Hi, chronic contipation should be dealt with first of all as it will give you a lot of releive, take enough amount of roughage in your diet, can take isabgul 2 tsp in water or juice once daily, drink 1o glass of water daily, do some exercise daily, do 500 meter walk after each meal, you can take dulcolax tab at night for few days in the begining.try to avoid simethicone as it does not prevent formation of gass but just facilitate its clearance , rather you should avoid all spicy foods, fried , pickles, excess of coffee. keep on taking prilosec for few weeks and you can withdraw it when your constipation and reflux both are gone completely.actually you need to change your life style and food content to avoid these condition in future. thanks for consulting HCM.
