When food or beverages that have been infected with certain bacteria, parasites or viruses are consumed the result is food poisoning. The infectious agent can cause a host of side effects including diarrhea, vomiting, abdominal pain and even a fever. Most food poisoning cases resolve within about 48 hours, suggests the Mayo Clinic. Some bacteria or parasites may require medication for treatment, but most can be resolved at home. The infection itself may just need to run its course, but there are ways to relieve the discomfort associated with food poisoning.
Rest
Food-borne illness is like any other sickness and requires plenty of rest to recuperate. Vomiting and diarrhea can cause dehydration, so it is important that a person take it easy to allow the body time to recover. In addition to resting the body it is important to rest the stomach. This means avoiding foods or beverages for a few hours until the vomiting or diarrhea have slowed. Drinking or eating harsh foods, like caffeine or citrus, can only exacerbate the symptoms. With vomiting it is best to wait a full hour after it has stopped before attempting to eat anything. Water or ice chips are acceptable during the illness, says the Mayo Clinic.
Rehydration
Once several hours have passed, rehydrate the body to prevent serious dehydration. Drink clear broths, beverages or non-caffeinated sports drinks. Gulping down liquids is not recommended as the body may not be fully recovered from the infection. Instead, take small and frequent sips of the fluids. Continue drinking plenty of fluids until your urine is clear or pale.
Eating
Several hours after diarrhea has slowed or vomiting has stopped it is safe to begin introducing bland foods back into the diet. Begin with bananas, rice, applesauce and toast. These foods are easy to digest and can help firm up stools, reducing diarrhea.
Avoid Medications
Medications should only be used if recommended by a medical professional, as the symptoms of food poisoning are just the body's way of removing the toxin. The Centers for Disease Control and Prevention points out that some over-the-counter medications aimed at treating diarrhea may be used, but it is not recommended for cases where diarrhea is severe or bloody. These medications may not have a positive effect on certain infectious agents. Avoiding anti-diarrheal medicines is probably best unless an official diagnosis has been obtain from a medical professional. Any over-the-counter pain relievers should also be avoided, even for fever reducing, because the ingredients can be harsh on the stomach. Any form of anti-bloat, anti-gas or antacid medication can have the same effect. Prescription medications may be given by a doctor for specific illnesses.
