Food poisoning can range from very mild symptoms to severe symptoms that could require medical attention. Symptoms can also vary depending on the germ that was ingested along with your food. Food poisoning can come from food or beverages, as long as they are ingested into the stomach. Symptoms are not always immediate and may take hours or days to fully develop. Some of the common symptoms of food poisoning include upset stomach, stomach cramps, fever, diarrhea, nausea and vomiting. If you are experiencing symptoms of diarrhea or vomiting, it is important to drink water to stay as hydrated as possible and avoid further complications. If you are experiencing more serious symptoms such as bloody diarrhea, high fever of 102F or more, unable to keep liquids down with frequent vomiting, indications of dehydration such as feeling dizzy upon standing, dry mouth and throat or little to no urination, or diarrhea that has lasted for more than three days you should seek medical treatment from your doctor.
