Final answer:
Anorexia Nervosa is characterized by eating very little, Bulimia Nervosa by binge-eating followed by purging, which can lead to an electrolyte imbalance, and Binge Eating Disorder is associated with the risk of developing type 2 diabetes. A distended abdomen in an undernourished child is more indicative of kwashiorkor, which is related to protein deficiency.
Step-by-step explanation:
To match each scenario with the correct eating disorder, let's discuss each condition in the context given:
- Anorexia Nervosa: Individuals with anorexia nervosa typically eat very little food. This is an eating disorder where persons maintain a body weight below average by starvation and/or excessive exercise. With a distorted body image, they often view themselves as overweight when they are not, leading to severe health outcomes like bone loss, organ failure, and even death.
- Bulimia Nervosa: People with bulimia nervosa often develop an electrolyte imbalance due to regular binge-eating episodes followed by purging behaviors such as self-induced vomiting, using laxatives, or excessive exercise. Such recurrent actions can cause severe dehydration and imbalance in electrolytes.
- Binge Eating Disorder: Individuals with binge eating disorder are at risk of developing type 2 diabetes due to compulsive overeating without compensatory purging behaviors, leading to significant weight gain and associated health risks.
If a child exhibits a distended abdomen, it is more likely a sign of kwashiorkor rather than marasmus. Kwashiorkor is typically associated with protein deficiency despite adequate calorie intake, causing edema and an enlarged belly. In contrast, marasmus is caused by severe deficiency in both calories and protein, leading to extreme weight loss and muscle wasting, without the distended abdomen characteristic of kwashiorkor.
