Overweight and obesity: understanding without stigmatizing

IRIS Prévention
23 September 2026
Overweight and obesity are neither a lack of will nor a moral failing: they are complex health realities, which deserve understanding and respect.

Few health topics are as shrouded in stigma as weight. Overweight and obesity are often wrongly reduced to a question of individual will. However, these are multifactorial states, with real health consequences, but also real causes that go beyond simple personal control. Understanding them without stigmatizing is the condition for effective prevention.

1. Health definitions

Overweight and obesity correspond to excess fat mass which can have an impact on health. We identify them in particular by BMI and waist circumference, while keeping in mind the limits of these tools. These are medical questions, not aesthetic ones.

2. Multiple causes

Obesity results from a set of interacting factors: genetics, hormones, environment, diet, sedentary lifestyle, sleep, stress, social context, certain treatments. Reducing this to “will” alone is inaccurate and unfair.

3. Health issues

Excess fat, especially abdominal fat, increases the risk of diabetes, hypertension, cardiovascular and joint diseases. This is what justifies medical attention, based on health and not aesthetic standards.

4. Act without stigmatizing

Weight stigma is harmful: it degrades well-being, discourages and can even make the situation worse. A caring approach, focused on health and not appearance, promotes lasting changes.

    • Talk about health rather than appearance
    • Value progress, not perfection
    • Rely on professional support

Appropriate medical support, respectful and without judgment, is the best path. Every person deserves to be supported, not judged.
