Reath says that there aren’t a lot of major health risks if you're in good health. Still, problems can happen.
Liposuction, for instance, can be done safely as long as only a certain amount of fat is being taken out. The risk increases, he says, if the amount becomes excessive.
Doctors also have to be careful not to do too much of anything at one time. "Surgeon fatigue is a consideration," Reath says. "No one is as sharp in their eighth hour as they are in their first hour."
Scar tissue and tissue that dies during the healing process can become an unhealthy issue after multiple surgeries. Breathing problems can happen after too many nose surgeries, and people can have dry corneas, which cause eye damage, from eye lifts. Infection is also a risk with any surgery.
