About Dr. Deya J. Dafashy

Dr. Dafashy completed his medical education at Cairo University’s Faculty of Medicine. He later continued postgraduate medical training in the United States.

His professional records list transitional training through the University of Chicago and obstetrics and gynecology residency training at Indiana University Medical Center.

This education prepared him to provide preventive, medical, obstetric, and surgical care involving the female reproductive system.

Dr. Dafashy’s clinical interests extend beyond routine obstetrics and gynecology. His practice highlights fertility care, tubal surgery, menopause management, pelvic-floor disorders, uterine fibroid treatment, urinary leakage, and minimally invasive surgery.

His approach may involve reviewing symptoms, completing a pelvic examination, requesting blood tests or imaging, prescribing medicine, performing an office procedure, or discussing surgery when conservative treatment does not provide enough improvement.

Obstetrics and Gynecology Services

Dr. Dafashy may provide care involving:

• Well-woman examinations
• Pap tests and cervical screening
• Contraception
• Pregnancy confirmation
• Prenatal care
• Labour and delivery
• Postpartum care
• Infertility evaluation
• Tubal-ligation reversal
• Menstrual disorders
• Abnormal uterine bleeding
• Uterine fibroids
• Pelvic pain
• Ovarian cysts
• Endometriosis
• Menopause care
• Hormone-replacement therapy
• Pelvic organ prolapse
• Urinary incontinence
• Minimally invasive gynecological surgery

The recommended assessment depends on the patient’s age, symptoms, previous treatment, pregnancy history, reproductive plans, and general medical health.

Well-Woman Examinations

A well-woman visit provides an opportunity to review preventive and reproductive health.

The appointment may include:

• Updating the medical history
• Reviewing menstrual cycles
• Discussing current symptoms
• Measuring blood pressure
• Reviewing medication and supplements
• Performing a pelvic examination when appropriate
• Assessing cervical screening needs
• Discussing breast health
• Reviewing contraception
• Discussing fertility or pregnancy plans
• Reviewing menopause symptoms

Not every patient requires every examination or test during each visit.

Recommendations should be based on age, symptoms, previous findings, medical risks, and current screening guidance.

Patients should mention unusual bleeding, pelvic pressure, vaginal discomfort, urinary changes, abnormal discharge, or pain during sexual activity.

Cervical Cancer Screening

Cervical cancer screening helps identify abnormal cell changes before they develop into a more serious condition.

Screening may involve:

• A Pap test
• Human papillomavirus testing
• Combined Pap and HPV testing
• Follow-up after an abnormal result
• Colposcopy when appropriate
• Cervical biopsy when necessary

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

Many findings represent mild cell changes or an HPV infection that may clear naturally. The next step depends on the type of change, HPV result, age, medical history, and previous screening results.

Contraception and Family Planning

Dr. Dafashy may help patients compare contraceptive methods according to effectiveness, convenience, possible side effects, and future pregnancy plans.

Options may include:

• Birth control pills
• Contraceptive injections
• Intrauterine devices
• Contraceptive implants
• Skin patches
• Vaginal rings
• Barrier methods
• Fertility-awareness methods
• Tubal ligation

Some hormonal methods may also help manage heavy periods, painful menstruation, acne, or irregular cycles.

Patients should discuss migraines, high blood pressure, tobacco exposure, previous blood clots, medication, and family medical history before choosing hormonal contraception.

Pregnancy and Prenatal Care

Prenatal care allows Dr. Dafashy to monitor the health of the pregnant patient and developing baby.

Care may include:

• Pregnancy confirmation
• Initial prenatal assessment
• Review of previous pregnancies
• Laboratory testing
• Blood pressure monitoring
• Ultrasound coordination
• Fetal heartbeat assessment
• Fetal growth monitoring
• Gestational diabetes screening
• Prenatal genetic-screening discussions
• Labour and delivery planning

Appointments generally become more frequent as pregnancy progresses.

Additional monitoring may be needed when a patient has high blood pressure, diabetes, thyroid disease, previous pregnancy complications, multiple pregnancy, abnormal fetal growth, or placental concerns.

