### **3.6 The uncontrolled ileum - Diarrhoea**

When the ileum is no longer correctly controlled by the primary transport controller, the secondary transport controller moves food soup at speed into the colon. The soup contains high levels of chemicals & possibly fats, and these cause automatic evacuation of the colon. The level of activity in the autonomic nervous system controls the valve at the end of the small intestine. When adrenal hormones are released on arising, the valve is easy to open, and the ileum immediately pushes its contents into the colon (the morning rush). When stress occurs during the day and releases adrenal hormones, the valve is again easier to open. Overnight the valve becomes more firmly closed. In severe cases of IBS-D & A, the ileum can push food soup through the valve at any time.

### **3.6.1 IBS-D caused by a neurotransmitter deficiency**

There are six forms;


#### **3.6.2 IBS-A caused by a neurotransmitter deficiency**

There are two forms;

### **3.8 Other primary control faults**

Any fault that disrupts sensory input from the small intestine to the brain or motor output from the brain to the small intestine will cause IBS symptoms. The section(s) of the intestine that are affected will not be the same as when a neurotransmitter is deficient. The first faulty section will cause an IBS Barrier to form at the start of the following brain controlled section. Subsequent defects will have little effect, except that diarrhoea symptoms will occur when a section that terminates the intestine is faulty. IBS-B cannot be produced by damage to the duodenum walls.

### **4. Variation in the expression of IBS symptoms**

If you compare two subjects with the same type of IBS, the symptoms that they each suffer from can be different. The following factors explain how this variation occurs.

### **4.1 Food variables**

When the enteric nervous system controls movement of food soup in the small intestine, the transport speed varies according to the types of food eaten. Some foods cause very fast speeds and others slower speeds.

More force is used to achieve very fast speeds, and the brain creates a stronger Barrier to stop the flow. A strong Barrier produces a complete transport halt for long periods, and dehydration occurs prematurely. This causes later processes of the small intestine to take longer. **Constipation**, bloating & cramping are increased in severity.

On arising, the valve at the end of the ileum is easy to open, and fast speeds in the ileum trigger the 'morning rush'. Very fast speeds move food into the colon immediately it reaches the end of the ileum.

Cramping occurs when the speed of food is too fast, and a Barrier is formed with its associated bloating. This is the enteric nervous system attempting to force food though the Barrier.

Cramping also occurs when the intestinal muscles are moving food at speed, in any part of the intestine. This cramping is accompanied by loud borborygmi.

When the colon receives food soup from the ileum that contains fat and/or high levels of digestive enzymes, it evacuates at speed, often with cramping.
