With the increasingly sedentary lifestyle, weight-related health issues have been on the rise. Los Angeles being the entertainment and recreational capital of the country can often be overwhelming for some people. For residents of Los Angeles, CA, struggling with health problems, we have compiled a list of the five most experienced and accomplished bariatric surgeons whom you may consult for the best possible outcome.

All the information you see here is based on our analysis of internet reviews across the seven major review platforms most used by consumers during their healthcare provider selection. The platforms we selected are Google, WebMD, Yelp, HealthGrades, Facebook, RateMDs, and Vitals. The analysis algorithm uses the compiled data of average score, recency of reviews, number of reviews, and the sentiment expressed in the written comments. It then assigns weight to each parameter based on the available research on how consumers use reviews in their doctor selection process. This report is designed to help identify the doctors with the best overall review score in an area and does not reflect the doctors' competence.
