During pregnancy, certain activities and habits are strongly discouraged or even forbidden due to potential risks for both the mother and the unborn baby. Here are some things to avoid: Smoking, vaping and alcohol: Smoking and consuming alcohol during pregnancy increase the risk of complications such as premature birth, growth retardation of the baby, congenital abnormalities, and developmental problems. Drug abuse: Using illegal drugs or certain medications not prescribed by a doctor can have serious consequences for the baby's health, including dependence and developmental issues. Raw or Undercooked Foods:: During pregnancy, avoid eating raw meat (such as carpaccio or tartare), raw eggs, and undercooked meats as they may contain bacteria or parasites harmful to the fetus. Your doctor can test whether you are immune to toxoplasmosis, and if so, eating raw vegetables may not be a problem. Too Much Caffeine:: Too much caffeine can increase maternal blood pressure. It is therefore recommended to limit consumption of caffeinated drinks to a maximum of 200 mg per day during pregnancy. Extreme sports: Sports such as skiing, mountaineering, or contact sports are generally discouraged during pregnancy due to the risk of injury for both the mother and the baby. Certain Medications:: Some medications are harmful to the baby's development and should be avoided during pregnancy. It is important to always seek advice from a healthcare provider before taking medications during pregnancy.
