I've seen a lot of doctors giving exact BMI ranges for their eligibility requirements for lipo. This is just their individual preferences, and they are certainly entitled to their opinions and guidelines about whom they would like to operate on. However, when you're talking about whether someone is healthy enough to undergo a lipo procedure, BMI is not the be-all end-all number that gives a clear indication of health. First of all, BMI is a ratio between height and weight. Muscle weighs more than fat, so bodybuilders tend to have very high BMIs, despite usually being very healthy. In my practice, I have a range as a guideline (typically 28-34), but I often see patients who fall outside that range for consult and have them get labs drawn so I get a complete view of their health before deciding whether they are healthy enough for liposuction. If they are not, then there's the opportunity for us to work together towards that goal.
