It is easy to confuse gastro and food poisoning since both have more or less the same symptoms.

To differentiate them, it is necessary to look at the temporality: that of the appearance of the disorders, as well as their duration.

Case of food poisoning

If, after a meal, at least two people present almost simultaneously symptoms such as vomiting, diarrhea, or nausea, then food poisoning is strongly suspected.

The duration of food poisoning is quite short: it varies from just a few hours to a maximum of two to three days.

Case of gastroenteritis

Gastroenteritis will have more scattered symptoms over time. If they appear more than 24 hours after the “suspicious” meal, then it is very likely that it is gastroenteritis.

The side effects of gastroenteritis are also more persistent than food poisoning. Finally, the presence of fever should tip the scales more towards gastro rather than towards food poisoning.

To begin with, we recommend that you stay at home so as not to pass on your infection, as it can be contagious.

Soften the symptoms

If there is no specific remedy for food poisoning, its inconvenience can however be reduced.

Taking a painkiller – taking care of its dosage and following the advice of your doctor – will relieve any headaches or abdominal and jugular fever should you. In case of medical swallowing, you can also use an anti-diarrhea or an anti-emetic.

Nutrition and hydration in case of food poisoning

It is important to drink in case of food poisoning. The vomiting and diarrhea cause dehydration it is necessary to compensate. Drink “clear” liquids (water, broth, tea, for example) in frequent small sips.

As soon as it seems possible to swallow something solid again, we recommend that you do so, as your digestive system needs to get back to working order to heal faster. You will thus favor light and fractional intakes, which you will gradually increase.

What food to eat after food poisoning?

Depending on your tolerance and preferences, here’s what we recommend you eat – in small amounts to start – after food poisoning:

• lean meat ;

• cooked fish;

• White rice ;

• soup;

• sweet foods or drinks (chocolate, confectionery, fruit juice, etc.);

• spicy or fatty foods;

  1. Intense abdominal pain;
  2. Difficult breathing or swallowing;
