Medically necessary consultations, prenatal care, delivery, gynecological surgeries, and diagnostic procedures performed by a licensed Obstetrician and Gynecologist like Dr. Ou are generally covered by Ontario Health Insurance Plan (OHIP) in ON when you have a valid referral from your family doctor or another referring physician. Some elective procedures, certain fertility treatments, or non-medically indicated services may not be covered.

Do I need a referral from my family doctor to see Dr. Ou, an Obstetrician and Gynecologist?

Yes, for services to be covered by your provincial health plan (Ontario Health Insurance Plan (OHIP)), a referral from your family physician or another specialist is typically required to see an Obstetrician and Gynecologist like Dr. Ou for most consultations and treatments. This ensures coordinated care. Some specific services or clinics (e.g., some sexual health or contraception clinics) might have different access pathways, but for ongoing obstetrical or gynecological care, a referral is standard. Please check with Dr. Ou's office or your referring doctor.

What are the treatment options for endometriosis that Dr. Ou might recommend?

Treatment for endometriosis aims to manage pain and improve fertility if desired. Options vary based on symptom severity and patient goals and can include pain medications (NSAIDs), hormonal therapies (like birth control pills, progestins, GnRH agonists) to suppress endometrial tissue growth, and surgical treatments (laparoscopy) to remove endometrial implants and scar tissue. Dr. Ou will discuss the most appropriate approach for your situation.

When should a teenager have her first OBGYN visit, and what does it involve?

The first visit to an OBGYN for a teenager is often recommended between ages 13-15, or sooner if there are specific concerns like very painful periods, irregular cycles, or questions about sexual health. This initial visit may not involve a pelvic exam unless there's a specific medical reason. It's primarily an opportunity to build a rapport with Dr. Ou, discuss normal development, menstrual health, contraception, STI prevention, and answer any questions in a confidential setting.

What are my options for pain management during labor discussed by Dr. Ou?

Dr. Ou will discuss various pain relief options for labor, which can range from non-medical methods (like breathing techniques, movement, massage, hydrotherapy if available) to medical options such as nitrous oxide, narcotic pain medication, and epidural anesthesia. The choice depends on your preferences, medical condition, and the progress of your labor. It's a good idea to discuss your pain management plan with Dr. Ou during your prenatal visits.

How often do I need a Pap test, and what is it for?

A Pap test (or Pap smear) is a screening procedure for cervical cancer. It checks for precancerous or cancerous cells on the cervix. Guidelines vary slightly by province but are generally recommended for women starting around age 21-25 (or once sexually active) and continuing every 2-3 years if results are normal. The frequency may change based on your age, medical history (including HPV status), and previous Pap test results. Dr. Ou will advise you on the appropriate screening schedule for your individual circumstances based on current provincial guidelines.

What is an IUD insertion like? Does Dr. Ou perform this?

Yes, Dr. Ou can perform IUD (Intrauterine Device) insertions in the office. The procedure involves placing a small, T-shaped device into your uterus for long-acting, reversible contraception. During the insertion, you might experience some cramping, similar to period pains. Dr. Ou can discuss pain management options, such as taking an over-the-counter pain reliever beforehand or using local anesthetic in some cases. The actual insertion usually takes only a few minutes. He will ensure the procedure is as comfortable as possible and provide guidance on what to expect before and afterward.
