What you are describing - yellow/orange vomit - really sounds like bile to me!
I would suggest that you find out if there is a Teaching Hospital close to you with a Gastro Enterologist on board and you might have to go for an Endoscopy (swallowing a camera that can see from your throat to your Deodenum) and some bloodtests to check your Liver function.
It does sound like bile......maybe you have bile reflux!?!?
An endoscopy should be considered to have a look I think.....I hope you can get some relief soon
Hello and hope you are doing well.
Your persisting symptom of vomiting could be due to bowel obstruction. This could be a partial obstruction The other causes could be GERD (Gastro Esophageal Reflux Disease), where the acid contents of the stomach came up into the esophagus and peptic ulcer disease. Please consult your primary care physician for further evaluation. In the meantime take oral fluids.
Hope this helped and do keep us posted.
