What is obesity?
Obesity is a medical condition characterized by excessive body fat that poses a health risk. A person is considered obese when their Body Mass Index (BMI)—a calculation derived from their weight and height—exceeds 30. It's not merely a concern about physical appearance but a significant health issue that increases the risk of chronic diseases such as type 2 diabetes, heart disease, high blood pressure, certain cancers, and more.
It became recognized as a health risk in the 20th century, with the World Health Organization (2024) now classifying it as a global epidemic. This shift reflects a deeper understanding of the health implications of excess weight gain and the complex interplay of factors contributing to obesity.
What causes it?
Obesity's causes are multifaceted, including genetic predispositions, lifestyle choices, environmental factors, and psychological conditions. Modern diet and lifestyle patterns, characterized by high-calorie diets and physical inactivity, significantly contribute to the rising prevalence of obesity. Recognizing obesity as a health condition necessitates a comprehensive approach to management and prevention, focusing on dietary changes, increased physical activity, and sometimes medical interventions.
What are its symptoms?
The main symptom of obesity is having a high amount of body fat, especially around the waist. Some other common symptoms and signs of obesity include:
- Excess body fat, especially around the waist
- Back pain
- Fatigue and tiredness
- Heavy sweating
- Difficulty performing physical tasks
- Snoring and breathing problems
- Joint and back pain
- Low confidence and self-esteem
- Feeling isolated
Obesity can also lead to psychological issues like depression that may affect relationships and quality of life. The excess weight puts additional stress on the body, leading to problems like breathlessness, insomnia, and reduced fertility. That said, weight loss diets are important to combat obesity.
