Skin changes after bariatric surgery

Abstract

Today, obesity is considered an epidemic all over the world and it is recognized as one of the major public health problems. Bariatric surgery is considered an appropriate therapeutic option for obesity with progressively increasing demands. The changes resulting from massive weight loss after bariatric surgery are related to numerous complications. This article will present the dermatological alterations that can be found after bariatric surgery. They will be subdivided into dermatoses that are secondary to metabolic and nutritional disorders, those derived from cutaneous structural modifications after major weight loss and the influence the latter may have in improving of certain dermatoses.

It involves creation of a bypass around the duodenum and most of the jejunum, sites where the majority of vitamin and mineral absorption occur 1. Following the procedure, patients are required to supplement vitamins and micronutrients for life.…”

“…Even with supplementation, patients are at risk for deficiencies of vitamin B12, folate, iron, zinc and many of the B vitamins 2. Deficiencies of zinc, selenium, vitamin B2 and vitamin B6 are associated with skin rashes 1 3…”

“…Patients at risk for malabsorption include those with inflammatory bowel disease, celiac disease, chronic diarrhoea and those who have had surgical resection of the bowel or gastric bypass surgery 4. Wasting of zinc has been shown to occur in the setting of alcohol abuse, systemic infection, burns and neoplasms 1 4. Mahawar et al reported that up to 68% of gastric bypass surgery patients become deficient in zinc 3.…”

Peculiar Skin Rash After Laparoscopic Sleeve Gastrectomy

“…Many approaches have been used to reduce obesity and its catastrophic effects on today’s society, including education, dieting, exercise, and drugs.
