Identifying Food Poisoning vs. Other Illnesses
It's important to distinguish food poisoning from other conditions:
| Condition | Onset | Symptoms | Duration |
|---|---|---|---|
| Food Poisoning | 2-6 hours after eating (can be up to 72 hours) | Nausea, vomiting, diarrhea, stomach cramps, sometimes fever | Usually 1-3 days |
| Stomach Flu (Gastroenteritis) | 1-3 days after exposure to virus | Similar to food poisoning but often with body aches | 3-7 days |
| Food Allergy | Minutes to 2 hours after eating | Hives, swelling, difficulty breathing, anaphylaxis | Hours (requires immediate treatment) |

Immediate Actions to Take

This is the most important step. Sip small amounts of clear fluids frequently.

Your body needs energy to fight the infection. Avoid strenuous activities.
4. Monitor Symptoms
Keep track of symptom severity and duration. Note any worsening.
5. Isolate if Possible
Some types of food poisoning can be contagious. Practice good hygiene.

❌ Fluids to Avoid
