Explanation: people with this kind of disorder will always eat a large meal in front of people but will take everything out by inducing vomit after they have eaten. The brittle nails are caused by constant inducing vomit , they faint and light headed because they don't have sufficient nutrients needed in their body as they always take the good out after eating.
Anorexia nervosa is characterized by a highly complex and alarming vitamin, mineral and nutritional deficit.
We deduce that it is this pathology by which the nails become brittle since the keratin is synthesized in a defective way. The presence of hair on the body, which some call the "woolly" body, is a mechanism in the body to protect body temperature and maintain it at times when there is not enough energy to balance it.
on the other hand also if it was bulimia nervosa or bulimia something characteristic of this pathology that in this case is not named, therefore it does not follow that the patient manifests it as a sign is the presence of dental erosion, yellowed fingertips, brittle nails and yellow but due to the induction of constant vomiting and gastric reflux. However this does not happen, that is why this option is recommended as the correct one.
