Question

Quizplus · Accepted Answer

Malnutrition and tobacco are major teratogens during the fetal period. Malnutrition can lead to stunted growth, developmental delays, and birth defects. Tobacco use during pregnancy has been linked to low birth weight, premature birth, and other health problems for the baby. Lack of maternal sleep, lack of exercise, excessive maternal weight gain, maternal age, sugar, and starch are not considered major teratogens during the fetal period, although they can still have an impact on maternal and fetal health.
