Diabetes mellitus is a condition where your blood sugar levels are higher than normal.
This happens when there is an abnormality in insulin production or action. Insulin is the hormone that acts on different parts of the body in the utilization of glucose (sugar) present in the blood.
If insulin is low or does not function properly in the body, this will result in high blood sugar. This elevated blood sugar is called hyperglycemia.
Type 2 is the most common type of diabetes. It happens when the body is unable to properly use the insulin being produced by the pancreas because of insulin resistance.
Insulin resistance makes it difficult for the body to absorb glucose present in the blood. At first, it can be overcome by the body’s ability to produce higher levels of insulin. However, there comes a point when the body is unable to produce enough insulin, resulting in high blood sugar.
