Figure 4.

The possible relationships between bariatric surgery, persistent organic pollutants (POPs), and physical activity (PA). Physical activity as well as bariatric surgery can promote POPs’ adipose tissue degradation, resulting in an increase in several determinants of POPs’ hazards. The balance between POPs’ release following adipose tissue degradation and POPs’ excretion/transformation may depend on the physical activity modality (aerobic vs. resistance training). Minus and plus signs in green (potential beneficial effects post bariatric surgery), Plus sign in red (potential adverse effects post bariatric surgery).
