Abstract

Background: Obesity being a multi-organ disease also affects the skin. Bariatric surgery results in the improvement or remission of many obesity-related comorbid conditions, as well as sustained weight loss and improvement in quality of life. After bariatric surgery, both positive and negative impacts on the skin are seen. Studies have reported improvement in many skin conditions. The present study was conducted with the aim to find cutaneous changes in obese patients before and after bariatric surgery were assessed. Methods: This prospective, observational study included 61 obese subjects who had undergone bariatric surgery. clinical findings of skin, nails, and hair before and after bariatric surgery at 3 months, 6 months, and 9 months follow-up were also recorded. Results: Mean age of the subjects was 44.4±13.284 years. Bariatric surgery resulted in a significant decrease in BMI [40.3 (38.25-42.70) vs 32.0 (30-35) kg/m2]. The median of % effective BMI change was 20.46% (17.12%-24.66%) kg/m2. Amongst obese subjects, the most frequently seen skin condition was acanthosis nigricans [17 (27.9%)] followed by acrochordon [15 (24.6%)] and intertrigo [10 (16.4%)]. Our study showed no significant difference in the prevalence of various skin conditions/diseases before and after the bariatric surgery except for intertrigo, tinea corporis, and striae rubra. Conclusions: various skin/hair/nail conditions and/or diseases develop amongst obese individuals, acanthosis nigricans, acrochordon, intertrigo, seborrheic dermatitis, chronic telogen effluvium, onychomycosis, and longitudinal ridges are common. Weight loss after bariatric surgery provided improvement in skin conditions/diseases. 
肥胖患者减肥手术前后的皮肤变化
背景:肥胖是一种多器官疾病,也会影响皮肤。减肥手术可以改善或缓解许多与肥胖相关的合并症,以及持续的体重减轻和生活质量的改善。减肥手术后,对皮肤的正面和负面影响都可以看到。研究报告了许多皮肤状况的改善。本研究的目的是发现肥胖患者在减肥手术前后的皮肤变化。方法:这项前瞻性观察性研究包括61名接受过减肥手术的肥胖受试者。随访3个月、6个月和9个月,记录减肥手术前后皮肤、指甲和头发的临床表现。结果:患者平均年龄44.4±13.284岁。减肥手术导致BMI显著下降[40.3 (38.25-42.70)vs 32.0 (30-35) kg/m2]。有效BMI变化的中位数为20.46% (17.12%-24.66%)kg/m2。在肥胖人群中,最常见的皮肤状况是黑棘皮病[17例(27.9%)],其次是背索病[15例(24.6%)]和三角区[10例(16.4%)]。我们的研究显示,除三节间肌、体癣和脐纹外,减肥手术前后各种皮肤状况/疾病的患病率无显著差异。结论:肥胖人群会出现各种皮肤/毛发/指甲状况和/或疾病,黑棘皮病、肢索、肌间质、脂溢性皮炎、慢性休止期渗出、甲癣和纵脊是常见的。减肥手术后的体重减轻改善了皮肤状况/疾病。
