What is this hump behind my neck and is liposuction a better solution to fix it? (Photo)

The hump that is behind your neck is probably an extra buildup of fat, technically called the buffalo hump. This protruded fat is generally linked with obesity issues or an underlying condition and can possibly reduce one’s self-esteem.
Although this condition is generally not severe and does not have a huge impact on an individual‘s health this can be a very frustrating concern from an aesthetic point of view, especially for someone who is body conscious. If getting rid of this buffalo hump is what makes you gain self-confidence, then you have all the freedom to choose what you want to do.
There are various cosmetic surgeries to remove the buffalo hump that are viable, if diet and exercise have not shown any results. Upon ineffective outcomes your surgeon will generally recommend a liposuction where the stubborn fat pockets at the back of your neck are eliminated. One of the biggest benefits of liposuction technique is that there will be minimal scarring and quick healing. There are a number of liposuction techniques that are used to remove buffalo humps, each having their own benefit and limitations - that are customised according to your concerns.
