I now have enough information from the textbooks plus my medical knowledge to give you a very thorough, beginner-friendly guide. Let me write this up clearly.
How to Take History in the OB/GYN Ward - A Beginner's Guide for 3rd Year MBBS
Welcome to OB/GYN posting! Don't worry - history taking here follows the same general structure as any other ward, but with some special parts unique to this department. Here's everything broken down simply.
The Basic Structure (Same as Any Ward)
- Biodata
- Chief Complaint
- History of Present Illness
- Menstrual History ← OB/GYN special
- Obstetric History ← OB/GYN special
- Gynecological History ← OB/GYN special
- Past Medical/Surgical History
- Drug History
- Family History
- Personal/Social History
1. Biodata
Ask:
- Name, Age, Address
- Occupation (hers and husband's - important for stress, exposure, socioeconomic status)
- Religion (relevant for blood transfusion consent, contraception choices)
- Marital status and duration of marriage
2. Chief Complaint
Ask: "What problem has brought you to the hospital today?"
Common OB/GYN complaints you'll see:
- Pain in the abdomen / pelvis
- Vaginal bleeding (in pregnancy or outside pregnancy)
- Vaginal discharge
- Missed period / amenorrhea
- No pregnancy after trying (infertility)
- Swelling in abdomen
- Urinary problems (leaking urine, burning)
- Postmenopausal bleeding (very important - always take seriously)
- Labor pains
3. History of Present Illness (HPI)
Ask about the chief complaint in detail using the classic SOCRATES method:
- S - Site (where exactly?)
- O - Onset (when did it start? sudden or gradual?)
- C - Character (what type of pain? crampy, burning, dull?)
- R - Radiation (does it go anywhere else?)
- A - Associated symptoms (fever, nausea, vomiting, discharge?)
- T - Timing (constant or comes and goes? related to periods?)
- E - Exacerbating / Relieving factors
- S - Severity (scale of 1-10)
4. Menstrual History (MOST IMPORTANT in OB/GYN)
This is asked in EVERY single OB/GYN patient. Ask:
a) Age of Menarche - "At what age did your periods first start?" (Normal: 10-16 years)
b) Cycle - Use this format: Duration of flow / Length of cycle
- "How many days does bleeding last?" (Normal: 3-7 days)
- "How many days from the first day of one period to the first day of the next?" (Normal: 21-35 days)
- Write it as: 4-5 / 28-30 days (example)
c) Flow amount - "How many pads do you use per day?" (Normal: 3-5 pads/day)
- Heavy = soaking through pads within an hour = abnormal
- Ask about clots in the blood
d) Dysmenorrhea - "Do you have pain during your periods?" (Primary vs Secondary)
e) LMP (Last Menstrual Period) - "When was the first day of your LAST period?" - Write this date always
f) Regularity - Regular or irregular?
g) Intermenstrual bleeding - Any bleeding between periods?
h) Post-coital bleeding - Bleeding after sex? (Important - can suggest cervical pathology)
i) Menopause - If older patient: "Have your periods stopped? When?"
Remember: In a pregnant patient, LMP is used to calculate the Expected Date of Delivery (EDD) using Naegele's rule: Add 9 months + 7 days to LMP (or subtract 3 months and add 7 days).
5. Obstetric History (For Pregnant Patients or Those with Past Pregnancies)
Learn GPAL / GTPAL First!
| Letter | Meaning | Simple explanation |
|---|
| G | Gravida | Total number of pregnancies (including current one) |
| P | Para | Number of deliveries after 28 weeks (viable babies) |
| A | Abortion | Miscarriages or terminations before 28 weeks |
| L | Living | Number of children alive today |
Example: G3P2A1L2 = 3 pregnancies total, delivered 2 times, 1 miscarriage, 2 children alive
For EACH Previous Pregnancy, Ask:
- Year of delivery
- Duration of pregnancy (how many months/weeks at delivery?)
- Type of delivery - Normal vaginal / Cesarean section / Instrumental (forceps/vacuum)
- Where was delivery done? (hospital or home?)
