Hi,
Welcome to health care magic,
If there is diarrhea and bdominal cramps then there will be chances of
electrolyte imbalance in the blood with gastric upset.
It is due to food
poisoning means bacteria containing toxins which irritates our gastrointestinal system.
You should be monitored for her vitals signs like pulse,blood pressure etc.
You can be given plenty of water with lemon juice (added salt),coconut water or WHO oral rehydration solution.
The important thing is to combat diarrhea and for which you would require antiemetic drugs (mostly injectables or oral),
prebiotics and probiotics with antibiotics (
norfloxacin with antiprotozoals like
ornidazole preferred) with other water and electrolyte fluids.
So,it would be advisable that if you go to physician for all routine blood investigation and proper treatment.
Home treatment might help but you actually requires complete course of treatment as I explained.
Thanks and Regards,
