Hi.
Thanks for your query.
Noted the history and understood your concerns.
Abdominal cramps along with gases can be due to the following reasons in a person of 72:
Intestinal infection.
Aerophagia which in turn can be due to stress or
anxiety or related to consumption of aerated drinks.
Overgrowth of gas producing bacteria.
Intolerance to nuts and such things.
I would advise you the following in such a situation:
Get the
stool test done and if you have intestinal infection, you surely have to get the course of an antibiotic,
metronidazole for which you need a valid prescription.
Stop any foods and beverages that you know of causing gases.
Take Activated
charcoal and probiotics as these might help.
Use boiled and cooled water, eat only homemade fresh foods.
