Food Poisoning Signs, Symptoms and How Long Food Poisoning Symptoms Last
Common signs and symptoms of food poisoning (foodborne illnesses) include:
- fever
- diarrhea
- vomiting
- headache
- severe exhaustion
- abdominal cramping
- sometimes blood or pus in your poop stools
However, food poisoning symptoms vary according to the type of bacteria and amount of contaminants you ate. In rare instances, signs may come on as early as a half hour after the contaminated food consumption, but typically they do not develop for several days or weeks.
Signs of viral or parasitic food poisoning illnesses may not appear for several weeks after exposure. They usually last only a day or two, but in some cases can persist as long as a week to 10 days.
For most healthy people, food poisoning is neither long-lasting nor life-threatening. However, they can be severe in the very young, the very old, and people with certain diseases and conditions.
If your symptoms are severe and last a long time, you should see a doctor or get emergency help. This is especially important for those who are most vulnerable, like the elderly and those with weakened immune system.
For mild cases of food poisoning, main treatment is drinking plenty of liquids to replace fluids lost through vomiting and diarrhea in an effort to prevent dehydration.
