Malnutrition refers to deficiencies or excesses in nutrient intake, imbalance of essential nutrients or impaired nutrient utilization.
The double burden of malnutrition consists of both undernutrition and overweight and obesity, as well as diet-related noncommunicable diseases.
Undernutrition manifests in four broad forms: wasting, stunting, underweight, and micronutrient deficiencies.
Wasting is defined as low weight-for-height.
