What causes vomiting of bitter yellow fluid?

Generally, vomiting bitter yellow fluid may be caused by unhygienic diet, excessive alcohol consumption, bile reflux gastritis, cholecystitis, or liver dysfunction. If discomfort occurs, it is recommended to seek medical attention promptly. Specific causes are analyzed as follows:

1. Unhygienic Diet

After consuming contaminated food, the gastrointestinal tract becomes irritated, triggering a vomiting response. When vomiting is frequent and severe, gastrointestinal motility may change, causing bile to reflux from the duodenum into the stomach and subsequently be expelled in vomit. It is important to maintain clean and hygienic eating habits and consume cooked foods.

2. Excessive Alcohol Consumption

After heavy drinking, alcohol strongly irritates the gastric mucosa, leading to nausea and vomiting. Once stomach contents are fully expelled, bile may continue to be vomited, appearing as bitter-tasting yellow fluid. It is advisable to abstain from alcohol and develop good hygiene habits in daily life.

3. Bile Reflux Gastritis

Bile reflux gastritis is primarily caused by gastrointestinal dysmotility or dysfunction of the pyloric sphincter. This condition allows bile to flow back into the stomach, irritating the gastric mucosa and causing inflammation, which leads to the aforementioned symptoms. It may be accompanied by bloating and belching. Treatment under medical guidance may include medications such as hydrotalcite chewable tablets, domperidone tablets, and ranitidine hydrochloride capsules.

4. Cholecystitis

Poor dietary habits, bacterial infections, or gallstones may lead to cholecystitis. Inflammation can cause abnormal bile secretion, irritating the digestive tract and resulting in vomiting, with bile giving the vomit a bitter taste. Symptoms may include right upper abdominal pain and fever. Patients should follow medical advice and take medications such as ursodeoxycholic acid tablets, racemic hyoscine butylbromide tablets, and cefixime tablets.

5. Liver Dysfunction

Liver dysfunction can result from various factors, including viral infections, improper medication use, and excessive alcohol consumption. When liver function is impaired, bile metabolism becomes abnormal, potentially causing bile to reflux into the stomach and trigger nausea and vomiting with a bitter taste. Symptoms may also include jaundice and liver area pain. Medications such as silibinin capsules, diammonium glycyrrhizinate enteric-coated capsules, and bicyclol tablets may be used under medical supervision.

In daily life, maintaining healthy lifestyle and dietary habits is crucial. Avoid overeating, limit alcohol intake, practice good personal hygiene, and undergo regular health check-ups to help prevent various digestive system disorders and maintain overall health.