Labour and Delivery Planning

Delivery planning may cover:

• Signs of labour
• When to contact the hospital
• Pain-management choices
• Induction of labour
• Vaginal delivery
• Cesarean delivery
• Fetal monitoring
• Recovery after childbirth

The safest delivery approach depends on fetal position, placental location, labour progress, maternal health, previous uterine procedures, and fetal well-being.

A patient’s preferences remain important, but the plan may need to change if an unexpected medical concern develops.

Postpartum Care

Postpartum appointments support recovery after childbirth.

Dr. Dafashy may review:

• Postpartum bleeding
• Recovery after vaginal delivery
• Recovery after cesarean delivery
• Incision or tear healing
• Pelvic discomfort
• Blood pressure
• Urinary symptoms
• Return to normal activity
• Menstrual changes
• Postpartum contraception
• Breast and feeding concerns

Recovery differs according to the delivery method, pregnancy complications, medical history, sleep, and available help at home.

Infertility Evaluation

Infertility may involve ovulation, the uterus, fallopian tubes, sperm health, age, or several factors occurring together.

Dr. Dafashy has a stated clinical interest in fertility care.

An initial evaluation may include:

• Menstrual history
• Ovulation patterns
• Previous pregnancies
• Earlier pregnancy losses
• Medication review
• Pelvic examination
• Hormone testing
• Pelvic ultrasound
• Assessment of the uterus
• Assessment of the fallopian tubes
• Partner testing

The timing of testing depends on age, cycle regularity, known medical conditions, and how long pregnancy has been attempted.

Some patients can receive initial treatment through a general OB-GYN practice. Others may need referral to a reproductive endocrinologist or fertility centre.

Tubal-Ligation Reversal

Tubal-ligation reversal is an operation intended to reconnect sections of the fallopian tubes after previous sterilisation.

Dr. Dafashy’s practice highlights tubal-reversal surgery as an area of clinical focus.

The possibility of successful reconstruction depends on:

• The original sterilisation method
• Amount of healthy tube remaining
• Location of the blocked area
• Age
• Egg supply
• Other fertility factors
• Partner fertility
• Previous pelvic surgery
• Scar tissue

Not every patient is a suitable candidate.

The surgeon may need to review the previous operative report to understand whether clips, rings, burning, removal, or another method was originally used.

Tubal-Reversal Consultation

During a tubal-reversal consultation, Dr. Dafashy may review:

• The reason for previous sterilisation
• Current pregnancy goals
• Previous pregnancy history
• Age and menstrual regularity
• Earlier pelvic operations
• Original tubal-ligation records
• General medical health
• Fertility test results
• Partner testing
• Alternative fertility treatments

Patients should understand that reconstructing the tubes does not guarantee pregnancy.

Success depends on several medical and reproductive factors. Pregnancy achieved after tubal surgery may also require early monitoring because of an increased risk of implantation outside the uterus.

Tubal Surgery and Pregnancy Planning

Patients considering tubal surgery may compare it with assisted reproductive treatment.

Tubal reversal may allow the possibility of more than one pregnancy without repeating fertility treatment each time. However, it requires an operation and depends heavily on the remaining tubal anatomy.

Assisted reproduction may avoid reconstructive tubal surgery but involves its own medicines, procedures, costs, and medical considerations.

The better option differs between patients.

A careful evaluation should consider age, ovarian reserve, semen testing, desired family size, tubal condition, surgical risks, and available financial resources.

Menstrual Disorders

Menstrual cycles may change because of hormonal shifts, pregnancy, medication, stress, thyroid disease, uterine conditions, or the transition toward menopause.

Dr. Dafashy may evaluate:

• Heavy periods
• Painful menstruation
• Irregular cycles
• Missed periods
• Bleeding between periods
• Prolonged bleeding
• Bleeding after sexual activity
• Bleeding after menopause

Testing may include pregnancy testing, blood work, pelvic examination, ultrasound, cervical screening, hysteroscopy, or sampling of the uterine lining.

Treatment depends on the cause and may involve medicine, hormonal therapy, an intrauterine device, an office procedure, or surgery.

Abnormal Uterine Bleeding

Abnormal uterine bleeding describes bleeding that is heavier, longer, more frequent, or less predictable than expected.

