In patients with type 1 diabetes, there is a loss of the cells which makes insulin. A majority of diabetes patients uses human insulin or insulin analogs. The human insulin is produced by bacteria or by yeast using genetic engineering.
The insulin in the body allows the sugar to pass from the blood into the cells, where it is burned for energy. The human body is not able to convert sugar into energy without insulin. Furthermore, insulin helps in turning off the making of sugar in the liver. In the absence of insulin, the sugar builds up in the blood and spills into the urine. Diabetic patients cannot make enough insulin. These patients required insulin injections to fulfill the need.
