Top 8 Causes of SIBO

Table of Contents

SIBO, or Small Intestinal Bacterial Overgrowth, as the abbreviation is also known, is a condition that plagues the population of millions in the world, though the phenomenon has not been commonly known. The causes of SIBO may be what is causing your problem, in case you are experiencing unexplainable stomach issues, bloating, or stomach pain.

SIBO is a condition that develops when the bacteria that would otherwise be present in the large intestine migrate and grow in the small intestine. This kind of imbalance in bacteria will lead to uncomfortable symptoms and serious conditions of health conditions if not treating the imbalance.

Educating yourself on the causes of SIBO will help you to be aware of potential triggers and to cooperate with medical workers in order to develop effective therapy plans. Such as in the case of Conscious Medicine, integrative medicine is functional in that the causes are treated rather than the symptoms.

What is SIBO?

SIBO is an abbreviation that means Small Intestinal Bacterial Overgrowth. When simplified, it means that you have excess bacteria in your small intestine that do not belong there.

Most bacteria are kept in your large intestine in the normal course of activities by your digestive system. There should also be a relatively small number of bacteria in the small intestine since it is where most of the nutrients that you intake with food are absorbed by your body.

Bacteria cause problems with the digestion process and nutrient absorption when they overgrow in the small intestine. The food you consume is fermented by these bacteria and results in gases, which lead to bloating, pain, and other unpleasant disorders.

SIBO presents with such symptoms as chronic bloating, abdominal pain, diarrhea, constipation, excess gas, and deficiencies in nutrients. Fatigue, brain fog, and food sensitivities are also common in many patients with SIBO.

What is the Root Causes of SIBO?

The underlying causes of SIBO is connected with the impairments of the normal processes of your body that help to provide bacteria with their correct locations. There are many protective mechanisms that are built into your digestive system so that the bacteria cannot overgrow.

Through these protective mechanisms, the bacteria may escape the large intestine into the small intestine and multiply at a high rate in case they fail. Knowing what these natural defenses are disrupted will be used to determine the particular triggers of SIBO in an individual.

SIBO is largely a combination of factors as opposed to one factor. This is the reason why the methods of functional medicine, when all the underlying factors are addressed, are more likely to be successful, as compared to treatments that target only one of the factors.

8 Main Causes of SIBO

8 Main Causes of SIBO

Knowing the main causes of SIBO can help you recognize which of the factors can be the reasons for your condition. Each of these causes influences your digestive system in a different way, yet all the causes may cause bacterial overgrowth.

1. Low Stomach Acid

One of the most widespread causes of SIBO is low stomach acid. To destroy the bacteria and other bad microorganisms in food, your stomach secretes acid.

In a case when there is a low level of stomach acid, the bacteria may make it to your small intestine in their live form. These surviving bacteria, in turn, increase and cause overgrowth.

Some causes that inhibit the production of stomach acids involve aging, chronic stress, some medications and autoimmune diseases. Heartburn drugs that inhibit proton pumps are also a cause of concern since they significantly decrease the production of acid.

2. Motor Complex Dysfunction Migration.

This is because the Migrating Motor Complex is the natural cleaning of your intestine. It produces the effect of waves that scrub your small intestine openings up into your large intestine and cleans the gunk out of your body.

This cleaning process occurs as the digestive system is at rest, usually between meals. In cases where the MMC fails to do the right job, the bacteria may be left in the small intestine and proliferate.

Some of the conditions that interfere with the functionality of MMC are regular snacking, some drugs, diabetes, hypothyroidism, and chronic stress. Nerves that control MMC functions may also be destroyed as a result of food poisoning.

3. Intestinal Nerve and Muscle Dysfunction.

The intestines depend on very sophisticated nerve and muscle coordination that helps the food and bacteria to traverse your digestive tract in the right way. In case of malfunction of these systems, the usual intestinal motility decelerates.

The low motility rate gives bacteria increased time to multiply within the small intestine before they are moved into the large intestine. This forms the perfect environment for the development of SIBO.

Diabetes and autoimmune diseases, together with infections or specific medications, may cause nerve damage. The dysfunction of the muscles can be a result of connective tissue disorders, thyroid issues, or chronic inflammation.

4. Disturbed Bile Secretion and Pancreatic Enzyme Release.

Bile and digestive enzymes assist in the breakdown of food, and they possess natural antibacterial effects. Bacteria can overgrow easily when there is a hindrance in the production or flow of these substances.

Your liver produces the bile, which is stored in your gallbladder. It aids in the digestion of fats and also acts as an antimicrobial properties which aids in the control of the bacteria in your intestines.

Such disorders as bile flow are gallbladder disease, liver issues, and pancreatic insufficiency. Inadequate bile flow is frequently disregarded as one of the causes of SIBO, but it may be extremely important.

