Obesity and Weight Stigma in Switzerland: An Underestimated Challenge with Far-reaching Consequences

Obesity in Switzerland: Misunderstood and Overlooked New findings from the 2025 YouGov Obesity Study reveal that although around half of the respondents (51%) claim to know the BMI associated with 'obesity,' about half of this group incorrectly estimates the threshold. This points to gaps in knowledge that can lead to the insufficient seriousness of health risks. At the same time, the study shows: obesity is prevalent in the population. The findings underline the need for better information and empathetic communication that conveys facts while respecting the reality of those affected.

The Health Implications Underestimated Obesity is often considered merely an aesthetic problem, yet the results show it can be associated with serious health consequences. Among adults with a BMI over 30, 60% report at least one chronic disease, including cardiovascular diseases, diabetes, and orthopaedic complications. Older adults (60–79 years) are particularly affected by these physical health issues, while younger adults (18–29 years) experience increased psychological strains due to feelings of shame, anxiety, and depression.

"These results raise a critical question," says Selina Steinmann, Head of the Health Platform iMpuls. "How can we as a society provide good support when many people with obesity are already living with health challenges and awareness of this chronic disease is still limited? It's worth doing more: making reliable information accessible and fostering understanding – to support the health of many sustainably."

Far-reaching Consequences of Weight Stigma The stigmatization of people living with obesity is deeply rooted in Swiss society – across almost all areas of life: at work, in schools, in public, in the healthcare system, and even among friends and family. Alarmingly, 76% of all respondents report weight-related discrimination, and nearly half of those living with obesity have themselves already been stigmatized (frequently or occasionally).

Respondents cited personal stigma examples like: "As an overweight person, you're quickly labeled as lazy." "In the airplane, when the seatbelt is too short." "In my primary school class, there was a girl who was overweight and was teased by others as a result." "In the pool, derogatory remarks were made about an overweight woman." "During the application process, i.e., women were hired based on their appearance." "My mother occasionally makes pointed remarks." "In the media, women are constantly evaluated based on their bodies, it's everywhere." "In the hospital, people were gossiping about me, while I could hear them through the curtain." "My doctor said: 'Lose 20 kg first, then we will see if obesity treatment is necessary.'"

About 40% of people living with obesity say that stigmatization undermines their self-confidence and their willingness to seek help. Younger adults (18–29 years) are particularly affected and report more weight-related stress and shame.

"The stigmatization of people living with obesity is not merely a side effect, but an integral part of the health burden," says Anne Mette Wiis Vogelsang, General Manager, Novo Nordisk Switzerland. "Are we ready to live in a society where children are bullied at school because of obesity, adults face discrimination in the workplace, and those affected feel blamed even when seeking help?"

For a More Inclusive Society: Structural Solutions Are Crucial Despite the availability of health-promoting infrastructures – such as sports facilities and nutritional counseling – weight loss remains a complex challenge for those living with obesity. According to the study, 85% of respondents with obesity have already tried to reduce their weight. However, many report limited success. Lack of motivation, time, and work-related stress were identified as central barriers to a healthy lifestyle. These barriers are discouraging and reinforce the feeling that progress is difficult to achieve. Obesity is a complex chronic disease influenced by genetic, psychological, hormonal, and environmental factors.

Respondents were asked to name measures that they believe could reduce discrimination and prejudice against people living with overweight or obesity and promote a stigma-free environment. The most common responses were:

Awareness-raising in schools (56%) Public information campaigns (36%) Workplace initiatives and targeted awareness (27%)

iMpuls, along with Novo Nordisk, is working to bridge the knowledge gap. Through initiatives like the iMpuls platform, it is ensured that prevention does not remain theoretical but offers practical and inclusive tools for all. The partnership promotes sustainable approaches for healthier living.

About the 'Obesity Study 2025' The 'Obesity Study 2025' was conducted by YouGov as part of the partnership between iMpuls and Novo Nordisk. The online survey was conducted between November 17 and 28, 2025, among the Swiss resident population aged 18 to 79 via the YouGov portal. The survey included 1,500 interviews, including a representative sample of 1,000 people, as well as extensions to subgroups, such as Ticino, to also statistically evaluate possible differences within these groups.
