What is the reason for severe malnutrition in a 5-year-old boy?

Patient's question:

Medical history and treatment outcomes: None
Expected help: Test results
Age: 5 years, Height: 99 cm, Weight: 13.8 kg
The doctor said the child has severe malnutrition. What should I do? Should I go to the hospital for treatment?
Mother's height: 146 cm, Father's height: 172 cm
Is it possible that my baby inherited his short stature from his mother?

Doctor's answer:

First, go to the hospital for a thorough examination to check if the child has any other diseases. If these factors are ruled out, we don't need to worry too much. The growth and development of the child can be mainly assessed by the child's height and weight. If any issues are found, it is important to correct them promptly, as the child's transformation cannot wait. First, parents should start by examining the child's daily diet: is the protein intake sufficient every day?
