Food Poisoning Recovery: What to Eat and 6 Signs to Go to Hospital
The worst of food poisoning is usually over within a day. What almost nobody tells you is what day two, three and four actually look like, and when a symptom that seemed to be improving suddenly means you need to stop waiting it out.
Before you start
- Most food poisoning resolves within 24 to 48 hours with fluids and rest
- ORS is the priority throughout, not just on day one
- Reintroduce food gradually once vomiting has stopped, starting bland and light
- 6 signs mean hospital, not home care, listed below

Where this picks up
Our Food Poisoning: The First 24 Hours and the Red Flags article covers the acute stage in detail. This one is about what comes after: the recovery timeline over the following days, what to actually eat as your appetite returns, and the specific hospital signs worth knowing by heart rather than looking up while you are unwell.
A realistic recovery timeline
| Day | What is typical |
|---|---|
| Day 1 | Vomiting and or diarrhoea, often the worst symptoms; fluids and rest are the priority |
| Day 2 | Vomiting usually eases; loose stools may continue; appetite starts to return cautiously |
| Day 3 to 4 | Gradual return to normal food; some lingering looseness or mild cramping is common |
| Day 5 onward | Most people feel back to normal; symptoms lasting well beyond this need medical review |
These are typical ranges, not guarantees; some people recover faster, some slower, and children, older adults and anyone with an existing health condition should be watched a little more closely throughout.
Fluids, throughout, not just at the start
Keep taking ORS or a home salt-sugar solution through the whole recovery period, not only on the first bad day. Our Homemade ORS Recipe has the exact ratios. Small, frequent sips work better than large amounts at once, especially while nausea is still present. Plain water alone does not replace the salts lost through vomiting and diarrhoea, which is why ORS remains the better choice throughout, not just for the first hours.
What to eat, and when
- While vomiting is active: nothing by mouth except small, frequent sips of ORS or plain water, a spoonful every 10 to 15 minutes.
- Once vomiting has stopped for a few hours: try plain, dry foods, such as toast, plain rice, or a banana, in small amounts.
- Day 2 to 3: add boiled potato, plain khichdi, or a simple daal without heavy spice or oil, in modest portions.
- Day 3 to 4: gradually return to your normal diet as appetite and stool consistency improve, avoiding very spicy, fried or fatty food for a few more days.
Yoghurt with live cultures is often tolerated well once vomiting has settled and is a reasonable addition during recovery, though it is a comfort food choice rather than a treatment. Avoid caffeine, alcohol and very sugary drinks until your stools are back to normal, since all three can aggravate a still-sensitive gut.
Rice water, khichdi, and diluted daal have long been the household default for anyone recovering from a stomach upset, valued as easy to digest and gentle on a settling gut. This matches reasonably well with general dietary advice for recovery: bland, low-fat, easy-to-digest food in small amounts, building up gradually as tolerance improves.
Lingering symptoms that are usually still normal
Mild fatigue, a slightly reduced appetite, and occasional loose stool for a few days after the main illness has passed are common and do not necessarily mean anything is wrong. Some people develop a temporary difficulty digesting dairy for a week or two after a significant gut infection, which usually resolves on its own; if milk or yoghurt seems to worsen things, simply reduce it for a week and reintroduce gradually.
Try this
Keep a small note of what you ate and how you felt afterward for the first few days back on food. It makes it much easier to tell a genuine intolerance from ordinary caution if something seems to disagree with you.
The six signs that mean hospital, not home care
- Signs of significant dehydration: very little or no urine for 8 hours, dizziness on standing, a dry mouth and sunken eyes.
- Blood in vomit or stool, or black, tarry stools.
- A fever over 39°C that does not settle, or any fever in someone with a weakened immune system.
- Severe abdominal pain that is constant and worsening rather than crampy and coming in waves.
- Confusion, extreme drowsiness, or fainting.
- Symptoms lasting more than 3 to 5 days without any improvement at all.
Anyone in a high-risk group, including infants, pregnant women, older adults, and people with diabetes, kidney disease or a weakened immune system, should have a lower threshold for seeking medical care rather than waiting through the full home-care timeline. Do not take anti-diarrhoeal medicine without medical advice if there is blood in the stool or a high fever, since slowing the gut down in some infections can make things worse rather than better. Do not use leftover antibiotics from a previous illness; most food poisoning is not helped by antibiotics and taking them without a diagnosis is not safe.
Getting back to normal life
Wait until you have been symptom-free for at least 48 hours before returning to preparing food for others, since you may remain infectious for a period after symptoms resolve, particularly with certain bacterial causes. Ordinary handwashing after using the toilet and before handling food remains the single most effective way to avoid passing it on to family members during your recovery.
Preventing the next episode
Most household food poisoning traces back to a handful of repeat causes: meat or poultry left out too long before or after cooking, reheated rice that sat at room temperature, and food handled after a bathroom visit without proper handwashing. Keeping cooked food refrigerated within two hours, reheating leftovers until steaming hot rather than just warm, and washing hands with soap for a full 20 seconds before handling food cut most of the everyday risk without needing anything more elaborate.
Returning to exercise or heavier physical work is worth pacing gently too. A day or two of feeling capable but slightly under-recovered is normal; pushing straight back into strenuous activity before fluids and electrolytes are fully replaced can leave you dizzy or unusually tired, which is your body’s fair warning to slow down a little longer.
Special note for travellers and large households
If several household members fall ill around the same time after a shared meal, this points more strongly toward a food-borne cause than a passing virus, and it is worth noting exactly what everyone ate and when symptoms started for each person, since that timeline is genuinely useful information if a doctor needs to be involved for anyone who does not improve as expected. Discard any leftovers from the suspected meal rather than risking a repeat episode, and clean the kitchen surfaces and utensils used before cooking again.
How long is food poisoning usually contagious?
This varies by cause, but avoiding food preparation for others for at least 48 hours after symptoms stop is a reasonable general precaution.
Is it normal to feel weak for days after?
Mild tiredness for a few days as your body recovers and rehydrates is common and not usually a cause for concern on its own.
Can I go back to spicy food right away?
It is better to wait a few more days after your stools return to normal, since spice and heavy oil can unsettle a still-recovering gut.
Should I take probiotics during recovery?
Plain yoghurt with live cultures is a reasonable food-based option; specific probiotic supplements are a personal choice best discussed with a pharmacist or doctor if you are considering one.
When can children go back to school after food poisoning?
Generally once they have been free of vomiting and diarrhoea for 48 hours, though school-specific policies can vary.
