In patients with diarrhoea-predominant IBS, what is often found regarding bacterial presence?
Understand the Problem
The question is asking about the relationship between bacterial presence and patients with diarrhoea-predominant Irritable Bowel Syndrome (IBS). It seeks to identify the correct statement regarding the bacterial populations in such patients.
Answer
An imbalance of gut bacterial communities (dysbiosis) is often found in IBS-D patients, with enrichment of certain bacteria.
In patients with diarrhea-predominant IBS (IBS-D), an imbalance in gut bacterial communities, known as dysbiosis, is often found. This can include the enrichment of specific bacterial genera like Fusicatenibacter, Streptococcus, and Klebsiella, or the presence of small intestinal bacterial overgrowth (SIBO).
Answer for screen readers
In patients with diarrhea-predominant IBS (IBS-D), an imbalance in gut bacterial communities, known as dysbiosis, is often found. This can include the enrichment of specific bacterial genera like Fusicatenibacter, Streptococcus, and Klebsiella, or the presence of small intestinal bacterial overgrowth (SIBO).
More Information
Studies indicate that gut dysbiosis, characterized by an imbalance of microbes, plays a crucial role in the symptoms of IBS-D, which might include an increase in harmful bacteria or a reduction in beneficial ones.
Tips
A common mistake is not considering the potential role of small intestinal bacterial overgrowth (SIBO) as a contributing factor to the symptoms.
