During pregnancy, women and people assigned female at birth (AFAB) experience physical, hormonal, and emotional changes that can disrupt the body’s natural equilibrium. In addition to bodily changes, lifestyle adjustments and the demands of parenthood can make pregnant women and other people more susceptible to the effects of stress. 
It’s important to understand that while some stress is normal during pregnancy, excessive stress can have negative effects on both the mother and the developing fetus. Therefore, it is crucial to take steps to manage stress during pregnancy. 
To alleviate any concerns you may have, we’re discussing the typical impact of stress on pregnancy and its various effects to equip you with valuable knowledge that can assist you in making informed choices about your own health as well as that of your baby.
If you’ve been diagnosed with post-traumatic stress disorder (PTSD) and are currently pregnant, you may be at an increased risk of preterm birth and low birth rate.1 In fact, pregnant women and individuals diagnosed with PTSD or depression are four times more likely to experience a preterm birth, which occurs when babies are born before the completion of the term. 
Preterm birth is the cause of about two-thirds of infant deaths.  Several types of preterm birth exist, based on the gestational age of the infant: 
PTSD is a type of disorder that develops after experiencing a traumatic or shocking event. Unfortunately, psychological distress can often lead to preterm delivery since it can activate the hypothalamic-pituitary axis—a system of neuroendocrine pathways that help maintain physiological homeostasis. In effect, this may induce birth. 
This stress response may occur for one of two reasons: 
Additionally, the medication that’s prescribed to treat PTSD may also impact the fetus and increase the risk of a preterm delivery.  This is particularly true for pregnant people who began the medications in the second or third term of pregnancy.

Pregnant people who experience anxiety during pregnancy may experience adverse effects on their health, as well as the health of their infant(s). 
Women and people AFAB are more predisposed to mood and anxiety disorders, particularly during their childbearing years. Oftentimes, these disorders can emerge or worsen during pregnancy: At least 10.8% of pregnant individuals have an anxiety disorder. And many pregnant people who experience anxiety also experience symptoms of depression. 
Typically, anxiety disorders are characterized by: 
That said, general anxiety disorders (GAD) can often evolve into pregnancy-related anxiety (PrA). Those with PrA typically experience worries in relation to: 
They may also worry about the effectiveness of certain medical equipment and the skills of their healthcare provider. Post-delivery, these feelings may manifest as anxiety related to their ability to parent or their physical appearance after pregnancy. 
At low levels, stress during pregnancy can help equip the parent for the role of parenting. However, high stress levels can negatively affect the behavior of the parent and may lead to a high-risk pregnancy. 
About 15 to 20% of pregnancies are classified as high-risk, and they often occur in individuals who are over the age of 35. Unfortunately, women and people AFAB of this age are also more predisposed to anxiety. 
As a result, both the mother and the fetus are at higher risk of medical complications, such as:
Sadly, these diagnoses can further exacerbate maternal anxiety levels. 
This occurs when a pregnant person experiences high blood pressure (140/90 mmHg or higher) during pregnancy and is often coupled with: 
Typically, it’s diagnosed around 20 weeks of pregnancy, but symptoms will go away following the birth of the baby. However, it may predispose women and people AFAB to hypertension or other health problems later in life. And it may also negatively impact the fetus, inhibiting its growth and safety within the placenta. 
Gestational diabetes is a type of insulin resistance that can develop during pregnancy.  It affects about 2 to 10% of pregnancies. So why, and how, does this occur?
During pregnancy, the body releases many hormones that cause weight gain, to support the growth of the fetus. As a result, the body is unable to utilize insulin as efficiently as before to deliver glucose to its cells, thus fueling the body. 
This is called insulin resistance. 
Fortunately, gestational diabetes doesn’t have many symptoms in the mother, but it can increase their blood pressure and the chance of having a cesarean section (c-section) during delivery. That said, it can impact the fetus. Babies born to parents with gestational diabetes may: 
When a woman or person AFAB experiences a spike in blood pressure during pregnancy they may experience preeclampsia. Unlike gestational hypertension, preeclampsia occurs in individuals with high levels of protein in the urine. 
About 1 in 25 pregnancies in the United States involve preeclampsia. During their pregnancy, those diagnosed with the condition can experience: 
The condition may also develop into eclampsia, which is characterized by maternal seizures and considered a medical emergency. 
During pregnancy, the placenta—which provides oxygen and nutrients to the baby—may lie very low within the uterus, covering the opening of the cervix completely or partially.
In effect, a pregnant person with this condition may experience bleeding during and after pregnancy. 
In some pregnancies, the placenta may detach partially or completely from the uterus. For the infant, this may result in: 
Alternatively, those carrying the baby may experience: 
Stress during pregnancy can affect the growth of the fetus. More specifically, fetal growth restriction (FGR) can occur. As a result, infants will weigh less than the 10th percentile in their gestational age category. 
Unfortunately, FGR can lead to several short and long-term complications that may impact the child’s quality of life. These include but are not limited to: 
Also called cervical insufficiency, cervical incompetence can lead to premature birth or the loss of a pregnancy, due to weak cervical tissue. More specifically, the cervix may begin to open too soon over the course of each trimester. 
While it’s difficult to diagnose this condition before it occurs, people who are pregnant can look for some signs of the condition, which include: 
Although it can be challenging to cope with negative moods and anxiety while pregnant, it is crucial for the well-being of both you and your baby to address and manage these emotions. Oftentimes, this involves multidisciplinary approaches to care for maternal anxiety and its related conditions: 
Stress experienced by pregnant individuals can have a significant impact on their well-being, as well as the well-being of their developing baby. As such, it’s critical that pregnant people regularly monitor their physical and emotional health to ease feelings of anxiety during pregnancy.
