Gastric Antral Vascular Ectasia: Causes, Symptoms, And Treatment
Gastric antral vascular ectasia (GAVE), also known as watermelon stomach, is a rare condition that affects the blood vessels in the stomach lining. The exact cause of GAVE is not fully understood, but it is believed to be related to changes in the blood vessels that supply the stomach. These changes can lead to dilated blood vessels and cause bleeding in the stomach. If you have been diagnosed with GAVE, your healthcare provider can provide you with more information and guidance on managing this condition.
What Are the Symptoms of Gastric Antral Vascular Ectasia
Gastric antral vascular ectasia can cause symptoms such as abdominal pain, nausea, vomiting, and blood in the stool or vomit. Patients may experience fatigue, weakness, and anemia due to chronic blood loss. Additionally, this condition can lead to gastrointestinal bleeding, which may manifest as dark, tarry stools. Seek medical attention if you experience these symptoms.
- One common symptom of gastric antral vascular ectasia is sudden and persistent stomach pain.
- People with this condition may experience frequent episodes of black or bloody stools.
- Another sign of gastric antral vascular ectasia is unexplained weight loss and fatigue.
- Patients might notice dark, tarry vomit, which can be a symptom of this gastrointestinal disorder.
- Some individuals with gastric antral vascular ectasia may feel lightheaded or dizzy due to internal bleeding.

Other potential triggers include aging, chronic kidney disease, and certain medications like nonsteroidal anti-inflammatory drugs. The exact cause of this condition is not fully understood, but these factors are thought to play a role.
- Chronic liver disease, such as cirrhosis, is a known risk factor for the development of gastric antral vascular ectasia.
- Autoimmune conditions, such as scleroderma and systemic sclerosis, have been associated with an increased likelihood of gastric antral vascular ectasia.
- Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) can contribute to the development of gastric antral vascular ectasia.
- Chronic kidney disease is another systemic condition that has been linked to the formation of gastric antral vascular ectasia.
- Infection with the bacteria Helicobacter pylori has been suggested as a potential cause of gastric antral vascular ectasia in some cases.
Types Of Gastric Antral Vascular Ectasia
- Watermelon stomach is a type of gastric antral vascular ectasia characterized by red streaks resembling the stripes on a watermelon, which are caused by dilated blood vessels in the stomach lining.
- Portal hypertensive gastropathy is another form of gastric antral vascular ectasia that is commonly seen in patients with liver cirrhosis, resulting from increased pressure in the portal vein system leading to vascular abnormalities in the stomach.
- Autoimmune-related gastric antral vascular ectasia can occur in patients with autoimmune conditions such as systemic sclerosis, where abnormal immune responses lead to vascular changes in the antrum of the stomach.
- Idiopathic gastric antral vascular ectasia refers to cases where the cause of the condition is unknown
Risk Factors
Understanding these risk factors can help in early detection and management of gastric antral vascular ectasia.
- Chronic liver disease: Individuals with conditions such as cirrhosis or hepatitis are at higher risk for developing gastric antral vascular ectasia.
- Advanced age: Older adults, especially those over the age of 60, have an increased likelihood of developing gastric antral vascular ectasia.
- Autoimmune diseases: Conditions like scleroderma and systemic sclerosis are associated with an elevated risk of gastric antral vascular ectasia.
- Kidney disease: Patients with chronic kidney disease, particularly those on dialysis, are more prone to developing gastric antral vascular ectasia.
- Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs):

Diagnosis of Gastric Antral Vascular Ectasia
Early diagnosis can lead to effective treatment to manage symptoms and prevent complications.
- Upper Endoscopy: A common diagnostic method for gastric antral vascular ectasia involves inserting a thin, flexible tube with a camera (endoscope) into the esophagus to visualize the stomach lining and identify abnormal blood vessels in the antrum.
- Endoscopic Ultrasound: This procedure uses sound waves to create detailed images of the gastrointestinal tract, helping to assess the extent and severity of vascular abnormalities in the antrum.
- Capsule Endoscopy: In some cases, a tiny wireless camera enclosed in a capsule is swallowed to capture images of the digestive system, including the antral area, providing valuable information on the presence of vascular ectasia.
Treatment for Gastric Antral Vascular Ectasia
Treatment options for gastric antral vascular ectasia include endoscopic therapies like argon plasma coagulation and band ligation to help stop bleeding. Medications such as proton pump inhibitors can also be prescribed to reduce stomach acid and promote healing. In severe cases, surgical procedures may be necessary to control bleeding. Following a healthy diet and lifestyle changes are also important for managing symptoms.
- Endoscopic therapy, such as argon plasma coagulation or laser therapy, is often used to treat gastric antral vascular ectasia by cauterizing the abnormal blood vessels in the stomach lining.
- Iron supplementation may be prescribed to manage anemia associated with gastric antral vascular ectasia, as chronic bleeding from the abnormal blood vessels can lead to iron deficiency.
- Medications like proton pump inhibitors or tranexamic acid may be recommended to help reduce stomach acid production and prevent further irritation of the blood vessels in the gastric antrum.
- In some cases, surgical intervention, such as a gastrectomy or endoscopic mucosal resection, may be necessary to remove the affected portion of
