Abstract
The medical professional continues to see a lot of adolescents with
gastrointestinal illnesses, which have a big emotional and financial toll. One cannot
overstate how crucial it is to identify gastrointestinal disorders correctly. Diseases like
Lactose intolerance and Celiac disease cause nutrition deficiency among many
adolescents. Gastrointestinal disorders are illnesses that comprise a variety of chronic
or recurrent symptoms that cannot be fully explained by structural or biochemical
research at this time. One cannot overstate the significance of correctly diagnosing
gastrointestinal diseases in children. Children and their parents need to be aware that
their diagnosis is not only psychological but also medical. The physiological and
psychological factors that contribute to symptom manifestation must be considered
throughout management and therapy. The chapter focuses on illnesses that affect
adolescents, including appendicitis and ailments of the colon, rectum, small and large
intestines, and stomach.
