What Does an OBGYN Do? From Routine Care to Surgery

An Obstetrician-Gynecologist (OBGYN) is a physician specializing in the medical and surgical care of the female reproductive system. This professional provides comprehensive health services across a woman’s lifespan, from adolescence through the post-menopausal years. Their practice involves managing reproductive health, providing preventative care, and offering medical care during and after pregnancy. An OBGYN diagnoses and treats a wide range of specific conditions affecting the female body.

Preventative and Routine Gynecological Care

The OBGYN provides routine, preventative care aimed at maintaining long-term reproductive health and detecting potential issues early. This begins with the annual wellness exam, which includes a comprehensive review of the patient’s medical history, menstrual cycle patterns, and reproductive intentions. The physical exam often includes a clinical breast check and a pelvic exam to assess the health of the reproductive organs.

Cervical cancer screening is a cornerstone of preventative work, performed using a Papanicolaou test (Pap smear) to collect cells from the cervix and check for abnormalities. For women between the ages of 21 and 65, this screening is performed every three to five years, sometimes combined with human papillomavirus (HPV) testing. Routine care also involves counseling and screening for sexually transmitted infections (STIs), such as chlamydia and gonorrhea, particularly in sexually active individuals.

Contraceptive management is a primary service, encompassing detailed discussions about various family planning methods, their effectiveness, risks, and benefits. OBGYNs prescribe hormonal options like birth control pills, patches, and vaginal rings. They also administer long-acting reversible contraceptives (LARCs) such as subdermal implants or intrauterine devices (IUDs).

Management of Reproductive Health Conditions

When disorders arise, the OBGYN transitions to the medical diagnosis and non-surgical management of specific reproductive health conditions. They manage hormonal disorders like Polycystic Ovary Syndrome (PCOS), often treated with lifestyle modifications and medications such as Metformin to improve insulin resistance. Hormonal contraceptives are commonly prescribed to regulate irregular menstrual cycles and manage symptoms resulting from elevated androgen levels, including acne and excess hair growth.

The treatment of endometriosis, a disorder where tissue similar to the uterine lining grows outside the uterus, focuses on managing pain and reducing tissue growth. This involves hormonal therapy, such as continuous oral contraceptives or progestin therapy, which suppresses the menstrual cycle and minimizes hormonal stimulation of the lesions. Uterine fibroids, which are non-cancerous growths, can also be managed medically using hormonal agents to control heavy menstrual bleeding and pelvic pressure before considering surgery.

OBGYNs provide specialized care for women transitioning through menopause and perimenopause, managing symptoms such as hot flashes and mood changes. They discuss options like hormone replacement therapy (HRT) to alleviate discomfort and support bone health. For patients struggling to conceive, the OBGYN initiates the infertility workup, performing initial diagnostic testing and prescribing ovulation-inducing medications like clomiphene or letrozole before referral to a reproductive endocrinologist.

Obstetric Care and Pregnancy Management

The “Obstetrics” portion of the specialty focuses on the continuum of care surrounding pregnancy, beginning before conception. Pre-conception counseling helps patients optimize their health, review medications, and discuss nutrition, including folic acid supplementation. Once pregnancy is established, the OBGYN provides routine prenatal care, involving scheduled visits to monitor the health of both the mother and the developing fetus across all three trimesters.

Prenatal visits include physical assessments, blood pressure monitoring, and laboratory testing to screen for conditions like gestational diabetes and preeclampsia. Regular ultrasound examinations track fetal growth, development, and positioning, identifying potential complications early. The expertise of an OBGYN extends to managing high-risk pregnancies, such as maternal hypertension, multiple gestations, or previous preterm births, often requiring more frequent monitoring and specialized interventions.

During labor and delivery, the OBGYN is responsible for all aspects of the birthing process, including spontaneous vaginal delivery or planned or emergent Cesarean section. They handle delivery complications and neonatal resuscitation, ensuring the safest possible outcome for both mother and child. Postpartum care focuses on the mother’s physical recovery, mental health screening for conditions like postpartum depression, and counseling on breastfeeding and future contraceptive options.

Surgical Procedures Performed

OBGYNs are surgeons who perform a broad scope of procedures, ranging from minor outpatient interventions to complex major abdominal operations. Many treatments utilize minimally invasive techniques, such as laparoscopy and hysteroscopy, which use small incisions or natural openings to reduce recovery time and scarring.

Minimally Invasive Procedures

Laparoscopy is often used to diagnose and treat endometriosis, remove ovarian cysts, or perform tubal sterilization (ligation). Hysteroscopy involves inserting a thin, lighted telescope through the cervix into the uterus, allowing the OBGYN to visualize the uterine cavity and perform procedures like endometrial ablation or the removal of polyps and small fibroids.

Major Procedures

When extensive intervention is required, such as for large fibroids or certain cancers, major surgery may be necessary. The most common major gynecological surgery is a hysterectomy, which involves the removal of the uterus, often performed to treat severe, uncontrolled bleeding, large fibroids, or pelvic organ prolapse. A myomectomy is a procedure designed to remove fibroids while preserving the uterus for future fertility.

Minor Procedures

Minor procedures performed in the office or operating room include the Loop Electrosurgical Excision Procedure (LEEP) to remove abnormal cells from the cervix after an irregular Pap smear and dilation and curettage (D&C) to remove tissue from the uterus for diagnostic purposes or after a miscarriage.
