Final answer:
The correct answer is option Charlize has bulimia nervosa.
Step-by-step explanation:
Given Charlize's behavior of eating large amounts of food and then forcing herself to vomit, her doctor would most likely suspect that she is suffering from bulimia nervosa. This eating disorder is characterized by recurrent episodes of binge eating followed by attempts to purge the body of the food consumed to prevent weight gain. Purging can include self-induced vomiting, the use of laxatives, diuretics, enemas, or excessive exercising.
People with bulimia nervosa may present with normal weight, but they can still have serious health implications such as electrolyte imbalances and irregular heartbeats, both of which can lead to more severe health problems.
