The disease is divided into the first and second types.
In type 2 diabetes, the body’s cells are less sensitive to insulin, so they do not accept the glucose it carries and it remains in the blood in excess. Or, for some reason, insulin stops effectively regulating glucose production in the liver, so blood sugar levels rise.
In insulin-dependent type 1 diabetes, the body’s own immune system destroys the pancreatic cells responsible for producing insulin. Therefore, insulin does not enter the blood and does not transfer glucose to the cells, which remains in the blood. This condition requires the introduction of insulin into the body through injections, which is why the first type is called insulin-dependent diabetes mellitus.
