Alcohol and smoking are among the most well-known factors that negatively affect the health of the unborn child. They are especially dangerous for women planning to become pregnant, as they can increase the risk of neural tube defects. The neural tube forms in the first 3–4 weeks of pregnancy, even before many women know they are pregnant, so any harmful habits that exist before conception can affect foetal development.
Alcohol is quickly absorbed into a woman’s body and enters the bloodstream, affecting cells and tissues. Even small doses can disrupt the normal development of the neural tube in the foetus, increasing the risk of spina bifida, anencephaly and other congenital defects. Chronic or regular alcohol consumption increases this risk and can lead to more serious health consequences for the child.
Smoking also has a direct negative impact on foetal development. Nicotine and other harmful substances in cigarettes reduce the supply of oxygen and nutrients to the baby, disrupt metabolism and increase the level of toxins in the mother’s body. These processes can interfere with the proper closure of the neural tube and increase the likelihood of congenital disorders. In addition, smoking can exacerbate the effects of other risk factors, such as folate deficiency or chronic diseases.
Prevention of these risks begins long before pregnancy. Women are advised to completely give up alcohol and smoking even at the stage of planning a child. Giving up bad habits improves health, normalises metabolism and increases the chances of healthy foetal development. It also has a positive effect on overall well-being and reduces the risk of complications during pregnancy.
It is important to remember that the prevention of congenital neural tube defects requires a comprehensive approach. In addition to giving up alcohol and smoking, it is necessary to take folic acid, eat a healthy diet, control chronic diseases, and undergo regular medical examinations. All these measures together create safe conditions for the development of the child from the very first weeks of life.
Avoiding alcohol and smoking is one of the simplest but most effective steps an expectant mother can take to reduce the risk of neural tube defects. A healthy lifestyle before pregnancy not only helps prevent congenital disorders, but also ensures better well-being for the mother and harmonious development of the child.