Possible causes include:

• Hormonal changes
• Uterine fibroids
• Uterine polyps
• Thyroid disease
• Pregnancy-related conditions
• Medication effects
• Perimenopause
• Blood-clotting disorders
• Changes in the uterine lining

The evaluation may involve laboratory testing, pelvic ultrasound, cervical screening, hysteroscopy, or endometrial biopsy.

The treatment plan should consider the cause, degree of blood loss, age, medical history, and pregnancy goals.

Uterine Fibroids

Uterine fibroids are noncancerous growths that develop within or around the uterus.

They may cause:

• Heavy menstrual bleeding
• Prolonged periods
• Pelvic pressure
• Abdominal fullness
• Painful menstruation
• Frequent urination
• Constipation
• Back discomfort
• Anemia
• Fertility concerns

Many fibroids do not cause symptoms and may only require observation.

Dr. Dafashy’s practice lists several fibroid-related procedures and treatment options. The most suitable approach depends on fibroid size, location, number, symptoms, age, and future pregnancy plans.

Fibroid Treatment Options

Fibroid care may include:

• Continued observation
• Medicine
• Hormonal treatment
• An intrauterine device
• Hysteroscopic removal
• Fibroid ablation
• Myomectomy
• Uterine artery embolisation
• Hysterectomy

Each treatment has different effects on fertility, menstruation, recovery, and the possibility of fibroids returning.

Patients who want a future pregnancy should discuss how each option could affect the uterus and reproductive plans.

Hysteroscopic Fibroid Removal

Hysteroscopy uses a narrow camera passed through the cervix to examine the inside of the uterus.

Fibroids that grow into the uterine cavity may sometimes be removed through the hysteroscope without abdominal incisions.

This approach may be considered when a fibroid contributes to:

• Heavy bleeding
• Bleeding between periods
• Anemia
• Fertility concerns
• Repeated pregnancy loss
• Abnormal ultrasound findings

The suitability of hysteroscopic removal depends on the fibroid’s position, depth, and size.

Myomectomy

Myomectomy removes uterine fibroids while preserving the uterus.

It may be considered for patients who have:

• Heavy bleeding
• Pelvic pressure
• Significant pain
• Anemia
• Fertility concerns
• Distortion of the uterine cavity

The procedure may be performed through hysteroscopic, laparoscopic, robotic, or open surgical techniques.

The approach depends on the number, size, depth, and location of the fibroids.

Fibroids can return after myomectomy because the operation removes existing growths but does not prevent new ones from forming.

Ovarian Cysts

Ovarian cysts are fluid-filled sacs that form on or inside an ovary.

Many are connected with normal ovulation and disappear without treatment.

Some may cause:

• Pelvic discomfort
• Pressure
• Bloating
• Menstrual changes
• Pain during activity
• Discomfort during sexual activity

Dr. Dafashy may use pelvic ultrasound to evaluate a cyst’s size, appearance, and location.

Management may include observation, repeat imaging, medication, or surgery. An operation may be considered when a cyst causes significant symptoms, continues growing, or has unusual imaging features.

Endometriosis

Endometriosis occurs when tissue similar to the uterine lining grows outside the uterus.

Possible symptoms include:

• Painful periods
• Continuing pelvic pain
• Pain during sexual activity
• Digestive symptoms linked with menstruation
• Heavy bleeding
• Difficulty becoming pregnant

Evaluation may involve medical history, pelvic examination, imaging, and sometimes minimally invasive surgery.

Treatment may include pain medicine, hormonal therapy, laparoscopic treatment, fertility support, or a combination of approaches.

Pelvic Organ Prolapse

Pelvic organ prolapse develops when weakened support tissues allow the bladder, uterus, vagina, rectum, or another pelvic structure to move downward.

Dr. Dafashy lists prolapse as one of his clinical interests.

Possible symptoms include:

• Vaginal pressure
• A feeling of heaviness
• A visible or noticeable bulge
• Symptoms that worsen while standing
• Difficulty emptying the bladder
• Incomplete bowel movements
• Lower-back pressure
• Discomfort during sexual activity

Treatment depends on which organs are affected and how strongly the condition interferes with everyday life.

