The World’s First Diverticular Disease Awareness Week!

2nd October 2023

This week (2nd-8th October) is the World’s First Diverticular Disease Awareness Week! Have you heard of it?

Diverticular disease affects 1 in 3, increasing to 1 in 2 people during their lifetime. Diverticula are permanent pockets that develop in the bowel and in some people, they can cause symptoms.

What does diverticular disease look like?

The terminology surrounding diverticular disease can get a little confusing, so let’s break it down:

  • Diverticulum: A diverticulum is a small pouch about 1cm in size which sticks out from the wall of the large bowel.
  • Diverticula: This refers to more than one Diverticulum. The most common site for diverticula is on the lower part of the large bowel on the left-hand side. They are permanent unless the affected part of the bowel is surgically removed.
  • Diverticulitis: Diverticulitis means the condition that occurs when a single diverticulum or several diverticula become inflamed or infected.
  • Diverticulosis: You may have heard the term diverticulosis, which means the presence of diverticula, this is not the same as diverticular disease. Most people with diverticulosis do not have, or go on to develop, diverticular disease. The great majority of people with diverticulosis will live out their lives never having symptoms. Having symptoms is diagnosed as diverticular disease.

How can diverticular disease affect you?

Most people with diverticular disease will never have any complications and can carry on with their daily lives as normal, but there are people who will be greatly affected by symptoms of diverticular disease.


The most common symptoms are:

  • Lower abdominal pain
  • Bloating (increase in abdominal size due to gas)
  • Change in bowel habit (diarrhoea or constipation)
  • Mucus or blood in the stool

The pain is commonly focussed on the left side of the abdomen (belly) where the diverticula most often occur. In a small number of people, and people of South Asian origin, symptoms may occur on the right-hand side of the abdomen.

This week, we’re also raising awareness of the symptoms of diverticulitis (when the pocket/s can become infected). Diverticulitis can occur within between 1 in 10 to a quarter of people with the condition, so it’s crucial that you know the symptoms. If any of the below symptoms are experienced, seek medical help immediately:

  • Worsening abdominal pain
  • High temperature
  • Nausea (feeling sick) or vomiting (being sick)