5. Stress

Chronic stress has a great effect on your digestive system, and it is one of the significant causes of SIBO that should not be overlooked by many people. There are various ways that stress influences digestion.

Stress inhibits the production of stomach acid, decreases the motility of the intestine, and compromises immunity. All this predisposes to bacterial proliferation in the small intestine.

The gut-brain relationship is that emotional and psychological stress has a direct impact on your digestive system. The balance of bacteria in all the parts of your intestines may be disrupted by chronic stress.

6. Food Poisoning

The development of SIBO can be aggravated by food poisoning, which leads to the development of post-infectious IBS. The infection destroys nerve cells of the intestines and changes the pattern of normal motility.

The digestive damage may last months or even years, even after the original infection has cleared. This provides continued favorable conditions for bacterial overgrowth.

The bacteria that can cause SIBO, as common causes of food poisoning are Campylobacter, Salmonella, Shigella, and E. coli. A large number of individuals having SIBO have the ability to pinpoint their symptoms to a certain food poisoning episode.

7. Slow Bowel Transit

Constipation is also referred to as slow bowel movement, which gives bacteria additional time to multiply in the small intestine before being expelled. This is among the mechanical causes of SIBO.

The usual bowel passage is 12 to 48 hours after eating to expelling. Bacteria get more time to proliferate in the wrong location when there is a longer transit time.

Slow bowel transit is caused by dehydration, low fiber consumption, physical inactivity, some drugs and many diseases such as hypothyroidism.

8. Medications

A variety of drugs may also lead to the development of SIBO, interfering with the natural defenses of the body against bacterial invasion.

Proton pump inhibitors lower the amount of stomach acid, and bacteria are able to pass through the stomach. Antibiotics may cause an imbalance in the natural bacteria of the entire digestive tract.

Opioid analgesics reduce bowel movements, which provides bacteria with additional time to multiply. Other drugs with possible contribution include antidepressants like tricyclic antidepressants, alcohol, some blood pressure medications, as well as antispasmodics.

How is SIBO Diagnosed?

How is SIBO Diagnosed

The diagnosis of SIBO is usually done through the method of breath testing, where the concentration of gases that are produced by bacteria in your small intestines is measured. The most widespread tests involve the use of lactulose or glucose as a substrate.

In the test, you also take a sugar solution and breath into collection tubes at specific times. The presence of high levels of hydrogen or methane means that your small intestine is overgrown by bacteria.

Diagnosis is also dependent on symptom assessment and medical history. You will be asked by your healthcare provider regarding digestive symptoms, medical history, and possible risk factors.

What Is The Fastest Way To Cure Sibo?

The most effective treatment of SIBO is focused on the elimination of both bacterial overgrowth and the factors that have led to the appearance of such a situation. Several methods are normally used in treatment.

The bacterial overgrowth may be minimized by antimicrobial therapy based on antibiotics or herbal antimicrobials. Nevertheless, this method is not sufficient to prevent recurrence unless some underlying causes are addressed.

Such functional medicine methods as those employed at Conscious Medicine include the identification and treatment of underlying causes of SIBO. Such an holistic strategy can tend to give more sustainable outcomes.

Therapy might involve diet therapy, digestive aid formulations, stress therapy and underlying disorders such as low stomach acid or gastrointestinal motility issues.

What Can I Do to Avoid SIBO Recurrence?

To avert the recurrence of SIBO, it is necessary to continue paying attention to the factors that stimulated its development in the first place. It is not applicable to merely treat the bacterial overgrowth and be successful in the long term.

Treat underlying disorders such as stomach acid deficiency, lack of motility or chronic stress. All these root causes should be rectified in order to ensure that bacteria do not grow again.

Eat well and leave some space in between the meals to ensure that your MMC works well. Snacking should be avoided and should not interfere with this natural cleaning process.

Promote digestive health with the aid of proper supplements, stress, and exercise. These are the lifestyle factors that contribute to the normal bacterial balance.

Conclusion

To treat and prevent SIBO, it is necessary to know its causes. There are eight primary causes, namely low stomach acid, MMC dysfunction, nerve and muscle problems, altered bile flow, stress, food poisoning, slow transit and medications.

SIBO is not often caused by one factor only, and that is why complex methods covering a variety of factors are the most likely to be successful. Physicians of functional medicine, including Conscious Medicine, focus on root cause identification and treatment.

In case you think that you have SIBO, collaborate with medical workers who are aware of these underlying causes and can create their own treatment regimes. The most effective opportunity of achieving permanent relief is to treat root causes as opposed to just symptoms.

The trick to success is to realize that SIBO is not always an illness, but a manifestation of some underlying digestive dysfunction. With a solution to these deeper problems, you will be able to resume normal digestive activity and long-term digestive health.
