A member asked:

On omeprazole 40mg twice a day i have light coloured stools is this normal?

A doctor has provided 1 answer

Yes: It is reported quite often with PPI but not aware of % of how often happens.Stool changes are common on changes in diet and medications.Also proton pump inhibitors affect the gut microbiome which can affect stool color.
