Can you have breast implants if you are underweight a little?

A low BMI is not a problem as long as you are overall healthy and have realistic expectations.  Being thin will mean your implants will be visible and any rippling will be more obvious compared to a person who has more fat to cover up the implants

Thanks for your question.  Being underweight is not neccessarily a contraindication to breast augmentation surgery.  However, a plastic surgeon will need to determine whether there is enough breast tissue to cover implants.  If there is very little  tissue over the implants, there will be higher likelihood of problems like seeing the implants, rippling, etc.
