Introduction

This page is an introduction to postnatal gastrointestinal tract development. This nutritionally involves a change from prenatal placental vascular nutrition to postnatal oral colostrum/milk enteral nutrition (enteral = nutritient delivery as fluid into the gastrointestinal tract).


These notes should be read in conjunction with the detailed page Milk Notes and an understanding of prenatal Gastrointestinal Tract Development.

Some Recent Findings

Lipid Signalling

Lipids present in the intestine leads to a reduction in nutrient intake. Recent research has shown that lipids present in the intestine can also regulate endogenous nutrient production.[2]

Signalling pathway:

presence of ingested lipids

intestinal lipid sensors

signal to the brain

liver

reduction in endogenous glucose production
