Gastric bypass surgery is an effective surgical intervention for morbid obesity. However, it is not without risk. Gastric bypass surgery may produce malabsorptive or surgical complications, which can result in nutritional deficiencies as well as syndromes related to bacterial overgrowth in the blind loops of the bowel.

Case Presentation

Severe nutritional deficiencies may occur due to patient noncompliance with the prescribed regimen, or arise secondary to malabsorptive or mechanical surgical complications. We describe a case of a 37-year-old female who underwent gastric bypass surgery and experienced a recalcitrant eczematous eruption with sporadic subcutaneous, purulent nodules which completely resolved after the reversal of her bariatric procedure.


Since 2001, the number of morbidly obese patients who have undergone bariatric surgery has been increasing. As a result, clinicians can expect to more frequently encounter complications that can result from these procedures.
