Recovering from Food Poisoning
Steps you should take after food poisoning

Food poisoning happens from eating food contaminated with toxins or organisms harmful to the body. Common bacteria such as Staphylococcus or E. coli are usually the culprits behind food poisoning. Food poisoning can occur as an outbreak in a group of people who all ate the same contaminated food, or it can occur in only one individual.
Although food poisoning is relatively rare in the United States, it affects between 60 and 80 million people around the world every year and results in approximately 6 to 8 million deaths. Food poisoning tends to occur in situations such as picnics, large gatherings, and school cafeterias where food may be left out for too long or food preparation techniques are not clean enough. Food poisoning often occurs from undercooked meats or dairy products that have sat out too long.
Food poisoning can be caused by Staph Aureus, E. colic, salmonella, shigella, cholera, botulism, mushroom poisoning, listeria, bacillus cereus, fish poisoning, or Yersinia.
The greatest risk for food poisoning is among the young and elderly. A serious medical condition, like kidney disease or diabetes, a weakened immune system, can also put you at higher risk. Also, if you could be at higher risk for food poisoning when you travel outside of the U.S. to areas where there is more exposure to organisms that cause food poisoning. Pregnant and breastfeeding women should be careful, especially when traveling.
Symptoms of food poisoning
The most common types of food poisoning symptoms usually start within 2 to 6 hours of eating the contaminated food. Depending on the toxin or organism responsible for the food poisoning, that time may be longer (even a number of days) or shorter. Possible symptoms include nausea and vomiting, abdominal cramps, bloody diarrhea, fever, weakness, and headache. Botulism is a very serious form of food poisoning that can be fatal.

Testing for food poisoning
Your doctor will examine you for signs and symptoms of food poisoning, such as stomach problems and dehydration. Your doctor will also ask about foods you have eaten recently. Tests of your vomit, blood, stool, and any leftover food may identify the cause of your illness.

Treatment   
People suffering from food poisoning usually recover from the most common types of food poisoning within a couple of days. The main thing is to avoid dehydration by drinking plenty of non-dairy non-caffeinated beverages to replace fluids lost by vomiting and diarrhea. You may need intravenous fluids if you have diarrhea and you can’t drink fluids due to nausea and vomiting.
Other complications include respiratory distress, which is brought about by botulism, kidney problems, bleeding disorders, nervous system disorders, and even death. Keep in mind that these complications are very rare and do not occur in the majority of people who suffer food poisoning.
You can prevent food poisoning by washing hands after going to the bathroom, avoiding shellfish, and avoiding foods that have sat out for too long.
