A. Multiple sclerosis
B. Anorexia nervosa
C. Bulimia nervosa
D. Systemic sclerosis
Correct Answer: B. Anorexia nervosa
All of the clinical signs and symptoms point to a condition of anorexia nervosa. The key feature of anorexia nervosa is self-imposed starvation, resulting from a distorted body image and an intense, irrational fear of gaining weight, even when the patient is emaciated. Anorexia nervosa may include refusal to eat accompanied by compulsive exercising, self-induced vomiting, or laxative or diuretic abuse.
Option A: Multiple sclerosis (MS) is a demyelinating disease in which the insulating covers of the nerve cells in the brain and spinal cord are damaged.
Option C: On the other hand, bulimia nervosa features binge eating followed by a feeling of guilt, humiliation, and self-deprecation. These feelings cause the patient to engage in self-induced vomiting, use of laxatives, or diuretics.
Option D: Systemic sclerosis or systemic scleroderma is an autoimmune disease of the connective tissue.
