Hunger refers to the discomfort or weakness caused by a lack of food. It can be short-term, such as feeling hungry between meals, or chronic, which occurs when people do not have enough food for an extended period. Chronic hunger affects millions worldwide, often due to poverty, conflict, natural disasters, and inequality in access to food. It can lead to malnutrition, stunted growth, and severe health problems.

In essence, hunger is both a physical sensation and a global issue impacting food security and human well-being.
