Have you ever contracted food poisoning? How long does food poisoning last in your own case in terms of the symptoms you experience? Anyway, food poisoning duration depends on the source of the poisoning, food poisoning onset, and whether it was caused by a micro-organism such as bacteria, virus and fungal organisms or toxic substances.

According to medicinenet.com, the Center for Disease Control and Prevention (CDC) estimates approximately 48 million people become ill from food-related diseases each year resulting in 128,000 hospitalizations, and 3,000 deaths.

According to a Wikipedia statistics, virus-mediated food poisoning cases make up about one-third of all food poisoning cases in developed countries while in the USA, about 50% of all cases are caused by viruses, noroviruses specifically. Hepatitis B virus for instance have a long incubation period of about 2-6weeks.

When you start having the following signs, see your doctor:

  • Abdominal cramping
  • Fainting spell
  • Increase in body temperature
  • Vomiting
  • Bloody stool

How fast you seek for medical help will determine how long food poisoning will last. It may lead to coma if signs of complications are not urgently attended to. Persistent diarrhea for instance may lead to severe dehydration with severe consequences if it lingers for too long.

Seeking urgent medical help will help to determine the duration of food poisoning.
