Are services from Dr. Grisdale, an Obstetrician and Gynecologist, covered by Ontario Health Insurance Plan (OHIP) in ON?

Medically necessary consultations, prenatal care, delivery, gynecological surgeries, and diagnostic procedures performed by a licensed Obstetrician and Gynecologist like Dr. Grisdale 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. It's always recommended to confirm specific coverage details with Ontario Health Insurance Plan (OHIP) or the clinic.

Do I need a referral from my family doctor to see Dr. Grisdale, 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. Grisdale 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. Grisdale's office or your referring doctor.

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

Yes, Dr. Grisdale 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. Grisdale 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.

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

Does Dr. Grisdale discuss or offer the HPV vaccine?

The Human Papillomavirus (HPV) vaccine is highly effective in preventing infections with HPV types that cause most cervical cancers, as well as other anogenital and oropharyngeal cancers. Dr. Grisdale can discuss the benefits of the HPV vaccine, current recommendations for different age groups (including catch-up vaccination for adults), and can either provide the vaccine or refer you to where it can be obtained, depending on clinic services and provincial programs.

I have uterine fibroids. What treatment options might Dr. Grisdale 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. Grisdale will help you decide the best course of action.
