What Are Esophageal Varices?
Esophageal varices are swollen veins in the lower part of the esophagus. The esophagus is the tube that carries food from your mouth to your stomach. These veins become enlarged when blood flow to the liver is blocked, often due to liver disease. As a result, blood backs up and causes pressure in the veins. This can make them swell and sometimes burst. Because of this, esophageal varices are a serious liver complication that needs quick attention.
Symptoms of Esophageal Varices
Often, esophageal varices do not cause symptoms until they bleed. However, knowing the warning signs can help you act fast. For example, you may notice:
Sometimes, mild symptoms like tiredness or pale skin can appear. But, bleeding is the most serious sign. If you notice any of these, seek medical help right away.
Causes and Risk Factors
Most often, esophageal varices develop due to liver disease. For instance, cirrhosis, which is scarring of the liver, is a common cause. When the liver is scarred, blood cannot flow through it easily. This raises pressure in the portal vein, which carries blood to the liver. As a result, veins in the esophagus swell.
Other risk factors include:
Because these risks are common worldwide, people in all locations should be aware.
How Esophageal Varices Are Diagnosed
Doctors use several tests to find esophageal varices. First, they may ask about your symptoms and medical history. Next, they often use an endoscopy. In this test, a thin tube with a camera is passed down your throat. This lets the doctor see the veins in your esophagus. In addition, blood tests and imaging scans, like ultrasound, can help check liver health. Early diagnosis is important to prevent bleeding and other liver disease complications.
Treatment Options
Treatment for esophageal varices aims to prevent bleeding and manage liver disease. If bleeding occurs, doctors act quickly to stop it. Common treatments include:
Because each case is different, your doctor will choose the best treatment for you.
Prevention and Lifestyle Tips
While not all cases can be prevented, you can lower your risk. For example, you can:
In addition, following your doctor’s advice and taking prescribed medicines can help prevent esophageal varices from getting worse.
When to Seek Medical Help
It is important to know when to get help. If you vomit blood or notice black stools, seek emergency care right away. Also, if you feel dizzy, weak, or faint, call your doctor. Early treatment can save lives. Even if you have mild symptoms, it is best to talk to a healthcare provider. Because esophageal varices can be life-threatening, do not wait to get help.
