To find the right irritable bowel syndrome treatment it is a good idea to understand ibs symptoms and what is the cause of irritable bowel syndrome in the first place.

Irritable bowel syndrome is believed to come about when the muscles of the organs of the gastrointestinal tract or the nerves controlling the organs function abnormally. The nerve control system of the gastrointestinal tract is quite complex.   The system runs all the way from the gastrointestinal tract from the aesophagus to the anus in the muscle walls of the organs.

These nerves “talk to” other nerves which go backwards and forwards from the spinal cord. Nerves within the spinal cord, in turn, travel to and from the brain. (Only the spinal cord and brain contain more nerves than the gastrointestinal tract). Therefore if there is an abnormal nervous function in IBS, it may originate in a gastrointestinal muscular organ, the spinal cord, or the brain.

And-just as with most other bodily organs-there are found both sensory and motor nerves within the gastrointestinal organs.  The sensory nerves SENSE what’s going on and RELAY the information to the nerves found  in the organ’s wall.  This information is then sent to the spinal cord and brain. The information is received and processed in the organ’s wall, the spinal cord, or the brain. Based on how the input is processed,  commands  or “responses” are transmitted to the organ over the motor nerves. Two common ways the intestine responds is to contract or relax  the organ muscle and secrete fluid and/or mucus into the organ.

As stated, if the nerves in the organs in the area in question behave abnormally, it might happen in either the organ, spinal cord, or brain. Also, the abnormalities might occur in the sensory nerves, the motor nerves, or at processing centres in the spinal cord, intestine or  the brain. It has been mooted in some studies that the cause of functional diseases is abnormalities is dysfunction of the sensory nerves. For example, a normal event such as the food causing the small intestine to distend might cause abnormal sensory signals to be sent to the spinal cord and brain, where they end up as pain sensations.

With regards to  irritable bowel syndrome treatment,some studies seem to suggest that the cause of ibs is the abnormal function of the motor nerves. For example, if the motor nerves receive an abnormal command, this may result in a  painful spasm or contraction of the muscles. Still others argue that abnormally functioning processing centers are responsible for functional diseases because these end up misinterpreting some normal sensations or send abnormal commands to the organ. In fact, some functional diseases could originate from sensory dysfunction, motor dysfunction, or a combination of both. Still others may be due to abnormalities within the centers that process the information.

When discussing IBS treatment, an area that is getting a lot of scientific attention is GAS cause by bacteria within the intestine of IBS patients.  Studies show that subjects with IBS show unique “ibs symptoms“, one of which is the fact they seem to create a lot more gas than subjects without IBS; and the gas may be retained for a  longer time in the small intestine. Some patients with IBS experience an increase in their abdominal size over the day, reaching a maximum in the evening and returning to normal the next day.  People who do not have IBS do not experience these particular ibs symptoms.

There seems to have been a lot of controversy over the assertion that  poor digestion and/or absorption of dietary sugars can exacerbate the IBS symptoms. Unabsorbed sugars also cause more gas. Lactose, or milk sugar, if poorly digested and fructose, which is a ubiquitous food sweetener, if poorly absorbed, can both trigger IBS symptoms for this reason.

Although the abnormal production of gas could give rise to some IBS symptoms, there will have to be more work done before the role of intestinal gas in IBS is made moreclear.

Fat in the diet even in healthy individuals causes food as well as gas to move more slowly through the stomach and small intestine. Some patients with IBS may even respond to dietary fat in a pronounced way with greater slowing. Thus, dietary fat could–and probably does–aggravate the symptoms of IBS.
