Dear Raquel,

Many thanks for your question regarding your client suffering with diverticular disease. You mentioned that the symptoms appear to worsen after a period of stress and certainly this could well have played a key role in her ongoing symptoms. It may be the case that more attention is needed to support her innate immune system and provide beneficial probiotics rather than using anti-microbials at this point. In addition, supporting the gut barrier health and the production of short chain fatty acids may be helpful.

Diverticula are small pouches or pockets in the wall of the digestive system, most often the large intestine. When these pouches become inflamed, this characterizes diverticular disease. Diverticula are quite common in older individuals, and often do not cause symptoms.

A person who has diverticula without inflammation or any associated symptoms is said to have diverticulosis, a term that simply denotes the presence of diverticula in the large intestine. Diverticula form as a result of a complex interaction of age, diet, and structural and functional changes in the nerves and muscles of the colon wall. These factors may contribute to weakness of and increased pressure on the colon wall. It used to be thought that mechanical obstruction of diverticula by fecal matter or undigested food particles caused diverticular disease, but newer research suggests that changes in the microbial composition of the intestinal tract (which can create a pro-inflammatory environment) and changes in colon motility are important contributors – therefore the current dysbiotic changes seen may be relevant.

Acute diverticulitis causes pain in the lower left abdomen that tends to worsen with movement which interestingly she appears to be suffering with although you mention that at present the GP does not think there is inflammation of the diverticula. However, it does appear there is irritation of the bowel. Often when there is a flare up it is recommended to switch to a low residue diet. Some people also find that a few days of liquid diets such as soups etc can also be helpful to reduce the irritation.

It is difficult to ascertain whether her current symptoms are actually due to the presence of the dysbiotic bacteria. However, you can look at addressing dysbiosis and introducing interventions to calm irritation and reduce symptoms at this stage.

Probiotics. By helping restore the balance of intestinal flora and reduce inflammation in the colon, probiotic supplementation may be of benefit in both acute and chronic diverticular problems.

In an open-label trial, a combination of Lactobacillus acidophilus 145 and Bifidobacterium species 420 was found to be effective for preventing disease recurrence in people with symptomatic uncomplicated diverticular disease (SUDD).

Butyrate: Butyrate is a short-chain fatty acid produced in humans by intestinal bacteria that digest and metabolize fiber. Butyrate is critical to colonic mucosal health; is the preferred fuel of the cells that line the interior of the colon; helps maintain the intestinal barrier; has anti-inflammatory and anti-cancer effects; and helps regulate colonic motility.

In a randomized clinical trial of sodium butyrate in 52 people with diverticular disease, less than 7% of those in the butyrate group experienced diverticulitis symptoms compared with slightly more than 31% in the placebo group.

Fibre: Initially I would start on a low residue diet and then gradually increase fibre until consumption reaches 20–30 g of fibre daily which has been recommended by some diverticular disease researchers. Supplemental fibre in a form like ground psyllium seed or apple pectin fibre can help increase total daily fibre intake.

Fish oil may be helpful to alleviate inflammation together with nutrients such as curcumin.

Your client may find benefit in mucilage herbs. Mucilages are complex sugars found in many plants that form a thick, gel-like film when mixed with water. Psyllium seed husk, flaxseed, slippery elm and marshmallow root are examples.

When ingested, mucilages are believed to form a barrier or lining on the intestinal mucosa, protecting against infection and injury, soothing irritation, and promoting tissue healing.

Another option is colostrum which may help with support the gut barrier and modulating the immune response – clearly if the client is sensitive to dairy this may not be appropriate.

If you feel that ongoing stress is still a problem for this client, then I would focus on supporting her adrenal health in addition.


The following supplements are suggested for you to consider in light of your relevant expertise and intimate understanding of the needs of your client or patient. They may be used in isolation or as part of a multi supplement strategy, but at all times the consideration of their use should be tied into the specific needs of the individual you are responsible for.

Probiotic support

GI Flora (ARG) – take 1 twice daily – contains 4 beneficial probiotic bacteria: Lactobacillus acidophilus, L. rhamnosus, L. casei, and Bifidobacterium longum.

Saccharomyces boulardii (ARG) – take 1 at each meal (to calm bowel movements) –

Buytrate (Body Bio) – take 2 capsules with each meal (store in fridge to reduce odour)

Vitamin D3 Complete (ARG) – take 1 daily – – innate immune system support

Anti-inflammatory support

KappArest (BRC) – take 2 at each meal –

Phospholipid Colostrum (ARG) – take 1tbsp twice daily –

I hope this helps answer your question
