How to Prepare Obstetrics and Gynaecology for NEET PG: Strategy and High-Yield Topics
OBG carries 15-20 questions in NEET PG. High-risk pregnancy, labour management, and gynaecological malignancies are the three pillars -- clinical reasoning matters more than textbook definitions.
Why Obstetrics and Gynaecology matters for NEET PG
Obstetrics and Gynaecology (OBG) is one of the heavyweight clinical subjects in NEET PG, contributing approximately 15 to 20 questions out of 200. It combines two distinct but related specialties: obstetrics (pregnancy, labour, and puerperium) and gynaecology (non-pregnant female reproductive pathology). The questions are overwhelmingly clinical -- a pregnant woman presents at 34 weeks with severe headache and blood pressure of 160/110, and you need to manage her.
Obstetrics dominates the question distribution at roughly 60% of OBG questions, with high-risk pregnancy, labour management, and antepartum haemorrhage being the three most tested areas. Gynaecology contributes the remaining 40%, with gynaecological malignancies, menstrual disorders, and contraception leading the question count.
OBG has strong overlap with anatomy (pelvic anatomy, embryology), pharmacology (drugs in pregnancy -- teratogenicity, tocolytics, oxytocics), and paediatrics (neonatal resuscitation, birth injuries). A solid foundation in these subjects makes OBG significantly more manageable. The subject also requires knowledge of specific Indian guidelines -- FOGSI protocols, MTP Act provisions, and PCPNDT Act -- which are directly tested.
Subject weight and question distribution
Expect 15 to 20 questions per paper, constituting 7.5-10% of the total. Obstetrics accounts for roughly 55-65% of OBG questions, led by high-risk pregnancy (pre-eclampsia, gestational diabetes, Rh isoimmunisation) at about 25-30% of the total. Labour and delivery management contribute another 15-20%. Gynaecology contributes 35-45%, with malignancies (cervical, ovarian, endometrial) at about 15-20% and menstrual disorders and contraception at about 10-15% each.
The trend since 2022 is toward more scenario-based questions requiring management decisions rather than classification recall. Questions increasingly present complications during labour and ask for the next step in management.
High-yield topics
- **Pre-eclampsia and Eclampsia:** 3-4 questions per paper across obstetrics. Diagnostic criteria (BP >140/90 + proteinuria after 20 weeks), severe pre-eclampsia features (BP >160/110, HELLP syndrome, visual disturbances), magnesium sulphate regimen (Pritchard or Zuspan), and the definitive treatment (delivery). Know the magnesium toxicity signs (loss of patellar reflex, respiratory depression) and antidote (calcium gluconate).
- **Antepartum Haemorrhage:** 2-3 questions per paper. Placenta praevia (painless bright red bleeding, confirmed by USG -- NEVER perform vaginal exam until USG rules out praevia), abruptio placentae (painful dark bleeding, woody hard uterus, DIC risk, concealed haemorrhage can occur without visible bleeding). Management depends on gestational age, severity, and fetal condition.
- **Labour Management:** 2-3 questions per paper. Partograph interpretation (cervicograph crossing the action line = indication for intervention), stages of labour definitions and durations, indications for caesarean section (absolute: CPD, major placenta praevia, transverse lie; relative: failed induction, fetal distress), and active management of third stage (controlled cord traction + uterotonic).
- **Gynaecological Malignancies:** 2-3 questions per paper. Cervical carcinoma (HPV 16/18, screening with Pap smear/VIA, FIGO staging -- note: cervical cancer is CLINICALLY staged), ovarian tumours (surface epithelial most common, CA-125 for serous, AFP for yolk sac, beta-hCG for choriocarcinoma), and endometrial carcinoma (unopposed oestrogen, most common gynaecological malignancy in developed countries, SURGICALLY staged).
- **Contraception:** 1-2 questions per paper. Combined OCP mechanism and contraindications (>35 years + smoking, history of DVT, migraine with aura), IUDs (Cu-T: mechanism, timing of insertion, complications), emergency contraception (levonorgestrel within 72 hours, ulipristal within 120 hours), and sterilisation (tubectomy methods, failure rates).
- **Ectopic Pregnancy:** 1-2 questions per paper. Risk factors (PID, previous ectopic, IVF, IUCD), presentation (amenorrhoea + abdominal pain + vaginal bleeding + positive beta-hCG with no intrauterine gestational sac on USG), management (methotrexate for unruptured with beta-hCG <5000, surgical for ruptured). Ampulla is the most common site.
- **Gestational Diabetes and Medical Disorders in Pregnancy:** 1-2 questions per paper. GDM screening (DIPSI in India: 75g glucose at any time, plasma glucose >140 = GDM), insulin management (metformin is acceptable but insulin remains standard for inadequate control), and thyroid disorders in pregnancy (PTU in first trimester, methimazole in second and third trimesters). Drug safety in pregnancy is heavily tested.
