I am 52 years old suffering from constipation. I am diabetic for the last 2 years and I have hypothyroid. I was taking metformin 250 mg for sugar complaint and thyronorm 12.5 mg for hypothyroid. While the sugar and thyroid are in good control, I have recently started struggling from severe constipation and corresponding problem gas. For this, my doctor has advised to consume cetapin xr 500 in place of metformin 250 mg. I have been taking this tablet for the last 20 days. My doctor also prescribed pre/pro (daily 2 tables for 15 days). Now, after consuming pre/pro for 15 days, I feel a little better with regard to gas problem whereas the constipation problem still persists. Of course, I have been struggling with this since childhood. But, it has been severe these days. Kindly give a longstanding solution to my problem as I am not in a position to face this.
