Vomiting Yellow Fluid What Are The Causes

Vomiting yellow fluid is typically associated with bile reflux. When vomiting is severe and occurs frequently, the contents of the stomach can be completely expelled. Continued vomiting may then cause bile and digestive fluids to be regurgitated as well. Bile is naturally bitter and yellow in color, which explains why the vomit may appear as yellow fluid. There are several potential reasons for vomiting, including the expulsion of yellow fluid, and these can range from physiological changes to serious underlying conditions.

Pregnancy
In women of childbearing age, vomiting yellow fluid may be related to pregnancy. Morning sickness during early pregnancy can cause persistent nausea and vomiting. In more severe cases, excessive vomiting may lead to the expulsion of yellow bile.

Poisoning
Food poisoning is a common cause of vomiting and can lead to the appearance of yellow fluid. Additionally, alcohol poisoning or medication toxicity—especially from drugs like macrolide antibiotics that affect gastrointestinal motility—can also result in vomiting bile.

Medical Conditions
Various digestive system disorders such as acute gastritis, gallbladder inflammation, gallstones, pancreatitis, intestinal obstruction, and acute gastroenteritis can all cause vomiting with yellow fluid. Moreover, central nervous system conditions like increased intracranial pressure or hypertensive crisis may also lead to vomiting, sometimes accompanied by other neurological symptoms.

If you experience persistent vomiting with yellow fluid, it is important to seek care from a gastroenterologist to identify the underlying cause. Severe vomiting can lead to dehydration and electrolyte imbalances, so prompt rehydration is essential. Under medical supervision, medications that reduce stomach acid and protect the gastric lining may be prescribed to help alleviate symptoms and promote recovery.
