P54.1: Neonatal melaena

The gastrointestinal area can be divided into upper and lower areas. The upper part includes the esophagus, the stomach and the first section of the small intestine. The lower part includes the rest of the small intestine plus the large intestine. The inside of the esophagus, stomach and intestines is lined with mucous membrane. A mucous membrane is a moist skin.

A newborn baby's first stool is dark or black. This is normal. This first stool is called the meconium. If there is bleeding in the gastrointestinal area, the stool following the meconium may be black.

There may be bleeding in the gastrointestinal area if the mucous membrane is irritated or inflamed, for example. There may also be bleeding in the gastrointestinal area if the liver is damaged. If there is a disorder in the blood clotting system, the bleed may be heavier or longer than usual.