Prolapse Treatment

Treatment options may include:

• Observation
• Pelvic-floor exercises
• Pelvic-floor physical therapy
• A vaginal pessary
• Treatment of constipation
• Activity adjustments
• Vaginal tissue treatment
• Reconstructive surgery

A pessary is a removable device placed inside the vagina to support prolapsed structures.

Surgery may be considered when symptoms remain disruptive or conservative care does not provide enough improvement.

Patients seeking subspecialist pelvic-floor care may also review Dr. Hilaire W. Fisher’s urogynecology profile.

Urinary Incontinence

Urinary incontinence means urine leaks when the patient does not intend it to.

Dr. Dafashy’s practice lists urinary incontinence among his areas of care.

Stress Urinary Incontinence

Stress urinary incontinence causes leakage during activities that increase abdominal pressure.

These may include:

• Coughing
• Sneezing
• Laughing
• Running
• Jumping
• Lifting
• Exercise

Treatment may involve pelvic-floor therapy, a vaginal support device, an office procedure, or surgery.

Urgency Urinary Incontinence

Urgency incontinence involves a sudden need to urinate followed by leakage.

Patients may also experience frequent urination, nighttime urination, and difficulty reaching the toilet in time.

Treatment may include bladder training, medicine, pelvic-floor therapy, or more advanced bladder treatment.

Menopause Care

Menopause is the stage when menstrual periods permanently stop. Symptoms may begin earlier during perimenopause.

Dr. Dafashy has a stated interest in menopause and hormone-replacement therapy.

Patients may seek care for:

• Hot flashes
• Night sweats
• Irregular periods
• Sleep disruption
• Vaginal dryness
• Discomfort during sexual activity
• Urinary changes
• Mood changes
• Bone-health concerns

Treatment may involve practical daily adjustments, non-hormonal medicine, vaginal therapy, or menopausal hormone treatment when medically appropriate.

Hormone-Replacement Therapy

Menopausal hormone therapy may reduce hot flashes, night sweats, and selected vaginal symptoms.

It is not suitable for every patient.

Before recommending treatment, Dr. Dafashy may review:

• Age
• Time since menopause began
• Symptom severity
• Uterine status
• Previous blood clots
• Stroke risk
• Heart disease
• Breast health history
• Unexplained vaginal bleeding
• Liver conditions
• Current medicines

The type, dose, and route of treatment should be selected according to individual needs and risks.

Patients should attend follow-up appointments so symptoms, blood pressure, bleeding patterns, and medicine effects can be reviewed.

Minimally Invasive Gynecological Surgery

Dr. Dafashy’s listed services include laparoscopic and robotic gynecological procedures.

Minimally invasive surgery uses small incisions, a camera, and specialised instruments.

It may be considered for selected cases involving:

• Uterine fibroids
• Ovarian cysts
• Endometriosis
• Pelvic adhesions
• Abnormal bleeding
• Pelvic pain
• Prolapse
• Hysterectomy

Potential benefits may include smaller incisions, less postoperative discomfort, and a shorter recovery than traditional open surgery.

Not every condition or patient is suitable for this approach.

Robotic Gynecological Surgery

Robotic surgery is a form of minimally invasive surgery in which the surgeon controls specialised instruments from a surgical console.

It may provide:

• Magnified three-dimensional viewing
• Precise instrument movement
• Access through small incisions
• Greater movement in confined pelvic areas

The robot does not perform the operation independently. The surgeon remains in control throughout the procedure.

Suitability depends on the diagnosis, previous surgery, anatomy, medical health, and complexity of the planned operation.

Total Laparoscopic Hysterectomy

A total laparoscopic hysterectomy removes the uterus and cervix through small abdominal incisions.

It may be considered for selected patients with:

• Severe abnormal bleeding
• Symptomatic fibroids
• Continuing pelvic pain
• Endometriosis
• Adenomyosis
• Uterine prolapse
• Precancerous changes
• A condition not improving with conservative treatment

The ovaries are separate from the uterus and are not automatically removed.

Before surgery, patients should discuss whether the ovaries and fallopian tubes will remain and how this decision may affect hormone function and future health.

