What is a premature baby?
A premature baby is born too early. A full pregnancy lasts 37 to 40 weeks, so a premature baby is born anytime before the 37th week of pregnancy.
The more premature babies are, the more likely they are to have complications at birth and later. Babies born before 23 weeks probably won't live.
Because premature babies had less time to grow in the womb, their organs are not fully developed
Premature babies may have trouble breathing and feeding and are more likely to get infections
Many premature babies have no long-term problems
Very premature babies have a higher chance of long-term health problems such as cerebral palsy Cerebral Palsy Cerebrum (cerebral) is a medical word for the large part of the brain that controls muscles.

What causes a baby to be born prematurely?
Most of the time, there's no clear reason why a baby is born too early.
The chances of having a premature baby are higher if the mother:
Had a previous premature baby
Has had multiple miscarriages or abortions
Has other health problems, such as preeclampsia Preeclampsia and Eclampsia Preeclampsia is a certain type of high blood pressure that happens during pregnancy.

What are symptoms of a premature baby?
Premature babies look a little different than full-term babies. They usually:
Weigh between 1 and 5.5 pounds (500 to 2500 grams)
Have a head that looks large compared to the rest of their body
Lack fat under their skin
Have thin, shiny, pink skin
Have veins visible through their skin
Premature babies often:
Breathe quickly and may pause for seconds at a time (apnea)
Have trouble regulating their body temperature
Have trouble sucking and swallowing
What complications do premature babies have?
Premature babies get complications because their organs aren't fully developed. The more premature they are, the more complications they get.
Brain complications: Weak breathing, trouble sucking and swallowing, brain bleeding Bleeding in and around the brain Birth injury is damage that occurs as a result of physical pressure during the birthing process, usually during transit through the birth canal.

Immune system complications: Infections in their bloodstream (sepsis) or around their brain (meningitis)
Lung complications: Lungs clogged with fluid (respiratory distress syndrome)
Eye complications: Bleeding and scarring in the retina (the seeing part of the eyes), a problem called retinopathy of prematurity
Most complications go away after a while. But babies who had severe complications may keep having problems with their breathing or vision.
How do doctors treat premature babies?
Doctors will care for your baby in the hospital in a special unit for sick newborns. It's called a NICU, which stands for neonatal intensive care unit. They'll also:
Put your baby in an incubator to help keep the baby warm
Give medicine into your baby's lungs to help your baby breathe, and sometimes put a tube in the baby's nose or mouth attached to a breathing machine (ventilator)
Feed your baby through a vein or feeding tube until your baby can suck and swallow
Put the baby under special UV lights to treat jaundice
