What are the types?
Most commonly the bowel is blocked but none is missing. In some babies there is a section missing and although usually this is an insignificant amount, in some babies it may be enough to interfere with the baby's ability to absorb milk.
Babies can have over half the bowel missing without there being much effect on milk (or, later, food) absorption. However in some babies there is so much bowel missing that special feeding is needed. This is known as short bowel syndrome. It could mean long term hospitalisation and drip feeding.
