The connection between diabetes and inflammatory bowel disease

Type 1 diabetes and autoimmune conditions

If you live with type 1 diabetes you are at a higher risk of developing other autoimmune conditions such as inflammatory bowel disease (Crohn’s disease or ulcerative colitis) and coeliac disease. People who have already developed autoimmune conditions are also at higher risk of developing type 1 diabetes.

Why are we interested? The more we can understand about the genetics of type 1 diabetes and autoimmune conditions, the closer we get to new treatments and potential cure or prevention methods.

Type 2 diabetes and connection with gut issues

Research shows chronic intestinal inflammation common in inflammatory bowel disease (Crohn’s disease and ulcerative colitis) appears to increase the risk of a person developing type 2 diabetes.

The gut plays a big part in regulating glucose levels. Studies are now looking at how inflammatory bowel disease might impact the development of diabetes.

Besides digestion and nutrient absorption, the gut is involved in modulating the immune system, secreting hormones and signalling nerves. It is also home to billions of microbes and microflora (the microbiome).

Researchers have explored the long-term risk for people living with type 2 diabetes developing inflammatory bowel disease, or vice versa, by looking at population-based studies.

While there is still a large amount of debate surrounding the basic relationship between inflammatory bowel disease and diabetes, it is thought the mechanism of chronic inflammation and genetic factors common to type 1 and type 2 diabetes and inflammatory bowel disease may play a role in this. One explanation for the relationship between inflammatory bowel disease and diabetes is that inflammatory bowel disease is associated with diabetes due to chronic inflammation and dysbiosis – an abnormal gut microbiome.

It has been suggested that products from the gut microbiome may interact with the immune system inducing a tissue metabolic modification, which feeds the low-grade inflammation that occurs in the onset of both overweight and type 2 diabetes.

What can we do about this?

The current medications for both type 1 and type 2 diabetes have anti-inflammatory properties in addition to their major modes of action. Lifestyle changes also appear to reduce inflammation and improve cardiovascular health.

Improve your gut microbiome by:

  • Eating plenty of fibre: wholegrains, fruit, vegetables including legumes, nuts
  • Including probiotics (good bacteria) in your diet: probiotic yoghurt or probiotic yoghurt drinks

As well as:

  • Exercising regularly
  • Taking medications, as prescribed.
