CONCLUSION
This is the first study in the literature questioning bowel habits,
physical activity, dietary fiber intake, and IBS all together in acne
vulgaris patients. It is striking that coffee consumption is related
with acne vulgaris. Although a significant relation between acne
vulgaris and bowel habits or nutritional characteristics cannot be
demonstrated, further large sample sized studies are needed on this
subject, as there is strong evidence about brain–gut–skin axis
existence.
There is no conflict interest.
There is no financial disclosure.
The data that support the findings of this study are available from the
