What causes grey coloured stool while on Nexium for treating GERD?
Question: Hello.
I was started on Nexium 20mg 10 days ago after an EGD. My discharge diagnosis was erosive gastritis, intermittent GE patency w/o esophagitis, gastric polyps and r/o celiac. My celiac panel indicates a strong diagnosis however my provider is waiting for biopsy results for confirmation. The last 6 days my stool has been changing color. This morning it is all grey and it appears very different in texture (semi formed) and not smooth. I have taken over the counter antacids during the past week. None yesterday and only 2 chewables the day prior. The most i consumed in one day was 4 chewables. That was three days ago. I have been following a gluten free diet for 4 weeks now and 10 days of GERD diet modification. I not sure if I should be concerned about this or if it is normal . Also with intermittent abdominal pain average of 2/10 on Thursday 7/10 for a few minutes.

Detailed Answer:
Hi there,
Thanks for posting in HCM.
I am Dr.Barani and I am pleased to assist you.
You have acid peptic disease, gastric polyps and gluten sensitivity.
Celiac can cause altered bowel movements. But since you have been on gluten free diet for more than 4 weeks now, your symptoms cannot be attributed to celiac disease.
You were started on Nexium 10 days ago and these symptoms started 6 days ago. Nexium is known to alter the gut flora and cause change in bowel movements. So this could be the probable cause.
Continue taking Nexium.
For relief from change in bowel habits, take probiotics.
Let me know if you have any more questions.
Regards,
Dr.Barani
