Découvrir la science repenser l'animation sur l'obésité

<p>Obesity. What does that word make you think of? Excess weight? Unhealthy food choices? Limited physical activity? Healthcare burden? Perhaps, but they’re only part of the story. Obesity is a serious problem for world health and today it affects over 600 million people.</p> <p>Mais l'obésité relève d'une science complexe et souvent mal comprise. En termes simples, l'obésité se développe lorsque nous consommons plus de calories que nous n'en dépensons. Au fil du temps, l'énergie excédentaire est stockée sous forme de graisse dans le tissu adipeux, ce qui entraîne une prise de poids.</p> <p>Losing that weight and keeping it off means more than just eating less and moving more. The thing is, our energy balance can be influenced by many different factors, including our physiology, genetics, environment, socioeconomic status, and psychology. And then, there’s the body’s homeostatic system, which controls appetite, energy intake and energy expenditure.</p> <p>Il implique plusieurs zones du cerveau, notamment l'hypothalamus, qui traite les signaux hormonaux et neuronaux provenant d'autres structures cérébrales, du tractus gastro-intestinal et du tissu adipeux. La perte de poids modifie ce système, provoquant une augmentation de la faim et une diminution du taux métabolique. L'estomac libère également une plus grande quantité de l'hormone ghréline, qui renforce la sensation de faim et l'envie de manger.</p> <p>At the same time, the gastrointestinal tract, pancreas and adipose tissue release fewer satiety signals, so the brain doesn’t recognise feelings of fullness. Hormonal shifts like these are partly why people who do lose weight often put it back on, despite their best efforts. Understanding these factors is critical in managing obesity, especially when you consider its complications, including type 2 diabetes, cardiovascular disease, hypertension, dyslipidemia, osteoarthritis, sleep apnea and certain types of cancer.</p> <p>Equally, obesity and excess weight can negatively impact health-related quality of life and decrease life expectancy. But the good news is, with the right care, sustained weight loss is achievable and a 5-10% reduction can make a meaningful difference to an individual’s overall health. People with obesity are motivated.</p> <p>They really do want to lose weight. And they want to maintain that loss to improve their overall health. But patients can’t do it alone.</p> <p>Ils ont besoin d'aide. L'obésité est une maladie chronique qui nécessite une prise en charge à long terme. Et tout commence par une conversation d'un genre différent.</p>
