A mother notices her 5-year-old son struggling to meet his developmental milestones

A mother notices her 5-year-old son struggling to meet his developmental milestones and appears markedly smaller than his peers at school. Recently, he has been suffering from changing bowel habits, unintentional weight loss, and he appears extremely fatigued. His mum has ensured he eats a healthy and balanced diet; however, this has not seemed to help.

On examination, there is no pear-drop breath, work and rate of respiration are normal, adequate hydration is noted; however, he is complaining of abdominal discomfort.
