Question

We can take the approach of understanding diabetes beginning with the most severe pathology and working backwards toward the root cause.That is not to say that we arrived at the root cause since such an origin is not known. However, as best you can, construct a sequence of events in the other direction. That is, describe the earliest events in type 2 diabetes mellitus and how those lead to successive events that lead to the most severe pathologies. Your description may have forks in the road instead of being linear. That is fine. Please be clear about where the forks are and be sure to explain the mechanism in detail.

Answer 1

Diabetes term refers to the group of diseases that cause elevated levels of sugar in the blood. There are two types of diabetes. They are type 1 and type2.
The type 1 diabetes is the condition, wherein the pancreas produces low amount of insulin, which causes the rise in the levels of blood sugar.
The type 2 diabetes is the condition, wherein the body becomes resistant to insulin. This results in the rise in the blood sugar.
Type 2 diabetes results due to the abnormal physiological functions. Abnormal physiological functions are the result of various other causes. They are obesity, poor physical activity, genetic and environmental factors.
The development of type 2 diabetes will be initiated by improper lifestyle. Improper lifestyle includes irregular sleep wake cycle, poor or negligible physical activity, over eating, smoking, exposure to polluted air, water etc
The above habits make the person to suffer with physiological sluggishness. This results in the obesity, fatigue like characters.
The above sequence of events associated with certain genetic factors will make the body of the person unresponsive or resistant to insulin and the person will suffer from type2 diabetes.
Type 2 diabetes persons are more prone to suffer with many pathogenic infections, due to poor immune system, which in turn results due to low energy levels.
The above condition results in organ failure like kidney damage, liver dysfunction etc.
