When the placenta is positioned low in the uterus, covering or partially covering the cervix, it can cause a condition known as placenta previa. While you may not always be comfortable with this, knowing the specifics will help you prepare. When the placenta is joined to the anterior wall, or front portion of the uterus, there is a variation of this condition.
Previa indicates that the placenta is covering or close to the cervix, which could lead to complications, when it is on the anterior wall. However, as the uterus grows and the placenta shifts upward, many cases of placenta previa, especially those that occur early in pregnancy, may resolve on their own.
It’s critical to be aware of the symptoms and to maintain regular communication with your doctor. Even though placenta previa on the anterior wall can be concerning, there are numerous effective ways to monitor and manage this condition with modern prenatal care.

What is it?
- Location of the placenta on the anterior wall of the uterus. The placenta is most often located closer to the bottom of the uterus, namely along the front (less often, back) wall, and this is the norm.
- Placenta previa.
There is no such thing as "placenta previa on the anterior wall of the uterus."
We will go into more detail about placenta previa below, as it is not the norm for the placenta to be located on the anterior wall of the uterus.
There must be a full blood flow to maintain the chorion’s and the fetus’s vital activity. Through the network of uteroplacental arteries, the baby can get all the nutrients and oxygen it needs. They ensure the growth and development of the fetus by passing through the placenta in large quantities.
The primary natural roles of placental tissue are to supply nutrition and shield the developing embryo from outside threats. The placenta’s location affects the fetus’s development inside the uterus. The fetal growth’s intensity at a given stage of pregnancy is dictated by its movements.
The placenta’s attachment style affects the baby’s intrauterine development intensity. In actuality, the placental tissue’s attachment is predetermined from the very beginning of pregnancy. The location of the placental tissue is determined by the location of the fertilized egg’s implantation.
The placenta is usually found near the fundus of the uterus, either on the anterior or posterior wall. In certain instances, it may also be found to the left or right of the side walls. Placental tissue has the ability to adhere to multiple uterine walls simultaneously if it is abundant.
The placenta’s physiological location is easily explained. The uterine fundus and its posterior wall have a highly well-expressed blood supply. This facilitates the rapid and intense growth of the fetus.
Nature has a purpose in determining the placenta’s normal attachment. This configuration offers greater benefits for the fetus’s intrauterine growth.
Different areas of the uterus can receive placental tissue attachments. On the other hand, in some circumstances, placental tissue is laid down lower, in the lower segment of the uterus. The development of placental tissue’s presentation is complicated by its too-low location.
When the placental tissue is near the internal os of the uterus, placenta presentation is regarded as pathological. They are usually separated by a certain amount of space. As a result, placental tissue normally exceeds the internal os by 5–7 cm in the second trimester, depending on the data. A pathological state is referred to as presentation if there is a noticeable reduction in this distance.
Physicians discern between multiple clinical variations in the presentation of placental tissue. As a result, the placenta may present lateral, marginal, or central.
Why does this happen?
The placenta’s attachment is established from the very beginning of pregnancy. This is a very easy process. The fertilized egg starts to descend lower because it is unable to adhere to the bottom of the uterus for some reason. Thus, it almost reaches the internal os, where it is inserted.
Placenta previa can arise as a result of several gynecological conditions. Damage is caused to a woman’s reproductive organs by chronic inflammation. The mucous membrane lining the uterus’s interior changes in this instance. The fertilized egg’s ability to attach in the lower sections is facilitated by these modifications.
The placenta may attach itself in the lower regions of the uterus and in cases where the mother has had several gynecological procedures. Therefore, the development of this kind of presentation may be influenced by curettage or the aftereffects of surgical abortions.
Physicians have observed that women who have given birth again have a slightly higher risk of developing placenta previa. There is a multiplex increase in the likelihood of anterior placental tissue presentation in women with a burdened obstetric-gynecological history.
Numerous congenital diseases of the reproductive organs may also contribute to the development of this issue. Women with uterine hypoplasia may experience placental presentation. The development of this pathology can also be attributed to anatomical defects of the uterine structure.
Placenta previa, or the placenta covering part or all of the cervix, is a condition that can cause problems during pregnancy. It is located on the anterior wall of the uterus. This condition frequently necessitates close medical supervision and can result in bleeding, particularly in its later stages. As the pregnancy goes on, many cases resolve on their own, but in order to protect the mother and unborn child, some may require medical attention or a cesarean section.
Features of this location
Presentation of the placenta is less physiological. There are advantages and disadvantages to this placement of placental tissue. There are far fewer benefits than drawbacks in this situation.
