[|Human|] Hi, I have been suffering with severe heartburn for which I have had a ultrasound to check my gallbladder (found a few gallstones but not believed to be causing the issue) and am waiting to be referred for an endoscopy next. Last night after a glass of wine (not a regular drinker) my heartburn was extreme causing me to be sick (not unusual). However, my vomit was black which concerned me. Is this something I should be worried about?
[|AI|]  Hi dear patient! Since you have gallbladder stones you may often feel symptoms related with the gastrointestinal tract disorders, pain, dyspepsia, vomits, jaundice etc. Sometimes the vomits may be strange and the color unusual but in general they're are a kind of green. Black vomits may be caused by your gallbladder problem but also by a possible ulcer of the stomach or duodenum. So the best thing in this case is to do a gastroesophageal endoscopy to have a clearer view of your situation. Take care! Chat Doctor.
