An eating disorder can significantly disrupt daily activities and deteriorate a person's physical and mental health. Common effects include excessive preoccupation with food, weight, and body shape; engaging in unhealthy behaviors like self-induced vomiting, excessive exercise, and abuse of laxatives, diuretics, or diet pills; and experiencing adverse side effects such as yellowish skin, constipation, weakness, and dizziness. Social and emotional well-being can also be impacted, leading to isolation, depression, or anxiety.
