe anaemia when oral not feasible. Iron sucrose (100–200 mg per dose) or FCM (single large dose 750–1000 mg). Monitor for reactions. * **Transfusion**: Individualise. Usually **Hb ≤7.0 g/dL** or symptomatic/hemodynamic compromise → transfuse. In obstetrics, clinical scenario dictates threshold. * **Follow-up**: Check Hb 2–4 weeks after therapy start and continue iron for 3 months after normalization. --- If you want, I can now: * Convert these into a **printable PDF** or a **spreadsheet** for easy use; * Expand any selected cases into **full exam-style long cases** (history prompts, viva questions, stepwise management) or **MCQs** derived from these cases; * Produce the **25 MCQs in stylish exam mode** (single HTML file with CSS/JS) instead — tell me which format you prefer next and I’ll produce it immediately. # Anaemia in pregnancy — complete, stylish clinical note > Compact, exam-friendly, evidence-backed reference you can paste into notes or teaching slides. Sources for the most important guideline facts are cited inline. --- ## 1) Definition (WHO) Anaemia = low haemoglobin (Hb) or red-cell mass causing reduced O₂-carrying capacity. **WHO threshold in pregnancy:** **Hb < 110 g/L (11.0 g/dL)** = anaemia; **severe** = **< 70 g/L (7.0 g/dL)**. ([World Health Organization][1]) --- ## 2) Pathophysiology (short) * Pregnancy → plasma volume ↑ ≈ 30–50% while red-cell mass ↑ less → physiologic haemodilution (lower Hb). * Pathologic anaemia results when iron supply (diet + stores) cannot meet increased maternal/fetal demands → reduced haemoglobin synthesis → microcytic hypochromic RBCs (longstanding). * Other mechanisms: haemoglobinopathy, folate/B12 deficiency, chronic inflammation (anemia of chronic disease, ACD), hemolysis, acute blood loss. --- ## 3) Iron requirements in pregnancy & prophylaxis (practical) * Pregnancy increases iron need substantially (for maternal RBC mass, placenta and fetus). Guidelines recommend **daily oral iron 30–60 mg elemental iron + 400 µg folic acid** for routine antenatal prophylaxis (start early, usually from 12 weeks or at first contact per local policy). For treatment, higher elemental doses are used (see below). ([World Health Organization][2]) --- ## 4) Public-health: Anemia Mukt Bharat & IFA logistics (India) * **Anemia Mukt Bharat (NHM)** emphasises six strategic actions including IFA supplementation, deworming, food fortification, testing & treatment, behaviour change and special management of severe cases. Weekly IFA formulations for adolescents/adults vary by group (e.g., 45–60 mg elemental iron + folic acid 400–500 µg for weekly program tablets); pregnant women receive daily IFA through ANC (tablet composition and supply per NHM/ANC). ([National Health Mission][3]) > Note about **“I-NIAP”**: I searched for a standard term “I-NIAP” and could not find an established definition. In obstetric literature you’ll see **AIP / NAIP** (Anemia In Pregnancy / Non-Anemic In Pregnancy) used in studies. If you meant a specific program/term, tell me and I’ll fetch it. ([sid.ir][4]) --- ## 5) Clinical history (what to ask) * Symptoms: fatigue, exertional dyspnoea, palpitations, syncope, orthopea, pica (pagophagia), restless legs, diminished exercise tolerance. * Obstetric: prior PPH, multiple pregnancies, short interpregnancy interval, hyperemesis, dietary restrictions, bleeding (menorrhagia pre-pregnancy), parasites, recent infections. * Drugs: antacids, calcium, tetracyclines (interfere with iron). * Family history: haemoglobinopathies (thalassaemia trait). --- ## 6) Physical examination (key findings) * Pallor (conjunctiva, palmar crease), tachycardia, glossitis, koilonychia (severe chronic), systolic flow murmur, signs of heart failure if severe. Look for hepatosplenomegaly (hemolysis/thalassaemia), lymphadenopathy (chronic disease). --- ## 7) Investigations — how to approach & interpretation **First-line tests** * CBC with RBC indices (Hb, Hct, MCV, MCH, MCHC), reticulocyte count, peripheral smear. * Ferritin (best single test for iron stores unless inflammation present), serum iron, TIBC/transferrin, transferrin saturation. ([MSD Manuals][5]) **Key numbers** * **MCV normal** ≈ 80–100 fL (microcytic <80 fL). (Use lab reference ranges.) ([MSD Manuals][5]) **Mentzer index** (practical discriminator) * **Mentzer = MCV (fL) / RBC count (10^6/µL)**. * **>13 → likely Iron Deficiency Anaemia (IDA)**. * **<13 → likely β-thalassaemia trait**. ([PMC][6]) **Peripheral smear** * IDA: microcytic hypochromic RBCs, anisopoikilocytosis, pencil cells. * ACD: