Squatting has been the natural position for humans to poop since time immemorial. In this post I look at some of the benefits of squatting and why its better than sitting down for a poo.
There is a brain in your bowel!
Did you know that the gut is the only organ that contains an intrinsic nervous system that is able to mediate reflexes in complete absence of input from the brain or spinal cord? It’s called our enteric nervous system. The enteric nervous system allows the gut to function on its own most of the time. It’s like having a brain in your bowel!
Every class of neurotransmitter found in the brain is present in the enteric nervous system. Neurotransmitters are the words cells use for communicating with one another and with the cells under their control. The multiplicity of neurotransmitters in the bowel suggests that the language spoken by the cells of the enteric nervous system is as rich and complex as that of the brain.
There is a communication line between the brain and the enteric nervous system called the gut-brain axis. Messages are continually being sent from the gut to the brain and from the brain to the gut. Problems with the smooth flow of information up and down this communication line is thought to play a role in IBS.
Studies suggest that the perception of gut stimuli via the gut-brain axis can be modulated by psychological treatments such as gut directed hypnotherapy and cognitive behavioural therapy.
During a gut directed hypnotherapy program suggestions and metaphors are used with the aim of resolving any issues with the gut-brain axis so that full and proper communication is restored. For example, I might suggest to a client that they are in the operations room in their gut, standing in front of a switchboard, like they used to use to manually connect phone calls. Some of the cables have fallen out of the sockets in the switchboard and need to be reinserted. I’ll ask the client to imagine they are putting all the cables back in their correct locations on the board and then have them test that all is working by making a test call. I’ll also get them to check that all the lights on the switchboard are green signifying communication has been fully restored.
This is just one of a variety of metaphors I use with my IBS clients. The wonderful thing about metaphors is that they are the language of the non-conscious mind which processes using images and symbols. So with the help of metaphors, we can communicate with the head brain and the gut brain.
Why understanding your gut and IBS is important
The Gut Brain and its role in IBS
The field of neuroscience has discovered that in addition to our head (cephalic) brain, we have complex and functional brains in both our heart and gut. Called the cardiac and enteric brains respectively, scientific evidence is emerging that these neural networks exhibit intelligence and wisdom.
These three brains are all part of one nervous system and are in constant communication, and interact, with each other for our optimal functioning. We also have complex neural networks that communicate with these three brains.
The gut- heart – head -communication cycle
Research suggests that IBS could be the manifestation of a problem within our gut- heart - head - communication cycle. Poorly coordinated signals between the head brain and the gut brain can cause our body to overreact to changes that normally occur in the digestive process, resulting in pain, diarrhoea or constipation.
Do we really have 3 brains?
What constitutes a brain?
Large numbers of neurons and ganglia, including sensory neurons and motor neurons
Neural cells with inter-neurons; neurons interconnecting with other neurons
Support cells and components such as glial cells, astrocytes, proteins, etc.
Functional attributes: perceiving/assimilating information, processing information, memory storage and access
Able to mediate complex reflexes via an intrinsic nervous system (i.e. it doesn't need the head brain to direct it, it functions even in the complete absence of the head brain)
A chemical warehouse of neurotransmitters (those found in the head brain are also found in the gut and heart brains)

Each of our three brains has a particular role
Each brain has a particular role.
The head – our intellectual brain - thinking, problem solving, creative, rational, logical. We ‘think things through’ and ‘use our head.’
The heart – our emotional brain. We ‘follow our heart’s desires’. We are ‘true to our heart.’ We know when our ‘heart’s not in it,’ or that we have ‘a broken heart.’
The gut – our intuitive/instinctive brain. We ‘follow our gut’ and rely on our ‘gut instincts’. We ‘trust our gut.’ Often we are unable to ‘swallow’ or ‘digest the facts.’ We get ‘butterflies in the stomach.’
Let’s take a closer look at the Gut Brain
The gut (enteric) brain was discovered just over 100 years ago, but is ancient in evolutionary terms and predates the head brain and central nervous system.
Back when evolution was at the stage of complexity of sea cucumbers and worms, organisms only had a neural processing system of an enteric brain. This intelligence was used to detect threats and food in the environment and move away from danger and towards food.
The human gut brain contains over 500 million neurons located in the sheaths of tissue lining the oesophagus, stomach, small and large intestines, colon and bowel. It has the equivalent size and complexity of something like a cat's brain. It sends and receives nerve signals throughout the chest and torso and innervates organs as diverse as the pancreas, lungs, diaphragm and liver.
Of the 500 million neurons in the gut, more than 100 million are located in the small intestine, roughly the same number as in our spinal cord. Once you add in the nerve cells in the oesophagus, stomach and large intestine and the total number of nerve cells exceeds those in the spinal cord.
The enteric nervous system is also a vast chemical factory within which is found every one of the classes of neurotransmitter found in the head brain. Neurotransmitters are the signals brain cells use to communicate with each other and with the cells under their control. Major neurotransmitters found in the enteric brain include serotonin, dopamine, glutamate, norepinehrine and nitric oxide. Interestingly, over 95 percent of the serotonin used throughout the body and brain is made in the gut. Brain peptides and endorphins have also been found in the gut.
Research has shown that more than 80 percent of our immune cells are located in the gut, and the gut brain is intimately involved in managing immune function. Some people with IBS have an increased number of immune-system cells in their intestines. This immune-system response is associated with pain and diarrhea.
The gut is also a large source of benzodiazepines, which are psychoactive chemicals used in popular drugs such as Valium and Xanax. It's been found that in times of massive acute stress, the gut produces sufficient benzodiazepines to calm and sedate the head brain, downregulating the cognitive and emotional stress response. Our gut literally hijacks the head brain. This is why when in danger we are limited to ‘black and white’/’all or nothing’ thinking and, can 'choke' with emotion.
The gut brain can learn!
There is evidence that the gut brain exhibits plasticity and can learn, form memories, take on new behaviours and grow new neurons, just like our head brain can.
Research performed by gastroenterologist Dr Yuri Saito Loftus from the Mayo Clinic, indicates that the gut brain learns from traumatic experiences such as the death of a loved one, divorce, natural disasters, accidents and physical or mental abuse. These traumatic experiences can cause changes in the nerves and muscles that control sensation and motility of the bowel.
Dr. Jackie D Wood, a professor at Ohio State University, and leading expert on the enteric nervous system (ENS) who named the ENS ‘The brain-in-the-gut,’ says there’s a growing body of evidence that suggests that autoimmune diseases like Crohn's disease and ulcerative colitis may involve the gut brain.
Gut Directed Hypnotherapy
The focus of gut directed hypnotherapy is communicating with all three brains that control our mind body system. A key element of the Hypno4IBS programme is to identify and systematically de-traumatise past trauma, effectively changing the way the traumatic memories are encoded in the brain(s) and to positively affect the workings of the ENS.
