Posted on 4:03 AM | By shafiq | In What causes having a small baby and will the baby
My sister's daughter was small due to the fact she smoked throughout her pregnancy (stupid right?) Anyway, there are many factors that can contribute to a low-birthweight baby. Here are some causes:
Birth defects: Babies with certain birth defects are more likely to be small for date because genetic conditions or environmental factors may limit normal development (3, 4).
Chronic health problems in the mother: Maternal high blood pressure, diabetes, heart, lung and kidney problems sometimes can reduce birthweight (3).
Smoking: Pregnant women who smoke cigarettes are nearly twice as likely to have a low-birthweight baby as women who do not smoke (5). Smoking slows fetal growth and increases the risk of premature delivery (5).
Infections in the mother: Certain infections, especially those involving the genito-urinary tract, may increase the risk of preterm delivery (2).
Infections in the fetus: Infection with certain viruses, including cytomegalovirus, rubella and chickenpox, can slow fetal growth and cause birth defects (3, 4).
Alcohol and illicit drugs: Alcohol and illicit drugs can limit fetal growth and can cause birth defects (3, 4). Some drugs, such as cocaine, also may increase the risk of premature delivery.
Placental problems: Placental problems can reduce flow of blood and nutrients to the fetus, limiting growth. In some cases, a baby may need to be delivered early to prevent serious complications in mother and baby.
Inadequate maternal weight gain: Women who gain too few pounds during pregnancy increase their risk of having a low-birthweight baby (3). Women of normal weight should usually gain 25 to 35 pounds during pregnancy.
