Malnutrition refers to deficiencies, excesses, or imbalances in a person's intake of energy and/or nutrients. It encompasses both undernutrition and overnutrition, affecting individuals across all age groups. Undernutrition includes wasting, stunting, underweight, and deficiencies in vitamins and minerals. Overnutrition can lead to overweight, obesity, and diet-related non-communicable diseases such as heart disease, diabetes, and cancer.
