Why OB/GYN History is Unique
Gynaecological and obstetric history is more nuanced than a general medical history because it involves intimate, often sensitive, and personal information about reproduction, sexuality, and bodily function. The key principles (from Berek & Novak's Gynecology, p. 39-55):
- Avoid being judgmental about sexual practices, gender identity, or orientation
- Establish trust and rapport first
- Allow the patient to speak freely before directing the interview
- Psychological, social, cultural, and family factors are all clinically relevant
- The assessment must address the "whole patient"
Structure of OB/GYN History
The history is divided into these sections:
1. Identifying Data
2. Chief Complaint (CC)
3. History of Present Illness (HPI)
4. Menstrual History
5. Obstetric History (GTPAL)
6. Sexual History
7. Contraceptive History
8. Gynaecological History (smears, STIs, procedures)
9. Past Medical and Surgical History
10. Drug History
11. Family History
12. Social History
13. Systems Review
1. Identifying Data
| Field | What to Ask |
|---|
| Name, age, date of birth | Basic identification |
| Marital/relationship status | Relevant to reproductive and social history |
| Occupation | Stress, toxin exposure |
| Ethnicity | Some conditions vary by race (e.g., fibroids more common in Black women) |
| Referred by | Who sent the patient and why |
2. Chief Complaint (CC)
Ask in the patient's own words: "What brings you in today?"
Common gynaecological chief complaints include:
| Complaint | Abbreviation/Term |
|---|
| Abnormal uterine bleeding | AUB |
| Pelvic pain | PP |
| Vaginal discharge | VD |
| Itching (vulval/vaginal) | Pruritus vulvae |
| Infertility | Primary (never conceived) or Secondary (previously conceived) |
| Urinary incontinence | UI |
| Postcoital bleeding | PCB |
| Postmenopausal bleeding | PMB |
| Lump or swelling in pelvis | - |
3. History of Present Illness (HPI)
Use the SOCRATES acronym to characterize the presenting complaint (especially pain or bleeding):
| Letter | Meaning | Example Question |
|---|
| S | Site | "Where exactly is the pain?" |
| O | Onset | "When did it start? Sudden or gradual?" |
| C | Character | "Is it crampy, stabbing, dull, burning?" |
| R | Radiation | "Does it spread anywhere - down the leg, to the back?" |
| A | Associations | "Any nausea, vomiting, fever, discharge with it?" |
| T | Time course | "Is it constant or does it come and go?" |
| E | Exacerbating/Relieving factors | "What makes it better or worse? Related to periods?" |
| S | Severity | "On a scale of 0-10, how bad is the pain?" |
4. Menstrual History
This is one of the most important parts of the gynaecological history. It tells you about the hormonal axis, uterine health, and ovarian function.
Key Questions and Terminology
| Term | Definition | What to Ask |
|---|
| Menarche | Age at first menstrual period | "How old were you when periods started?" |
| LMP | Last Menstrual Period - the first day of the last period | "What was the first day of your last period?" |
| Cycle length | Interval from Day 1 of one period to Day 1 of the next | "How many days between periods?" Normal = 21-35 days |
| Duration | How many days the period lasts | "How many days does bleeding last?" Normal = 3-7 days |
| Flow | Amount of bleeding | "How many pads/tampons per day? Do you pass clots?" |
| Dysmenorrhoea | Painful periods | "Do you have pain with your periods? Primary vs secondary?" |
| Menorrhagia | Heavy menstrual bleeding (>80 mL/cycle) | "Are your periods flooding or soaking through pads?" |
| Oligomenorrhoea | Infrequent periods (>35 days apart) | Cycles too far apart |
| Amenorrhoea | Absence of periods | Primary (never started) or Secondary (stopped >3 months) |
| Polymenorrhoea | Frequent periods (<21 days apart) | Cycles too close together |
| Menopause | Last menstrual period (confirmed after 12 months amenorrhoea) | "Have your periods stopped?" |
| IMB | Intermenstrual Bleeding - bleeding between periods | "Any bleeding between your periods?" |
| PCB | Postcoital Bleeding - bleeding after sex | "Do you bleed after intercourse?" |
| PMB | Postmenopausal Bleeding - any bleeding after menopause | Always investigate (rule out endometrial cancer) |
| Spotting | Very light, small amount of bleeding | Usually not enough to require a pad |
| Dyspareunia | Pain during intercourse | Superficial (at entry) or Deep (pelvic) |
Menstrual History Format
Document as: Cycle length / Duration, e.g.
- "28/5" = 28-day cycle, 5 days of bleeding (normal)
- "21/7" = 21-day cycle, 7 days bleeding
5. Obstetric History - GTPAL System
This is the standardized way to record a woman's full pregnancy history.
GTPAL Explained

| G | Gravida | Total number of pregnancies (including current), regardless of outcome |
| T | Term | Number of births at ≥37 weeks gestation |
| P | Preterm | Number of births between 20-36+6 weeks |
| A | Abortus | Number of losses before 20 weeks (spontaneous miscarriage + elective termination) |
| L | Living | Number of living children |
Key Obstetric Terms
| Term | Definition |
|---|
| Nulligravida | Never been pregnant |
| Primigravida | Currently pregnant for the first time |
| Multigravida | Has been pregnant more than once |
| Nullipara | Never delivered a viable baby |
| Primipara | Delivered one viable baby |
| Multipara | Delivered more than one viable baby |
| Grand multipara | Delivered 5 or more viable babies |
| Abortion | Pregnancy loss before 20 weeks (spontaneous or induced) |
| Miscarriage | Spontaneous pregnancy loss before 20 weeks |
| IUFD | Intrauterine Fetal Death (stillbirth - loss after 20 weeks) |
| Ectopic pregnancy | Pregnancy implanted outside the uterus (usually Fallopian tube) |
| EDD | Estimated Date of Delivery (= LMP + 280 days / Naegele's Rule) |
| EGA / GA | Estimated gestational age |
GTPAL Example
"A 32-year-old woman who had twins at 36 weeks, then a term baby at 39 weeks, one miscarriage at 10 weeks, and all 3 children are living. Now pregnant again."
- G = 4 (4 pregnancies including current)
- T = 1 (the 39-week delivery)
- P = 1 (twins at 36 weeks = preterm)
- A = 1 (miscarriage)
- L = 3 (three living children)
Documented as: G4 T1 P1 A1 L3
For Each Previous Pregnancy, Also Ask:
- Year of birth

Technique of Taking the History (Berek & Novak's Method)
From Table 1-5, Berek & Novak's Gynecology, p. 54-55:
- Allow the patient to express the chief symptom in her own words - do not interrupt
- Establish the temporal relationship - when did this start? What were you doing?
- Use open-ended questions first ("Tell me about the bleeding"), then narrow with closed questions
- Avoid leading questions that suggest the answer
- Explore the symptom thoroughly before moving to the next
- Take note of what the patient is not saying - sometimes silence or hesitation signals important issues
- At the end, summarize back to the patient and ask: "Is there anything else you feel I should know?"
