SIBO: How Small Intestinal Bacterial Overgrowth Affects Your Health

by | Oct 18, 2018 | Lupus Blog | 0 comments

Hi. It’s Dr. Connie.


I’ve always had digestive issues from an early age.  Little did I know then what I know now about gut permeability and how we can alter the course of our disease.


Everyday I work proactively to promote a healthy balance of good bacteria in my gut because as soon as I veer off course, my gut tends to get irritated fast.


I am very careful with what I put into my mouth.


I’ve had multiple courses of antibiotics and various medications for Lupus over the last 19 years.


I’ve learned that as long as I can keep my gut in check, all signs and symptoms of Lupus are eliminated.


Most patients that I treat have some degree of digestive issues, but they shrug it off as a normal thing.  I’ve learned that if you don’t know what normal truly is, how can you seek help?


I am obsessed with bowel movements and the symptoms I feel after I eat.


It kinda sucks that my gut feeling largely influences my appetite.


But compared to how I used to feel, which was helpless, tired, and weak, to how I look and feel after adapting this lifestyle which I’ve now embraced for over 10 years, I’d choose the latter any day.


So if you’ve been struggling with brain fog, fatigue, pain, weight gain, bloat after eating, and digestive discomfort, please read on.  You just may have SIBO.


What is SIBO?


SIBO is an acronym for Small Intestinal Bacterial Overgrowth.


Normally, most of our microbiome or gut bacteria (both good and bad) reside in our large intestine.  For those affected with SIBO, we see an overgrowth of bacteria in the small intestine.


The problem with SIBO is that such bacteria react with poorly-digested, fermentable carbohydrates. This produces uncomfortable symptoms such as bloating, gas, abdominal pain, diarrhea and/or constipation.


The effects of SIBO can extend beyond gut symptoms.


As those bacteria continue to thrive where they don’t belong, they excrete acids that can cause neurological symptoms including brain fog and fatigue.


This can eventually lead to leaky gut, causing bacteria and undigested foods to trigger the immune system ultimately leading to various other symptoms and disease.


It also can trigger food sensitivities in certain individuals, creating more complex health problems long term.


Over time, such individuals are at risk for nutrient deficiency because the bacteria begins to impede on one’s ability to absorb much needed nutrients such as B12 and iron.


Such deficiencies commonly present as anemia and can alter one’s ability to absorb fat soluble vitamins.


We now know and understand that patients with SIBO also tend to have altered immune secretions in the gut, which is proof that SIBO directly alters immune activity in the gut.


What Causes SIBO?


There are three primary causes of SIBO.


1. Digestion delay.  Our gut is a smooth muscle that contracts to propel the ingested food along its pathway.


It’s vital that there’s no stagnancy in the intestine, as disruption of digestion encourages bacterial overgrowth and prevents excess bacteria from being cleared out of the small intestine.


2. Fast Digestion.   On the other hand, if food passes through the bowel too quickly, such as in short bowel syndrome, it can also be a problem since there is not enough time for proper digestion and absorption.


3. Altered digestive secretions.  We need sufficient stomach acid, bile, and enzymes to maintain healthy bacterial levels in the small intestines.


If those digestive secretions are compromised, an imbalance results and bacteria flourishes.


Triggers for SIBO


We don’t know what triggers SIBO, but research implies the following can serve as a triggers for SIBO:


  • Hypochlorhydria (low production of hydrochloric acid in the digestive track)
  • Chronic antacid therapy (especially with PPIs or H2-blockers)
  • Gastroparesis (motility of the stomach is abnormal or absent)
  • Gallbladder/bile dysfunction
  • Pancreatic enzyme deficiency
  • Slow-transit constipation
  • History of bulimia
  • Multiple courses of antibiotics
  • Ileocecal valve incompetence
  • Diet rich in sugars and simple carbohydrates
  • Heavy alcohol use
  • Stress

Predisposing Factors for SIBO


1. Hypothyroid.  Because thyroid function is vitally important for all cells of the body including the cells of our gut, hypothyroid can cause digestion delay.


