why did i throw up yellow

Throwing up yellow vomit usually means you are vomiting bile, a yellow digestive fluid made by the liver and stored in the gallbladder. This typically happens when the stomach is empty, such as after vomiting all the food from the stomach, during morning sickness, dehydration, or after heavy drinking on an empty stomach. Other common causes include bile reflux (when bile backs up into the stomach and esophagus), intestinal blockage, medication side effects, or certain medical conditions like bowel obstruction or surgery complications. If you vomit yellow bile occasionally when your stomach is empty, it is usually not serious. However, frequent vomiting of yellow bile, especially with symptoms like abdominal pain, bloating, constipation, or weight loss, could indicate a more serious issue like bile reflux or intestinal blockage, which requires medical attention. Lifestyle factors, such as avoiding alcohol, smoking, eating smaller meals, and staying hydrated, can help reduce bile vomiting. If yellow vomiting happens repeatedly or is accompanied by other concerning symptoms, it is important to see a healthcare provider to determine the cause and appropriate treatment.
