Anorexia is a serious and potentially life-threatening eating disorder that is characterized by an obsession with weight loss and an aversion to food. It is estimated that anorexia affects up to 1% of the population, and it is estimated to affect more women than men.
The exact age at which anorexia begins is difficult to determine, as it can manifest in different ways and at different ages. In general, anorexia can begin in adolescence, though it can start at any age. The average age of onset is around 15 or 16 years old, but it can start as early as age 11 or 12. It is important to note that anorexia can also manifest in adulthood, and has been known to occur in people in their 30s, 40s, and beyond.
The risk factors for developing anorexia are varied and can include biological, psychological, and environmental factors. Biological risk factors may include genetics, hormonal imbalances, and metabolic changes. Psychological risk factors can include low self-esteem, body dissatisfaction, and a need for control. Environmental risk factors may include exposure to media images of thinness, pressure to be thin, and a family history of an eating disorder.
It is important to note that anorexia is a complex disorder and that the age of onset can vary greatly from person to person. If you are concerned that you or someone you know might be suffering from anorexia, it is important to seek professional help.
