Obstetrician-gynecologist: scope of work

An obstetrician-gynecologist is a physician responsible for the health of the female reproductive system at all stages: pregnancy planning, pregnancy management, childbirth, the postpartum period, and the treatment of gynecological diseases. This specialization combines the skills of obstetrics and gynecology: prevention, diagnosis, and treatment of reproductive diseases, as well as fertility preservation.

The specialist's key goal is to ensure the safety of the mother and fetus, promptly identify pathologies, minimize risks, and provide the patient with an informed choice of treatment. This requires the integration of clinical data, laboratory and instrumental studies, as well as multidisciplinary collaboration in complex cases. [1]

Obstetricians and gynecologists adhere to national and international guidelines for prenatal care, screening, and treatment of gynecological diseases. Modern practice includes the use of risk algorithms, early identification of complications, and personalized monitoring and therapy based on the patient's condition. [2]

Access to a competent obstetrician-gynecologist is especially important in the presence of risk factors, including age over 35 when planning a pregnancy, chronic illnesses, previous surgeries, hereditary pathologies, and reproductive problems. In such situations, monitoring should be more intensive and include additional examinations. [3]

Table 1. Key roles of the obstetrician-gynecologist

Role	What does it include?
Prenatal care	Confirmation of pregnancy, screening, monitoring of fetal development. [4]
Management of childbirth	Evaluation of indications, delivery, assistance in case of complications.
Treatment of gynecological diseases	Inflammation, fibroids, cysts, endometriosis, cervical dysplasia.
Reproductive medicine	Infertility diagnostics, planning, preparation for IVF according to indications. [5]

When to see an obstetrician-gynecologist: practical indications

You should seek medical attention if your period is more than three cycles late and you are not using contraception, if your periods are irregular or heavy, if you experience severe lower abdominal pain, any unusual vaginal discharge, spotting outside of your period, or pain during intercourse. Early screening reduces the risk of complications and preserves fertility during treatment.

An urgent consultation is indicated in acute conditions: significant blood loss, sudden and severe abdominal pain, signs of uterine flexion with intoxication, suspected ectopic pregnancy, high fever accompanied by lower abdominal pain. In such situations, rapid instrumental diagnostics and, possibly, urgent surgical intervention are necessary.

A routine consultation is required when planning a pregnancy or experiencing problems conceiving within 12 months of regular unprotected sexual activity for women under 35 years of age, and within 6 months for women 35 years of age and older. Prior to conception, a spouse examination, correction of chronic diseases, and adjustment of vaccinations as indicated are recommended. [6]

It's also worth consulting when planning contraception or choosing a method of hormone replacement therapy during menopause. Individual selection of the method reduces the risk of side effects and improves quality of life. [7]

Table 2. Simple triggers for seeking medical attention

Symptom	Action
Discharge with an unpleasant odor	Seek testing for infections.
Periods lasting more than 7 days or very heavy	Evaluation of the causes of bleeding and blood dilution.
Pain during intercourse	Assessment of genital and extragenital causes.
Delayed pregnancy	Confirmation and initiation of prenatal care. [8]

Diagnostics at the obstetrician-gynecologist: what is done and why

The initial consultation includes a thorough medical history, including menstrual function, sexual history, previous pregnancies, surgeries, chronic diseases, allergies, and medication use. This information guides the selection of laboratory and instrumental examinations.

Standard laboratory tests at the initial consultation and during preparation for pregnancy include a complete blood count, biochemistry, hormone levels as indicated, screening for sexually transmitted infections, and serological tests when planning a pregnancy. These tests help identify hidden risk factors.

Instrumental diagnostics include a speculum examination, cytology and microbiology smears, and ultrasound examination of the pelvic organs and mammary glands as indicated. If cervical pathology is suspected, a colposcopy and, if necessary, a biopsy are performed. Targeted ultrasound imaging is used at scheduled times to assess fetal development.

Current guidelines emphasize the need for an individualized approach to screening and imaging. Ultrasound before 24 weeks is important for accurate gestational age assessment and early detection of multiple or serious abnormalities. The examination plan is based on the patient's age and risk factors. [9]

Table 3. Frequent diagnostic tests and their purpose

Study	Target
Complete blood count and biochemistry	Assessment of general condition and identification of anemia and metabolic disorders.
Smear for cytology and PCR tests	Screening for dysplasia and sexually transmitted infections.
Ultrasound examination	Evaluation of the uterus, ovaries, good for confirming pregnancy. [10]
Colposcopy and biopsy	If cervical dysplasia or neoplasia is suspected.

