Causes & Risk Factors
Several factors can contribute to Gastric Varices.
Gastric varices develop primarily due to portal hypertension, a condition where blood pressure increases dramatically in the portal vein system that carries blood from the digestive organs to the liver.
Gastric varices develop primarily due to portal hypertension, a condition where blood pressure increases dramatically in the portal vein system that carries blood from the digestive organs to the liver. When the liver becomes scarred or damaged, blood cannot flow through it normally. This creates a backup of pressure that forces blood to find alternative routes back to the heart.
Liver cirrhosis accounts for the vast majority of cases, regardless of the underlying cause.
Liver cirrhosis accounts for the vast majority of cases, regardless of the underlying cause. Chronic hepatitis B or C, alcoholic liver disease, fatty liver disease, and autoimmune liver conditions all can progress to cirrhosis and subsequent portal hypertension. The damaged liver tissue acts like a dam, forcing blood to seek new pathways through smaller vessels that weren't designed to handle such high pressure and volume.
Less commonly, gastric varices can develop from other conditions that block blood flow in the portal system.
Less commonly, gastric varices can develop from other conditions that block blood flow in the portal system. These include blood clots in the portal or splenic veins, certain cancers that compress major blood vessels, and rare genetic conditions affecting blood vessel development. Schistosomiasis, a parasitic infection common in certain parts of the world, can also cause portal hypertension severe enough to create gastric varices.
Risk Factors
- Advanced liver cirrhosis from any cause
- Chronic alcohol use disorder
- Chronic hepatitis B or C infection
- Non-alcoholic fatty liver disease
- Portal vein thrombosis or blood clots
- Previous episodes of esophageal varices
- Low platelet count and enlarged spleen
- Family history of liver disease
- Autoimmune liver diseases
- Schistosomiasis infection history
Diagnosis
How healthcare professionals diagnose Gastric Varices:
- 1
Diagnosing gastric varices typically begins when someone with known liver disease develops symptoms of bleeding or during routine screening for portal hypertension complications.
Diagnosing gastric varices typically begins when someone with known liver disease develops symptoms of bleeding or during routine screening for portal hypertension complications. Doctors often suspect the condition in patients with cirrhosis who show signs of internal bleeding, such as vomiting blood or passing black stools. The diagnostic process usually starts with blood tests to check for anemia, liver function, and clotting ability.

Endoscopy represents the gold standard for diagnosing gastric varices.
Endoscopy represents the gold standard for diagnosing gastric varices. During this procedure, a flexible tube with a camera is passed through the mouth into the stomach, allowing doctors to directly visualize the enlarged vessels. The endoscope can reveal the size, location, and appearance of varices, helping doctors assess the risk of bleeding. This procedure also allows for immediate treatment if active bleeding is found.

Additional imaging studies may include CT scans or MRI to evaluate the overall portal system and identify underlying causes.
Additional imaging studies may include CT scans or MRI to evaluate the overall portal system and identify underlying causes. Doppler ultrasound can assess blood flow patterns in the portal and splenic veins. In some cases, doctors may perform specialized tests to measure portal pressure directly. These diagnostic tools help create a complete picture of the patient's condition and guide treatment decisions.
Complications
- Bleeding represents the most serious and immediate complication of gastric varices.
- When these enlarged vessels rupture, they can cause massive blood loss that requires emergency medical intervention.
- Gastric variceal bleeding tends to be more severe than esophageal variceal bleeding because the vessels are often larger.
- Without prompt treatment, bleeding can lead to shock, organ failure, and death.
- Even with treatment, rebleeding occurs in about 30-40% of cases within the first few days.
- Long-term complications include recurrent bleeding episodes, which can cause chronic anemia and reduced quality of life.
- Some patients develop complications from treatments themselves, such as infection or blood clots from endoscopic procedures.
- The underlying portal hypertension can worsen over time, leading to other serious complications like ascites (fluid accumulation in the abdomen), hepatic encephalopathy (brain dysfunction due to liver failure), and progressive liver failure requiring transplantation.
Prevention
- Preventing gastric varices primarily involves addressing the underlying liver disease before portal hypertension develops.
- For people with chronic hepatitis B or C, antiviral medications can slow or prevent progression to cirrhosis.
- Those with alcohol-related liver disease benefit enormously from complete alcohol cessation, which can halt further liver damage and sometimes allow partial recovery of liver function.
- Managing metabolic risk factors plays a crucial role in preventing fatty liver disease progression.
- This includes maintaining a healthy weight, controlling diabetes and cholesterol levels, and following a balanced diet low in processed foods.
- Regular exercise and avoiding unnecessary medications that can harm the liver also contribute to liver health preservation.
- For people already diagnosed with cirrhosis, preventing gastric varices involves regular medical monitoring and early treatment of portal hypertension.
- Beta-blocker medications can reduce portal pressure before varices develop.
- Routine endoscopic screening allows for early detection and treatment.
- Following prescribed treatments for liver disease, avoiding alcohol completely, and maintaining good nutrition with adequate protein intake can help slow disease progression and reduce complication risks.
Emergency treatment focuses on controlling active bleeding, which can be life-threatening.
Emergency treatment focuses on controlling active bleeding, which can be life-threatening. When gastric varices rupture, doctors may use endoscopic techniques to inject special glue or coils directly into the bleeding vessels. This procedure, called endoscopic obturation, can effectively stop bleeding in most cases. Patients often receive blood transfusions and medications to support blood pressure and prevent complications.
For stable patients or those at high risk of bleeding, preventive treatments aim to reduce pressure in the portal system.
For stable patients or those at high risk of bleeding, preventive treatments aim to reduce pressure in the portal system. Beta-blockers like propranolol or nadolol can lower portal pressure and reduce bleeding risk. Some patients benefit from procedures called TIPS (transjugular intrahepatic portosystemic shunt), which creates an artificial connection between portal and systemic circulation, effectively bypassing the liver and reducing pressure on gastric varices.
Balloon-occluded retrograde transvenous obliteration (BRTO) offers another treatment option, particularly for larger gastric varices.
Balloon-occluded retrograde transvenous obliteration (BRTO) offers another treatment option, particularly for larger gastric varices. This specialized procedure blocks the veins that feed the varices, causing them to shrink over time. While more complex than endoscopic treatments, BRTO can be highly effective for preventing rebleeding in carefully selected patients.
Long-term management focuses on treating the underlying liver disease and monitoring for complications.
Long-term management focuses on treating the underlying liver disease and monitoring for complications. This may include antiviral medications for hepatitis, lifestyle changes for fatty liver disease, or evaluation for liver transplantation in advanced cases. Regular endoscopic surveillance helps detect changes in varix size or appearance that might indicate increased bleeding risk. New research into portal pressure reduction and liver regeneration therapies offers hope for improved treatments in the future.
Living With Gastric Varices
Living with gastric varices requires ongoing medical care and lifestyle adjustments to reduce bleeding risk. Regular follow-up appointments with gastroenterologists and hepatologists become essential for monitoring the condition and adjusting treatments as needed. Many people benefit from keeping a symptom diary to track any changes that might indicate complications, such as fatigue, dizziness, or changes in stool color.
