A 19-year old female is being hospitalized with a BMI of 16. For over a year, she has been dieting and has become more withdrawn from friends and family. She continues to perform well in college classes. An ECG showed bradycardia and her temperature is 36C. Physical findings in the patient with Anorexia Nervosa is likely include:

A. Tachycardia, increased BP: Patients with anorexia nervosa more commonly present with bradycardia and hypotension due to malnutrition, decreased cardiac muscle mass, and autonomic changes. Tachycardia and hypertension are not typical findings. B. Amenorrhea: Amenorrhea is a common physical manifestation of anorexia nervosa in females. It results from hypothalamic-pituitary-gonadal axis suppression due to low body weight, nutritional deficiencies, and energy imbalance. Menstrual irregularities often precede other complications. C. Esophageal tears: Esophageal tears are more commonly associated with repeated vomiting in bulimia nervosa, particularly after forceful purging episodes, rather than restrictive anorexia nervosa without purging. D. Increase in bone density: Anorexia nervosa leads to decreased bone density (osteopenia or osteoporosis) due to low estrogen, poor nutrition, and impaired bone metabolism. Bone density loss increases fracture risk.
