SIBO (Small Intestine Bacterial Overgrowth): one more illness of the industrial age. It's causes can be many: weak bile that doesnt cleanup our intestine enough, lack of stomage acid due to PPI's or high levels of stress, weakened immune system, high sugar diet, just to mention a few. What everyone agress is that it's really hard to get rid of it, and even modern medicine treatments show low erradicaton rate. The fact that it's divided between SIBO-D and SIBO-C makes healing even more complicated.
To cure SIBO you have to reduce the bacteria population, however you have to be aware that certain antibiotics target certain bacteria, they will rarely be effective against all bacteria, therefore antibacterials have shown to be as effective and in my opinion have lower relapse rate. There are studies on treatment with antibiotics and antibacterials, and while they show similar eradication rate, there are no studies on relapse from each of the treatments, which I think would be significantly better for antibacterials due to their broader targeting of bacteria.
