Cause And Symptoms Of Diabetes Mellitus

Cause And Symptoms Of Diabetes Mellitus

Diabetes is a metabolic disorder, which in this century is commonly heard among many people. Researches have done on diabetic patients show a strong inheritance of this disease over many generations.
Diabetes is no longer a dreaded disease; a well-managed diabetic has a good life expectancy. Neglect, on other hand produces irreparable damage to arteries over the years. It is said that there is no disease, which provokes greater thought on diet than diabetes.

What is Diabetes mellitus?
Diabetes is a disorder that affects the way your body uses food for energy. Normally, the sugar you take in is digested and broken down to a simple sugar, known as glucose. The glucose then circulates in your blood where it waits to enter cells to be used as fuel. Insulin, a hormone produced by the pancreas, helps move the glucose into cells. A healthy pancreas adjusts the amount of insulin based on the level of glucose. But, if you have diabetes, this process breaks down, and blood sugar levels become too high.

There are two main types of full-blown diabetes. People with Type 1 diabetes are completely unable to produce insulin. People with Type 2 diabetes can produce insulin, but their cells don't respond to it. In either case, the glucose can't move into the cells and blood glucose levels can become high. Over time, these high glucose levels can cause serious complications.

Insulin Resistance. Insulin is necessary for the transport of blood glucose (sugar) into the cells of muscle and fat (which is then used for energy). By transporting glucose into cells, insulin keeps the blood glucose levels in the normal range. Insulin resistance (IR) is the condition whereby the effectiveness of insulin in transporting glucose (sugar) into cells is diminished. Fat cells are more insulin resistant than muscle cells; therefore, one important cause of IR is obesity. The pancreas initially responds to IR by producing more insulin. As long as the pancreas can produce enough insulin to overcome this resistance, blood glucose levels remain normal.

This IR state (characterized by normal blood glucose levels and high insulin levels) can last years. Once the pancreas can no longer keep up with producing high levels of insulin, blood glucose levels begin to rise, resulting in type 2 diabetes, thus IR is a pre-diabetes condition. In fact scientists now believe that the arteriosclerosis (hardening of the arteries) associated with diabetes likely develops during this IR period.

In diabetes, a person suffered from high blood sugar, either the body does not produce insulin or the body cells stops to respond to the insulin produced. Diabetes 3d animation can help a lot to spread awareness among people so that they can get prevented before the problem targets them.
