Bariatric surgery significantly impacts dermatologic conditions in obese patients, often improving issues like psoriasis, hidradenitis suppurativa, and acanthosis nigricans due to weight loss and reduced inflammation. However, it can also exacerbate or trigger conditions such as alopecia and xeroderma, primarily due to nutritional deficiencies. The review emphasizes the dual nature of these effects, highlighting the need for careful postoperative nutritional monitoring and further research to understand the mechanisms involved.
