Golden yellow stool color over past months

Patient: Hello. I am a 30 year old female. I have heartburn and am being treated for anxiety. For the past 6-8 months I’ve had a golden yellow colored stool. I do not have any abdominal pain or other symptoms with the stool. I do worry and the past week I’ve had a nervous feeling in my stomach due to the anxiety. I’ve been taking omeprazole for about 1 year and 2 months. What could cause the stool color change?

Symptoms: Golden yellow colored stool
