I'm not sure where to even begin...I've had nausea for so long, and no idea what the cause may be. I've gone from 95 pounds to 84 pounds; currently at 87 pounds. I thought perhaps medications, but cannot point to one in particular. I've tried sinus decongestants, but that doesn't stop it either. No vomiting; just nausea and feeling "not well." I thought the Lisinopril might be the cause, but when I stopped it for only 2 days, my BP went too high. My doctor seems to just ignore the issue. I'm wondering what my gastroenterologist would say/do...?
