Quick answer
What is Meckel's diverticulum?
Meckel's diverticulum is a small pouch (diverticulum) that sticks out from the wall of the small intestine. It is the most common congenital (present from birth) abnormality of the gastrointestinal tract, arising from a remnant of a structure that was present during development in the womb but usually disappears before birth.
- How it is treated: The approach depends entirely on whether the Meckel's diverticulum is causing problems.
- Self-care: A symptom-free Meckel's diverticulum needs no treatment or lifestyle changes and can be left alone.
- When to seek help: See a doctor, or seek urgent care, about significant blood in a child's stool (which can be painless), tummy pain that could be appendicitis, or symptoms of a bowel obstruction — a Meckel's diverticulum is one possible cause and can be treated.
What it is
Meckel's diverticulum is a small pouch (diverticulum) that sticks out from the wall of the small intestine. It is the most common congenital (present from birth) abnormality of the gastrointestinal tract, arising from a remnant of a structure that was present during development in the womb but usually disappears before birth. It is present in a small percentage of people. The great majority of Meckel's diverticula cause no symptoms at all and are never noticed, often being found by chance (for example during surgery or a scan for another reason) or not at all — so for most people it is a harmless, silent finding. However, in a minority (more often in children), it can cause problems. This is partly because the pouch sometimes contains a small amount of tissue like that of the stomach lining, which can produce acid and cause an ulcer and bleeding in the nearby bowel. The main complications include: painless bleeding from the bottom (a common way it presents in young children, sometimes causing dark or bright red blood in the stool); inflammation of the pouch (which can mimic appendicitis, causing tummy pain); and bowel obstruction (if the pouch causes the bowel to twist or become blocked). Because these complications can be significant, a symptomatic Meckel's diverticulum is treated, but an incidental, symptom-free one is usually left alone.
How it is treated
The approach depends entirely on whether the Meckel's diverticulum is causing problems. The great majority, which are symptom-free and often found by chance, need no treatment and can be left alone, as complications are uncommon and the pouch is harmless in most people. Where a Meckel's diverticulum causes complications, it is treated, usually with surgery to remove the pouch (and any affected bowel). For example: if it causes bleeding (a common presentation in children), the diagnosis is made (a special scan can detect the stomach-like tissue that causes the bleeding), and the diverticulum is removed to stop the bleeding; if it causes inflammation (mimicking appendicitis) or a bowel obstruction, surgery treats this. Because a symptomatic Meckel's diverticulum can present as an emergency (such as significant bleeding, or an obstruction), these situations need prompt assessment and treatment. When a Meckel's diverticulum is found incidentally during surgery for another reason, whether to remove it is decided case by case. The reassuring message is that a Meckel's diverticulum is a common, usually harmless finding that most people never know they have, and that, in the minority where it causes problems (such as bleeding, inflammation or obstruction, mainly in children), it is effectively treated with surgery.

Beyond medication
Lifestyle and self-care
A symptom-free Meckel's diverticulum needs no treatment or lifestyle changes and can be left alone. There are no specific measures to prevent complications; the key is seeking assessment if symptoms occur (such as bleeding from the bottom in a child, or tummy pain), so a symptomatic diverticulum can be treated.
When to get help
When to see a doctor
See a doctor, or seek urgent care, about significant blood in a child's stool (which can be painless), tummy pain that could be appendicitis, or symptoms of a bowel obstruction — a Meckel's diverticulum is one possible cause and can be treated. A symptom-free diverticulum found by chance usually needs no action.

Answers
Meckel's diverticulum: frequently asked questions
What is a Meckel's diverticulum?
It is a small pouch present from birth that sticks out from the small intestine — the most common congenital abnormality of the gut. The great majority cause no symptoms and are harmless, but a minority (more often in children) can cause bleeding, inflammation, or a bowel obstruction.
Does a Meckel's diverticulum need treatment?
Only if it causes problems. Most are symptom-free and are left alone. Where it causes complications — such as bleeding (common in children), inflammation mimicking appendicitis, or a bowel obstruction — it is treated with surgery to remove the pouch.
