Watermelon stomach is a medical condition also referred to as gastric antral vascular ectasia (GAVE) that causes chronic bleeding in the stomach lining. The term "watermelon" refers to the appearance of the stomach lining which appears striped like the flesh of a watermelon. The word "stomach" is spelled as /ˈstʌm.ək/ in IPA phonetic transcription. The stress is on the first syllable, and it has a short "u" sound. This condition can lead to anemia, and treatment usually involves endoscopic therapy or surgery.
Watermelon stomach, also known as gastric antral vascular ectasia (GAVE), refers to a specific medical condition characterized by enlarged blood vessels in the lining of the stomach that resemble the stripes on a watermelon, thereby lending the name. It is a rare disorder mainly affecting the mucosa layer in the gastric antrum, the lower part of the stomach.
The condition causes the blood vessels in the stomach to dilate and become prominent, forming longitudinal red streaks that often extend across the stomach’s lining. These abnormally enlarged blood vessels create a distinctive appearance, hence the name "watermelon stomach." As a result, affected individuals may experience intermittent or chronic gastrointestinal bleeding, leading to symptoms such as chronic anemia, blood in the stool, and melanotic stool (tarry, dark stools due to digested blood).
The specific cause of watermelon stomach remains unclear, but there seem to be associations with other underlying conditions such as cirrhosis, autoimmune diseases, and chronic renal failure. Mucosal injury caused by changes in blood flow and abnormal blood vessels' structure has been proposed as the primary mechanism responsible for bleeding.
Diagnosis is typically made through endoscopic examination, during which the characteristic striped pattern can be observed. Further tests may include biopsies to rule out other conditions and assess the extent of the bleeding.
Treatment options for watermelon stomach aim to control bleeding and alleviate associated symptoms. This commonly involves endoscopic procedures such as laser therapy, electrocautery, argon plasma coagulation, or injection of sclerosing agents to reduce blood flow and stop bleeding vessels. In severe cases, surgical intervention may be considered to remove the affected portion of the stomach.
The term "Watermelon Stomach" is a colloquial name for a medical condition known as gastric antral vascular ectasia (GAVE). The term originated from the appearance of the condition, where the lining of the stomach develops red spots and stripes that resemble the outer skin of a watermelon.
The etymology of the word "Watermelon" is rooted in Old English and Middle English. The word "water" comes from the Old English word "wæter", which evolved from the Proto-Germanic word "watar". "Melon" comes from the Middle English word "melon", derived from the Old French word "melon", meaning "fruit". The term "watermelon" was first recorded in the English language in the 1530s.
