After bariatric surgery, do superficial fat and deep fat decrease differently?

Abstract

Bariatric surgery has recently become popular for treatment of morbidly obese patients, and post-bariatric body contouring surgery has also become more common. Post-bariatric body contouring surgery, from conventional abdominoplasty to lowerand upper-limb contouring, focuses on reducing redundant tissues and reshaping the body. Most body contouring procedures are performed due to a decreased volume of subcutaneous fat and increased skin laxity after massive weight loss. The abdominal area is the most common area for body contouring surgery in massive weight loss patients; therefore, our study focused on abdominal subcutaneous adipose tissue (SAT). Adipose tissue is an active endocrine and immune organ. In an obese state, adipocyte metabolism is impaired and cell homeostasis is broken [1,2]. For this reason, obesity is considered to be an independent risk factor for mortality and a causative factor of several major diseases, including coronary heart disease, hypertension, and various metabolic diseases [3]. Current treatments for obesity range from dietary modifications to surgical treatment. Ryeolwoo Kim, Youngsung Suh, Seungwan Ryu, Mikyung Kim, Daegu Son
