What Are Esophageal Varices?
The esophagus is the “food pipe" that connects your throat to your stomach. Esophageal varices happen when veins in the esophagus become enlarged.
Esophageal varices occur most often in people with cirrhosis or scarring of the liver.
At least half the people who have cirrhosis end up with these swollen veins. They often appear in the lower part of the esophagus, near the stomach.
Because they can burst and bleed spontaneously, esophageal varices can be life-threatening.
Causes of esophageal varices
Portal hypertension is the main cause of esophageal varices.
Portal hypertension is high blood pressure in the portal vein system that delivers blood to the liver. It's not the same as regular high blood pressure.
Cirrhosis of the liver is almost always the cause of portal hypertension.
Scarring decreases the amount of blood that can pass through the liver, and the blood has to find new pathways. Sometimes those pathways are veins in the esophagus and stomach.
Since these veins can't handle a high volume of blood, they can develop bulges that leak blood or rupture. These are esophageal varices.
Esophageal varices risk factors and complications
Anyone with liver disease is at risk for esophageal varices, but cirrhosis is the most common risk factor.
If you've had one episode of bleeding esophageal varices, you're likely to have more.
The increased blood flow in the veins of the esophagus and stomach can stretch parts of the veins like balloons.
If the vein bursts, bleeding can cause shock and death if you don't get treatment right away.
How to prevent esophageal varices
The only way to prevent this condition is to keep your liver healthy. People who drink too much alcohol or have hepatitis are at risk for liver disease.
If you have liver disease, you can prevent further damage by:
- Eating a healthy diet.
- Maintaining a healthy weight.
- Not drinking alcohol.
- Seeing your liver doctor on a routine basis.
