Avoiding Diverticulitis

‘ A clever person solves a problem, a wise one avoids one’

Albert Einstein

Throughout this website you will find our recommendations for ‘avoidance’ of dietary issues and we could not be any more forthright than with this particular issue.

Below we have a list of dietary recommendations to help you to avoid diverticulitis.  We are aware that IBS-d sufferers may have problems with excessive fiber intakes, in those instances we recommend that you consult with a dietitian or doctor.  

Gentle fiber, such as Psyallium husk may be the answer for certain types of IBS.

Preventing diverticular disease and diverticulitis

Eating a high-fibre diet may help prevent diverticular disease, and should improve your symptoms.

Your diet should be balanced and include at least five daily portions of fruit and vegetables, plus whole grains. Adults should aim to eat between 18g (0.6oz) to 30g (1.05oz) of fibre a day, depending on their height and weight. Your GP can provide a more specific target, based on your individual height and weight.

It is recommended you gradually increase your fibre intake over the course of a few weeks. This will help prevent side effects associated with a high-fibre diet, such as bloating and flatulence (wind). Some specialists may suggest not eating nuts, corn and seeds due to the possibility that they could block the diverticular openings and cause diverticulitis. However, there is limited evidence to support this.

Also drinking plenty of fluids will help prevent side effects.
