Causes of a thin placenta during pregnancy and the consequences of hypoplasia

The placenta is essential to the growth and development of the fetus during pregnancy. It serves as a mother’s and child’s lifeline, supplying vital nutrients and oxygen and eliminating waste. But occasionally, the placenta doesn’t grow as planned, which can result in hypoplasia, also known as a thin placenta.

For expectant mothers, it is essential to comprehend the causes of a thin placenta. Smoking, high blood pressure, and certain medical conditions are some of the factors that can exacerbate this problem. It is imperative to attend to these risk factors in order to facilitate a healthy pregnancy and reduce the likelihood of complications.

A thin placenta can have effects on the fetus as well as the mother. Reduced blood flow and nutrient supply due to a thin placenta may have an effect on the baby’s growth and development. In order to guarantee the best possible outcome for mother and child, it is imperative to monitor and manage this condition.

The common causes of placental thinning and its possible effects on pregnancy will be discussed in this article. We’ll also talk about ways to control and lessen these risks in order to encourage a healthier pregnancy experience.

What is it?

• Primary hypoplasia. Associated with an initially disrupted process of implantation of the fertilized egg to the wall of the uterus due to certain reasons. In this situation, from the very first days of pregnancy, the placental tissue is small. The functioning of the organ is usually impaired.
• Secondary hypoplasia. In this case, the initial formation of the placental tissue was correct, and all the changes appeared later. Adverse symptoms with secondary hypoplasia usually appear not in the earliest stages, but already in the second half of pregnancy.

Placental hypoplasia, the term for a thin placenta that develops during pregnancy, can be caused by a number of things, including inadequate maternal nutrition, elevated blood pressure, or underlying medical disorders. Serious repercussions for the mother and child may result from this condition, such as impaired fetal growth, preterm birth, or difficult delivery. In order to manage and mitigate risks and ensure a healthier pregnancy outcome for both mother and child, it is imperative to understand the causes and potential impacts of a thin placenta.

Causes

Researchers have identified a number of causal factor groups that may play a role in the development of hypoplasia of the placental tissue. The factors that contribute to the development of this pathology are unique to each unique case.

Genetics

Physicians discuss potential genetic causes of primary placental hypoplasia, which can result in a fetus with a variety of diseases. Combination pathologies can arise as a result of these factors in certain situations. As a result, in addition to placental hypoplasia, the fetus may also develop different body abnormalities and abnormalities in the structure of the umbilical cord.

It is highly recommended that women with a family history of genetic diseases seek advice from a geneticist regarding the risk of developing these pathologies while pregnant.

It is preferable to take this action when you are getting ready to become pregnant. It might also be required to pass multiple laboratory genetic tests.

The impact of external factors

These elements typically start to work while the placenta is still forming. It should be mentioned that aggressive environmental factors can have a significant impact on placental tissue. The effects of external factors on the placenta that is actively forming can be extremely detrimental if the expectant mother has any concurrent diseases or a sharply compromised immune system.

The results of different bacterial, viral, or fungal infections can also lead to the development of hypoplasia. The inflammatory response that an infection causes in a pregnant woman’s body has an impact on placental tissue formation, potentially disrupting its development. In this situation, the placenta typically develops slowly and experiences disruptions to its full function.

Vascular pathologies

Pregnancy-related arterial hypertension is one of the aggravating factors that puts placental hypoplasia development at risk. If the expectant mother experiences gestosis during her pregnancy, it is extremely unfavorable. The development of various unfavorable symptoms in this case considerably aggravates the course of the pregnancy.

Damage to blood vessel walls happens in gestosis and persistent arterial hypertension (high blood pressure). Because it alters the rate and degree of placental tissue development, this condition during placenta formation is extremely dangerous. Excessive duration of hypertension is another factor that leads to the placenta’s failure to function.

In addition, the following vascular pathologies may influence the development of placental hypoplasia:

• various vasculitis;
• atherosclerosis;
• autoimmune pathologies occurring with a vascular component;
• congenital anomalies in the development of connective tissue.

Diagnostics

Placental hypoplasia during pregnancy can be identified using contemporary ultrasound diagnostic techniques. With this pathology, ultrasounds are typically done multiple times during pregnancy. This enables medical professionals to monitor the degree to which the placenta’s thickness varies during gestation.

Physicians also recommend Doppler sonography when they want to make sure that the level of uteroplacental blood flow is understood. This technique can also be used to inferentially evaluate the child’s body’s oxygen and nutrition intake. Similar to ultrasound, dopplerography is typically recommended dynamically.

In actuality, placental hypoplasia is sometimes detected as late as weeks 30-32 of pregnancy. A "find" like this prompts doctors to closely monitor the expectant mother.

When a patient has placental hypoplasia, medical professionals must evaluate the unborn child’s overall health. To do this, medical professionals measure the fetus’s heart rate and assess its motor activity.

For the sake of the mother’s and the unborn child’s health, it is imperative to comprehend the causes and effects of a thin placenta during pregnancy. Deficits in certain nutrients or high blood pressure can cause a thin placenta, which can affect the fetus’s ability to receive vital nutrients and oxygen. Complications from this could have an impact on the baby’s growth and development.

Underdevelopment of the placenta, or hypoplasia, is a serious concern because it can result in inadequate fetal growth and raise the possibility of preterm birth. To monitor placenta health and address any issues early on, routine prenatal checkups are essential. When a condition is identified, medical professionals can offer advice on how to treat it and increase the likelihood of a successful pregnancy.

In the end, even though a thin placenta poses difficulties, prompt medical attention can help reduce the risks and support the mother and the unborn child. Pregnancy safety and health can be ensured in large part by keeping yourself informed and collaborating closely with healthcare professionals.
