There are various forms of diabetes but the most common type is diabetes mellitus which is also known as ‘sugar diabetes’. This disease affects the body’s system for regulating the level of sugar or glucose in the bloodstream. The main hormone that is involved in this system is insulin which is secreted by the pancreas, and this acts to reduce the level of glucose in the blood by encouraging the uptake of sugar into the cells of the body where it is stored or used for energy.
In diabetic animals the most common type of problem is the pancreas failing to produce sufficient insulin (the equivalent of type 1 diabetes in people). This then leads to elevated levels of glucose in the bloodstream as there is not enough insulin to maintain the glucose at the correct level.
