Hangover Vomiting Bile: What To Eat To Stop It

Why Do Hangovers Cause Vomiting Bile?

Waking up after a night of heavy drinking with nausea and vomiting bile is one of the most unpleasant hangover symptoms. Excessive alcohol consumption irritates and dehydrates the stomach lining, which can cause bile reflux—when digestive fluids from the liver back up into the stomach, esophagus, and mouth.

According to research from Colorado State University, this reaction is the result of alcohol-induced irritation and inflammation in the stomach, leading to nausea, retching, and eventually vomiting bile.


Signs and Symptoms of Vomiting Bile After Drinking

Vomiting bile after a hangover is different from nausea caused by food poisoning, pregnancy, or infections. Unlike gastric acid reflux, which involves stomach acid, bile reflux involves digestive fluids produced in the liver.

Common symptoms include:

  • Greenish-yellow vomit (bile)
  • Burning sensation in the chest or throat (caused by digestive fluids irritating the esophagus)
  • Persistent coughing
  • Pain in the upper abdomen
  • Nausea and dry heaving on an empty stomach

Recognizing these signs is important to avoid complications and determine when to seek medical care.


Main Causes of Throwing Up Bile After Drinking

1. Bile Reflux From Alcohol Irritation

Alcohol inflames the stomach lining and disrupts digestion. On an empty stomach, the body has no food to expel, leading to vomiting bile instead.

2. Empty Stomach During a Hangover

Skipping meals before or after drinking increases the chances of vomiting bile since the stomach has no other contents.

3. Gallbladder Inflammation (Cholecystitis) and Liver Damage

People with gallbladder issues or liver disease may also vomit bile. Their symptoms may overlap with hangover nausea but require immediate medical evaluation.


Dangers of Vomiting Bile From a Hangover

Occasional bile reflux after drinking may not be dangerous, but repeated or severe episodes can lead to complications such as:

  • Dizziness and fainting
  • Stomach ulcers and bleeding
  • Severe heartburn and esophageal damage
  • Irregular heartbeat
  • Chronic digestive issues
  • Vomiting blood due to ruptured esophageal veins (common in people with alcoholism)

👉 While it’s rare to die from a hangover, frequent vomiting bile can cause long-term damage to the digestive system if ignored.


What to Do After Throwing Up Bile

Rehydrate First

Alcohol and vomiting both dehydrate the body. After a bile reflux episode:

  • Drink clear liquids such as water, herbal teas, diluted apple juice, or broth.
  • Avoid citrus juices, coffee, and milk, which can worsen irritation.
  • Take small sips at first to avoid triggering more nausea.
  • Use an oral rehydration solution (ORS) if vomiting continues for more than 24 hours.

Eat Light, Gentle Foods

After rehydrating, start with bland, easy-to-digest foods:

  • Plain toast, crackers, or rice
  • Bananas or applesauce
  • Plain oatmeal or broth-based soups

Avoid greasy, spicy, or highly fragrant foods that can worsen nausea.


When to See a Doctor

Seek immediate medical attention if vomiting bile after drinking is accompanied by:

  • Severe abdominal pain
  • Blood in vomit
  • Dehydration or muscle cramps
  • Stiff neck and extreme lethargy
  • Rapid or irregular breathing
  • Fever, vertigo, or hangover-related “inflamed response” (hangover fever)

These symptoms may indicate a serious complication that requires urgent treatment.


How to Prevent Vomiting Bile From Hangovers

Prevention is always better than cure. To lower your risk:

  • Eat before and during drinking – keeping the stomach full helps prevent bile reflux.
  • Stay hydrated – drink water between alcoholic beverages to reduce irritation and dehydration.
  • Avoid binge drinking – limiting intake reduces the risk of nausea, bile reflux, and long-term damage.

💡 Many people believe “throwing up helps a hangover.” In reality, vomiting does not speed up alcohol metabolism—by the time hangover symptoms appear, alcohol is already processed. Vomiting only worsens dehydration.


Final Thoughts: Recovery and Alcohol Addiction Treatment

Occasional hangover nausea can be managed at home with rest, hydration, and proper diet. However, frequent bile reflux after drinking is a warning sign that your body is struggling.

If you experience repeated episodes, it may be time to reconsider your relationship with alcohol. Long-term recovery is possible with professional help, including alcohol addiction rehab programs that provide medical detox, therapy, and support groups.

👉 Seeking treatment today can prevent chronic health problems and open the door to a healthier, sober life.
