Study summary

The prevalence of obesity nearly tripled from 1975 to 2021, resulting in liposuction, as an effective shaping method, to be performed more frequently. Liposuction is a surgical procedure that uses a specialized instrument to suck fat fragments in the subcutaneous fat layer through a small incision. Analyzing a large sample sizes of patients who had liposuction, we found that some female patients underwent menstrual irregularity after liposuction. In 2004, Carolyn et al. reported several cases in which there was a connection between liposuction and an early onset of menses. Further studies showed that an early onset of menses may be related to the volume of adipose tissue extracted, the amount of anesthesia given, the area of liposuction, and body weight. However, the sample of that study was small, as there were only 17 cases included in the statistical model, and there are few articles in which the impact of liposuction on menses has been studied. To better understand whether menstrual irregularity will occur after liposuction, patients with postmenopausal or preoperative menstrual irregularity were excluded, leaving a sample of 518 female patients to be reviewed. A better understanding of the impact of liposuction on menses may help clinical doctors predict the underlying risk of menstrual irregularity after liposuction and identify individuals at higher risk. The findings may contribute to further understanding of menstrual irregularity.
