definition of malnutrition

Malnutrition is a condition that occurs when the body does not receive enough of the nutrients it needs to function properly. It can be caused by an inadequate diet, difficulty absorbing nutrients, or an increased need for nutrients due to illness or other factors. Malnutrition can lead to a range of health problems, including weakness, fatigue, and impaired immune function.

There are two main types of malnutrition: undernutrition, which occurs when the body does not receive enough nutrients, and overnutrition, which occurs when the body receives more nutrients than it needs. Undernutrition can be caused by a lack of food or an insufficient variety of foods, and it can lead to conditions such as malnutrition, anemia, and vitamin and mineral deficiencies. Overnutrition, on the other hand, can be caused by consuming too many calories or an unhealthy balance of nutrients, and it can lead to conditions such as obesity, type 2 diabetes, and heart disease.

Malnutrition can affect people of all ages and can have serious consequences for physical and cognitive development, particularly in children. It is a global health problem that can be prevented or treated through a combination of improved nutrition, education, and access to health services.
