Hi and welcome to our forum! Your single lateral view photo of your upper abdomen does not provide enough information to make a determination as to the cause of your abdominal fullness, and, as there are no photos of your buttocks, I cannot comment upon efficacy of a BBL.. Abdominal fullness may be the result of your anterior abdominal wall musculature being stretched out, as the result of previous pregnancy or after dramatic weight loss (treated with abdominoplasty), the presence of excess superficial fatty tissue (treated with liposuction), or excessive visceral fat, the intra-abdominal fat that surrounds your internal organs (treated with diet and exercise). Height and weight data is extremely important. BMI (body mass index equals weight in kg / square of height in meters) is one criterion to determine the anticipated results of a cosmetic surgery. You can find BMI calculators on the internet. If your BMI is greater than 30, the cosmetic result will not be optimal. If your BMI is greater than 35, your operative risk will rise. In our practice we recommend a BMI of less than 30. We recommend that you be at a healthy comfortable stable body weight at the time of surgery. The cosmetic effect improves with lower BMIs. If overweight, we recommend a regimen of diet and exercise to reach a safe and healthy body weight. If not achievable, one may consider a bariatric procedure such as a gastric sleeve to achieve dramatic weight loss. This procedure is performed by a bariatric surgeon on an outpatient basis. This procedure will result in marked reduction of visceral body fat and body weight overall. Liposuction is restricted to 4000 cc of supernatant fat here in Florida for patient safety. That correlates to ~ 6-8 pounds of fat. Without more photos, I cannot determine if it would be sufficient to achieve your desired result with BBL. It will not appreciably affect your internal visceral fat content. Visit a board certified plastic surgeon for in-person evaluation and discussion. Best wishes...
