Brief Answer:
Gas X and Beano tablets half an hour before food

Detailed Answer:
Hello,

You seem to be producing too much gas because of indigestible carbohydraates, more of methane. More methane more foul smelling gas. You should make changes in your diet. You are likely to reduce gas by eating less of the foods that cause gas, such as fruits and vegetables, whole grains, and milk products. Since you already know the culprit foods you should avoid them
You can alternatively take GAS-X and BEANO (alphagalactisidase helps digest veggies) half an hour before each meal. This way the carbohydrates are well digested. Gas X has simethicone which helps in the stomach cramps.
It also makes sense to get an Ultrasound of the abdomen to rule out serious problems causing similar symptoms.
All the best, if you do not have any more queries please close our discussion.
