Guy: This a great post by Tania as we focus on The Month Of The Gut. If you are wondering what the relationship is to the gut, weight loss and overall health then this is a must read. I’ll be having the gut test Tania talks about in this post… In the mean time, enjoy! Over to Tania…
Tania: If you have been struggling with your weight loss plan, most of your attention will be on the food you eat and increasing your exercise – which is great, but there are some people who despite their best efforts are still unable to lose weight. Does this sound familiar and why is this the case? A growing amount of research has identified the link between an imbalance of bacteria in the digestive system regarding weight gain, metabolic syndrome and obesity.
Some gut bacteria facts
Did you know there are more bacterial cells (called microflora) in your digestive system than there are cells in your entire body! In fact, gut colonies of microflora numbers into the trillions. Many bacterial strains play in important symbiotic role in the body and help to keep us healthy. So it’s no wonder that when the delicate balance between ‘good’ bacteria and ‘bad’ bacteria in the digestive system gets disrupted our health is affected.
An overgrowth of bad bacteria in the digestive system is known as dysbiosis and is quite common, so common in fact that between 70-80% of all patients tested in our clinic prove positive. We make a point of testing every patient for this condition as it is well recognized that dysbiosis can cause low grade gut inflammation, poor digestion and nutrient absorption and can interfere with the way the body excretes hormones. This is particularly important for women as it can lead to ‘recycling’ of oestrogens, which can cause estrogen dominance and have a significant detrimental effect on hormone balance.
The latest research, released by scientist from the Cornell University in America has identified a link between dysbiosis and Metabolic Syndrome in animal studies. This group of scientist became interested in the relationship between gut bacteria and weight gain when they noticed that lab mice lacking a certain protein and had more gut bacteria than other mice and were about 15% heavier. It was found that these mice had a higher level of inflammation. Inflammatory signaling is known to promote a condition called Metabolic Syndrome which leads to weight gain, high blood pressure and cholesterol and leads to a higher risk of developing diabetes and heart disease.
The mice in this study were lacking a special protein in the cells of their digestive system which helps to control bacterial levels in the gut, this caused them to develop an overgrowth of gut bacteria. The study found that the overgrowth of bacteria in the gut triggered an inflammatory state as the cells in the digestive tract tried to respond to the bacteria. As these cells are busy trying to deal with the bacteria they are less likely to to take up glucose and process it effectively, this desensitization of the cells then leads to blood sugar fluctuations and symptoms of Metabolic Syndrome, namely weight gain, high cholesterol levels and elevated blood pressure. This was then confirmed by transferring bacterial gut populations to other mice who then developed the same symptoms.
So what causes bad bacteria in the gut?
There are several causes of bacterial overgrowth in humans including the use of antibiotics and other medications, a highly refined, high sugar diet and cleaner water and improved sanitation and hygiene in general is needed – no wonder it is so common!
Studies like this highlight the importance of having a healthy balance of digestive bacteria and the potential long term effects on overall health. This area of research has attracted a great deal of great interest in the scientific community and we can expect further studies in the future.
If you would like to be tested for dysbiosis please make an appointment to see us here. This simple urine test, that we perform on the spot, gives us accurate information on the balance of bacteria in your digestive tract. If you do have dysbiosis, it is easily treated and can be of great benefit to your health, especially if you are trying to lose weight.
