A diverticulum (plural: diverticula) is a small pouch that sticks out from the side of the colon (large bowel). Diverticula can affect anyone, especially older people. However, they seem to be more common in people with ADPKD than in people without kidney problems.
Most people with diverticula have no symptoms, but when symptoms are present you are said to have diverticular disease.
Causes of diverticular disease
It is unclear why diverticular disease is more common in people with ADPKD. But factors that generally increase the risk include:
- Older age
- Low levels of fibre in the diet
- Non-steroidal anti-inflammatory drugs (NSAIDs) and paracetamol
Symptoms of diverticular disease
Symptoms of diverticular disease may include:
- Pain in the abdomen, usually on the lower-left side
- Pain that gets worse with eating and gets better with defecation
- Sometimes bloating or constipation
- Sometimes bleeding from the rectum.
Diagnosing diverticular disease
Diverticular disease can be difficult to diagnose, because the symptoms can be similar to those of other problems such as irritable bowel syndrome.
Your doctor will examine you physically and check your medical history (including any history of diverticular disease). Your doctor may recommend blood tests to rule out other problems, and to see if you have an infection. You may also need to have a colonoscopy or a barium enema X-ray to confirm that you have diverticula.
Treating diverticular disease
Diverticular disease can usually be treated at home with:
- Paracetamol for pain
- A high-fibre diet
- Laxatives for constipation
- Plenty of fluids.
If your diverticular symptoms are severe or do not improve with home treatment, contact your GP.
Preventing diverticular disease
At present, there are no specific measures to prevent diverticular disease in people with ADPKD. General advice to reduce the risk includes:
- Eat a high-fibre diet
- Do not smoke
- Maintain a healthy weight
- Avoid NSAIDs
- You can find detailed information and advice on diverticular disease and dietary fibre on the website of CORE, a charity funding research into digestive problems.
- The Bladder and Bowel Community has a useful leaflet on its site and their helpline is 01926 357220.
- The Royal College of Radiologists has information about having a barium enema X-ray.
- There is information about colonoscopy at www.patient.co.uk.
