Alcohol and anorexia nervosa can interfere with nutrition. Excessive alcohol intake can interfere with calcium balance by increasing PTH production and by inhibiting the enzymes that convert inactive vitamin D to its active form; in addition, alcohol can result in hormonal deficiencies and can increase the tendency for falls. Poor nutritional states, such as in anorexia nervosa, [216] have been strongly associated with bone loss. Nutritional and endocrine factors contribute to bone loss; in particular, low estrogen states, which result from low body weight, result in significant bone loss.
