Do some psychological preparations for liposuction on the back. You should know that after liposuction, you will feel blue and slightly numb, and local tissues will have surgical reactions such as edema. According to the liposuction site, there is generally a recovery process of 1 ~ 3 months. You know, liposuction is not a universal way to lose weight, and obese people can't achieve the goal of losing weight by liposuction alone. If the weight exceeds 20% of the normal weight, effective methods such as exercise and diet control are needed to control the weight. Try to change your diet before liposuction on your back. Dinner time should be as early as possible, and the protein and fat content of dinner should not be too high. Before liposuction, you need to know that your physical condition is not suitable for liposuction. Liposuction is not suitable for people with too loose skin. Such patients can choose other plastic surgery to remove excess skin and fat. At the center of the back is the spinous process of the spine, with powerful sacrospinous muscles on both sides, and then outward is the back plane composed of ribs and scapula. The characteristics of back fat are that the fat directly behind is flat and tight, and the fat at the junction with both armpits or quarter ribs is obviously loose and accumulated, which can be touched by hand.
