In a preterm birth a baby is born three weeks before the due date. On an average pregnancy lasts for 40 weeks, however, preterm birth occurs on the 37th week of pregnancy or even earlier. In case of a preterm birth the baby gets less time to develop in the womb. The organs are not fully developed and the baby runs the risk of health problems.
Preterm babies are twice as likely to be left-handed than right-handed. Inheritance and genetic theory offered by research scientists and medical doctors have failed to provide a satisfactory explanation. And this interesting occurrence among preterm babies is under investigation.
- Napoleon Bonaparte, Isaac Newton,Victor Hugo, Mark Twain, Sir Winston Churchill, and Albert Einstein are the most famous preterm babies.
- The smallest preterm baby to survive was born at 21 weeks + 6 days of pregnancy and weighed about 9.1 oz or 258 grams.
- Mothers of preterm babies produce breast milk that is rich in extra fat, protein and minerals as required to nourish the preterm baby. The milk additionally contains antibodies and leukocytes that protects the preterm baby from infection.
Due to recent advances in medical science 90% preterm babies weighing 800 gms survive. And babies weighing around 500 gms show a 50% chance of survival. However, there are greater chance for their full development.
