The pancreas secreted a substance called insulin when the sugar level in someone’s blood increased after eating. It circulated the body through the blood vessels and ordered cells to digest the sugar. Then, the cells would absorb the sugar in the blood and blood sugar levels would go down as a result.0

In diabetes mellitus, a state of high blood sugar continued because this system was broken. The term diabetes mellitus was derived from Latin, diabetes meaning discharge and mellitus meaning honey sweet, describing the sweet urine produced when the excess sugar in the body is excreted through urine.[1]0

Type 1 diabetes was when insulin wasn’t secreted even when blood sugar levels were high, and type 2 diabetes was when insulin was secreted, but certain cells around the body did not listen. It was called insulin resistance. The molecular biology of the cause of insulin resistance was yet to be discovered… Until now.0

‘Now I know the reason.’0

Rosaline showed Young-Joon. This was related to an immune response.0

The immune system was usually soldiers of the body that existed to destroy invading enemies like viruses or bacteria. But they malfunctioned in some people’s bodies. Some of these immune cells had gone crazy and invaded allies like fat tissue, muscles, liver, and even the bone to cut off the insulin signal by holding a knife to the throats of cells in those tissues. This was the cause of type 2 diabetes.1

Then how did intestinal microorganisms like Clorotonis or Akkermansia suppress diabetes? It was because they were not human cells, but bacteria; they were...0
