The time to examine an area after liposuction for permanent lumps or bumps is 3-6 months. In the first few weeks, there will be swelling, bruising and tissue remodeling that is occuring. This will slowly resolve and leave you with your final result. There is a possibility, especially on the tummy, that you may need a touch-up liposuction to smooth out any lumps. This is most common around the belly-button. I think the % of patients that need a touch-up of the abdomen is around 5%. Most touch-ups are easy procedures with very little down-time. Some physicians will do them for minimal cost to the patient. Make sure to ask at your initial consultation about touch-ups, and the cost.
