Took three ducolax pills they worked but now i feel bloated how can i relieve this also is it possible that eating too much oatmeal constipated me?

Unlikely: In regards to the bloating the best thing to help is ambulation. Walking will help the intestines pass the gas that has built up. I would avoid any additional medications for the bloating at this point. It is unlikely for the oatmeal to cause constipation unless you had an extremely unusual amount. If symptoms continue you should f/u with your md.