It should be mentioned that a specific medical strategy is needed in such a clinical setting. The doctors must watch with some attention behind a pregnant woman with such a placenta arrangement.
Pros
One benefit of placenta previa is the potential for migration. The placental tissue may move during the several months that pass before the baby is born.
Cons
Placenta abruption frequently happens with placenta previa. In this instance, risky uterine bleeding may arise as a result of abdominal trauma. Should it become excessively strong, the fetus may experience acute oxygen starvation, posing a serious risk to its survival.
Is placenta migration possible?
Migration is defined as a shift in the placenta’s original location. Experts surmise that placenta previa may cause a shift in the placental tissue’s localization. When doctors advise pregnant women, they usually warn them about this.
First and foremost, the expectant mother should not become alarmed if placenta previa is discovered in the early stages of pregnancy. The time until labor is still quite far off. The placental tissue may move during this period, possibly changing its position considerably.
Ultrasound is used to evaluate such alterations. Typically, physicians order multiple follow-up ultrasound exams to monitor the dynamics. Vaginal exams shouldn’t be done frequently if placental tissue is visible. It is crucial to monitor the dynamics of the placental tissue’s location during presentation. It aids medical professionals in quickly recognizing emerging issues and implementing the required actions to make things better.
It is important to remember that the placental tissue typically moves slowly. For the female body, it is ideal if this process takes place in 6–10 weeks. It is unlikely that the expectant mother will feel any significant discomfort in this situation. By the middle of the third trimester of pregnancy, placental tissue migration usually comes to an end completely.
Adverse effects can also happen if the placental tissue moves too quickly for whatever reason. The two most hazardous ones are when bleeding starts and the placental tissue separates from the uterine wall. Generally, adverse symptoms arise if placenta migration takes place within a week or two. The placental tissue’s initial location at a given height is one of several factors that affect the placenta’s migration rate.
Consequences
The most serious side effect of placenta previa is placental abruption and bleeding. It is noticeable if it is strong enough. The woman in this instance detects the appearance of blood coming from the genital area. Both the amount and color of the bleeding can differ, ranging from bright red to dark brown. The most important thing to keep in mind in this case is that women with placenta previa should call an ambulance right away if such a bloody discharge appears.
On ultrasonography, placental abruption appears as a hematoma when it occurs without any bloody discharge from the genital tract. But this also poses a risk to pregnancy and needs to be treated.
The development of bleeding is possibly the most dangerous complication with a low placenta and presentation. It is noticeable if it is strong enough. In this instance, a woman observes that blood is emerging from her genital area. Both the amount and color of the bleeding can differ, ranging from bright red to dark brown. The most important thing to keep in mind in this case is that women with placenta previa should see an obstetrician-gynecologist right away if such a bloody discharge appears.
An additional complication that may arise during such a pregnancy is placental abruption. The degree to which the placenta has detached from the uterine wall determines the severity of the disorders that develop in this situation.
Only an ultrasonography can identify detachment if this region is small. In this instance, the woman might not even have any genital tract bleeding at all, or if she does, it might be so slight as to be overlooked.
Because severe placental abruption disrupts the fetus’s overall condition, it can also be dangerous. When the fetus’s oxygen supply is disrupted, hypoxia, or oxygen starvation, sets in. Usually, this kind of situation leads to a change in the fetus’s clinical indicators. Its heart rate and motor activity, for instance, vary dramatically.
The pregnant patient needs to be admitted to the hospital right away if severe placental abruption occurs. The duration of pregnancy will determine the subsequent course of medical treatment.
Doctors will have no choice but to use emergency obstetrics if there is an excessive risk to the mother’s or the fetus’ life. Vital signs are taken into account when performing it.
| Term | Explanation |
| Placenta Previa | When the placenta is located low in the uterus and covers part or all of the cervix, blocking the baby"s way during birth. |
| Anterior Wall | This means the placenta is attached to the front side of the uterus, closer to the belly. |
A natural delivery is more difficult when there is placenta previa on the anterior wall of the uterus because the placenta is positioned low and covers the cervix’s opening. For the duration of pregnancy, this condition needs to be closely monitored.
Although this may sound alarming, many cases end as the pregnancy goes on. The placenta may migrate away from the cervix as the uterus grows, lowering the risk.
Healthcare professionals will talk about safe delivery options if the placenta is still low later in pregnancy. They will frequently advise a cesarean section to avoid complications.
In order to manage this condition and ensure the health of both mother and unborn child throughout the pregnancy, routine checkups and open communication with your doctor are crucial.
