Hi Aayush0505, Thank you for your question about losing 30 kg/66 lbs in the past few months, having loose skin in my lower stomach, and whether you need surgery. Thank you for your pictures. First, we should analyze your pictures to determine the best procedures. You have cutis pleonasmus (excess skin) and dermatocholosis (loose skin) of your lower abdomen. You do not have lipodystrophy or excess fat. Therefore, you have a skin issue, not a fat issue. Since liposuction removes fat, not skin, it would not be the best surgery for you. Therefore, the best procedure for you would be a tummy tuck (abdominoplasty). Dermarolling will not help. Save your money and time. A tummy tuck is performed under general anesthesia and takes about three to four hours to complete. An incision is placed low on the abdominal wall. Tissue dissection is performed to the umbilicus. An incision is placed around the belly button, and the belly button is dissected from the abdominal wall. Tissue dissection is carried to the sternum. The rectus muscle is examined. Usually, the rectus muscle is plicated or sutured together to flatten the abdomen and correct for rectus diastasis. In your case, your rectus muscle is in good shape; you do not need muscle plication. The abdominal wall skin is redraped, and the excess abdominal wall skinand fat are removed. Two drains are placed and are usually removed after 10 to 14 days. Most patients can return to activities of daily living after about two weeks. Most patients are able to return to their regular exercise routine after about six to eight weeks. Most plastic surgeons offer free virtual or in-office physical consultations. Therefore, explore what other plastic surgeons have to say. If you have any more questions regarding tummy tucks, abdominoplasties, or abdominal liposuction, contact an experienced plastic surgeon. Since the tummy tuck surgery is a big procedure, please seek an experienced, board-certified plastic surgeon with significant experience in performing tummy tucks. Do your research. If you cannot find an experienced tummy tuck plastic surgeon in your neighborhood, consider traveling out of state. Sincerely, Dr. Katzen, MD, MBA, FACS, FICS.
