There are multiple ways to make patients feel more comfortable during these procedures.
3 things I offer everyone:
1. Cytotec (misoprostol)- This is an oral medication you’ll take the night before and the morning of which helps to soften your cervix.
2. High dose ibuprofen 30 minutes before
3. Anti-anxiety medication like Xanax 30 minutes before

Let’s talk about the cervical block. This is injected lidocaine into four quadrants of the cervix. A cervical block can numb the cervix and the lower part of the uterus, but it does not numb the portion of the uterus where the IUD is placed. While a typical IUD procedure takes 2 minutes, this additional procedure can take another 5 minutes. It also requires a ~4 inch spinal needle —The needle alone can cause patient severe anxiety. Also, the procedure of injecting those four quadrants can be quite painful. We can do this, but you should know the facts!

IUDs can be placed under sedation or general anesthesia in the operating room after thorough counseling. We do not have anesthesiologists or sedation equipment in the office - so this is done in an OR setting.
Other things I have and will try/have tried:
- hurricane spray/spraying lidocaine on the cervix
- Inserting lidocaine into the endometrial canal

One other thing I have changed in the last few years is not using a tenaculum on the cervix. This is a sharp instrument that we used to use to grab the cervix and help maneuver the IUD into the correct position. I find that using a different type of softer clamp is much less uncomfortable for the patient and still gets the job done. It doesn’t cause any bleeding as it doesn’t poke holes in the cervix like a tenaculum does.
I have definitely changed my practice since I first started out in private practice 9 years ago. I am always trying to learn the best practices and make any procedures easier for my patients.
I truly believe the faster the procedure is, the better. You need someone quick (who does these a lot). The use of distraction is also key!

Turning 40 this year really brought perimenopause to the forefront for me. I also have at least 10-15 patients ask me about this a week, so I’m invested into educating and continued learning about this topic!

It’s a tough subject for many reasons, which I’ll breeze through a few below. Just know, I am committed as much as you to getting to the bottom of this!

🔥 There is no true ‘definition’ of perimenopause, like there is for menopause 12 months with no periods)
🔥There is no test to determine if you are in, going through, or meeting perimenopause.
🔥 While there are many reasons to test your hormones, testing them in this phase of life is not helpful —- what IS helpful is reviewing your symptoms with your doc, and treating them one by one. This is difficult to grasp for some (mainly because there are all these companies testing your hormones—but the reality is at the core of this, we’re all using the same treatments! So shouldn’t this be tailored to SYMPTOMS and not NUMBERS?)
🔥 Nearly every woman’s symptoms are different. There is lots of overlap, but most symptoms vary in frequency and severity.

What’s the peanut ball for?
🥜 the peanut ball has been used for decades during labor
🥜 positioning it between the legs helps to widen the pelvis and mimic the patient in an upright position, which can be more helpful for the fetus to descend in the pelvis
🥜 some studies have shown it can help reduce maternal pain in labor
🥜 one study showed a decreased length of the 1st stage of labor

Your labor and delivery nurse will often whip out the peanut ball when your labor is not progressing or we think the baby is not in the right position for descending into the pelvis. You can use it at any point in labor though.

There is no risk to using the peanut ball!

Did you use it during labor?

To check or not to check…
🌇This is the scenario: you are 36 weeks, you get undressed for the GBS swab, and your doc asks if you want your cervix checked.

▪️A cervical check is when the doctor does a manual pelvic exam (similar to the exam done during a wellness visit) to determine if the cervix is dilated and/or effaced. We can also feel for the position of the baby (but a quick ultrasound can also confirm this). The exam can be uncomfortable for some, while others may not be bothered at all.

🔹 Most importantly, you do not ever need your cervix checked unless we need to determine if you’re in labor. Period. That’s it.

You may WANT your cervix checked, and here is why:
🔸 You want to know if you are dilated, effaced, or if the head is low. Some mom’s want to know this at every weekly visit and some don’t care.

🔹If someone wants their cervix checked just once, I often recommend this to be done at the last visit before an induction (if an induction is needed). I can guide the patient more accurately on how the induction may proceed (ie. what medications we may use) depending on the last cervical exam. But again, this is not required.

⭐️Note: a cervical exam is NOT a membrane sweep. Please see previous post regarding membrane sweeps.

It is time for my yearly mammogram. I am considered high risk for a few reasons.

Did you know we can help determine your personal breast cancer risk?
👩🏻‍💻There are multiple calculators which can help us determine this risk.
👩🏻‍💻 One reason to do this is because it may change the way we recommend screening you for breast cancer.
👩🏻‍💻 The tests give us percentages, lifetime risk and yearly risk, of developing breast cancer.
👩🏻‍💻 If your lifetime risk is greater than 20%, we would likely recommend alternating between MRI and mammogram every 6 months.
👩🏻‍💻There is no perfect way to predict someone’s risk of developing breast cancer, and there are some situations in which these calculators are not useful.

One of the most common surgeries I perform is called a hysteroscopy. I do these for many different reasons on women of all ages. This week I did a hysteroscopy to remove a uterine polyp.
📍Uterine polyps are very common - they are overgrowths of uterine/endometrial tissue
📍The majority of these are not cancerous or even pre-cancerous, but there is a small chance of malignancy in patients who have abnormal bleeding, are postmenopausal, are on tamoxifen, or have a genetic predisposition to uterine cancer.
📍The procedure to remove them is usually very simple. I place a camera through the cervical opening and use a device that quickly shaves them away. The whole process usually takes less than 15 minutes.
📍Where I work, these are performed under general anesthesia.

It’s cervical cancer awareness month!
Let’s debunk some common myths.

1️⃣ You should not have a paper smear until you are 21.

2️⃣ Pap smears are NOT yearly*. Paps should be done every 3 years from age 21-29 and every 5 years starting at age 30. *as long as they are normal

3️⃣ If you have had the HPV vaccine, this does not prevent you from getting all forms of HPV (it may prevent progression of dysplasia and it can prevent you from getting forms of HPV you have not already aquired). And if you haven’t had this vaccine, talk to your OBGYN about getting it (no matter how old you are!!). The current HPV vaccine vaccinates against 9 virulent strains of the virus.

⏺️ While you might not be getting a Pap smear each year, you should still see your OBGYN yearly. You will still get a pelvic exam (speculum and bimanual) as we still need to look at the vagina/cervix and feel the uterus/ovaries, etc.

🩵 🗓️ September is Ovarian Cancer Awareness Month

Ovarian cancer affects 3% of women and is the 5th leading cause of cancer related deaths in women.

Unfortunately, the ability to effectively screen for ovarian cancer is quite limited. We have found, though, that there are some ways to reduce the risk of ovarian cancer.

Tubal ligation, a procedure for permanent sterilization, has been shown to decrease a person’s risk of ovarian cancer by up to 33%. Traditionally, this procedure was performed by removing a small piece of the middle section of the fallopian tube.

More recently we have learned that the most common type of ovarian cancer actually originates at the ends of the fallopian tubes. By removing the entire fallopian tubes— a procedure called bilateral salpingectomy— we can (further?) reduce ovarian cancer rates without adding time or risk to the procedure.
