Preterm birth, also known as premature birth, is the birth of a baby at fewer than 37 weeks gestational age, as opposed to full-term delivery at approximately 40 weeks. [1] Extreme preterm [ 2 ] is less than 28 weeks, very early preterm birth is between 28 and 32 weeks, early preterm birth occurs between 32 and 34 weeks, late preterm birth is ...

[1] [2] [3] Macrosomia is a similar term that describes excessive birth weight, but refers to an absolute measurement, regardless of gestational age. [4] Typically the threshold for diagnosing macrosomia is a body weight between 4,000 and 4,500 grams (8 lb 13 oz and 9 lb 15 oz), or more, measured at birth, but there are difficulties reaching a ...
A preterm birth, also known as premature birth, is defined as babies born alive before 37 weeks of pregnancy are completed. [40] There are three types of preterm births: extremely preterm (less than 28 weeks), very preterm (28 to 32 weeks) and moderate to late preterm (32 to 37 weeks). [40]
Final weight gain takes place during the third trimester; this is the most weight gain throughout the pregnancy. The woman's abdomen will transform in shape as the fetus turns in a downward position ready for birth. The woman's navel will sometimes become convex, "popping" out, due to the expanding abdomen. The uterus, the muscular organ that ...
At the visits, OB/GYNs check maternal nutrition and weight gain because they are linked to the baby's weight gain. The mother having a healthy diet is essential for the baby. Maintaining good nutrition by taking folic acid, which can be found in fruits and vegetables, is linked to the prevention of [61] [62] premature births and low birth weight.
Late preterm infants are infants born at a gestational age between 34 + 0 ⁄ 7 weeks and 36 + 6 ⁄ 7 weeks. [1] They have higher morbidity and mortality rates than term infants (gestational age ≥37 weeks) due to their relative physiologic and metabolic immaturity, even though they are often the size and weight of some term infants.
This complication can cause nutritional deficiency, low pregnancy weight gain, dehydration, and vitamin, electrolyte, and acid-based disturbances in the mother. It has been shown to cause low birth weight, small gestational age, preterm birth, and poor APGAR scores in the infant.