often normocytic or mildly microcytic with low serum iron but low TIBC. Ferritin is normal or high in ACD (acute phase reactant). **Hb electrophoresis** * Indication: to detect β-thalassaemia trait or other hemoglobinopathies when indices suggest trait (normal/high RBC count, low MCV, Mentzer <13). Confirm with HbA₂ levels. ([PMC][7]) **Ferritin interpretation** * Low ferritin confirms iron deficiency; ferritin is raised in inflammation — interpret with CRP/ESR. WHO/technical guidance gives ferritin cutoffs and handling when inflammation present. ([World Health Organization][8]) --- ## 8) IDA vs Anaemia of Chronic Disease (ACD) — key contrasts * **IDA:** low ferritin, low serum iron, high TIBC (or normal), low transferrin saturation; microcytic hypochromic RBCs. * **ACD:** low serum iron, **low/normal TIBC**, normal/high ferritin, low transferrin saturation; usually occurs with infection/inflammation/chronic disease. Treatment targets underlying disease + careful iron management. ([World Health Organization][8]) --- ## 9) Differential diagnoses to consider * Iron deficiency, haemoglobinopathies (thalassaemia trait), folate/B12 deficiency, ACD, hemolytic anaemias, blood loss (antepartum/PPH), bone marrow disorders. --- ## 10) Complications & adverse effects of anaemia in pregnancy **Maternal effects** * Fatigue, reduced work capacity, increased risk of cardiac failure if severe, increased risk of peripartum transfusion and infection, poor wound healing, higher maternal mortality in severe anaemia. ([World Health Organization][9]) **Fetal/neonatal effects** * Preterm birth, low birth weight, intrauterine growth restriction, perinatal mortality, impaired neurodevelopment if severe/untreated. --- ## 11) Management — overview (prevention → treat → rescue) **Goals:** correct Hb, replete iron stores (ferritin), prevent recurrence, avoid transfusion when possible. ### A. Prevention (policy/antenatal) * Diet counselling (iron-rich foods + vitamin C to increase absorption; avoid tea/coffee with meals). * Routine **daily IFA prophylaxis: 30–60 mg elemental iron + 400 µg folic acid** (WHO). For national programs (India) follow Anemia Mukt Bharat / ANC protocols for supply and deworming. ([World Health Organization][2]) ### B. Oral iron — first-line for mild–moderate IDA and prophylaxis **Common salts & elemental iron content (practical)** * **Ferrous sulfate 325 mg** ≈ **65 mg elemental iron** (varies with hydrate). * **Ferrous fumarate 300 mg** ≈ **99–100 mg elemental iron**. * **Ferrous gluconate 300/325 mg** ≈ **35–39 mg elemental iron**. (Check product label.) ([NCBI][10]) **Indication (pregnancy):** treatment when IDA confirmed (mild–moderate), prophylaxis as above. **Dosing (typical)** * **Prophylaxis:** 30–60 mg elemental iron daily + 400 µg folic acid. ([World Health Organization][2]) * **Treatment (common practice):** many formularies use **60–120 mg elemental iron daily** (often given as 1 tab of ferrous sulfate 325 mg × 1–3 daily depending on severity) or **single daily higher elemental dose**; some guidelines/recent studies favour **lower daily doses (e.g., 60–80 mg elemental once daily)** or alternate-day dosing to improve tolerance and absorption — tailor to local guidance and tolerance. ([ScienceDirect][11]) **Mechanism of action:** provides elemental iron for haemoglobin synthesis; absorbed in duodenum via DMT1 after reduction to ferrous form. **Pharmacokinetics (summary):** oral iron variably absorbed (5–30% depending on iron status, enhancers/inhibitors). Food reduces absorption; vitamin C enhances. **Adverse effects (oral):** GI upset, nausea, abdominal pain, constipation or diarrhoea, black stools; adherence often limited by GI side effects. ([National Health Mission][12]) **Contraindications:** known hypersensitivity; caution with hemochromatosis. Check for haemoglobinopathy before prolonged high-dose therapy. **Key interactions:** antacids, calcium, tetracyclines, some antibiotics — separate dosing by 2–3 hours. Vitamin C coadministration improves absorption. **Monitoring:** Hb every 2–4 weeks until rise (aim Hb ↑ by ~1 g/dL in 2–4 weeks), ferritin at baseline and after repletion; monitor adherence and GI side effects. **Counselling points to patient:** take on empty stomach if tolerated (or with small vitamin-C-rich juice), avoid tea/coffee within 1–2 hours, black stools are common and harmless, constipation can be managed with stool softener/diet. Keep out of reach of children (ingestion is toxic). --- ### C. Parenteral (IV) iron — when to use **Indications