- Baby's weight at birth (if known)
- Baby's sex and current health
- Any complications during that pregnancy? (blood pressure, diabetes, bleeding, fits/seizures)
- Postpartum complications? (excessive bleeding after delivery, infection, ICU admission)
- If miscarriage: how many weeks? Any D&C (cleaning procedure) done?
For the Current Pregnancy (Antenatal History):
- LMP and EDD - calculate gestational age
- Booking - Did she register for antenatal care? When? Where?
- ANC visits - How many check-ups so far?
- Fetal movements - "When did you first feel the baby move?" (Normal: 18-20 weeks in 1st pregnancy, 16-18 weeks in subsequent)
- Quickening - first feeling of fetal movement
- Immunizations - TT (Tetanus Toxoid) injections given?
- Investigations done - Blood group, hemoglobin, ultrasound scans
- Complications in this pregnancy - Bleeding, vomiting, swelling of feet, headache, blurred vision, reduced fetal movements, pain
- Medications - Iron, folic acid, calcium tablets?
6. Gynecological History
Ask about:
a) Contraception - "Are you using any family planning method?" (Pills, IUCD/copper T, injections, barrier methods, tubectomy)
b) Sexual history - Ask sensitively
- "Are you sexually active?"
- Any pain during intercourse (dyspareunia)?
- Any bleeding after sex (post-coital bleeding)?
c) Vaginal discharge - Color? Smell? Amount? Associated itching? Duration?
- White, curdy = Candida (fungal)
- Yellow/green, frothy = Trichomonas
- Grayish, fishy smell = Bacterial Vaginosis
d) Previous gynecological problems - Ovarian cysts, fibroids, pelvic inflammatory disease (PID)
e) Previous gynecological surgeries - Any operation on uterus, ovaries, tubes?
- D&C (dilation and curettage)
- Hysterectomy (removal of uterus)
- Myomectomy (removal of fibroids)
f) Cervical smear / Pap smear - Any screening done?
g) Infertility - Primary (never conceived) or Secondary (had a pregnancy before but unable now)? Duration? Any treatment?
7. Past Medical History
Ask about:
- Hypertension (very important - Pre-eclampsia risk)
- Diabetes (Gestational diabetes, macrosomia risk)
- Thyroid disease
- Tuberculosis (can cause infertility, Asherman's syndrome)
- Previous surgeries (especially abdominal/pelvic - adhesion risk)
- Blood transfusions (any reactions?)
- Epilepsy (drugs affect fetus)
- Anemia
8. Drug History
- Current medications (especially teratogenic drugs like thalidomide, valproate, ACE inhibitors - dangerous in pregnancy)
- Folic acid supplementation
- Iron tablets
- Any allergies to medicines?
9. Family History
- High blood pressure in family?
- Diabetes
- Twins (hereditary)
- Cancer (especially breast, ovarian, endometrial - important!)
- Congenital abnormalities / genetic disorders
10. Personal and Social History
- Diet - vegetarian/non-vegetarian, any nutritional deficiencies?
- Occupation - any heavy physical work, chemical exposure?
- Smoking - very important (preterm labor, placental abruption, IUGR risk)
- Alcohol - Fetal Alcohol Syndrome
- Socioeconomic status - affects nutrition, access to healthcare
- Stress levels
- Education - affects health literacy and compliance

Tips for Your First Day
- Always ask LMP - even before you ask anything else in OB/GYN. It orients everything.
- Be sensitive and non-judgmental - sexual history, infertility, and pregnancy losses are emotionally charged topics. Speak softly.
- Take history in the local language if English confuses the patient. Your seniors will respect this.
- Write G_P_A_L_ at the top of every OB/GYN case sheet clearly.
- Calculate gestational age from LMP on the spot - shows initiative.
- In a labor ward patient, focus on: current pregnancy details + previous deliveries + any complications.
- In a gynecology patient (non-pregnant), menstrual history and gynecological history are the main focus.

You are going to do great tomorrow! The staff and seniors know you're a 3rd year just starting - they don't expect you to know everything, just to ask the right questions politely and systematically. Good luck! 🩺
