Currently, in the world, one in every 80 pregnancies is a double pregnancy (twins or twins), while one in 8,000 is a triple pregnancy (triplets), and one in 1,000,000 is a quadruple pregnancy (quadruplets). There are several mechanisms that can lead to the gestation of several babies in the womb at the same time.

The most frequent is multigygotic, which appears in 70 percent of multiple pregnancies. It results when two or more eggs are fertilized by two or more sperm, creating different eggs (multi-gothic). Less common are monozygotic multiple pregnancies, which account for 30 percent of multiple pregnancies and result from the division of an egg into two or more identical (monozygotic) eggs. A multiple pregnancy is a high-risk pregnancy.

A woman's body has to make an effort to adapt to this overload, which involves:

- Arterial hypertension. It occurs in 15-20 percent of pregnant twins. Preeclampsia or hypertension appears earlier and is sometimes more difficult to control with commonly used medications.

- Gestational diabetes. Gestational diabetes appears in 5-10 percent of cases.

- Moderate-severe anemia. It occurs in 40 percent of multiple pregnancies, and requires postpartum transfusion in 5 percent of cases.

- Caesarean section. It should be done in 50-85 percent of cases, depending on the centers, because the fetal positions other than cephalic that babies adopt at birth increase in multiple deliveries.

- Premature delivery. The average duration of double pregnancies is 37 weeks. There are no verifiable statistics for more than two babies.

- Postpartum hemorrhage. The wide placental area and the highly distended uterus put the mother at risk for bleeding after delivery.

- Spontaneous abortion. Spontaneous loss of one or more fetuses is more common in multiple pregnancies. The risk of pregnancy loss also increases in the other trimesters.

The risks derive mainly from prematurity (birth before the 35th week of gestation) and from intrauterine growth retardation.

- Premature. 19 percent of twins or twins are premature. Low-weight babies, especially those born before 32 weeks gestation and / or those weighing less than 3 1/3 pounds (1,500 grams), are more likely to develop health problems in the immediate aftermath of their birth as well as permanent disabilities, such as mental retardation, cerebral palsy, and loss of vision and hearing.

- Growth retardation. In 30 percent of twin pregnancies, growth retardation occurs in one of the twins, and in both in 15 percent of pregnancies.

- Perinatal mortality. This is the name given to death between 5 months of gestation and 10 weeks of life. It is multiplied by 6 in multiple pregnancies. In single pregnancies it is 5 per 10,000, and in twins it is 30 per 10,000 pregnancies.

- Congenital defects. Multiple pregnancy babies are at twice the risk of congenital (present at birth) abnormalities including neural tube defects (such as spina bifida), gastrointestinal and heart defects.

- Fetal transfusion syndrome. It is a disorder of the placenta that develops only in identical twins who share the placenta. Blood vessels connect within the placenta and divert blood from one fetus to the other. It happens in almost 15 percent of twins who share the placenta.

- Abnormal amounts of amniotic fluid. They are more common in multiple pregnancies, especially for twins who share a placenta.
