Light coloured stools

Posted , 3 users are following.


I have been taking 40mg twice a day of Omeprazole for three weeks. For the last few days I have been passing light, pale, clay coloured stools. Has anyone else experienced this? I am getting myself stressed and worried that it could be Pancreatic Cancer.

    Not sure if I would jump to any conclusions like but contact your doctor for sure. PPIs can cause disruptions in the hepato-biliary system which does affect the quality of your stools. 80mg of omeprazole daily for more than 2 weeks seems to be a high dose especially just for reflux/GERD. I assume that your condition may be something more than simple reflux/GERD since you seem to be taking the non-OTC dosage form. Just want to make sure that you are not taking this longer than necessary as many on this board are suffering from chronic exposure to PPIs.

    Sorry to hear you're feeling worried mumofone. Obviously I'm no expert but I'd say the change in your stools is down to the omep. It's given me a whole range of unpleasant side effects since starting it 12 days ago, hence why I have stopped using it. Yesterday I also had loose, pale stools and I mentioned it to a Dr who said it's probably due to a stomach upset. Your digestive system has probably become sluggish due to the change in acid levels. Remember to eat well and take a deep breath and try not to worry. Laura