- **Abnormal Uterine Bleeding:** 1-2 questions per paper. PALM-COEIN classification (FIGO), DUB management ladder (medical: tranexamic acid + NSAIDs for acute, hormonal for chronic; surgical: hysteroscopy, endometrial ablation, hysterectomy), and fibroid-related AUB (submucosal fibroids cause menorrhagia, management depends on size and fertility desire).
- **Rh Isoimmunisation:** 1 question per paper on average. Indirect Coombs test for maternal sensitisation, middle cerebral artery Doppler peak systolic velocity for non-invasive fetal anaemia assessment (replaced amniocentesis), anti-D immunoglobulin administration (28 weeks antenatally and within 72 hours of delivery/abortion). Kleihauer-Betke test for fetomaternal haemorrhage quantification.
Recommended study approach
DC Dutta's Textbook of Obstetrics and Textbook of Gynaecology are the standard references for Indian PG exams. For a more concise alternative, Sheila Balakrishnan's textbook is popular. Study obstetrics first (it carries more weight), then gynaecology. Within obstetrics, start with high-risk pregnancy (2 weeks), then normal and abnormal labour (1.5 weeks), then antepartum care and complications (1 week). Within gynaecology, start with malignancies (1 week), then menstrual disorders (1 week), then contraception and miscellaneous (1 week).
For each obstetric condition, master the management algorithm based on gestational age and severity. The exam frequently tests whether the answer is 'deliver immediately,' 'expectant management with monitoring,' or 'specific medical intervention.' These decisions are gestational-age-dependent, and blanket answers without gestational context score zero.
Integrate OBG pharmacology as you study each topic. Drugs in pregnancy (teratogenicity categories, safe antibiotics, antihypertensives in pregnancy -- labetalol/nifedipine, NOT ACEi/ARBs) are tested both in OBG and pharmacology sections.
Time allocation
OBG requires 6-7 hours per week, totalling roughly 150-180 hours across your preparation. Split 45-55 between reading and MCQ practice. Obstetrics should receive roughly 60% of your OBG time, reflecting its higher question contribution.
If short on time, focus on pre-eclampsia/eclampsia (covers 3-4 questions), antepartum haemorrhage (covers 2-3 questions), and gynaecological malignancies (covers 2-3 questions). These three areas together account for 40-50% of OBG questions. Labour management is also high-yield but can be partially covered through clinical posting experience.
Common mistakes to avoid
- Not knowing gestational-age-specific management -- the management of pre-eclampsia at 28 weeks vs 37 weeks is fundamentally different, and the exam tests this distinction
- Confusing clinical vs surgical staging in gynaecological malignancies -- cervical cancer is clinically staged (even after surgery), while endometrial and ovarian cancers are surgically staged
- Ignoring Indian-specific guidelines -- MTP Act (up to 24 weeks with specific conditions after 2021 amendment), PCPNDT Act, and FOGSI protocols are directly tested
- Studying obstetrics and gynaecology as the same subject -- they require different study approaches: obstetrics is algorithm-driven, gynaecology is classification-driven
- Skipping drugs in pregnancy because it is 'pharmacology' -- drug safety in pregnancy is tested in OBG, pharmacology, and paediatrics, and accounts for 3-4 questions across the paper
Recommended resources
DC Dutta's Textbook of Obstetrics and Textbook of Gynaecology are the primary texts. Dutta is comprehensive, exam-aligned, and the standard recommendation. For gynaecological oncology specifically, Jeffcoate's Principles of Gynaecology provides additional depth. Shaw's Textbook of Gynaecology is an alternative.
For revision, Sakshi Arora's review book covers OBG concisely. Supplement with FOGSI clinical practice guidelines for management algorithms, and ACOG/NICE guidelines for evidence-based management where Indian guidelines are silent.
Last-month revision strategy
In the final month, OBG should receive 1.5-2 hours daily. Focus on: (1) pre-eclampsia and eclampsia management algorithm including magnesium sulphate regimen; (2) APH management (placenta praevia vs abruption decision tree); (3) gynaecological malignancy staging and management; (4) drugs in pregnancy safety.
Solve 3-4 PYQ sets for OBG. The clinical scenarios are consistent -- the same high-risk pregnancy presentations, the same labour complications, the same gynaecological malignancy stagings. Pattern recognition built through PYQ practice is the single most effective last-month strategy for OBG.
Frequently Asked Questions
How many OBG questions come in NEET PG?
Typically 15 to 20 out of 200. Obstetrics contributes roughly 60% and gynaecology 40%. Pre-eclampsia and gynaecological malignancies are the two single highest-yield topics.
Should I study obstetrics and gynaecology together?
Study them sequentially, not simultaneously. They are distinct specialties with different question patterns. Complete obstetrics first (higher yield), then move to gynaecology.
How important are Indian-specific guidelines?
Very important. MTP Act provisions, PCPNDT Act, FOGSI protocols, and the DIPSI method for GDM screening are directly tested. These are not covered in international textbooks.
Is Dutta sufficient for NEET PG OBG?
Yes. Dutta covers both obstetrics and gynaecology comprehensively for exam purposes. Supplement with a review book for revision and FOGSI guidelines for management algorithms.
