Amniocentesis

The majority of expectant parents want to ensure their baby is as healthy as possible. Along with pre-genetic tests that determine certain genetic traits or risks parents may pass to their offspring, prenatal testings are quite common. These help you carry a healthy pregnancy to term, and check in on the baby’s health. Amniocentesis is one of these prenatal tests: it diagnoses genetic disorders and other health issues in a fetus:

  • Fetal infection can be determined through amniocentesis, along with other illnesses 
  • Fetal lung testing is rarely done, but if a delivery is planned to happen sooner than 39 weeks amniotic fluid helps see if a baby’s lungs are mature enough for birth
  • Sometimes there is an amniotic fluid build-up in the uterus–polyhydramnios–and it is drained through amniocentesis

What is the procedure?

It is normal to be nervous about any medical procedure, much more so if you are pregnant! The goal of amniocentesis is to extract amniotic fluid from your uterus, and most procedures happen between 15-20 weeks of gestation. Here’s what you should expect on the day of your appointment:

  1. You will lie on your back, just like you would prepare for a routine ultrasound. That’s the first step, as the ultrasound will show where your baby is in your uterus that particular day and time. 
  2. The ultrasound will remain on screen as your healthcare provider inserts a very thin needle through your stomach wall and into the uterus. The needle is removed swiftly as amniotic fluid is drawn into the syringe. 
  3. There is no sedation or numbing used, and it is important that you stay still. Even after the needle is removed, the ultrasound will remain in use to monitor your baby’s heart rate. 
  4. You may experience mild cramping during the procedure, and/or shortly after, but you should be able to resume your normal activities after the test. 

When is it necessary?

As one of many prenatal testings, amniocentesis provides details on certain genetic conditions and issues that other procedures may not fully address. It can detect chromosomal, genetic disorders, or congenital disabilities such as down syndrome, Tay-Sachs disease, neural tube defects, and Rh disease. 

If the results of a routine prenatal screening test are worrisome, your doctor may suggest amniocentesis to rule out another diagnosis. If you’ve had a pregnancy with a genetic condition, amniocentesis will look for that condition in your current pregnancy. If the parents are carriers of a genetic condition, or have a family history, amniocentesis shows whether your baby is affected by it. Unusual ultrasound findings are another reason for further testing. Babies born to people over 35 have a higher risk of chromosomal conditions, so if you’ve had a prenatal cell-free DNA screening that came back positive, amniocentesis will shed light into possible conditions. 

Even if your doctor suggests amniocentesis, and explains why, the final decision is up to you; as with any healthcare issue, you always have the right to seek out other professional opinions!

Uterine Fibroids

If you have a uterus, then you already know there are countless issues to keep in mind and a full maintenance schedule for your uterine health. There is yet another concept to add to your list: uterine fibroids. Ideally, your OBGYN or primary care doctor has already talked to you about these. But if this is the first time you come across this term, fear not–uterine fibroids are extremely common, and 99% of the time they are also harmless. However, that does not mean you should ignore them, or that they don’t contribute their fair share of challenges in your cycle. 

What are uterine fibroids and how do I know I have them?

Uterine fibroids, also known as leiomyomas, are quite simple: they are noncancerous growths (or tumors, though that word is admittedly scary) made up of the connective tissue and muscle from the wall of the uterus. They can grow solo, or in a cluster, and are most commonly less than 8 inches in diameter– though they can grow larger. Many people with a uterus do not even realize they have uterine fibroids, unless some of the symptoms start becoming more prominent, or you specifically ask your OBGYN to look for them. 

The most common signs of uterine fibroids include heavy menstrual bleeding, periods lasting more than a week, bleeding between your periods, frequent urination or difficulty emptying your bladder–usually resulting in a feeling of heaviness in your lower abdomen–constipation, lower back pain, and even pain during sex. These symptoms are definitely not an exclusive list, and presence of such symptoms does not guarantee the only issue is uterine fibroids: if you have concerns, it is advised that you consult with your doctor so you can know exactly what you are dealing with. 

How are they diagnosed and treated?

If you are concerned about the presence of uterine fibroids, you can ask to have an ultrasound done to determine the presence of uterine fibroids. The ultrasound can be transabdominal, and/or be done inside your vagina to get pictures of the uterus. Your doctor may also order blood count tests to determine if you have anemia from chronic blood loss, and to rule out other bleeding disorders. If these methods do not yield satisfactory results, there are more in depth tests that your OBGYN can order, such as an MRI, hysterosonography, or hysteroscopy. 

Since uterine fibroids are benign, the recommended treatment–as long as they are not causing significant issues in your day to day life and do not interfere with your fertility–is to keep an eye on them. They rarely grow and do not tend to interfere with fertility and/or pregnancy, and also tend to shrink after menopause. There are possible medications that your doctor may prescribe, medication which control your hormone levels to create menopause-like conditions. This tricks the fibroids into thinking your body has entered menopause, and causes them to shrink along with their unpleasant effects (such as heavy bleeding). Though there are procedures available as well, this is a step you would discuss at length with your doctor.
