Gut has feelings lecture at king's college

Do we understand or listen our gut enough? Shall we give our Gut 5 min of our time and go through this article in order to understand how our Gut is feeling?

Last year I was invited for the first time to give a lecture at King's College in the IBS course. Due the great feedbacks, I was invited again this year for this class.

On June 6th of this year, I was again present there to give an interesting lecture about The importance of Exercise and Nutrition on controlling inflammatory bowel syndrome (IBS) condition. This course is designed for nutrition students, registered dietitians and gastrointestinal specialist doctors who currently manage, or are keen to develop knowledge in managing, patients by learning new techniques and exercise as treatment.

My participation brings more insight on different natural antibiotic and parasites treatments. Also about certain bacterias and parasites that can cause IBS in a long run or make the treatment very difficult. Also how specific exercises can help patients to decrease the stress in the Gut. I took the time to summarise all the articles and sources of information used for my lecture to put it in this article.

Although the benefits of exercise are well documented for both adults and children, new research has demonstrated that exercise in the early years of development has a significant impact on the diversity of your gut microbiome.

This diversity of bacteria has an impact on everything from your metabolism to your emotional health. I believe that as scientists continue to study the balance of bacteria in the gut, they will find it has an impact on almost every bodily system and plays a role in most illnesses or diseases.

IBS Background

IBS occurs in 10-20% of the population in the UK, but prevalence is thought to be higher than this as many people with the disorder do not seek medical advice.

Irritable bowel syndrome (IBS) is a relapsing functional bowel disorder in which abdominal pain or discomfort is associated with defecation or a change in bowel habit. Bloating and distension are often associated

IBS has a significant negative impact on quality of life and social functioning in many patients, but it is not associated with the development of serious disease or with excess mortality. IBS is associated with increased levels of psychiatric distress and poor coping strategies.

Do you want to find out if you have IBS?

Accordant to National Institute for Health and Care Excellence (NICE) positive diagnostic criteria for IBS:

Patients must give at least a six-month history of either:

  • Abdominal pain or discomfort.

  • Bloating.

  • Change in bowel habit.

Consider positively diagnosing IBS only if abdominal pain is either relieved by defecation, or associated with altered bowel frequency or stool form;

AND at least 2 of the following are present:

  • Altered passage of stool (straining, urgency, incomplete evacuation).

  • Abdominal bloating (women >men), distention tension or hardness.

  • Symptoms aggravated by eating.

  • Passage of mucus rectally.

  • Lethargy,

  • Nausea,

  • Backache

PS: Bladder symptoms may be used to support diagnosis.

You can test it using a stool test directly via a laboratorium such as this one here in the Netherlands:

Food Protocols

General dietary advice
  • Drink plenty of fluids (at least eight cups per day) but restrict tea/coffee to three cups or so per day.

  • Reduce intake of alcohol and fizzy drinks.

  • Consider limiting high-fibre foods (eg, wholemeal flour or bran), and resistant starches (often in processed or recooked foods, and fresh fruits - limit to three portions per day).

  • For diarrhoea - avoid sorbitol.

  • For wind - consider increasing oats and linseeds (one tablespoon/day).


Review fibre intake and adjust this in line with symptoms. Those with constipation as a predominant symptom may need to increase fibre intake, whereas those with diarrhoea may find the opposite helpful.

The results of the most recent meta-analyses of the benefits of soluble and insoluble fibre for IBS contradict each other. A Cochrane review found no benefit for either. Another review, however, found a benefit for soluble fibre, as ispaghula.

Fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs)

Recently there has been interest in the role of FODMAPs in causing symptoms of IBS.

Foods high in FODMAPs, such as apples, cherries, peaches, nectarines, artificial sweeteners, most lactose-containing foods, legumes, and many green vegetables (broccoli, Brussels sprouts, cabbage, and peas) may have fermentation and osmotic effects, increasing symptoms.

Diets low in FODMAPs have therefore been advocated in helping symptoms. There is evidence to support this approach. Up to 86% of people with IBS are said to report an improvement in symptoms, specifically bloating, abdominal pain, flatus and altered bowel habit, when using a low-FODMAP diet.


For those who find diet plays a significant role in their symptoms, referral to a dietician may be helpful for advice about exclusion protocol, etc.


There is some evidence for probiotics being helpful in alleviating symptoms of IBS, but further studies are needed to make more specific recommendations about optimal regimes and products. NICE guidelines suggest if used, they should be taken for four weeks at the dose recommended by the manufacturer, while monitoring the effect.
