The only medication I've been taking for the ulcer is Prilosec. I've been taking Exforge 10mg for high blood pressure for 4 years and have not had a problem with constipation. The constipation and soft stools started before the Ulcer diagnoses and Prilosec. I recently had a CT scan and was told I have spots on my liver. I'm wondering if this could be a cause.
Isis, are you taking any medication for the condition? If so, it's possible the medication may be causing the problems. Many GI medications, like others taken for a variety of conditions, can cause alterations in bowel habits.
The ulcer is probably bleeding causing the dark stool, and if I were you I'd contact your GI and address this new symptom with him. I would think the ulcer would be healed enough by now to not be bleeding, so he needs to know about this. Take care..
