One of the most common unforeseen events in a pregnancy is the placenta previa or placenta inferior. The placenta is the baby’s support throughout pregnancy. Through the placenta the baby receives all the nutrients needed to grow strong and healthy.
The flow of blood that the placenta provides contains both food and oxygen to the fetus, and it begins to form at the same time that the fetus is implanted in the uterus. The blastocyst ( baby in formation ) divides into two parts, one will become the placenta and the other the baby . The problem is when the placenta lodges and settles in a complicated place for pregnancy.
What is Placenta Prévia?
The placenta previa is characterized by its location lower in the uterus. The ideal place for the placenta to be would be at the top of the uterus and in some cases it is located below very close or on top of the cervix which would make normal delivery very difficult.
The low placenta may initially settle below, but with the passage of pregnancy and with the growth of the uterus it rises and is located correctly. If up to the 20th week the placenta still shows a partial preview, there is still time for it to rise and locate correctly.
Types of Previous Placenta
There are three types of low or previous placenta, each with its own risks and particularities at different stages. The types of placenta previa are:
- Marginal placenta: Type of placenta previa that only approaches the cervix and does not offer any obstacle or major problem for the pregnant woman. This type of placenta previa does not prevent normal delivery from happening.
- Partial placenta: The type of placenta previa that partially covers (one piece) the cervix. This type of placenta can actually prevent a normal delivery.
- Total placenta: The type of placenta previa that most concerns doctors about childbirth and other problems that a placenta previa can bring. In this case, the placenta completely covers the cervix and, even with the growth of the uterus, was not brought up in its location.
Causes of Previous Placenta
The low / previous placenta happens without apparent causes, it simply develops in unwanted places, but some factors contribute to it happening. Twin pregnancy, where there would be more than one placenta ; many previous pregnancies , uterine different format ( bicornuate or septate eg.), curettage poorly made which could result in scars or endometriosis removal surgery.

The main problem that the placenta previa brings to the pregnant woman, really is at the time of delivery, if she opts for a normal delivery and has a total low placenta, for example, she would be unable to give birth in a natural way. Another problem that the placenta previa causes is bleeding.
They can happen at any stage of pregnancy and a simple movement of the baby can cause bleeding from the placenta. Some cases of placenta previa or low placenta are more delicate than others and these are recommended to rest to help contain bleeding.
If still the rest is not enough, the hospitalization of the pregnant woman can happen for more ostensible monitoring . Some women may have placenta previa during pregnancy and not even notice! In fact, most cases only receive confirmation of the diagnosis on imaging exams (ultrasound) .
The placenta previa or low placenta poses no greater risk to either the mother or the baby. If there is a lot of bleeding during pregnancy, the doctor must support the pregnant woman. However, most cases of placenta previa resolve up to 36 weeks of gestation without any action being taken.

My name is Dr. Alexis Hart I am 38 years old, I am the mother of 3 beautiful children! Different ages, different phases 16 years, 12 years and 7 years. In love with motherhood since always, I found it difficult to make my dreams come true, and also some more after I was already a mother.
Since I imagined myself as a mother, in my thoughts everything seemed to be much easier and simpler than it really was, I expected to get pregnant as soon as I wished, but it wasn’t that simple. The first pregnancy was smooth, but my daughter’s birth was very troubled. Joana was born in 2002 with a weight of 2930kg and 45cm, from a very peaceful cesarean delivery but she had already been born with congenital pneumonia due to a broken bag not treated with antibiotics even before delivery.
