That’s a really good question.
You may have a certain body fat percentage, but the fat available for harvesting may or may not be sufficient for you to see satisfactory results.
When it comes to fat grafting for the breast area, having more fat definitely helps, but there are other important factors that can influence the outcome of the procedure.
For a start, surgeons need to look at your body's proportion and estimate the volume required before advising if fat grafting should be considered.
Your height and frame will give the surgeon a rough idea with regards to how much volume they need to create a well-proportioned breast.
The maximum cup size you can achieve from this procedure really depends on 3 factors:
1. Volume
The amount of fat harvested from other areas of the body will determine the volume of fat available for grafting. This allows surgeons to assess if there is sufficient fat to achieve a well-proportioned breast.
In some cases where patients do not have sufficient fat for harvesting, I would recommend implants over fat grafting. However, the surgeon will first need to do a personal assessment on such sufficiency of fat.
2. Fat Quality
With fat grafting, not all the fat tissues injected into the breast will survive. Its survival rate is dependent on the quality of the fat tissues.
Good quality fat has a higher survival rate, hence more volume can be retained in the breast after fat grafting and vice versa. Each patient's fat quality is also different and this can be affected by your lifestyle and diet.
3. Skin’s Ability To Stretch
Skin tightness can also limit the amount of fat that can be injected into the breast area. If the breast skin is too tight, then the amount of fat that can be injected into the breast is limited. If there is more skin laxity, then more fat can be injected into the breast. Occasionally, a breast expansion device such as the BRAVA can be used before and after the fat injection procedure if there is such a need.
In general, under optimal conditions, fat grafting can help to increase breast sizes by 1 to 1.5 cup sizes.
I hope my reply helps.
Warmest regards,
