This typically starts with a review of your medical history and a physical exam.īased on the initial findings, your healthcare provider may order: If you've vomited what appears to be yellow bile, your healthcare provider will want to run tests to investigate the most likely causes.
The classes of drugs most commonly associated with this include: Certain MedicationsĬertain medications can relax the pylorus sphincter, causing bile to seep into the stomach. Chest pain, sore throat, and a bitter mouth taste are also common. This can lead to vomit that is greenish-yellow, sticky, and possibly tinged with blood (if tiny blood vessels in the esophagus rupture). When you vomit on an empty stomach-due to a severe case of viral gastroenteritis (stomach flu) or Salmonella poisoning, for example-there is really nothing else to vomit but mucus, gastric acid, and bile. Intestinal strictures and blockage are also common in people with colon cancer. People with Crohn's disease, ulcerative colitis, and lupus are at especially high risk of intestinal blockage.
When either of these happens, bile can pool (rather than being excreted in stool) and eventually backflow into the stomach.Īn intestinal blockage can lead to symptoms like:Īn intestinal blockage can be caused by fecal impaction (in which hardened stools become stuck) and intestinal stricture (the abnormal narrowing of the intestinal passageway). Intestinal BlockageĪn intestinal blockage occurs when the intestines are either obstructed physically or damaged by disease. Upper abdominal surgery, trauma, and long-standing gastroesophageal reflux disease (GERD) can also compromise the diaphragm, increasing the risk of a hernia.Ī hiatal hernia can also cause heartburn, upset stomach, throat irritation, belching, and regurgitation. The compression of the stomach can place pressure on all of the sphincters of the stomach, including the pyloric sphincter and LES.Ī hiatal hernia is more common in older adults and people with obesity. Hiatal HerniaĪ hiatal hernia occurs when part of the stomach protrudes up into the chest through a thin muscle called the diaphragm. Bile reflux can occur on its own but is common with acid reflux. Other symptoms of bile reflux include diarrhea, heartburn, abdominal pain, and a foul taste in the mouth.
A peptic ulcer can also damage the pyloric sphincter either directly (by causing tissue injury) or indirectly (by increasing stomach pressure which disrupts the valve). There are many reasons why this might occur:īile reflux occurs when the muscular passageway between the stomach and small intestine-called the pyloric sphincter-malfunctions, allowing bile to seep into the stomach and then the esophagus.īile reflux is similar to acid reflux in which stomach acids seep from the stomach into the esophagus because of a dysfunctional sphincter.īile reflux often develops after gallbladder surgery and other upper gastrointestinal surgeries (like a gastric bypass). Yellow vomit occurs when bile backflows from the small intestine into the stomach. During vomiting, the muscular passageway that separates the stomach from the esophagus-known as the lower esophageal sphincter (LES)-will spontaneously open, propelling any contents out of the stomach.
