Antibiotics are typically prescribed as a cure for many conditions because they kill bacteria infections that cause disease. Unfortunately, antibiotics do not target only bacterial infections. Antibiotics also destroy the good bacteria in the gut. Therefore, it is not unusual for the onset of IBS to follow antibiotic treatment.
The good bacteria is called the Microbiome. Scientific research shows that diversity of the microbiome is critical for good health and preventing diseases such as obesity and diabetes. The research is also very clear that the diversity of the microbiome is critical for intestinal function and curing IBS.
If you have a history of antibiotic treatment for any reason you should regularly eat fermented foods and fiber that promotes the growth of the microbiome, or good bacteria in the gut. Supplementation with probiotics is also important.
