What are the manifestations of malnutrition in infants?

The manifestations of infant malnutrition are varied and evident, mainly including: 1. Growth retardation: The most significant manifestation is slow growth in height and weight, which may even stagnate or regress, falling significantly below the level of children of the same age. 2. Physical and mental condition: Malnourished infants often show weakness, reduced activity levels, poor mental state, and may exhibit irritability. 3. Weakened immunity: Prone to infections, especially respiratory infections and gastroenteritis. 4. Digestive system problems: Digestive issues such as indigestion, diarrhea, or constipation may occur. 5. Skin and hair: Hair may be sparse, yellowish, and lackluster; skin may be dry and fragile. 6. Other symptoms: Anemia, poor responsiveness, and memory impairment may also be present. If the above symptoms appear, parents should promptly take the infant to see a doctor to ensure timely and effective diagnosis and treatment.
