Obesity has gone from being an individual concern to becoming a global public health crisis. With more than 800 million people affected, according to the World Health Organization (WHO), this chronic disease goes beyond an aesthetic problem: it increases the risk of developing non-communicable diseases such as type 2 diabetes, cardiovascular disease, hypertension and certain types of cancer.
A growing problem
Since 1975, obesity has tripled worldwide. In Latin America and the Caribbean, the situation is particularly worrisome. Data from the Pan American Health Organization (PAHO) reveal that 60% of the adult population and 33% of children and adolescents are overweight or obese. This exponential increase is due to several factors, including changes in diet, increased consumption of ultra-processed products and an increasingly sedentary lifestyle.
More than a question of will
Contrary to popular belief, obesity is not simply the result of bad habits or lack of discipline. It is a multifactorial disease influenced by genetic, metabolic, environmental and behavioral aspects. The National Heart, Lung, and Blood Institute (NHLBI) has identified at least 15 genes linked to obesity. Although genetic predisposition can increase risk, adopting a healthy lifestyle can help mitigate its impact.
In addition, certain medical conditions such as metabolic syndrome or polycystic ovary syndrome can also promote weight gain. In these cases, a comprehensive medical approach is essential to achieve a healthy weight.
Consequences on health and quality of life
Obesity not only affects physical health, but also emotional and social health. People with obesity face an increased risk of developing:
- Type 2 diabetes: Excess body fat can lead to insulin resistance, making it difficult to control blood sugar.
- Cardiovascular diseases: Obesity is closely related to hypertension, high cholesterol and the risk of heart attack.
- Certain types of cancer: Studies have linked obesity to an increased risk of breast, colon, endometrial and kidney cancer.
- Sleep disorders: Sleep apnea is common in people with obesity and can lead to chronic fatigue and other health problems.
- Joint problems: Excess weight puts additional stress on the joints, increasing the risk of osteoarthritis and chronic pain.
On an emotional level, many people with obesity face discrimination, stigmatization and low self-esteem, which can lead to depression and anxiety.

Obesity is preventable and treatable, but requires a multidisciplinary approach. Some key strategies include:
- Balanced diet: Prioritize natural foods, rich in fiber, proteins and healthy fats, and reduce the consumption of sugars and ultra-processed foods.
- Regular physical activity: Performing at least 150 minutes of moderate exercise per week helps maintain a healthy weight.
- Personalized medical care: Consultation with health professionals, including nutritionists, endocrinologists and psychologists, is essential to address obesity from a comprehensive approach.
- Education and awareness: Public policies should encourage healthy environments, regulating ultra-processed food advertising and promoting physical activity from childhood.
- Emotional support: Combating the stigma associated with obesity is crucial for affected individuals to seek help without fear of social judgment.
World Obesity Day reminds us that this disease is not a matter of image, but of public health. Its impact transcends appearance and affects the quality of life of millions of people. The solution lies not in individual guilt, but in a collective response that addresses the root causes of this global crisis. With education, health policies and professional support, we can work towards a world where obesity is no longer a growing threat.