2. Diabetes.  Diabetes causes oxidative damage due to high blood sugar, which can lead to deterioration of vision, kidney function, and peripheral blood vessels, ultimately slowing the digestive delay.


3. Chronic stress. When the body is stressed, its gut function is altered.  This also affects the enteric nervous system (part of our nervous system responsible for our digestion) which controls the propulsion of food along the digestive tract.


4. Immune system compromise. SIBO compromises our immune system by reducing secretory IgA secretion in the gastrointestinal tract which assists in preventing bacterial proliferation.


5. Abdominal adhesions.  Abdominal adhesions otherwise known as scar tissue, can result from chronic inflammation (e.g. Crohn’s Disease), infection, or surgery.

This can in turn create an obstruction or disruption to the intestines and/or impair the digestive capability, both of which can predispose one to SIBO.

Small intestinal bacterial overgrowth has become a significant health problem in clinical practices.


SIBO in patients with irritable bowel syndrome (IBS) range from 4-78% (higher prevalence in diarrhea-predominant IBS)[1] and is understood to be almost as high in many other disorders of the digestive tract.


Clinical definition of SIBO is an increase in the concentration of bacteria of more than 100,000 colony-forming units per mL in the small intestine.


SIBO can lead to malabsorption and malnutrition that stimulates celiac disease, as well as milder symptoms similar to IBS.


Either are indicative of a disruption of natural protective mechanisms of the gut. These factors predispose the gut toward dysbiosis.


Testing For SIBO


Testing for SIBO is most often through a less invasive breath test that detects both methane (CH4) and hydrogen sulfide (H2S) gases. One of two sugars (glucose or lactulose) induces the gas production.


Since methane and hydrogen sulfide are not produced as metabolic byproducts of human cells, the expired gas during a three-hour breath test is generated by bacterial fermentation as the provoking solution travels through the gut.


Treatment of SIBO


Conventional treatment for SIBO is antibiotics, however, it’s also so accepted that the response to these regimens are variable and inconsistent.


A study from Johns Hopkins Hospital compared the effects of rifaximin (1200 mg/day) to daily, concentrated herbal therapy for 4 weeks in patients with newly diagnosed SIBO.[2]


The herbal therapy intervention included a concentrated berberine formula and concentrated aromatic essential oil formula.


Study results are as follows:

  • Herbal therapies were as effective as rifaximin for resolution of SIBO.
  • For rifaximin non-responders, the herbal therapies were as effective as triple antibiotic therapy for SIBO.
  • Many adverse side effects were reported with the rifaximin treatment, while only 1 case of diarrhea was associated with the herbal therapy intervention.


In conclusion, the herbal therapies demonstrated equal effectiveness for SIBO resolution as the antibiotics regimen.


Furthermore, the herbal therapies were associated with significantly fewer, milder side effects.[2]

Alkaline Solution for SIBO


As a Lupus patient, I’ve struggled with IBS, diverticulitis, and SIBO over time.  I’ve been given various antibiotic treatments for such symptoms which caused worse side effects.


Overall, this caused me to be more susceptible to the initial issue of leaky gut.


The link between autoimmunity and gut permeability is valid and as such, we must start to heal our leaky gut to reverse the symptoms of autoimmunity.


The prevalence of autoimmune patients are astounding.  We are seeing a surge of autoimmune disorders clinically and we need to think differently about addressing our symptoms.


The old paradigm of putting a temporary bandaid over a problem is no longer viable.   As patients, we must be proactive in our healthcare to take responsibility rather than be subjected to ineffective treatment protocols.


What makes logical sense is to REMOVE the triggers, REPLENISH the gastric secretions such as hydrochloric acid, pancreatic enzymes, herbals, and probiotics, and REBALANCE your lifestyle by decreasing stress, eating healthy whole foods, and exercising.


We’ve got the full blown Alkaline protocol I’ve created and applied to myself as well as thousands of my patients. My hope is to help you not only reverse your symptoms but thrive in your life.
