What is a common symptom of Meckel's diverticulum?

A common symptom of Meckel's diverticulum is painless rectal bleeding. This condition is often asymptomatic in many individuals, but when symptoms do occur, painless rectal bleeding is frequently reported, especially in children. This bleeding is typically due to the presence of gastric mucosa in the diverticulum, which can lead to ulceration and subsequent bleeding.

Other symptoms associated with Meckel's diverticulum may include abdominal pain or cramping, but these are less prevalent and more variable. The condition may also lead to intestinal obstruction or diverticulitis, but these complications manifest differently and are not as characteristic as the symptom of painless rectal bleeding. The unique presentation of painless rectal bleeding helps differentiate Meckel's diverticulum from other potential gastrointestinal issues that may involve pain or painful bleeding.
