Intrauterine growth retardation (IUR) is a serious pathology manifested in the slowdown of fetal growth and development during pregnancy. This anomaly can occur at various stages of gestation and can be caused by many factors, including genetic, material and exogenous effects. IUR is diagnosed when the fetus's weight and size are significantly lower than normal values, which can lead to a number of complications in both the perinatal and postnatal periods. Critical consequences of this pathology include premature birth, as well as an increased risk of chronic diseases in newborns.
History of the disease and interesting historical facts
Intrauterine growth retardation has a long history, as evidenced by medical reports and studies dating back to ancient times. The first mentions of fetal growth retardation can be found in the writings of Hippocrates, who emphasized the influence of the mother on the condition of the fetus. In the 20th century, with the development of medical imaging technologies and prenatal diagnostic methods, the attention of specialists to IUGR has increased significantly. Interesting facts about the disease also include the development of a fetal growth scale based on its size and weight, which made it possible to more accurately determine the presence of pathology.
Epidemiology
Statistics show that IUGR is one of the main causes of infant and perinatal mortality. According to the World Health Organization, approximately 15% of newborns have low birth weight, which is often associated with intrauterine growth retardation. It should also be noted that the prevalence of this pathology varies depending on the region, socio-economic situation and level of medical care. According to recent studies, in developing countries the level of IUGR can reach 30%, while in wealthier regions this figure is at the level of 5-7%.
Genetic predisposition to this disease
Intrauterine growth retardation can be associated with various genetic abnormalities. Studies of the genes and mutations involved have shown that some of them may be critical for normal fetal growth and development. For example, mutations in genes responsible for the synthesis of proteins important for cell proliferation can lead to serious consequences. It is also known that chromosomal abnormalities such as Down syndrome and other structural genetic disorders are often accompanied by developmental delay.
Risk factors for the development of this disease
There are many risk factors that contribute to the development of intrauterine growth retardation. These include:
- Physical factors: chronic diseases of the mother (hypertension, diabetes), deficiency of essential microelements in the body (for example, iron and folic acid).
- Chemical factors: exposure to toxic substances and diseases such as syphilis, HIV, etc.
- Socioeconomic factors: low level of education and lack of access to health care have a significant impact.
- Shame and stigma surrounding pregnancy at a young age.
These factors can interact with each other and significantly increase the risk of developing IUGR in the fetus.
Diagnosis of this disease
Diagnosis of intrauterine growth retardation is based on an assessment of clinical signs, laboratory and instrumental studies.
- The main symptoms are: fetal growth retardation, low birth weight, asymmetric development detected by ultrasound examination.
- Lab tests: hormone tests, prenatal tests for infections and genetic abnormalities.
- Radiological examinations: ultrasound examinations that allow us to assess the size of the fetus and its condition.
- Other diagnostics include using magnetic resonance imaging (MRI) to evaluate structural abnormalities.
- Differential diagnosis: Be aware of other possible diagnoses such as congenital anomalies or chromosomal disorders.
Treatment
Treatment of FGR is multidisciplinary and depends on the severity of the condition. It may include:
- General treatment: providing adequate nutrition to the mother, monitoring the condition of the fetus, using vitamins and minerals.
- Pharmacological treatment: prescribing medications to correct concomitant diseases such as hypertension or diabetes, as well as drugs that improve blood circulation.
- Surgical treatment: In rare cases, surgery may be required in cases of congenital abnormalities of the fetus.
- Other treatments: regular monitoring of the fetus, possible physiotherapy sessions for the mother.
List of medications used to treat this disease
Medicines used to treat FGR may include:
- Folic acid.
- Iron-containing drugs.
- Low dose aspirin (in case of risk of blood clots).
- Antihypertensive drugs.
- Antibiotics if there are infections.
Disease monitoring
Monitoring and control of the fetus are important aspects of the treatment of IUGR. The main stages of monitoring include:
- Regular ultrasound examinations to assess fetal growth.
- Laboratory tests (blood tests) to monitor the condition of the mother and fetus.
- Evaluation of clinical signs, which allows for timely detection of possible complications.
- Prognosis: With timely diagnosis and adequate treatment, the prognosis can be favorable.
- Complications: decreased quality of life, possible health problems in later life, such as delayed psychomotor development.
Age-related features of the disease
Intrauterine growth retardation may have different manifestations depending on age groups. Newborns suffering from intrauterine growth retardation may have an increased risk of diseases such as pulmonary insufficiency syndrome and cardiovascular pathologies. Older children also experience delays in psychomotor development and learning activity. Adolescents may have problem areas in social adaptation and physical development.
Questions and Answers
- What are the main causes of intrauterine growth retardation? The main causes include genetic changes, chronic diseases in the mother, nutritional deficiencies and exposure to toxic factors.
- How is intrauterine growth retardation diagnosed? Diagnosis includes assessment of fetal size using ultrasound, laboratory tests and clinical assessment of the mother's condition.
- What are the consequences of intrauterine growth retardation? Possible consequences include complications during childbirth, a high risk of premature birth, and the development of chronic diseases in the newborn.
- What is the role of genetic factors in the development of FGR? Genetic factors can significantly influence fetal development, including the presence of certain mutations and chromosomal abnormalities.
- How can intrauterine growth retardation be prevented? Preventive measures include early prenatal care, proper nutrition, and monitoring of the mother's health throughout pregnancy.
Dr. Oleg Korzhikov offers some advice for expectant mothers to reduce the risk of intrauterine growth retardation. First of all, it is important to monitor your health and visit your doctor regularly. Include more fresh fruits, vegetables, and protein products in your diet to ensure nutrition for both you and your fetus. If you have chronic diseases, be sure to consult with your doctor and follow all instructions. Also remember the importance of avoiding alcohol and smoking, as these factors can significantly affect the development of the child.
