Dr. Xydas earned his medical degree from the University of Texas Southwestern Medical School. He then completed residency training in obstetrics and gynecology at Tulane University.

OB-GYN residency prepares physicians to provide prenatal care, manage childbirth, evaluate reproductive health symptoms, perform gynecological procedures, respond to pregnancy emergencies, and provide preventive care throughout adulthood.

Board Certification and Professional Credentials

Dr. Xydas is board-certified in obstetrics and gynecology.

His professional credentials include:

• MD, meaning Doctor of Medicine
• Residency training in obstetrics and gynecology
• Board certification through the American Board of Obstetrics and Gynecology
• FACOG, meaning Fellow of the American College of Obstetricians and Gynecologists
• Experience in general gynecology and pregnancy care

Board certification is different from medical licensing. A medical licence allows a doctor to practise medicine within a jurisdiction, while board certification reflects specialist training and professional assessment.

Preventive Gynecological Care

Preventive gynecology helps identify reproductive and general health concerns before they become more difficult to manage.

A routine visit may include:

• Menstrual history review
• Blood pressure measurement
• Medication review
• Pregnancy planning
• Cervical screening when due
• Breast health discussion
• Pelvic examination when appropriate
• Contraception counselling
• Sexually transmitted infection testing
• Menopause discussion
• Review of family cancer history

Not every patient needs every examination or screening test during each appointment. Recommendations depend on age, symptoms, pregnancy status, previous results, personal history, and individual risk factors.

Regular women’s health visits also provide an opportunity to discuss concerns that may feel difficult to raise elsewhere, including changes in bleeding, pelvic discomfort, sexual health, urinary symptoms, or reproductive plans.

Preventive gynecology is part of the broader role of regular medical checkups in long-term health.

Pregnancy and Prenatal Care

Prenatal care supports the health of the pregnant patient and the developing baby from early pregnancy through delivery.

Care may involve:

• Confirming the pregnancy
• Estimating the expected delivery date
• Reviewing previous pregnancies
• Checking blood pressure and weight
• Ordering blood and urine tests
• Reviewing medication and supplements
• Monitoring fetal growth
• Discussing ultrasound findings
• Screening for gestational diabetes
• Monitoring for pregnancy complications
• Preparing for labour and delivery

Patients should tell the doctor about previous miscarriages, premature deliveries, cesarean sections, blood pressure problems, diabetes, blood clots, or other pregnancy complications.

Every prescription, over-the-counter medicine, vitamin, and herbal product should be reviewed. A product described as natural is not automatically safe during pregnancy.

High-Risk Pregnancy Monitoring

A pregnancy may require closer monitoring when a health condition or pregnancy-related issue increases risk for the patient, baby, or both.

Reasons for additional monitoring may include:

• High blood pressure
• Preeclampsia
• Gestational diabetes
• Multiple pregnancy
• Previous premature delivery
• Previous pregnancy loss
• Maternal age-related concerns
• Placental problems
• Abnormal fetal growth
• Blood-clotting conditions
• Chronic kidney, heart, or autoimmune disease

Dr. Xydas’s public clinical listings associate his work with high-risk pregnancy, preeclampsia, gestational diabetes, post-term pregnancy, and pregnancy-related anaemia.

Some patients can continue care with their regular obstetrician while receiving additional monitoring. Others may need coordinated treatment with a maternal-fetal medicine specialist.

Preeclampsia and Pregnancy Blood Pressure

Preeclampsia is a pregnancy complication involving high blood pressure and signs that other organs may be affected.

It usually develops after the middle of pregnancy, although related problems may also occur after delivery.

Possible warning signs include:

• Severe or continuing headache
• Vision changes
• Sudden swelling
• Pain beneath the ribs
• Shortness of breath
• Rapid weight gain caused by fluid
• Nausea or vomiting later in pregnancy
• High blood pressure readings

Some patients have few noticeable symptoms, which is why prenatal blood pressure and urine checks are important.

Treatment depends on the stage of pregnancy, severity of the condition, test results, symptoms, and the health of the baby.

Severe headache, vision changes, difficulty breathing, or intense upper abdominal pain during pregnancy should be assessed urgently.

Gestational Diabetes

Gestational diabetes develops when blood sugar becomes elevated during pregnancy.

Many patients do not notice symptoms, so screening is commonly completed during prenatal care.

Management may include:

• Blood sugar monitoring
• Nutrition planning
• Suitable physical activity
• Medication when needed
• Additional fetal monitoring
• Planning the timing of delivery
• Blood sugar testing after pregnancy

Good management can reduce the risk of excessive fetal growth, delivery complications, newborn blood sugar problems, and other concerns.

Having gestational diabetes also increases the likelihood of developing type 2 diabetes later in life. Follow-up testing after delivery remains important even when blood sugar returns to normal.

Anaemia During Pregnancy

Anaemia means the blood cannot carry oxygen as effectively as it should. Iron deficiency is a common cause during pregnancy because the body needs additional iron to support increased blood production.

Possible symptoms include:

• Unusual tiredness
• Weakness
• Dizziness
• Headaches
• Pale skin
• Shortness of breath
• Rapid heartbeat
• Reduced ability to complete normal activities

Blood testing is needed because these symptoms may have several possible causes.

Treatment may involve dietary changes, iron supplements, additional testing, or treatment of another underlying condition. Patients should not begin high-dose iron without medical advice.

Labour and Delivery Planning

Birth planning usually considers the patient’s health, pregnancy progress, fetal position, previous deliveries, and personal preferences.

Topics may include:

• Signs that labour has begun
• When to contact the maternity team
• When to travel to the hospital
• Pain-management options
• Vaginal delivery
• Induction of labour
• Assisted delivery
• Cesarean delivery
• Support people during labour
• Newborn care
• Postpartum follow-up

A birth plan can help patients communicate preferences, but it may need to change when unexpected medical concerns develop.

