A new study suggests that people who undergo weight-loss surgery experience better mental health, but not because of the pounds they shed. Instead, the major factor appears to be a significant drop in the societal judgment and bias (stigma) they face due to their weight. This finding was recently published in the journal Health Psychology. How Being Judged Affects Our Mental And Physical Health Being judged and treated unfairly because of one's weight actually causes many of the physical and mental health problems that people with obesity face. The study found that when people felt less judged after their surgery, they started to have healthier eating habits and felt better mentally. But if they kept feeling judged even after surgery, they had a higher chance of feeling sad, worried, or developing eating problems. For the study, researchers looked at the mental well-being and habits of nearly 150 people before their weight-loss surgery and then again 18 to 36 months later. What they found was that, generally, people felt much less shame, blame, and guilt about their body size in the years after surgery. The amount that this feeling of being judged went down was very impressive. It was a bigger change than what doctors usually consider meaningful for someone's life and how they feel. This big drop in feeling judged was directly connected to people feeling less worried, less sad, and having fewer eating issues like overeating. Why Feeling Accepted Matters More Than Just Losing Weight The study also showed that losing weight itself wasn't strongly linked to feeling better mentally. This suggests that how other people treat individuals with a lot of weight, rather than just the extra weight itself, has a huge impact on their mental and physical health. About 40% of the people in the study still faced problems with weight-related judgment, and these ongoing issues made them more likely to have mental health concerns. The researchers believe that while losing weight helps in many ways, this change in how society treats people might be even more powerful for their mental health and overall quality of life over time. Weight-Loss Surgery and Mental Health Published in the StatPearls medical journal, a 2024 article explained that while weight-loss surgery, also called bariatric surgery is a common as a way to treat obesity, it also has many complications one must consider. It's also important to understand that it can bring some mental health challenges. Patients might feel unhappy if they don't lose as much weight as they hoped, which can make any emotional difficulties worse. After weight-loss surgery, some common mental health problems that can arise include depression, anxiety, and worsening of existing eating disorders. Patients might also develop new eating habits or switch addictions (for example, from food to alcohol or gambling). In rare cases, more severe issues like psychotic disorders or, very notably, an increased risk of suicide, can occur. More Studies Are Needed It's worth noting that all the people in this study were treated at one specific hospital. The researchers think it's important to do more studies with people from different areas to be sure these findings are true for everyone.
