Obesity

Obesity is a medical condition, occasionally referred to as a disease,[8][[9][10] in which excess body fat has built up to the point that it may be harmful to health. When a person's body mass index (BMI), which is calculated by dividing their weight by height squared, exceeds 30, they are considered obese; between 25 and 30 kg/m2 is considered overweight. [1] Lower numbers are used in several East Asian nations for calculating obesity. Obesity is a significant contributor to disability and is linked to a number of illnesses and ailments, including osteoarthritis, type 2 diabetes, obstructive sleep apnea, some forms of cancer, and cardiovascular diseases. Individual, social, and environmental factors all contribute to obesity. Diet, physical activity, mechanisation, urbanisation, genetic vulnerability, drugs, mental illnesses, economic policies, endocrine abnormalities, and exposure to certain substances are some of the recognised factors.
