If you are 18+ and not pregnant or currently breastfeeding, then you can be suitable for breast augmentation. Particularly you must also take account of whether you are not fighting any other illnesses or infections at the time of consultation/procedure to ensure that all safety precautions are met.
Specific to your breasts, you can undergo breast augmentation if you have:
✔️ Small Breasts
✔️ They are sagging due to age or weight loss
✔️ They are not symmetrical ie. one is larger than other
Your consultant / surgeon will guide you on further details before you take up breast augmentation including help in choosing correct implants. No smoking and realistic expectation is also expected which helps in speedy wound healing.
