Gastrointestinal problems refer to a range of disorders affecting the digestive system, which can lead to discomfort, pain, and various physical symptoms. In the context of eating disorders, such as anorexia nervosa and bulimia nervosa, these issues often arise due to extreme dietary restrictions or compensatory behaviors like purging. Such gastrointestinal disturbances can complicate the health outcomes for individuals suffering from these disorders and impact their recovery processes.
