Panniculus

Panniculus is a medical term describing a dense layer of fatty tissue growth, usually in the abdominal cavity. It can be a result of morbid obesity and can be mistaken for a tumor or hernia. Abdominal panniculus (the "apron" in layman's terms, also known as the "FUPA" or "FUVA") 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.

Grading of abdominal panniculus

 * Grade 1: Panniculus barely covers the hairline and mons pubis but not the genitalia.
 * Grade 2: Extends to cover the genitalia.
 * Grade 3: Extends to cover the upper thigh
 * Grade 4: Extends to cover the mid thigh.
 * Grade 5: Extends to cover the knees or beyond.
