What to Expect

For women both directly before and during pregnancy, nothing is more important than proper medical care. Prenatal care has been proven to reduce the chance of maternal death, miscarriage, and birth defects. Your obstetrician can detect and treat any medical problems before complications occur, and refer you to other specialists when necessary.

If you are considering becoming pregnant or suspect you are pregnant, see Dr. Ayalon for a healthcare checkup to ensure your child will be healthy. You should tell Dr. Ayalon about any medications you are taking, as some may be harmful to your child’s development and may need to be substituted. The more your OBGYN knows about your current health the better he can help your prepare for what to expect during pregnancy and delivery.

c-section birth








With the advances of obstetrics, more women are choosing a c-section birth as their delivery option.  There are many benefits to a c-section for both mom and baby but it does not always mean it is better than having a vaginal birth.  Since a c-section is major surgery, it is important to consult with your obstetrician to better understand what to expect during and after the procedure.

What to Expect

A cesarean section is a common surgical procedure performed on pregnant women who cannot safely give birth the natural way. These can be planned in advance or become necessary due to complications during labor. Other complications that could necessitate a cesarean section include displaced placenta, mother or child distress, halted labor, non-dilated cervix, compressed umbilical cord, and oxygen cut off to the baby.

The procedure involves making a horizontal incision in the lower abdomen through which the baby is lifted out. The umbilical cord is cut and the fetal membranes are removed. The surgeon will then stitch the uterus and abdominal wall closed. In most cases, Dr. Ayalon will use spinal anesthesia, which will cause the patient to not feel any pain. If the situation is an emergency, general anesthesia may be used.

If you feel a c-section birth may be right for you, please contact your obstetrician in Tarzana to learn more about the surgery.  Dr. Ayalon desires to provide compassionate and understanding professional care for all his patients when making birthing decisions.


postpartum depression


With the rise in understanding of postpartum depression, it is a positive step in offering mothers the necessary support to heal emotionally and physically after having a baby.  For mothers who find themselves feeling overwhelmed or anxious,  it is essential for them to know what they are experiencing is completely normal.  By visiting your OBGYN in Tarzana CA, you can identify if what you are feeling is postpartum depression and what steps you need to take to get the help necessary to begin to feel more like yourself and bond with your child.

Common Signs of Postpartum Depression

Women suffering from postpartum depression might be easily agitated, restless, feel worthless or guilty, are unable to enjoy most activities, and may even have thoughts of death or suicide. Symptoms will vary, with some women worrying excessively about their baby while others show little interest in them. In severe cases, some mothers feel urges to hurt their baby, but this is very rare and these feelings are almost never acted upon. Generally, symptoms are persistent and cause you to feel negative about your baby or your life situation after delivery.

Common Causes of Postpartum Depression

If you are pregnant and any of these apply to you, remember that stress from these scenarios can play a part in postpartum depression:

• Having depression or bipolar disorder before pregnancy
• Having mixed feelings about the pregnancy
• Abusing alcohol, illegal substances, or smoking during pregnancy
(this behavior is harmful to your baby and should not continue during or after pregnancy)

• Being a single mother or having a weak relationship with your partner
• Experiencing complications during delivery

The most important thing to remember when experiencing postpartum depression is that you are not alone.  You have your family, your doctor, and other medical professionals who can help you through this time. We encourage all our patients who think they may be experiencing symptoms of depression to schedule an appointment with your OBGYN in Tarzana.

flu shot during pregnancy


Should I get a flu shot while pregnant?

Not only is it safe, but it is also essential that pregnant women get the flu shot because of the changes in their bodies that make them prone to infection. Once you are 32 weeks into your pregnancy your immune system is suppressed to protect your fetus from being rejected from your body. This leaves pregnant women susceptible to many illnesses like the flu.

Can I get the flu nasal spray during my pregnancy?

Pregnant women should only receive the shot and never the nasal spray vaccine. The shot contains an inactive virus while the nasal spray uses a live virus which is riskier for pregnant women and women trying to become pregnant. Check with your doctor before getting the shot if you have had any severe reactions in the past. While some reactions are not related to the shot, it is always good to take extra precautions. You may need to wait in Dr. Ayalon’s office for at least thirty minutes after receiving a shot in order to monitor your reactions.

What are the risks of not getting a flu shot when pregnant?

Catching the flu during your pregnancy is cause for concern since your suppressed immune system increases the severity of flu symptoms. A case of the flu in pregnancy can lead to pneumonia, hospitalization, or even death. During pregnancy, your heart and lungs are put under extra stress, and your immune system will not work as hard to rid your body of the virus. The flu can affect your baby as well, causing complications like low birth weight, preterm birth, and miscarriage.

What additional actions can I take to prevent catching the flu?

Aside from getting the vaccination for you and your baby, make sure that anyone living with you receives the shot as well. Your family and others living with you are going to be in close contact with you and your newborn. You can take other preventative actions to protect yourself against catching the flu as well. Prenatal vitamins containing Vitamin C help strengthen your immune system. Don’t forget to consume your vitamins and minerals naturally through a well-balanced diet, making sure to eat plenty of fruits and vegetables.

What if I get the flu while pregnant?

If you happen to catch the flu during your pregnancy, increase your fluids intake, eat small meals spread throughout the day, get plenty of rest, and use a steamer to help facilitate ease of breathing. Make sure to monitor your temperature at least once a day and call your OBGYN in Tarzana if your temperature gets close to 100° F or if you are concerned about your symptoms.
