Gut bacteria linked to the development of type 2 diabetes

Print Friendly

gut-bacteria(NaturalHealth365) The intestinal environment plays a larger role in bodily function and health than just digesting food. Immunity begins in the gut and any decreases in health-promoting microbes can negatively impact the body’s immune system and therefore, the body’s ability to ward off disease.

But research now shows that gut bacteria can also provide clues as to whether or not type 2 diabetes is present. In fact, changes in intestinal microbes are often detected before other symptoms of type 2 diabetes have even emerged.

Unhealthy gut microbes linked to the development of diabetes

According to the World Health Organization and Centers for Disease Control and Prevention, approximately 285 million people worldwide and about 21 million in the United States (alone) suffer from type 2 diabetes. U.S. numbers have steadily climbed in recent years to 9.3 percent of the population, a three-fold increase in the last 30 years.

In type 2 diabetes, cells are no longer able to respond to insulin – the hormone that controls the uptake of glucose – so glucose is no longer absorbed. Even with adequate nutrition supplying glucose to the blood, cells don’t receive the energy they need.

That search has recently led scientists to theorize there may be a link between type 2 diabetes and the composition of the intestinal microbial community. Recently, four Russian researchers studied differences in the changes in the microbes of the large intestine, reporting their findings in the journal Endocrinology Connections.

In the study, gut microbial composition and glucose level were analyzed in 92 patients including 20 with type 2 diabetes and 48 healthy subjects without any chronic disease. An additional 24 subjects showed signs of pre-diabetes.

The scientists compared the composition of intestinal microbes among the three groups of study participants – diabetes, pre-diabetes and normal glucose tolerance – as well as differences in diet. In doing so, they were able to link the level of glucose intolerance with the presence of three types of microbiota: Blautia, Serratia and Akkermansia bacteria. While all three are found in healthy people, their numbers are greatly increased where diabetes is present.

The scientists concluded that one possible cause and effect between intestinal bacteria and diabetes is that certain bacteria incite an immune response. Within the intestinal bacteria population, there are microbes that form toxins that enter the gut and then cause inflammation throughout the body, including liver and fat cells that can affect overall metabolism and insulin sensitivity.

In a related study, researchers at the University of Copenhagen and the Beijing Genomics Institute analyzed about 60,000 bacterial markers in two groups of subjects, those showing signs of type 2 diabetes and those without symptoms of type 2 diabetes. Their results showed people with type 2 diabetes have different gut bacteria than those without diabetes.

This connection between diabetes and gut microbe populations should come as no surprise. Intestinal bacteria in people suffering from such conditions as obesity, rheumatoid arthritis, mood disorders, asthma, and inflammatory and irritable bowel disease have also been shown to differ from that of healthy individuals.

Promote healthy intestinal flora to avoid diabetes

Research has also demonstrated that supplementing with certain probiotic strains can have positive effects on insulin sensitivity. This underscores the need to nurture healthy gut bacteria.

Consider taking probiotic supplements to improve gut health. Of course, a healthy (clean) diet is essential. Generally speaking, healthy fats and high-fiber foods have been linked to a balanced, diverse microbial population.

Eat plenty of fiber-rich fruits and vegetables, including onions, bananas, whole grains, artichokes, and garlic – which act as prebiotics and are especially effective in stimulating healthy bacteria. Naturally, don’t forget, fermented foods such as yogurt, miso, sauerkraut, kefier, kimchi, and pickled vegetables that contain live bacteria and probiotics to improve gut health.

It is also extremely important to avoid antibiotic use, (as much as possible) which has been proven to have a negative impact on the intestinal environment.

    Type 2 diabetes is caused by a high sugar and processed food diet, which is also known to change the bacteria in the gut. The cure for diabetes is the right diet. Improved gut bacteria comes from a good diet.

    Healing your gut will bring on better health. The saying heal your gut, heal your life has a powerful message. The gut is overlooked as the cause of many problems including Alzheimer’s like symptoms.

    Gut problems are associated with schizophrenia, depression, confusion, memory problems, and epileptic-like seizures. The immune system is only working properly if the the gut is healthy.

    Abnormal gut flora makes you prone to attacks of e-coli and other food poisoning microbes, which do not usually affect a person with a healthy gut.

    Without the right bacteria digestion and assimilation of nutrients will not occur in an optimal fashion. The new RX for diabetes may just be a healed gut. I wouldn’t be surprised if all the so called “non-curable” health problems had one cause a toxic gut.

    People using modern medical treatments for diabetes are not treating the cause. There are no real shortcuts, only doctors giving drugs and patients on them think there is.

    By taking prescriptive drugs and not doing anything else you can’t reverse this condition. I have had quite a few friends who ate whatever they wanted and took their medications. They just keep getting more complications from the diabetes.

    There are some conditions, which can only be corrected naturally with dietary and other lifestyle changes, type 2 diabetes is one of these.

    What has been found and known for many years is that the medications for diabetes makes the pancreas work less efficiently. The drugs signal to this organ that it doesn’t need to regulate the sugar level. The drug will do it and at the same time effectively cause the organ to work less.

    That is one of the reasons type 2 diabetes keeps progressing. All medical treatments for this condition are aimed at control with no attention at all to the cause.

    Thanks for a wonderful article on an overlooked cause of type 2 diabetes and some really good dietary suggestions.
