    ABSTRACT: Bariatric surgery leads to a significant body weigh reduction although it is associated to a higher risk of presenting some nutritional deficiencies. A common complication, little studied and mainly related to zinc deficiency is alopecia. To compare the nutritional status of zinc, iron, copper, selenium and protein-visceral in women with different degrees of hair loss at 6 months after gastric bypass or tubular gastrectomy. The patients were categorized into two groups according to the degree of hair loss: group 1 or mild loss (n = 42) and group 2 or severe hair loss (n = 45). Zinc, iron, copper, and selenium, as well as the indicators of the nutritional status of zinc, iron, copper, and proteinvisceral were assessed before and after 6 months of the surgery. In both groups there was a significant body weight reduction at 6 months post-surgery (-38.9% ± 16.4%). Patients in group 1 presented a significantly higher intake of zinc (20.6 ± 8.1 vs. 17.1 ± 7.7 mg/d) and iron (39.7 ± 35.9 vs. 23.8 ± 21.3 mg/d.), and lower compromise in the nutritional status of zinc and iron than group 2. However, patients in group 2 had lower compromise in the nutritional status of copper. There were no differences regarding the plasma concentrations of albumin. The patients having lower hair loss at six months after surgery had higher zinc and iron intake and lower compromise of the nutritional status of both minerals.
