Type 1 diabetes can occur at any age, but is most often diagnosed early in life. Type 1 diabetes is called an autoimmune disease, because the immune system attacks the person’s own cells. In this type of diabetes, cells in the pancreas that produce insulin are the target of the body's immune system and are eventually destroyed. For this reason, people with type 1 diabetes produce no insulin so glucose cannot get into the cells.
The symptoms of type 1 diabetes all relate to the high blood glucose levels. The glucose does not keep into the cell so the cell can’t do its work. This causes weight loss and tiredness. Because the glucose can’t get into the cell, the cell also signals that it needs glucose (food) and extreme hunger results. With the high blood glucose, there is an increased excretion of glucose into the urine. This also pulls more water with the glucose to keep the urine less concentrated. These two things cause increased thirst and increased urination.
