Food poisoning is an unpleasant experience that can disrupt your life. Understanding the duration, symptoms, and treatment options is crucial for a speedy recovery. This guide provides comprehensive information on food poisoning, covering everything from recognizing the symptoms to knowing when to seek urgent medical attention.
The symptoms of food poisoning can vary depending on the type of contamination, but commonly include:
- Nausea and vomiting
- Diarrhea
- Stomach cramps and abdominal pain
- Fever
- General feeling of malaise or being unwell
The onset of these symptoms usually occurs within a few hours to a few days after consuming contaminated food. However, in some instances, symptoms might not appear for several weeks.
Treating Food Poisoning at Home
In most cases, food poisoning can be effectively managed at home. The typical duration of symptoms is less than a week. Focus on preventing dehydration by consuming plenty of fluids.
Here’s what you should do:
- Rest: Stay home and prioritize rest to allow your body to recover.
- Hydrate: Drink plenty of fluids like water or diluted squash. Take small sips if you feel nauseous.
- Infant Feeding: Continue breastfeeding or bottle-feeding your baby. If vomiting occurs, offer smaller, more frequent feeds. For formula-fed babies or those on solid foods, provide small sips of water between feeds.
- Eating: Eat when you feel able. Avoid fatty or spicy foods initially.
- Pain Relief: If you experience discomfort, take paracetamol, following the dosage instructions on the leaflet.
What you should avoid:
- Sugary Drinks: Avoid fruit juice and fizzy drinks as they can worsen diarrhea.
- Diluted Formula: Do not dilute baby formula; use it at its usual strength.
- Anti-Diarrheal Medication for Children: Do not give anti-diarrheal medications to children under 12.
- Aspirin for Children: Do not give aspirin to children under 16.
When to Seek Advice From a Pharmacist
A pharmacist can provide valuable advice and recommend appropriate treatments. Consult a pharmacist if:
- You or your child (over 5 years) exhibit signs of dehydration, such as dark urine, strong-smelling urine, or reduced urination frequency.
- You are an elderly individual, have a compromised immune system, or have underlying health conditions that increase the risk of dehydration.
- You need temporary relief from diarrhea.
A pharmacist may recommend:
- Oral Rehydration Solutions: These powders are mixed with water to create a rehydrating drink.
- Anti-Diarrheal Medication: Medications like loperamide can provide temporary relief from diarrhea (not suitable for children under 12).

What Causes Food Poisoning?
Food poisoning results from consuming food contaminated with harmful germs. Contamination can occur if food is:
- Not cooked or reheated thoroughly.
- Not stored properly (e.g., not frozen or chilled).
- Left at room temperature for extended periods.
- Handled by someone who is ill or hasn’t washed their hands.
- Eaten after its “use by” date.
Any type of food can potentially cause food poisoning.
Common infections that lead to food poisoning:
- Campylobacter bacteria (the most frequent cause in the UK)
- Salmonella bacteria
- E. coli bacteria
- Norovirus (vomiting bug)
Preventing food poisoning involves proper food handling and preparation practices. Consult resources from reputable organizations like the Food Standards Agency for detailed guidelines on food hygiene and safety. Knowing “how long does food poisoning last” is important, but preventing it is even better.
