Bowel Health

The emerging science of Nutrigenomics

Bowel disease plagues many people and this ranges from irritable bowel syndrome (IBS) to the inflammatory bowel diseases (IBD) such as Crohn’s Disease and Ulcerative Colitis

Many people go through life suffering from symptoms such as abdominal pain, bloating, nausea and generally feeling unwell with constipation or diarrhoea or a mix of both problems.

Some find it difficult to tolerate many foods and simple stool testing can miss complex pathology.

The vast majority of GP’s are not trained to deal with food sensitivities or functional bowel disease beyond the pharmacological approach and yet so much can be done to investigate and treat underlying causes of symptoms that just don’t want to go away.

A detailed stool analysis that counts bacterial populations is vital as even those bacteria called commensals thought to be benign, can become pathogenic if their numbers increase to pathological levels.

Many with IBS or IBD will suffer from Small Intestinal Bacterial Overgrowth (SIBO). Can this be diagnosed and treated? You bet! It is thought that up to 80% of those with simple irritable bowel syndrome (IBS) may be suffering from small intestinal bowel overgrowth (SIBO) and this will cause a hyper-response to many foods with persistent foul smelling soft stools or diarrhoea, halitosis, coated tongue and generally feeling quite unwell. This needs a targeted by a thorough medically managed approach and it is an area that should not be dealt with by practitioners who do not have the wealth of knowledge and resources to treat this condition effectively. Many patients with Crohn's Disease or Ulcerative Colitis may have SIBO that adds to their burden of disease symptoms. 

Bowel disease including IBS if left untreated, can affect the whole body as the collective bowel flora is now known to be critical for your general health. A normal bowel flora will ensure you have a robust immune system with decreased inflammation in the body. SIBO and abnormal large bowel organisms may damage the bowel lining and increase the risk of damage to numerous organs including the heart and brain and will increase the risk for autoimmune disease by increasing intestinal permeability. 

Persistent bowel symptoms need to be assessed through breath tests for SIBO, stool PCR and haemoccult testing to detailed stool analysis, IgG food sensitivity testing, to excluding coeliac disease and FODMAP sensitivities and other problems such as histamine sensitivity. Endoscopy can exclude more serious and dangerous concerns and Calprotectin is a stool test that can identify if inflammatory bowel disease (IBD). IBD may smoulder in the background putting the individual at significant risk unless identified and treated.  

This approach is for an individual who wants a big-picture assessment of their health risks by someone with medical qualifications from a world renowned medical school who has the skills and experience to know what is and is not significant in a medical sense.
