A teratogen is a substance or agent that can cause physical or mental deformities in an unborn baby. In 2023, the list of teratogens and their effects is an important topic for expecting mothers and their families. It is essential to be aware of the possible risks associated with certain substances and agents during pregnancy. This article intends to provide a comprehensive overview of the known teratogens and their effects.
1. Alcohol
The Centers for Disease Control and Prevention (CDC) states that there is no safe level of alcohol consumption during pregnancy. Alcohol consumption in pregnancy can lead to a range of physical and mental birth defects, known as Fetal Alcohol Spectrum Disorders (FASDs). Physical defects can include craniofacial deformities, heart defects, and joint and limb malformations. Intellectual disabilities, behavioral challenges, and difficulty with learning and memory can be some of the mental effects.
2. Tobacco
Women who smoke during pregnancy are at an increased risk of miscarrying or having a baby with a low birth weight. Babies born to women who smoke are also more likely to suffer from respiratory illnesses, congenital heart defects, and cleft palate. Additionally, the use of nicotine and other chemicals in cigarettes can lead to a higher risk of Sudden Infant Death Syndrome (SIDS).
3. Drugs
Illegal drug use during pregnancy can have serious effects on an unborn baby. Cocaine and heroin can cause birth defects, low birth weight, and withdrawal symptoms in infants. The use of prescription drugs such as benzodiazepines, anticonvulsants, and antithyroid drugs can also have adverse effects.
4. Radiation
Maternal exposure to radiation can cause a range of birth defects. Radiation can also increase the risk of miscarriage, or stillbirth in severe cases. Exposure to radiation during pregnancy can also lead to an increased risk of childhood cancer, cognitive impairment, and learning disabilities in the baby.
5. Pesticides
Pesticides are chemicals used to kill insects and other pests. Pesticides can be absorbed through the skin, or ingested by eating or drinking contaminated food or water. Exposure to pesticides during pregnancy can cause birth defects, miscarriage, and stillbirth. It can also lead to developmental delays and behavioral problems in the baby.
6. Heavy Metals
Exposure to heavy metals such as lead, mercury, and arsenic during pregnancy can have serious effects on an unborn baby. Heavy metal exposure can cause developmental delays, learning disabilities, and physical abnormalities. It can also lead to an increased risk of miscarriage, stillbirth, and childhood cancer.
7. Infectious Diseases
Infectious diseases can be passed from the mother to the unborn baby through the placenta. Toxoplasmosis, cytomegalovirus, rubella, and syphilis can all cause birth defects in the baby. Infections such as HIV and hepatitis can also cause serious health problems in the baby.
8. Medications
Some medications can be harmful to an unborn baby. Common medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), anti-seizure drugs, and antibiotics can cause birth defects, and other problems in the baby. It is important to check with a doctor before taking any medication during pregnancy.
9. Environmental Agents
Environmental agents such as air and water pollutants can also cause birth defects. Pollutants such as lead, mercury, and arsenic can be found in contaminated air and water. Exposure to these pollutants during pregnancy can cause physical and mental birth defects, and an increased risk of miscarriage and stillbirth.
10. Stress
High levels of stress during pregnancy can have an adverse effect on the development of the baby. Stress can cause physical and mental birth defects, as well as an increased risk of miscarriage, preterm labor, and low birth weight. It is important for pregnant women to seek support if they are feeling stressed or anxious.
