The Mesentery

New Organ Classification, Longstanding Importance

Angela Power


Breaking news at the beginning of this year announcing the ‘discovery of a new organ’, the Mesentery. This discovery is in-fact a new classification of some of the membranes within the abdomen. In recent years more information about the importance of these membranes has been recognised.

As a visceral osteopath, I have known about the importance of the Mesentery and been treating it for the last ten years. Classifying it as an organ makes it easier for me to describe it and, for anyone interested before or after treatment, information is more readily available.

The Mesentery sits within the abdomen and takes up a large proportion of it. It attaches onto the back abdominal wall, in front of the L4 and L5 vertebrae and over the Sacrum. It supports the small intestines and colon, providing blood and nerve stimulation, and taking away newly digested nutrients. It also offers an environment for our Biome (see below) to interact with our body.


The Biome is the friendly bacteria that inhabits our gut, contributing to the break-down of foods. It releases chemicals into our blood stream that modulate our hormone and immune systems. The Mesentery monitors and enables communication between the Biome, our digestion and the rest of our bodies.


The Mesentery is a large organ filling most of the abdominal space, with connections onto the spine. It has implications whenever there is spinal stiffness or dysfunction and responds well to visceral treatment. Releasing tension in the Mesentery can affect dysfunction in the gut, core muscles and spine.
