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. Chang's office or your referring doctor.

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

Yes, Dr. Chang 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. Chang 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.

What are some common gynecological surgeries Dr. Chang might perform?

Common gynecological surgeries include procedures like hysterectomy (removal of the uterus), oophorectomy (removal of ovaries), tubal ligation (female sterilization), D&C (dilation and curettage), endometrial ablation, and surgeries to treat conditions such as fibroids (myomectomy), endometriosis, ovarian cysts, or pelvic organ prolapse. Many of these can be performed using minimally invasive techniques like laparoscopy or hysteroscopy. Dr. Chang will discuss if surgery is appropriate for your condition and explain the specific procedure, risks, and benefits.

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

Dr. Chang 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. Chang during your prenatal visits.

Does Dr. Chang manage high-risk pregnancies?

Many OBGYNs manage a range of pregnancies, including some with moderate risk factors. If your pregnancy is considered high-risk due to specific maternal or fetal conditions, Dr. Chang will provide comprehensive care and may work closely with, or refer you to, a Maternal-Fetal Medicine (MFM) specialist if needed for highly specialized management. It's best to discuss your specific situation with Dr. Chang.

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. Chang will advise you on the appropriate screening schedule for your individual circumstances based on current provincial guidelines.
