Malnutrition refers to a condition in which a person's body does not receive enough nutrients to function properly. It can result from a lack of essential vitamins, minerals, and other nutrients, or from an inability to properly absorb or utilize them. Malnutrition can occur due to various factors, including inadequate food intake, poor quality of food, or underlying medical conditions that affect nutrient absorption. It can have serious health consequences, leading to weakness, stunted growth, impaired cognitive function, and increased susceptibility to infections. In severe cases, malnutrition can be life-threatening. Malnutrition is particularly common in developing countries and among populations affected by poverty, food insecurity, and conflict.
