What causes stomach pain after having outside food?

Hello,

Welcome to icliniq.com.

I can understand you are worried about your health. I know you got digestive system problems based on the possible food poisoning after you ate what looks like a contaminated food from a local food chain. It is a widespread issue, and many people whole eat from outside get food poisoning if the food was contaminated.

You are taking the very best step of hydrating yourself. I would advise taking plenty of fluids (as you are already taking) plus ORS (oral rehydration solution) or Pedialyte to rehydrate yourself. Keep an eye on the symptoms, and if they are severe enough, you should rush to a healthcare provider or a hospital. The time you need to seek medical attention would include any one or many of the following five severe symptoms,

1. High fevers (over 102 degrees of Fahrenheit, when measured with an oral thermometer).

2. Blood starts coming in stools.

3. You take fluids, and they cannot go down the stomach due to severe and frequent vomiting. No liquid is staying inside the gastrointestinal tract, and you may get dehydrated in that way.

4. Symptoms of dehydration that you can feel by yourself, e.g., dizziness on standing up, decreased urine volume and dark colored urine, very dry mouth and throat, and no sweating.

5. Diarrhea lasting more than 72 hours from the time of its onset after the food poisoning.

You got this stomach cramps (pain) in a timeframe of 30 minutes to an hour after eating the food. This refers to the possibility of food poisoning caused by a germ named Staphylococcus aureus (commonly abbreviated as staph). And this type of bacteria affects the foods not cooked adequately after handling. These foods can include but not limited to sliced meats, puddings, sandwiches, pastries. I hope it helps. Please feel free to ask more if you need further assistance.
