Important Yet Overlooked: Placenta Health

Though the placenta plays an extremely important role in human development, it isn’t talked about all that much. The placenta is an organ that develops within the uterus during pregnancy, and is delivered vaginally following child birth. Some say a healthy placenta is the most important component of developing a healthy baby—this is because it plays a few key roles. One is that it brings oxygen and nutrients to the developing baby through the umbilical cord. Another is that it takes away waste away from the baby’s blood. Third, the placenta plays a role in providing immune protection to developing babies.

Placenta Health

A healthy placenta is crucial to a healthy pregnancy, but the health of your placenta can be affected by numerous factors such as blood pressure, blood clotting disorders, maternal age (for example, problems with the placenta are more common in women who are older than 40), trauma to the abdomen, substance misuse, and a history of uterine surgery. Women with placenta problems may experience signs and symptoms like abdominal pain, heavy vaginal bleeding, uterine contractions, and back pain.

Some of the most common placenta-related medical conditions include:

  • Placental abruption, where the placenta separates from the inner wall of the uterus before delivery and can deprive the baby of oxygen and nutrients. This condition may also cause heavy bleeding in the mother.
  • Placenta previa, in which the placenta sits very low in the uterus and partially or fully covers the cervix. This condition is common in the earlier parts of pregnancy and can involve very heavy bleeding.
  • Placenta accreta, where parts of the placenta grow deeply into the uterine wall, often leading the placenta to remain attached to the uterine wall after childbirth.

It can be difficult to prevent placenta problems, but there are a few things you can do to minimize your risk and work towards a healthy pregnancy. One of the most important things you can do is to see your healthcare provider regularly to maintain your overall health and to manage any existing conditions that may potentially affect the health of your placenta.

The placenta is the least studied of all human organs, but in recent years there’s been an abundance of new research. Here are a few noteworthy projects related to placenta health that may lay the groundwork for gathering new information about the role of the placenta in human health and development:

  • Researchers at the National Institute of Child Health and Human Development (NICHD) have been working on the the Human Placenta Project, which aims to understand more about the role that the placenta plays in the health of mothers and children, as well as in the development of disease throughout each stage of pregnancy. You can read more about the project
  • Scientists have been developing miniature, lab-grown placentas to learn more about conditions like stillbirth, pre-eclampsia, intrauterine growth restriction, and miscarriage. These lab-grown placentas are also being used in other interesting and important ways such as studying how infections like Zika impact unborn babies. In the future, they may be even be used to check the safety of drugs taken during pregnancy and to see how hormones may indicate if a placenta isn’t functioning properly and is at risk for complications.