in pregnancy** * Severe IDA not corrected by oral iron, intolerance or non-adherence to oral iron, late pregnancy where rapid correction needed, malabsorption, ongoing significant bleeding, or when quick Hb rise needed before delivery/cesarean. Avoid routine use in first trimester when possible. ([Wiley Online Library][13]) **Preparations & dosing (practical)** * **Iron sucrose (Venofer):** repeated doses (e.g., 100–200 mg per infusion; typical cumulative calculated by Ganzoni or dosing tables). Max ~200 mg per infusion commonly used; total depends on deficit. ([transfusionguidelines.org][14]) * **Ferric carboxymaltose (FCM; Injectafer/Ferinject):** allows **larger single doses (up to ~750–1000 mg per infusion, product-specific limits ~15–20 mg/kg, max 1000 mg single dose)** — useful to correct iron deficit quickly in 1–2 visits. ([injectaferhcp.com][15]) **Mechanism:** IV complexes deliver iron directly to reticuloendothelial system for incorporation into ferritin/haemoglobin. **Adverse effects (IV):** infusion reactions (including rare anaphylaxis with older dextran formulations), transient hypotension, nausea, arthralgia, local irritation; hypophosphatemia reported with some agents (e.g., FCM). Monitor for hypersensitivity during infusion. ([PMC][16]) **Monitoring:** vitals during infusion, monitor Hb/ferritin 2–4 weeks post infusion; check phosphate if using FCM and high cumulative dose. **Counselling:** explain need for IV access, possible transient side effects, and post-infusion monitoring. --- ### D. Blood transfusion — when & how (obstetric specifics) **Indications:** individualised — combine clinical state and Hb level. Many guidelines say transfusion is usual when **Hb < 60–70 g/L** or if symptomatic/hemodynamically unstable; rarely needed if Hb > 100 g/L. In obstetrics, clinical context (ongoing bleeding, cardiovascular compromise, labour) is decisive. Cross-match and plan ahead for high-risk women. Use single donor PRBCs, match Rh/K testing, and consider component therapy. ([RCOG][17]) **Risks:** transfusion reactions, alloimmunisation, infection risk (low with modern screening), transfusion-associated circulatory overload; plan restrictive transfusion strategy where safe. --- ## 12) Stepwise treatment algorithm (practical summary) 1. **Screen all pregnant women at booking** (Hb + RBC indices). If Hb <110 g/L → further tests (CBC, ferritin ± iron studies). ([World Health Organization][1]) 2. **If IDA confirmed (low ferritin):** start/optimise oral iron (elemental 60–120 mg/day, adjust to tolerance). Counsel. Monitor Hb rise at 2–4 weeks. If inadequate response or very late pregnancy / urgent correction required → **IV iron** (calculate total deficit; consider FCM or iron sucrose per availability). ([ScienceDirect][11]) 3. **If severe symptomatic anaemia (Hb <70 g/L) or haemodynamic instability:** consider blood transfusion (obstetric judgement). ([RCOG][17]) --- ## 13) Prevention of recurrence & antenatal program tips * Give full course until 3 months postpartum if previously anaemic, ensure deworming (in areas endemic for helminths) per national policy, ensure adequate dietary counselling, consider screening for haemoglobinopathies if family history or persistent microcytosis after iron repletion. Use Anemia Mukt Bharat operational modules to plan community IFA distribution and counselling. ([i4n.in][18]) --- ## 14) Quick bedside pocket facts (copy-paste) * **WHO anaemia in pregnancy:** Hb <11.0 g/dL. ([World Health Organization][1]) * **Routine prophylaxis:** **30–60 mg elemental iron + 400 µg folic acid daily.** ([World Health Organization][2]) * **Oral elemental iron examples:** ferrous sulfate 325 mg ≈ 65 mg Fe; ferrous fumarate 300 mg ≈ 99 mg Fe; ferrous gluconate 300 mg ≈ 35 mg Fe. ([NCBI][10]) * **Mentzer index:** MCV/RBC; **>13 → IDA**, **<13 → thalassaemia trait**. ([PMC][6]) --- ## 15) Practical templates (for your notes) **A. ANC counselling line:** “You have mild iron deficiency. I’m starting oral iron (example: ferrous sulfate 325 mg **once daily** = ~65 mg elemental iron) + folic acid — take on empty stomach or with orange juice, expect black stools; call if severe abdominal pain or fainting.” **B. IV iron note:** “Given poor response/intolerance to oral iron or late pregnancy, plan IV ferric carboxymaltose **(calculate total deficit; often one 1000 mg infusion)** — monitor vitals during infusion, check Hb & ferritin at 2–4 weeks.” --- ## 16) References / further reading (selected, guideline-level) * WHO Anaemia fact sheet & Hb thresholds.
