If you are pregnant, you must have heard of placenta previa, which is one of the possible complications of pregnancy. But where does this complication come from and how serious is it? Placenta previa occurs when the placenta is in an abnormal position and partially or completely covers the cervix. - The most obvious symptom: discharge of bright red blood without pain. - The most common risk factors: previous cesarean delivery and age (under 20 years or over 35 years). In most cases, placenta previa can be managed and result in normal delivery.

What is a pair? Before we dive into the running pair in detail, let's take a step back and check out the amazing pair. Because its origin is actually an incredible feat: your body creates an entirely new (and temporary) organ designed specifically to support the growing fetus! Although its function is complex, the placenta essentially acts as a two-way filter between mother and baby, connecting the fetus and the uterine wall through the umbilical cord. As blood flows through the uterus, the placenta absorbs nutrients, oxygen, and immune molecules and delivers them to the fetus. Then, when waste products and carbon dioxide build up in the baby's blood, they are transferred back into your blood, which filters them out. The placenta is formed during implantation. Specifically, when a sperm fertilizes an egg, a structure called a blastocyst forms. When this blastocyst implants in the wall of your uterus, the inner part of this structure becomes the embryo and the outer part becomes the placenta.

What is a pair? Normally, the placenta adheres to the uterine wall so that it does not block the cervix. But sometimes it sits near or above the cervix. This can lead to various problems such as dangerously low blood pressure, bleeding and premature birth. When the placenta is inserted too low, it may also detach from the uterine wall. When this happens, the placenta is no longer able to support the baby until birth. In such cases, your doctor may recommend a cesarean delivery.

How often does mating happen? The good news is that this is relatively rare, occurring in 1 in 200 pregnancies. If placenta previa is detected early in pregnancy, there is no need to worry because most of these early cases will resolve on their own without intervention. What are the different types of placenta? **There are three types of pairs:** - Central (totally covering) hiatus that completely blocks the internal system of the cervix. - A partial hernia that only partially obstructs the internal system of the cervix. - A marginal passage that reaches into the cervix but does not cover it. What causes placenta previa? While the exact causes of placenta previa are unknown, it is believed to be due to scarring of the uterus or endometrium. This scar may be caused by a previous caesarean section or uterine fibroid removal. What are the symptoms of placenta previa? The most noticeable signs of placenta previa are sudden, bright red bleeding that occurs late in pregnancy, mostly around the 32nd week. **Other symptoms that can be recognized are:** - Premature contractions The good news is that most cases of placenta previa resolve on their own, especially if caught early. As your uterus grows, it may push the placenta away from the uterine lining like a balloon. However, if the placenta completely covers the uterine lining, or if the diagnosis occurs late in pregnancy, it is less likely to resolve naturally.

These risk factors include: - History of placenta previa History of caesarean section or other surgical procedures on the stomach or cervix - Under 20 or over 35 years old Having a multiple pregnancy, breech delivery or delivery in an inappropriate position. Usually, the placenta is removed from the uterine wall after the birth of the baby. However, if the placenta covers or blocks the internal system, it may rupture, bleed, or cause life-threatening bleeding in the mother. If the placenta is damaged or ruptured, you may experience light red, painless bleeding. In such a case, your doctor will perform an ultrasound to determine the source of the bleeding.

How is the unpaired pair recognized? The best way to diagnose placenta previa is to do an ultrasound. Transvaginal ultrasound is recommended because its results are much more accurate than those of the abdominal wall. Ultrasound determines the actual distance from the edge of the placenta to the inner cervix near the baby. If the interval is too short, a follow-up examination is recommended for the third trimester.

How is ectopic pregnancy treated? Before labor begins, rest is often recommended in cases of placenta previa. But sometimes, when excessive bleeding occurs, you need to go to the hospital, the best place to get blood and quickly treat problems like anemia. Your doctor must consider several factors to determine how to proceed: your age, the health and length of the pregnancy, the health of the fetus, whether the placenta has begun to separate from the uterine wall. The goal of your treatment is to reduce bleeding and the risk of preterm labor. Some doctors recommend staying in bed, although the effectiveness of this method has not been fully proven. While some women with partial or marginal placenta previa can deliver naturally, cesarean delivery is often the best option for expectant mothers with central placenta previa.
