An Approximate of 41 million people which makes up for more than 70% of the deaths annually are caused by non-communicable diseases like cancer, cardiovascular diseases, diabetes, respiratory diseases, and other chronic diseases. Bacteria, fungi or viruses play no significant role in the rise of communicable diseases. This has been challenged by scientists who dig deeper into researching the effect of the microbiome (collection of microbes crawling in and on the body) on our health. It was found that diabetics and those with inflammatory bowel disease and heart disease host a different set of microbiome than those who do not have these diseases.

For the purpose of this study saliva and stool samples were collected of about 290 people living within a close range of each other. Results showed that mothers and their kids had many similar microbes and the microbiomes of the spouses matched with a lot of similarities. Further, it was seen that the diagnosis of diabetes or irritable bowel syndrome of one spouse increased the chances of their partner being diagnosed with the same disease. Even having an obese family or friends or coming from a country that is majorly obese makes one more prone to obesity.

The results are not conclusive as more evidence is required to show which aspects of the disease is linked to microbes. Another area of study would be to understand how in-house bacteria affect the health of a human. If this research is thrown more light on it could highlight groundbreaking facts on the comprehension of non-communicable diseases.
