Understanding the Causes of Fetal Abnormalities
Fetal abnormalities can mainly arise from two types of genetic issues. The first one is related to genetic defects inherited from parents, which is most common among individuals with familial hereditary diseases or in cases of consanguineous marriages. The second cause stems from non-genetic factors, often resulting from maternal neglect of teratogenic risks during pregnancy. This article explores seven types of pregnant women who may be more susceptible to these non-genetic risks.
1. Women Who Experience Viral Infections in Early Pregnancy
Pregnant women who contract viral infections during the early stages of pregnancy may face an increased risk of fetal abnormalities. The timing and type of the infection can significantly affect fetal development, making awareness crucial for expectant mothers.
2. Exposure to Toxic Substances or Radiation
Pregnant women who have been in contact with toxic materials or have been exposed to radiation are at a higher risk of giving birth to babies with abnormalities. It is essential for these women to minimize exposure to hazardous environments during their pregnancy.
3. Use of Harmful Medications
All medications come with potential side effects, making it imperative for pregnant women to adhere to the principle of minimizing drug use. If medication is necessary, consulting a healthcare professional to understand the risks and benefits is essential.
4. Pregnant Women with Cats
Owning a pet cat poses risks, as cats can be carriers of toxoplasmosis, a parasitic infection. If a pregnant woman contracts this infection, it may lead to severe consequences such as congenital blindness or hydrocephalus in the newborn.
5. Frequent Use of Heavy Makeup
Women who regularly apply heavy cosmetics may be unknowingly exposing themselves and their unborn babies to toxic substances like lead and mercury. These harmful chemicals can be absorbed through the skin and cross the placental barrier, potentially affecting fetal development.
6. Pregnant Women with Frequent Negative Emotions
Constant emotional distress can influence hormone levels, particularly adrenal cortical hormones, which can interfere with the normal fusion of embryonic tissues. This disruption may lead to conditions such as cleft lip or palate.
7. Women Who Take Hot Baths in Early Pregnancy
Some expectant mothers indulge in hot baths or steam baths during the first trimester. However, high temperatures and humid environments can adversely impact the development of the fetal brain and spinal cord.
Importance of Prenatal Diagnosis
All pregnant women who fall into the above categories should consider undergoing prenatal diagnostics. If any abnormalities or hereditary conditions are detected, early intervention, such as selective termination, may be recommended to ensure better outcomes for maternal and fetal health.
