Do I need a referral from my family doctor to see Dr. Vastis, 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. Vastis 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.

I have uterine fibroids. What treatment options might Dr. Vastis suggest?

Treatment for uterine fibroids depends on their size, number, location, and the severity of your symptoms (like heavy bleeding or pain), as well as your reproductive goals. Options range from watchful waiting for asymptomatic fibroids, to medications (hormonal therapies to manage symptoms), to minimally invasive procedures (like uterine artery embolization - often by interventional radiology), or surgical removal of fibroids (myomectomy) or the uterus (hysterectomy). Dr. Vastis will help you decide the best course of action.

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. Vastis, 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. Vastis?

Dr. Vastis 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. Vastis during your prenatal visits.
