Final answer:
Anorexia Nervosa leads to drastic weight loss, amenorrhea, bone mass loss, heart weakness, low blood pressure, and a distorted self-perception of body weight.
Step-by-step explanation:
The physical changes that accompany Anorexia Nervosa include severe weight loss due to malnutrition, leading to a significantly low body weight. It often causes amenorrhea (the cessation of menstrual periods) in females, loss of bone mass, weakening of the heart, low heart rate and blood pressure, and can result in weakness, dizziness, fainting, and even heart failure in extreme cases. In addition to these changes, anorexia nervosa is associated with a distorted body image, where individuals perceive themselves as overweight despite being underweight.
