Food poisoning is a non-medical term that refers to an illness caused by eating contaminated food. The food may be contaminated by an infectious agent (like bacteria or a virus), toxin, or chemical.
The main signs and symptoms of food poisoning include nausea, vomiting, diarrhea, and abdominal pain and cramping. Other associated symptoms can include fatigue, lightheadedness, loss of appetite, indigestion, headache, bloating and weakness. Signs and symptoms of dehydration are common due to the fluid loss through vomiting and diarrhea. In some cases, fever and chills may develop. Most cases of food poisoning go away on their own within a few days.
