Hi and thanks for the query,
Its important you recognize already that its due to a change in diet. The first thing might be try to know whether the symptoms you are experiencing are also experienced by others who ate the same food. This could be important to give an idea on food intoxication. If others are not complaining, that it would be worthwhile somewhat avoiding the particular food type in future.
Depending on whether you are experiencing only
abdominal pain, or is accompanied by diarrheoa or vomoiting the management would be different. If pain is mainly above the navel and moving to the back, this could be indicative of
gastritis, and if present, antacids could give relief. If its only abdominal colics, anti spasmodic drugs could help for now.
In case symptoms persist for two or more days, you might to consult your
primary care physician for reevaluation. For now, antacids and antispasmodics, as advised by your pharmacist could be very useful.
Thanks and best regards,
