[|Human|] I am from India. Two days back I had pain in upper abdomen . (A week back I got endoscopy done and the report was normal - i.e. no ulcer , no problem.) Also I had vomitting sensation and could eat very little. Hence I went to the doctor. Doctor prescribed me HAPPY-IT. I took the tablet in the evening before food. Pain came down a little but during night the pain was severe and around 1 a.m. I had vomitted all the items that I ate during the day. Yesterday I could eat a little. (I am a migraine sufferer and take rizatriptan ). Today I found my stool to be black. Kindly advise me the caution that I should take. Should I take the HAPPT - it TABLET before food or after food. Thanks. Raghavan
[|AI|]  Hello abdominal pain and passing black tarry stool are the symptoms of gastrointestinal bleeding. And common causes of bleeding are acid peptic diseases, gastric ulcers, gastric erosion and bleeding from lower GI tract. Since you have undergone upper GI ENDOSCOPY (which is normal), it's better to undergo colonoscopy to rule out lower GI bleeding. My advice is to consult gastroenterologist for further management. Get well soon.
