Generally Feeling Sick

Food poisoning is characterized by a loss of appetite as well as other signs of disease, such as exhaustion. As your immune system fights the infection that has infiltrated your body, this happens.

Your body responds by releasing chemical messengers known as cytokines. Cytokines have a variety of functions, one of which is to regulate your body's immune response to infection. They do this by directing your immune cells on where to go and what to do. Cytokines convey messages to the brain and cause many of the symptoms associated with sicknesses, such as lack of appetite, fatigue, and aches and pains, in addition to helping your body fight an infection like food poisoning. As a result of this group of symptoms, you may withdraw from social activities, rest, and stop eating, which is referred to as "sickness behavior." Sickness behavior indicates that your body is diverting its attention away from other body processes, such as digestion, in order to concentrate on battling an infection.
