In this study, hair loss after laparoscopic sleeve gastrectomy was associated with zinc and iron levels, even within normal ranges, and a combined variable of zinc and iron predicted susceptibility to hair loss.

This study found that temporary hair loss is common after laparoscopic sleeve gastrectomy, and biotin supplementation showed low effectiveness in preventing this hair loss.

This study found that hair loss after metabolic and bariatric surgery peaks at 3 months and improves by 6 months, with iron deficiency and female sex being strong predictors of hair loss.

This study observed that laparoscopic sleeve gastrectomy significantly reduced BMI and helped improve or eliminate certain obesity-related comorbidities over six months, with a low incidence of postoperative complications.

This study found that bariatric surgery patients with a prescription for supplements had fewer nutrient deficiencies and less hair loss 12 months post-operation compared to those without supplements.

This study found that vertical sleeve gastrectomy improved metabolic, behavioral, and reproductive symptoms in a rat model of PCOS, suggesting it may be a potential therapy for specific aspects of PCOS.

This study found that 56% of patients experienced hair loss six months after undergoing laparoscopic sleeve gastrectomy, with lower preoperative and postoperative zinc and vitamin B12 levels associated with this outcome.

This study found that postoperative excess weight loss and folic acid levels were independent factors influencing the severity of hair loss after laparoscopic sleeve gastrectomy in obese patients.

This study identified changes in serum albumin and calcium levels one month after laparoscopic sleeve gastrectomy as independent factors linked to hair loss in patients with obesity, highlighting the importance of monitoring these nutritional indicators to reduce postoperative alopecia risk.

This study aimed to assess the safety and effectiveness of laparoscopic sleeve gastrectomy in children and adolescents with obesity, noting the scarcity of data despite emerging evidence of favorable outcomes.

This study found that three-quarters of patients experienced hair loss following laparoscopic sleeve gastrectomy, with female gender, preoperative serum folic acid, and percent excess weight loss as significant risk factors.

This study found that modified laparoscopic sleeve gastrectomy in patients with type 2 diabetes and obesity reduced ghrelin levels, improved glycemic and insulin levels, and resulted in significant weight loss.

In this study, researchers found that patients undergoing one-anastomosis gastric bypass experienced a greater incidence of low serum zinc levels and related symptoms, such as hair loss and delayed wound healing, compared to those undergoing sleeve gastrectomy.

This case report describes a 42-year-old woman who experienced positional vertigo, gradual hearing loss, and tinnitus after undergoing laparoscopic sleeve gastrectomy, suggesting a potential link between these complications and the procedure.

This study found that for obese patients undergoing sleeve gastrectomy, concurrent type 2 diabetes is linked to worsened metabolic but milder reproductive aspects of PCOS and does not hinder the return to regular menstruation one year after surgery.

This study discusses experiences with managing postoperative complications after bariatric surgery, such as psychological disorders, hair loss, nutritional deficiencies, and other issues, highlighting the need for effective interventions to prevent comorbidities while acknowledging the procedure's generally low complication rates.

This study found that protein supplements combined with micronutrients reduced hair loss more effectively after sleeve gastrectomy in women, compared to routine multivitamins alone.

This article outlines the first prospective cohort study examining whether bariatric surgery can induce satisfactory weight loss in obese Koreans, with no new results reported yet.

This study observed that vitamin and iron deficiencies were similarly prevalent in the first post-surgical year for patients undergoing sleeve gastrectomy and Roux-en-Y gastric bypass, except for more frequent vitamin B6 deficiency in sleeve gastrectomy patients.

This study observed that hair loss after bariatric surgery is the most common nutritional symptom linked to iron and protein deficiencies, while the causes of other symptoms remain unclear.

In this study, adolescent patients undergoing laparoscopic bariatric surgery at a specialized center experienced significant reductions in BMI over 36 months, with no major perioperative complications, highlighting the procedure's safety and effectiveness for treating adolescent obesity in experienced settings.

In their review, the authors found no strong evidence supporting biotin's effectiveness as a hair supplement, noting a significant disparity between its popularity and scientific backing, with available studies showing no substantial benefit over placebo.

This study discusses that many patients experience temporary hair loss after bariatric surgery, potentially due to rapid weight loss, surgery stress, and nutritional deficiencies, including shortages of iron, zinc, and other nutrients crucial for hair health.

This study concluded that hair loss is a common issue after vertical sleeve gastrectomy, influenced by serum leucine concentration, and is not typically due to low iron or zinc levels.

In this case report, the authors describe the first documented occurrence of new-onset hypocortisolism after laparoscopic sleeve gastrectomy in a patient, highlighting the need for awareness of this condition among clinicians when patients present with nonspecific symptoms post-bariatric surgery.

This study found that serum amino acid profiles changed significantly following laparoscopic sleeve gastrectomy in patients with obesity, and identified serum leucine levels as an independent risk factor for postoperative alopecia.

This study aims to compare the safety and effectiveness of bariatric surgery versus medical care on ovulation rates in women with PCOS and obesity, as current observational data suggests surgery may improve fertility prospects, but no randomized trial has yet confirmed this effect.

In this study, metabolic surgery led to a weight loss of 10.8 to 12.6 kg and improvement in body composition and HbA1c levels among patients from North-Eastern Romania, with nutritional intervention proving safe over six months.

This pilot study observed that post-bariatric surgery, both zinc and iron deficiencies increased among Iraqi patients, underscoring the importance of lifelong nutritional monitoring and targeted supplementation to address these issues and prevent related complications.

This case series highlights severe micronutrient deficiencies and complications in three patients who did not adhere to follow-up care after Roux-en-Y gastric bypass, emphasizing the importance of regular nutritional monitoring.