Pregnancy management: monitoring structure and current recommendations

Prenatal care is aimed at optimizing maternal and fetal outcomes. World Health Organization recommendations call for at least eight contacts with the healthcare system to ensure a positive pregnancy experience and early detection of complications, with the model adjusted depending on the patient's risk. Local protocols may take into account resource availability and the epidemiological situation. [11]

During pregnancy, examinations to assess gestational age, screening tests for chromosomal abnormalities when indicated, hemoglobin levels, screening for gestational diabetes, testing for infections at risk, and scheduled ultrasound examinations at scheduled times are mandatory. All decisions should be transparent and discussed with the patient. [12]

Modern organizations recommend adapting the frequency of visits and the format of contacts according to indications: high-risk patients require more frequent monitoring and early consultation with specialists, while in the absence of risk factors, it is permissible to use a combined format of in-person and remote visits with careful monitoring. [13]

Early identification of threatened miscarriage, gestational hypertension, fetal growth retardation, and other complications allows for timely treatment or surgical intervention. Multidisciplinary collaboration with neonatologists, endocrinologists, and cardiologists improves outcomes in complex situations. [14]

Table 4. Standard elements of prenatal care

Stage	What do they do?
First trimester	Confirmation of the term, early screenings, basic tests. [15]
Second trimester	Targeted ultrasound, fetal anatomy screening. [16]
Third trimester	Fetal growth assessment, screening for preeclampsia if at risk. [17]
Postnatal period	Assessment of maternal recovery, recommendations for contraception and breastfeeding.

Treatment of gynecological diseases

Treatment for benign and inflammatory diseases ranges from conservative therapy to minimally invasive and radical surgeries, depending on the severity, the patient's age, and reproductive plans. For inflammation, targeted antibacterial regimens are used following microbiological testing.

For asymptomatic benign uterine and ovarian tumors, a dynamic observational approach is possible. In cases of severe symptoms, organ-preserving myomectomy, uterine artery embolization, or hysterectomy are considered if conservative treatment is ineffective. The choice depends on the tumor's size, location, and the desire to preserve fertility.

Oncologic diseases require standardized staging, multidisciplinary consultation, and a combination of surgery, radiation therapy, and systemic therapy when indicated. Decisions should be made taking into account gynecologic oncology guidelines and the capabilities of the center. [18]

In case of menstrual cycle disorders and hormonal imbalances, therapy includes correction of hormonal levels, treatment of concomitant metabolic disorders and, if necessary, the use of replacement therapy during menopause, taking into account contraindications.

Table 5. General decision-making framework in gynecology

Situation	First line	Next steps
Inflammation	Antibiotic therapy based on results	Monitoring and evaluation of complications.
Myoma has few symptoms	Observation	If symptoms occur, organ-preserving surgery is performed.
Suspected of malignancy	Biopsy and staging	Consultation, combination treatment. [19]

Prevention and preparation for pregnancy

Pregnancy preparation includes correcting chronic conditions, taking folic acid at least one month before conception and during the first 12 weeks of pregnancy, vaccinations as indicated, and quitting unhealthy habits. Assessing your reproductive profile and optimizing your health in a timely manner increases the likelihood of a favorable outcome. [20]

Preconception partner screening for reproductive problems, screening for sexually transmitted infections, and genetic counseling for a family history of hereditary diseases are recommended. The preconception care program is individualized. [21]

Early consultation is important when planning assisted reproductive technologies to assess indications, preserve fertility if necessary, and discuss potential risks and expectations. Reproductive medicine centers follow international guidelines for indications and safety. [22]

Prevention of complications in the postpartum period includes screening for postpartum depression, monitoring of blood loss, monitoring the blood coagulation system in case of risk, and recommendations on the timing and methods of contraception after childbirth.

Practical recommendations for the patient before the visit

Bring a list of current medications, allergies, previous prescriptions, and test results, including images and ultrasound reports, to your appointment. Honest and complete medical information speeds up diagnosis and reduces the likelihood of repeat testing.

Ask your doctor questions about your pregnancy plans, potential risks, and treatment options, taking into account your desire to preserve your reproductive function. Be sure to discuss possible side effects and recovery times for planned interventions. [23]

When planning a pregnancy, undergo recommended screenings and vaccinations before conception, manage chronic conditions if possible, and continue taking folic acid. If there are hereditary diseases in the family, consider genetic counseling. [24]

If symptoms are acute, don't wait – seek emergency care. For routine procedures, choose a clinic with access to the necessary diagnostic methods and multidisciplinary support, especially if there is a high risk of complications.
