Poverty is both a cause and a result of hunger. Poor households cannot afford nutritious food or the resources to produce it (seeds, fertilizer, land). Because hunger reduces physical and cognitive capacity, productivity drops, keeping the person in poverty.
Chronic hunger, also known as undernourishment, is fundamentally a condition of dietary energy deficiency that persists over years, not days. An individual suffering from chronic hunger consistently consumes fewer calories than their body requires to maintain a healthy, active life. This is not merely "feeling hungry" before a meal; it is a state of biological desperation where the body begins to conserve energy by shutting down non-essential functions. The physical consequences are devastating and cumulative. In children, it manifests as —an irreversible condition where impaired growth leads to shorter height, reduced cognitive capacity, and weakened immune systems. In adults, it results in chronic fatigue, muscle wasting, and a heightened susceptibility to disease. Unlike the dramatic weight loss of famine, a chronically hungry person might not look emaciated; they might simply look smaller, tired, and withdrawn. This invisibility is the cruelest feature of the crisis, allowing it to fester unnoticed in rural villages, sprawling slums, and even within marginalized communities in wealthy nations. chronic hunger
