Leaky gut

Round & About

gut

We will consume between three and seven tonnes of food and drink in our lifetimes, which has to be broken down and then the nutrients absorbed across the gut barrier, before they can be utilised by the body. The size of a tennis court, the gut barrier of the small intestine is made up of a single layer of cells that not only regulate the flow of nutrients and water into the body, but also play a central role in how our immune system responds to the dietary proteins and microbes that are ingested on a daily basis.

Nothing put into the digestive system is, technically speaking, inside the body until it has been absorbed across the gut barrier. It is the gut barrier that decides what to both let in and keep out of systemic circulation.

Research shows that the integrity of the gut barrier is fundamental to health and wellbeing. If the gut barrier is compromised by ‘leaking’ between and/or through the cells (para and/or trans cellular hyperpermeability), unwanted substances might permeate through and provoke unwanted immune responses – fuelling chronic inflammation, which is the route cause of all chronic disease and is a recognised key factor in the development of autoimmunity. Some of the conditions directly associated with ‘leaky gut’ include: coeliac disease, type 1 diabetes, rheumatoid arthritis, psoriasis, spondylitis, Parkinson’s disease, endometriosis, eczema, Crohn’s disease, colitis, multiple sclerosis, chronic fatigue syndrome, depression, anxiety and schizophrenia.

Leakiness between the cells of the gut barrier is controlled dynamically by a protein called zonulin. The higher the levels of zonulin, the greater the leakiness between the cells. The zonulin pathway is initiated by either the presence of pathogenic bacteria and/or gluten in the gut. Dysbiosis (imbalances in the micro ecology of the gut) and leaky gut usually co exist.

The presence of either or both of these conditions will drive a state of chronic inflammation. Fortunately, you can repair ‘leaky gut’ and rebalance the micro ecology of the gut, regaining control of health and wellbeing.

The gut and mental health

Round & About

gut

It is not a new concept that a ‘gut brain’ axis exists and I have touched on this subject before in previous columns.

Serotonin is a neurotransmitter that regulates mood, appetite and sleep; when there are appropriate levels in the brain we feel relaxed and positive. This is the principle behind selective serotonin reuptake inhibitor drugs (SSRIs), to increase levels of serotonin available to the central nervous system. It is the gut, not the brain, however that is responsible for over 90% of total serotonin production.

In the gut, serotonin controls how ‘regular’ you are and it is the balance of the bacterial species in our gut that appears to play a significant role in the amount of serotonin produced. This might well explain not only why a significant relationship exists between individuals presenting with irritable bowel syndrome (IBS) and depression, but also why when doctors prescribe SSRIs for depression, those presenting with IBS often see improvements in digestive function.

A new study has found evidence in humans (not rodents as was the case until now) that our emotional responses, including anxiety and depression vary considerably depending on bacterial balance in the gut. The results not only suggest a strong link between the bacterial composition of our guts and feelings, but that the balance may change the physical structure of the brain by either growing the frontal cortex or shrinking the hippocampus – areas of the brain involved in problem solving, emotional regulation and consciousness. Understanding that gut microflora can play such a huge role in chemical balance of the brain is one thing, but that these microbes might initiate physical changes in the brain is another! This may well be why in clinical practice I often see clients’ overall mental health and wellbeing improve as we identify and eliminate key food and environmental sensitivities and support overall gut health.
