Irritable Bowel Syndrome can be caused by many different underling factors. What causes symptoms in one person may not be the major problem for another individual. This is why a particular treatment may work well for a certain individual but fail for someone else.


DIGESTIVE INSUFFICIENCY Digestive insufficiency is a deficiency in the substances that help us to break down and utilize the food that we eat. While millions of people take antacids and acid blockers to control their heartburn, little is publicized about the results of having too little stomach acid or a lack of digestive enzymes. If we don’t breakdown our food, we will not have the good nutrition necessary for optimal health. The improperly digested material will go to feed the trillions of organisms that live within our digestive system or it may be absorbed in a way which can initiate food allergies or sensitivities. Some of the common indicators of digestive insufficiency are undigested food in our stool, seeing “streak marks” on the toilet after we defecate or needing to wipe multiple times.

ORGANISM IMBALANCES This is by far the most common cause of intestinal distress in most people!

There are over 100 trillion living organisms which reside within the 30 foot tube of our intestinal tract. In fact, there are TEN TIMES more organisms within our intestines than their are human cells within our ENTIRE BODY! It is estimated that intestinal organisms comprise between 30% to 70% of the weight of our bowel movements.

The life force, or metabolic activity, of these organisms is greater than the metabolic activity of our heart, brain, liver or any other organ in our entire body. The surface area interface between these organisms and our intestinal lining is equivalent to one tennis court in size!

What this all means is that we have a very intimate relationship between what goes on within our digestive system and the health of the rest of our body.

Healthy intestinal organisms help protect the intestinal tract and prevent illness throughout our bodies. The positive effects of healthy intestinal flora include: crowding out the disease causing organisms; producing vitamins, enzymes and natural antibiotics; stimulating the immune system; making amino acids (especially important for vegetarians and vegans); degrading toxins such as drugs and the waste toxins of unhealthy organisms; producing antioxidants and anticancer agents; stimulating our metabolism and feeding the cells that line our digestive system with substances which keep them functioning at an optimal level.

Do you wonder how we got all these critters in us in the first place? At birth, as the child passes through the birth canal, it's mouth wipes against the vaginal wall. The microorganisms which live within the birth canal become the microbial inoculation for the child's entire digestive tract.

The trillions of organisms that live within our intestines need to eat just like we do. They also need to excrete waste products. The difference between health providing organisms and disease causing organisms is that disease causing organisms produce substances which are toxic to our bodies.

It’s all a matter of balance. When our organisms are out of balance, undesirably high amounts of less than optimal organisms take the place of the health providing organisms. These undesirable organisms may contribute to illness both intestinally and all through our body. Undesirable organisms may directly irritate and injure the intestine. They may also produce specific toxins, cause malabsorbtion, inactivate digestive enzymes, convert food into disease causing substances, activate carcinogens, translocate through the intestinal wall into the bloodstream and organs, initiate auto-immune diseases, suppress the immune system, consume our nutrients, produce false vitamins which block the natural vitamins, produce faulty neurotransmitters and accelerate the aging process.

Bacterial overgrowth within the small intestine may be the most common cause of clinically significant malabsorbtion in the elderly. Bacterial imbalances anywhere in the intestinal tract may have negative consequences throughout the entire body.

The detrimental bacteria may form substances which are noxious to the host....These substances may injure the intestine directly and are also partially absorbed, potentially contributing throughout the host's life to aging and geriatric diseases such as cancer, arteriosclerosis, hypertension, liver disorders, autoimmune diseases, and immunosuppression.


It is not uncommon for people with Irritable Bowel Syndrome to have a history of travel where they had an acute intestinal illness such as diarrhea, gastroenteritis or food poisoning. Although their immediate severe symptoms may eventually resolve, for many people, their digestion will never be the same....... to pick up these critters. They are commonly found everywhere throughout the USA.

Two common intestinal parasites:

Entamoeba coli
Giardia lamblia



Some of the organisms that cause intestinal distress can easily be passed from one person to another, especially in "intimate" relationships. The cysts of Giardia lamblia, a common intestinal pathogen, can live under your fingernails for three months and remain capable of transmitting infection, despite hand washing!

Some people recognize that their symptoms of intestinal distress began around the time to a new relationship. Did you know that 1/2 teaspoon of saliva contains 25,000,000,000 (25 billion) microorganisms? Don't overlook your pets. There are numerous types of parasites which have been documented to be transmitted from family pets to humans. For example, H. pylori, the bacteria responsible for causing the vast majority of stomach ulcers, has been found in household cats.


One persons healthy food may be poison for another person. Even food which is regarded as being “good” for us may, in some people, be poorly digested, initiate an allergic irritation of the digestive system or feed undesirable intestinal organisms.

Intestinal damage from food sensitivities may take place even after eating an amount of food that is not large enough to cause an obvious rection. This damage usually results in diminished absorption and/or increased intestinal permeability (leaky gut).
