Hi,
The two possibilities that come to my mind are gastric issues or an infection due to a stomach bug.
In my clinical practice, if a patient comes with similar symptoms, I would treat him/her with a course of probiotics like
Vizylac which contains lactobacilli and a course of
proton pump inhibitors like
Pantoprazole.
Most symptoms are self-limiting and should get better in a day or 2. if not, further evaluation would be necessary.
Other important things to take care of are good rehydration with oral intake of tender coconut water, rice porridge with a pinch of salt, ORS etc. Buttermilk, apples, bread toast are ideal foods to consume at this time.
Avoid spicy, oily, sour foods at this time. Avoid pulses like dal, green gram, potatoes. Avoid tea, coffee, alcohol, carbonated beverages.
If symptoms don't improve, do consult your treating physician for further evaluation and treatment.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Divya Kuttikrishnan, General & Family Physician
