Definition & Meaning of "undernourishment"

What is "undernourishment"?

Undernourishment occurs when a person does not get enough essential nutrients from their diet to stay healthy and keep their body working properly. It can lead to various health problems, including weight loss, weakness, not growing properly in children, and weaker immune system. Undernourishment can happen because of not eating enough, not having a good diet, or having conditions that make it hard for the body to use nutrients, like certain medical problems or being very poor. Helping with undernourishment often means making sure people have enough good food to eat, teaching them about eating healthy, and giving extra nutrients when needed to help them stay healthy.
