Elective usually means "by choice." The operation isn't needed to save a life or keep function. It's often used to describe operations done for cosmetic reasons. This can include face-lifts, tummy tucks, or other plastic surgery.

Today there are many more elective operations possible compared to just 10 years ago. People with poor vision can have LASIK surgery to correct their eyesight. Some dental work is also considered elective. It may make the person look better, but it won't improve chewing or other functions.

Elective surgery for a herniated disc is more common in countries like Canada where they have national health insurance. Only the patients with extreme symptoms will have the operation. Everyone else will be treated with more conservative methods until a doctor and operating room are available.
