Nutritional Deficiencies in Children
Overview
Nutritional deficiencies occur when a child does not receive enough nutrients needed for healthy growth, development, and normal body function. These deficiencies may affect physical growth, immunity, energy levels, learning, development, and recovery from illness.
Some children may develop nutritional deficiencies because of poor dietary intake, feeding difficulties, recurrent illness, digestive problems, or increased nutritional needs during growth. Symptoms may develop gradually and can sometimes be difficult to notice early.
The focus is on identifying nutritional concerns early, supporting healthy growth and development, and improving long-term health through assessment, monitoring, and nutritional support.
Symptoms
Children with nutritional deficiencies may experience symptoms that affect growth, development, immunity, energy, or physical wellbeing. Symptoms may include:
- Poor weight gain or growth
- Tiredness or weakness
- Reduced appetite

Some children may also experience feeding difficulties or behavioural changes linked to poor nutrition.
