I am experiencing constipation and passing gas. I drink a lot of water and take fibre daily. What can make me pass stools the first thing in morning?

Constipation. If, despite good fluid and fiber intake, you have no significant urge to have a bowel movement I recommend taking daily senokotS which is a gentle bowel stimulant containing a stool softener also. Try to avoid chronic laxative use if possible. If you have urge but can't move your bowels, insert a dulcolax rectal suppository or fleets enema as needed.
