Panniculus

The panniculus (often incorrectly referred to as pannus) is a dense layer of fatty tissue consisting of excess subcutaneous fat within the lower abdominal region. Panniculi can form after rapid weight loss, as seen with strict exercise plans, in which case the abdominal fat is successfully reduced, but the then excess skin hangs loosely over the area. (It can be a result of obesity in and of itself, hence the acronym FUPA: Fatty Upper Pelvic Area, and can even be mistaken for a tumor or hernia.) Abdominal panniculus can be removed during abdominal panniculectomy, a type of abdominoplasty. A panniculus can also be the result of loose tissues after pregnancy or massive weight loss.
