Bulimia is an eating disorder where those affected engage in binge eating followed by purging, and it is not defined by a person's weight or appearance. Both bulimia and anorexia involve fears of weight gain, feelings of low self-esteem, perfectionism, negativity, and depression, as well as potential suicidal tendencies. For those with bulimia, their condition involves cycling through dieting, binge eating, purging, feelings of guilt and anxiety, which can have negative health consequences over time. Treatment aims to break this cycle and improve mental health.