Vaginal Natural-Orifice Surgery

Dr. Dafashy’s listed services include vaginal natural-orifice transluminal endoscopic surgery, commonly known as vNOTES.

This minimally invasive approach uses the vagina as the access route for selected gynecological operations.

Potential features may include:

• No visible abdominal incision
• Endoscopic visualisation
• Removal of the uterus or other selected procedures
• A recovery plan based on the extent of surgery

Not every patient is a suitable candidate.

Previous surgery, uterine size, pelvic anatomy, infection history, prolapse, and the reason for treatment can influence whether this approach is appropriate.

Preparing for a Gynecology Appointment

Patients can prepare by bringing:

• A current medication list
• The date of the last menstrual period
• Previous Pap test results
• Pregnancy and delivery history
• Earlier surgical records
• Tubal-ligation operative records
• Recent laboratory reports
• Ultrasound or imaging results
• A list of medicine allergies
• Notes about current symptoms
• Questions about testing or treatment

Patients experiencing abnormal bleeding may find it helpful to record when it occurs, how long it lasts, and how heavy it becomes.

Those seeking fertility or tubal-reversal care should bring previous operative reports whenever available.

Preparing for Gynecological Surgery

Preparation may include:

• Blood tests
• Urine testing
• Pregnancy testing when relevant
• Medication review
• Anaesthesia assessment
• Heart testing when appropriate
• Diabetes management
• Treatment of active infection
• Instructions about food and drink
• Transportation arrangements
• Planning for help at home

Patients should provide complete information about prescriptions, non-prescription medicines, vitamins, supplements, and allergies.

Blood thinners and some diabetes medicines may require special instructions. Patients should not stop prescribed medicine without guidance.

Recovery After Gynecological Surgery

Recovery depends on the procedure, surgical approach, general health, and whether several treatments were completed together.

Instructions may cover:

• Incision care
• Vaginal bleeding or discharge
• Pain management
• Walking
• Lifting restrictions
• Driving
• Returning to work
• Exercise
• Sexual activity
• Follow-up visits

Patients may feel better before internal tissues have fully healed.

Following activity restrictions can help protect healing areas and lower the chance of complications.

Telemedicine Appointments

Dr. Dafashy’s current practice lists telemedicine for suitable appointments.

A virtual visit may be useful for:

• Reviewing laboratory results
• Discussing stable symptoms
• Medication follow-up
• Menopause treatment review
• Contraception discussions
• Fertility planning
• Preparing for a procedure
• Follow-up after earlier treatment

Pelvic examinations, Pap tests, ultrasound, biopsies, and surgical procedures require an appropriate in-person setting.

Multilingual Women’s Healthcare

Dr. Dafashy speaks English, Arabic, and Spanish.

Multilingual communication may help patients:

• Describe personal symptoms clearly
• Understand testing instructions
• Discuss pregnancy concerns
• Review fertility options
• Understand medicine use
• Ask questions about surgery
• Participate in treatment decisions

Patients should confirm language availability when arranging an appointment, particularly when interpretation support is needed.

Coordinated Women’s Healthcare

Obstetric and gynecological conditions may require cooperation with:

• Primary care physicians
• Maternal-fetal medicine specialists
• Fertility specialists
• Urogynecologists
• Urologists
• General surgeons
• Radiologists
• Pathologists
• Pelvic-floor physical therapists

Coordination is especially important when a patient has infertility, prolapse, urinary symptoms, major fibroids, or several previous pelvic operations.

Patients researching another obstetrician and gynecologist may also review Dr. Dawn D. Black’s women’s healthcare profile.

Patient-Centered Obstetric and Gynecological Care

Dr. Dafashy provides women’s healthcare based on each patient’s age, symptoms, medical history, pregnancy needs, test results, fertility plans, and personal treatment goals.

His clinical services may include preventive examinations, prenatal care, infertility evaluation, tubal-reversal consultation, fibroid treatment, menopause care, prolapse management, urinary incontinence assessment, and minimally invasive gynecological surgery.

Patients should confirm appointment availability, accepted insurance plans, telemedicine eligibility, hospital participation, surgical locations, fertility services, and referral requirements directly with Women’s OB/GYN Center.
