What is Food Poisoning?
Dr. Roberson explains, "Food poisoning is when you get sick from food or drinks contaminated by harmful bacteria, a virus, or parasites. Most commonly, it is caused by bacteria, such as E. coli and clostridium perfringens. When these foreign invaders enter our digestive tract, they release toxins that act like poison. Our body detects this within minutes to hours and responds by doing what it can to rid the digestive tract of these toxins."
How Food Poisoning Happens
According to Dr. Roberson, "Food poisoning most commonly occurs because of food that is ill-prepared. Food can become contaminated really at any point in the preparation process. We often hear of food poisoning related to animal products like chicken. When undercooked, animal meat and eggs can carry harmful bacteria, making the eater quite ill for a short period of time. You can also get food poisoning from other products, including food that has passed its expiration date and fresh fruits and vegetables that are unwashed."
How Long it Takes for Signs of Food Poisoning to Appear
"Most cases of food poisoning show up pretty quickly," says Dr. Roberson. "Some people feel unwell almost immediately after eating, whereas others may develop symptoms within an hour or two. Depending on the type of bacteria, virus, or parasite, it may show up within a few days. Usually, symptoms show up pretty quickly because of the rate food moves through the gut. If you contract a virus such as hepatitis A, symptoms may not appear for a month or more."
Symptoms of Food Poisoning
Dr. Roberson states, "Anyone who has had food poisoning will recall all too well the symptoms that accompany this short-term illness. Nausea, vomiting, diarrhea, abdominal cramping, bloating, and fever are all commonplace in food poisoning. Sometimes, people may develop bloody diarrhea. Again, the body does everything it can to rid itself of the foreign invader, so elimination and fighting back with fever are some of our best defense mechanisms when it comes to food-related illnesses."

Treating Food Poisoning
Dr. Roberson says, "The treatment for food poisoning really depends on the cause and the severity. Most cases of food poisoning go away on their own with plenty of supportive care like hydration and nutrient replacement. Indeed, the body generally wipes out common bacterial infections and can recover within a few days. In more severe cases of food poisoning, people may suffer from dehydration and may need to be under the care of a health provider. Some people may take antibiotics at the onset of symptoms, especially if they know they were infected or it is likely, such as with travel. If you do not have bloody diarrhea, you can take some anti-diarrheal medications like Immodium, but remember diarrhea is your body's way of getting rid of the invader. So, unless diarrhea is making you severely ill or dehydrated, it can be best to let it run its course for a few days."
How to Help Prevent Food Poisoning
"The best way to prevent food poisoning is to eat well-washed, well-cooked food that has been safely prepared," says Dr. Roberson. "Cooking meat to an optimal temperature and checking it with a meat thermometer is essential for eliminating many food-borne illnesses. Also, keeping your prep area clean and washing plates and utensils regularly can help reduce your risk of getting an infection. Aside from how you prepare your food, you can also take probiotics or eat foods rich in probiotics, like yogurt, to keep the numbers of good bacteria higher in your gut."
Complications and Risk Factors of Food Poisoning
According to Dr. Roberson, "The biggest complication of food poisoning is dehydration and systemic illness. Because your body loses a lot of fluid in the process of eliminating infections, it is common to have some degree of dehydration. However, people who become severely dehydrated need medical intervention to help replace fluids and electrolytes. Sometimes, toxins from foreign invaders can leak out of the digestive tract and enter the bloodstream. In these cases, people can become severely ill and may require medical care. Pregnant women need to be especially careful to prevent food poisoning, especially from a bacteria called Listeria, as it can infect the baby and cause miscarriage or stillbirth. Some cases of E. coli may also lead to kidney failure." And to live your healthiest life, don't miss this life-saving advice I'm a Doctor and Here's the #1 Sign You Have Cancer.
