How Does Diabetes Affect People?
Diabetes is a metabolic disorder in which there is increased blood glucose level. Now although there is excess of glucose in blood, the cells are not able to utilize that glucose. The cells are actually starving. Here comes the role of insulin. Insulin facilitates the intake of glucose by the cells. Almost all the cells in our body have these receptors. In diabetes mellitus there is insulin deficiency due to which cells are not able to utilize glucose. This insulin deficiency can be absolute or relative. I will not go into the details of the various causes of insulin deficiency. Let's just focus on what happens when cells cannot utilize glucose and there is excess of glucose in the blood. Excess of glucose in blood results in excess of glucose in urine. Glucose is a sugar and it produces osmotic effect due to which water and electrolytes of the urine are also increased. Hence there is polyuria along with polydypsia. If this persists the patient might go into shock. As the cells cannot utilize glucose the liver starts producing ketone bodies as a source of energy. Excessive formation of ketone bodies may lead to ketoacidosis. Long term diabetes may lead to microangiopathies like dia Continue reading >>
