Figure 1. Prevalence of hair loss 12 months after bariatric surgery in those younger and older than 45 years of age, with or without a
prescription for supplements. The prevalence of hair loss regardless of age and gender among subjects with or without a prescription
for supplements was significant at P < 0.00001.

In conclusion, hair loss is a frequent postoperative complication after BS in morbidly obese individuals.
Based on the results, the variable addition zinc + iron might be one of the predictors of hair loss, although
further research is needed to demonstrate the correlation between preoperative status of nutritional
deficiency and postoperative remission in bariatric subjects. Therefore, there is global need for monitoring
nutrient status in these patients. Most of these deficiencies might be preventable and treatable with high-
dose supplementation. With increased awareness of the potential nutritional consequences of BS, life-
threatening complications related to nutritional deficits may be avoided.
