You will usually recover from the most common types of food poisoning within a couple of days. The goal is to make you feel better and avoid dehydration. Drink any fluid (except milk or caffeinated beverages) to replace fluids lost by diarrhea and vomiting. Children should be given an electrolyte sold in drugstores. Don't eat solid foods until the diarrhea has passed, and avoid dairy, which can worsen diarrhea.

If you have diarrhea and are unable to drink fluids (for example, due to nausea or vomiting), you may need medical attention and intravenous fluids. This is especially true for young children. If you take diuretics, you need to manage diarrhea carefully. Talk to your doctor -- you may need to stop taking the diuretic while you have the diarrhea. Medications should NEVER be stopped or changed without discussing with your doctor and getting specific instructions.

For the most common causes of food poisoning, your doctor would NOT prescribe antibiotics. Antibiotics can actually prolong diarrhea and keep the organism in your body longer.

If you have eaten toxins from mushrooms or shellfish, you will need to be seen right away. The emergency room doctor will take steps to empty out your stomach and remove the toxin.

Dehydration is the most common complication. This can occur from any of the causes of food poisoning.

Less common but much more serious complications include:

• Respiratory distress, including the need for support on a breathing machine (botulism)
• Kidney problems (Shigella, E. coli)
• Bleeding disorders (E. coli and others)
• Arthritis (Yersinia and Salmonella)
• Nervous system disorders (Botulism, Campylobacter)
• Pericarditis (Salmonella)
• Death -- 50% of people with mushroom or certain fish poisonings (like puffer fish) die and 10% with botulism
