Doctor's Notes on Food Poisoning Treatment
The term “food poisoning” has been used to refer to a foodborne illness. This can be due to consumption of food that contains a toxin, chemical or infectious agent (such as a bacterium, virus, parasite, or prion). Most commonly, foodborne illnesses are caused by Norovirus or the bacterial types Campylobacter, Clostridium perfringens, and Salmonella.
Symptoms of food poisoning may arise from the gastrointestinal tract or in some cases may be more widespread and involve other body systems. The most common symptoms are
- vomiting,
- watery diarrhea,
- abdominal pain and
- cramping.
Vomiting and diarrhea may cause significant fluid loss, leading to symptoms and signs of dehydration. Abnormalities in electrolyte balance can affect the function of a number of body systems. Other associated symptoms can include
- lethargy,
- rectal bleeding, or
- fever.
