Diverticular Disease
DIVERTICULAR DISEASE
What is Diverticular disease?
Diverticular disease is a common condition where small pouches, called diverticula, form in the wall of the large intestine (colon). When these pouches are present without causing symptoms, the condition is called diverticulosis. Diverticula become more common with age, especially after 50, and many people never know they have them. They may be picked up on a routine colonoscopy.
Diverticulitis occurs when one or more of these pouches become inflamed or infected. This can cause symptoms such as ongoing abdominal pain (often on the lower left side), fever, nausea, and changes in bowel habits.
Mild diverticulitis can often be managed at home with rest, temporary changes to diet, and sometimes antibiotics. More severe or recurring episodes may require hospital treatment and, in some cases, surgery. With the right medical and nutrition support, most people recover well and can manage the condition long term.
The cause of diverticulosis is still unknown. Some risk factors for diverticular disease include low dietary fibre intake , high red meat intake , drinking too much alcohol and being overweight. Genetics are also an influencing factor.
How can a dietitian help me?
A dietitian can help improve your diet quality, increase dietary fibre intake, and support the management of symptoms. If you have been excluding higher-fibre foods, a dietitian can guide you in gradually reintroducing fibre-rich foods back into your diet with confidence. We are also skilled at supporting positive lifestyle changes, which may further contribute to improved outcomes.
