Famine

If hunger decreases, this can lead to excesses in eating behavior and the development of obesity. On the other hand, if the satiety center does not function properly, it can lead to malnutrition and exhaustion of the body.

Hunger is a physiological phenomenon that is common to all animals and humans. It expresses the body’s need for food and directs animals and humans to actively search for food and consume it. It has been experimentally established that there is a hunger center and a satiety center in the brain, which play an important role in regulating feelings of hunger and satiety.

The feeling of hunger can manifest itself in the form of various physical symptoms, such as burning, pressure, even pain in the epigastric region (hunger pains), sometimes nausea, dizziness, and headache. The external manifestation of hunger is a persistent search for food, which may be associated with overcoming significant obstacles.

An important role in regulating the state of hunger and satiety is played by the depot of nutrients that are present in the body and are closed much earlier than all the nutrient reserves in the body are used up. This is one of the protective and adaptive mechanisms that protect animals and humans from exhaustion and force them to look for food long before these depots are emptied.

Violations in the relationship between hunger and satiety can lead to obesity or exhaustion of the body. If nutrient depots stop periodically closing, then depletion occurs; if they close too early, even with an excess of nutrients in the body, obesity develops. Regulation of the emptying of nutrient depots is determined by the state of the central nervous and endocrine systems.

The conclusions that can be drawn from all these facts are that the feeling of hunger is an important and necessary physiological phenomenon that regulates the body's need for food and directs animals and humans to search for and consume food. However, disturbances in the regulation of hunger and satiety can lead to serious nutrition and health problems such as obesity or wasting. Therefore, it is important to monitor the condition of your body and properly regulate your diet.

Hunger is a complex socioeconomic and political phenomenon that has serious consequences for the health, safety and well-being of people around the world. Hunger is one of the most severe and widespread problems in the world. Hungry people suffer from malnutrition, which can lead to decreased immunity, anemia, diarrhea, an increase in infectious diseases and even death.

Hunger is associated with poverty and deprivation when there is not enough food. The World Food Program (WFP) estimates that about 690 million people, or 8.5% of the world's population, suffer from occasional or chronic hunger, including children under five years of age. Other estimates suggest that the number of hungry people could be as high as 2.6 billion as of 2019
