Hi and Happy New Year! You are considering abdominal lipocontouring and concerned about risks and regaining the fat removed. These are both excellent questions. First, the risks associated with liposuction are usually rare in well experienced hands, and include seroma (fluid collections) and skin injury, especially with more aggressive liposuction. If conservative, the "sequelae" (expected phases of healing) will likely include some swelling and bruising, that lasts for a few weeks. With respect to gaining the fat back that depends on your diet and corresponding weight changes. If you watch your weight daily and maintain it within 5 lbs of your weight at about 6 months after surgery, the fat around your abdomen will not come back. On the other hand, if you gain weight, you will more likely see an expansion of fat cells "throughout your body", including the abdominal area where you had the liposuction. Since all the fat cells were not removed with safe liposuction from the abdomen, the remaining fat cells can expand as normal fat cells do with high caloric intake and weight gain.
