Obesity is a medical condition in which excess body fat accumulates to the extent that it may have a negative effect on health. It is defined as having a body mass index (BMI) of 30 or higher. Obesity is a complex and multifactorial disease that is caused by a combination of genetic,environmental, and behavioural factors.

  • Poor diet : Consuming a diet high in calories, especially from processed and high-fat foods, can contribute to weight gain and obesity.
  • Lack of physical activity : Physical inactivity is a major contributing factor to obesity. People who are physically inactive are more likely to gain weight and develop obesity.
  • Genetics : Obesity can run in families, and certain genetic factors can make people more susceptible to weight gain.
  • Environmental factors : Factors such as the availability of unhealthy food options, lack of safe places to exercise, and long work hours can contribute to obesity.
