What you are describing may necessitate a procedure called a panniculectomy to reduce significant skin and fat hanging below the abs. This degree of skin sag is often experienced by those who were or are morbidly obese. Gastric bypass patients often need this type of body contouring for overall hygiene as well as aesthetic considerations As leading tummy tuck San Francisco surgeons, Dr. Liu and his team take pride in helping their patients achieve their desired body contour. We also have extensive experience with facelift, liposuction, breast augmentation and rhinoplasty procedures for patients from San Francisco, San Jose and San Mateo.