The main priority during labour is the safety of the patient and baby.

Postpartum Care

Postpartum care begins after delivery and continues as the body recovers from pregnancy and childbirth.

Follow-up may involve:

• Checking recovery after vaginal or cesarean delivery
• Reviewing bleeding
• Assessing blood pressure
• Examining incisions or tears
• Discussing pain control
• Reviewing breastfeeding concerns
• Contraception planning
• Pelvic floor symptoms
• Emotional health screening
• Sleep and family support
• Returning to physical activity

Patients should mention persistent sadness, severe anxiety, panic symptoms, frightening thoughts, or difficulty caring for themselves or the baby.

Physical warning signs such as heavy bleeding, chest pain, severe headache, difficulty breathing, fever, or one-sided leg swelling require prompt assessment.

Menstrual Concerns and Abnormal Bleeding

Menstrual cycles can change because of pregnancy, age, hormone changes, stress, medication, illness, or conditions affecting the uterus and ovaries.

Patients may seek evaluation for:

• Very heavy periods
• Periods lasting longer than expected
• Bleeding between periods
• Bleeding after intercourse
• Missing periods
• Severe menstrual pain
• Irregular cycles
• Bleeding after menopause
• Weakness or dizziness during menstruation

Possible causes include:

• Pregnancy
• Fibroids
• Uterine polyps
• Hormonal changes
• Thyroid conditions
• Polycystic ovary syndrome
• Perimenopause
• Medication effects
• Infection
• Changes in the uterine lining

Evaluation may involve pregnancy testing, blood work, pelvic examination, ultrasound, cervical testing, or sampling of uterine tissue.

Bleeding after menopause should be medically evaluated even when it happens only once.

Pelvic Pain

Pelvic pain may be sudden, recurring, or present for a long period.

Possible causes include:

• Menstrual cramping
• Ovarian cysts
• Fibroids
• Endometriosis
• Pelvic infection
• Bladder conditions
• Digestive problems
• Pelvic floor concerns
• Pregnancy-related complications
• Scar tissue after surgery

Patients should note whether the pain is connected with periods, urination, bowel movements, exercise, pregnancy, or sexual activity.

Describing the location, timing, severity, and character of the pain can help guide the evaluation.

Sudden severe pain with fainting, vomiting, weakness, or pregnancy requires urgent assessment.

Uterine Fibroids

Fibroids are noncancerous growths that develop from the muscular tissue of the uterus.

Some cause no symptoms, while others may lead to:

• Heavy periods
• Pelvic pressure
• Abdominal fullness
• Frequent urination
• Constipation
• Painful menstruation
• Anaemia
• Pregnancy or fertility concerns

Treatment depends on the size and location of the fibroids, symptom severity, age, health, and future pregnancy plans.

Options may include monitoring, medication, minimally invasive procedures, or surgery.

Ovarian Cysts

An ovarian cyst is a fluid-filled or partly solid area that develops on or inside an ovary.

Many cysts are linked with normal ovulation and disappear without treatment.

Further evaluation may be needed when a cyst:

• Causes continuing pain
• Increases in size
• Appears complex on ultrasound
• Develops after menopause
• Causes pressure or bloating
• Is associated with abnormal bleeding

The doctor may recommend repeat ultrasound, blood testing, observation, or surgical consultation depending on the findings.

Cervical Screening

Cervical screening helps identify abnormal cell changes before they become more serious.

Screening may involve:

• A Pap test
• HPV testing
• Both tests together

An abnormal result does not automatically mean that cervical cancer is present.

Further care may include:

• Repeat testing
• Colposcopy
• Cervical biopsy
• Removal of abnormal cells
• Closer monitoring

Patients should provide information about earlier abnormal results, cervical procedures, pregnancy, immune conditions, and HPV vaccination.

Sexually Transmitted Infection Screening

Sexually transmitted infections may cause symptoms, but some infections produce no clear warning signs.

Testing may be appropriate for patients with:

• New sexual partners
• Possible exposure
• Unusual discharge
• Pelvic pain
• Burning during urination
• Genital sores
• Bleeding after intercourse
• Pregnancy
• A partner diagnosed with an infection

Testing may use urine, blood, or vaginal and cervical samples.

Early diagnosis can reduce complications and help prevent transmission. Treatment may also need to include current partners, depending on the infection.

Contraception and Family Planning

Contraception counselling helps patients compare methods according to health, lifestyle, pregnancy goals, and personal preference.

Options may include:

• Birth control pills
• Patches
• Vaginal rings
• Injections
• Implants
• Intrauterine devices
• Barrier methods
• Fertility-awareness methods
• Permanent contraception

No single method is best for everyone.

The doctor may consider blood pressure, migraine history, clotting risk, smoking, menstrual symptoms, medication, and future pregnancy plans.

Patients should ask about effectiveness, expected bleeding changes, possible side effects, and how quickly fertility may return after stopping a method.

Perimenopause and Menopause

Perimenopause is the transition leading to menopause. Hormone levels may change unevenly, causing periods and symptoms to become less predictable.

Possible symptoms include:

• Hot flashes
• Night sweats
• Irregular bleeding
• Sleep problems
• Mood changes
• Vaginal dryness
• Urinary symptoms
• Reduced concentration
• Changes in sexual comfort

Treatment may involve lifestyle support, vaginal moisturizers, local treatment, nonhormonal medication, or hormone therapy for suitable patients.

Hormone treatment is not appropriate for everyone. Personal history, cardiovascular health, clotting risk, breast health, and unexplained bleeding must be considered.
