Hunger is the body's way of telling a person that it needs food. After eating enough food, hunger usually temporarily goes away.
Sometimes, however, a person may feel as though they are hungry all the time. They may find that they do not feel full after eating, or that the desire to eat continues throughout the day.
A person may be able to reduce their hunger by making dietary or lifestyle changes. However, constant hunger can also be a sign of certain medical conditions that may need treatment.
