Overview
OB-GYN is a medical specialty that combines obstetrics and gynecology. Obstetrics involves care before, during, and after pregnancy, while gynecology focuses on the reproductive system, including the uterus, ovaries, cervix, vagina, and breasts. Many people see an OB-GYN for routine preventive care as well as for specific symptoms or life stages such as puberty, pregnancy, and menopause.
Key Symptoms
People may seek OB-GYN care for symptoms such as irregular periods, very heavy bleeding, bleeding between periods, pelvic pain, unusual vaginal discharge, pain during sex, or trouble becoming pregnant. OB-GYNs also evaluate symptoms related to pregnancy, including nausea, bleeding, reduced fetal movement, or concerns about labor. Breast symptoms such as a new lump or nipple discharge may also need prompt medical evaluation.
Who Is Affected
OB-GYN care is commonly used by people who have female reproductive organs, including adolescents, adults, pregnant people, and those going through menopause. Some people see an OB-GYN regularly for screening and preventive care, while others visit only when symptoms develop. Access needs can vary by age, medical history, sexual activity, pregnancy status, and personal or family health risks.
Prevention
Preventive OB-GYN care may include regular checkups, cervical cancer screening, vaccination such as HPV vaccination when appropriate, and discussions about sexual health and contraception. Preventing some complications also involves early prenatal care during pregnancy. Safer sex practices and timely treatment of infections can help reduce some reproductive health problems.
Diagnosis and Tests
An OB-GYN may diagnose health concerns using a medical history, physical exam, pelvic exam, pregnancy testing, blood or urine tests, and imaging such as ultrasound. Depending on the concern, testing may also include cervical screening, testing for sexually transmitted infections, or procedures to examine the uterus or cervix. The type of evaluation depends on the person's age, symptoms, and whether they are pregnant.
Treatment Categories
Treatment in OB-GYN depends on the condition and may include monitoring, counseling, non-surgical treatments, procedures, or surgery. Examples include care for pregnancy, support for contraception choices, evaluation of infertility, treatment of infections, and management of menstrual, pelvic floor, or menopause-related concerns. Some conditions need care from a wider team, such as midwives, primary care clinicians, fertility specialists, surgeons, or cancer specialists.
When to Seek Medical Care
Make a medical appointment for ongoing pelvic pain, missed periods when pregnancy is possible, unusual bleeding, bothersome menopause symptoms, signs of infection, new breast changes, or concerns about fertility. During pregnancy, seek medical advice promptly for bleeding, severe swelling, severe headache, fever, leaking fluid, or reduced fetal movement. It is also reasonable to schedule routine preventive visits even without symptoms.
When It May Be an Emergency
Emergency care may be needed for severe vaginal bleeding, fainting, severe pelvic or abdominal pain, symptoms of ectopic pregnancy, seizures during pregnancy, chest pain, trouble breathing, or heavy bleeding after childbirth. In pregnancy, urgent evaluation is also important for possible labor complications, severe headache with vision changes, or sudden swelling with other concerning symptoms. If someone feels very unwell or a symptom is rapidly worsening, seek urgent local medical help right away.
Questions to Ask a Healthcare Professional
You may want to ask what screenings or vaccines are appropriate for your age and health history, what symptoms need urgent attention, and what to expect from exams or tests. If you are pregnant, ask about prenatal visits, warning signs, birth planning, and postpartum care. If you have a gynecologic concern, ask about possible causes, treatment options, and whether follow-up or specialist referral is needed.
