Food Poisoning Symptoms

Food poisoning symptoms are typically caused by bacterial or viral infection. When you ingest food that is contaminated with dangerous germ, your body may react within hours or days of ingestion. You can often treat simple cases of food poisoning at home, while more serious cases may require hospitalization and medical treatment.

Although not all food poisoning results in symptoms, many types do. The severity of these symptoms can vary depending on your age and overall health, the type of bacteria or virus involved, and how much-contaminated food you ate. The following are common symptoms of food poisoning.

Upset stomach

Stomach cramps

Nausea

Diarrhea

Vomiting

Fever

When to see a doctor

Symptoms of food poisoning do not always indicate a serious problem since most cases will resolve with no medical intervention. However, seek medical treatment if you have these symptoms:

Bloody Diarrhea

High Fever

(temperature over 102°F, measured in your mouth)

Dehydration

Little or no urination, a very dry mouth and throat, or feeling dizzy when standing up

Frequent Vomiting

that prevents keeping liquids down (which can lead to dehydration)

Diarrhea

Diarrhea that lasts more than 3 days

Severe Malaise

If you feel unusually unwell, seek medical attention.

Legal Assistance

If you are a victim of food poisoning caused by someone else’s negligence you may be entitled to financial compensation through a food poisoning lawsuit.
