Meckel's Diverticulum

Meckel’s diverticulum can cause cramping in the abdomen, nausea, and vomiting in people of all ages. Similar to appendicitis, acute Meckel diverticulitis is characterized by abdominal discomfort and tenderness that is usually situated below or next to the umbilicus. It is sometimes followed by vomiting, bright red, and painless rectal bleeding in children is possible. Adults can bleed too, although usually it’s melena instead of plain blood.
