Proton pump inhibitors and dysbiosis: Current knowledge and aspects to be clarified

Figure 1 Distribution of main bacterial families of human microbiota in physiological condition and during proton pump inhibitor treatment. This figure shows the effect of proton pump inhibitor (PPI) treatment on the composition of gut microbiota families. The left side of the figure shows the principal bacterial families under normal physiological conditions; the right side of the figure shows the increase (↑) and decrease (↓) in bacterial families present in the gut microbiota during PPI treatment. PPI: Proton pump inhibitor.
