The correct answer is A.
Bulimia nervosa is associated with bingeing and purging which means that people with this eating disorder will eat and eat and eat until they feel sick and then purge what they have eaten by vomiting up their food. In this way they are not actually allowing any of the food they have eaten to digest in their stomach and put on any weight
Specialists can arrange either a blood or pee test to decide whether a man has an issue with their starch digestion. While both tests can distinguish issues with digestion, comes about have indicated blood testing to be more exact.
The sympathetic nervous system causes a speeding up of bodily functions (i.e. heart & respiratory rates) & protects the core by shunting blood from the extremities to the core !! hope this helps hun. have a great day ☺️
