Information for Patients


Premature Babies

Also called: Preemies

Almost 1 of every 10 infants born in the United States are premature, or preemies. A premature birth is when a baby is born before 37 completed weeks of pregnancy. A full-term pregnancy is 40 weeks.

Important growth and development happen throughout pregnancy - especially in the final months and weeks. Because they are born too early, preemies weigh much less than full-term babies. They may have health problems because their organs did not have enough time to develop. Problems that a baby born too early may have include

  • Breathing problems
  • Feeding difficulties
  • Cerebral palsy
  • Developmental delay
  • Vision problems
  • Hearing problems

Preemies need special medical care in a neonatal intensive care unit, or NICU. They stay there until their organ systems can work on their own.

Small Intestine Disorders

Your small intestine is the longest part of your digestive system - about twenty feet long! It connects your stomach to your large intestine (or colon) and folds many times to fit inside your abdomen. Your small intestine does most of the digesting of the foods you eat. It has three areas called the duodenum, the ileum, and the jejunum.

Problems with the small intestine can include:

  • Bleeding
  • Celiac disease
  • Crohn's disease
  • Infections
  • Intestinal cancer
  • Intestinal obstruction
  • Irritable bowel syndrome
  • Ulcers, such as peptic ulcer

Treatment of disorders of the small intestine depends on the cause.
