Unpacking SIBO: The Hidden Culprit behind IBS
As a naturopathic doctor, I focus a lot of my practice in working with patients who suffer from Irritable Bowel Syndrome (IBS). This condition can cause a range of uncomfortable digestive symptoms, including bloating, gas, abdominal pain, and inconsistent bowel movements. While IBS and Small Intestinal Bacterial Overgrowth (SIBO) may seem like separate issues, recent research has uncovered a link between the two that can help us better understand and treat these conditions.
SIBO occurs when there is an overgrowth of bacteria in the small intestine, leading to symptoms similar to IBS. Studies have shown that up to 84% of IBS patients also have SIBO, suggesting that the two conditions may be intertwined. In fact, one study found that treating SIBO in IBS patients led to a significant reduction in symptoms (1).
The exact cause of SIBO is difficult to pinpoint (and often different for each person), certain factors have been identified as contributing to its development. These include a lack of stomach acid, slow motility of the small intestine, and immune dysfunction (2). Interestingly, these factors are also associated with IBS. This suggests that there may be an underlying link between the two conditions, and treating SIBO may help alleviate IBS symptoms.
As a naturopathic doctor, I believe in treating the root cause of health issues, rather than just the symptoms. In the case of IBS and SIBO, this means addressing the overgrowth of bacteria in the small intestine. One way to do this is through the use of natural antimicrobial agents, such as oregano oil, garlic, and berberine. These agents can help to reduce the number of bacteria in the small intestine, leading to a reduction in symptoms.
Another approach to treating SIBO is through the use of the low FODMAP diet. This diet restricts certain types of carbohydrates that are fermented by bacteria in the small intestine, leading to gas and bloating. While the low FODMAP diet is not a long-term solution, it can be helpful in reducing symptoms while other treatments are implemented.
In conclusion, SIBO is a hidden culprit behind IBS symptoms that cannot be ignored. As naturopathic doctors, we can address the root cause of these conditions through natural interventions such as antimicrobial agents and the low FODMAP diet. By treating SIBO, we can help our patients find relief from their IBS symptoms and improve their overall digestive health. If your curious to find out if you have SIBO and if it’s causing your IBS symptoms, let’s chat.
