What is the Difference Between Food Poisoning and Gastroenteritis?

Food poisoning and gastroenteritis, also known as the "stomach flu," are both illnesses that affect the digestive system and have similar symptoms. However, there are key differences between the two:

1. Causes: Food poisoning is typically caused by consuming contaminated food or water, and it can be caused by bacteria, viruses, or parasites, with bacteria being the most common causative agent. Gastroenteritis, on the other hand, is usually caused by a virus and is spread from person to person.
2. Symptom Onset: Food poisoning symptoms can appear anywhere from a few hours to weeks following exposure to the contaminated food or water, while gastroenteritis symptoms usually develop within 24 to 72 hours of exposure to a virus.
3. Symptom Duration: Food poisoning tends to have a shorter duration than gastroenteritis, with symptoms often resolving more quickly. Gastroenteritis generally lasts for two days, although it can sometimes last longer.
4. Severity: Food poisoning symptoms can be more severe than those of gastroenteritis, and it is estimated that food poisoning is more common than the stomach flu.

Common symptoms of both food poisoning and gastroenteritis include diarrhea, nausea, vomiting, stomach cramps, muscle aches, loss of appetite, and low-grade fever. However, food poisoning may also present with headaches, chills, sweating, and thirst. To determine which illness you may have, it is essential to consult a healthcare professional for a proper diagnosis and treatment plan.
