There are important differences between type 1 and type 2 diabetes. They happen in people of different ages and present differently. Type 1 diabetes is found in younger people and is because your body has stopped making insulin. This means that the glucose, that is the sugar, in your blood increases because the hormone insulin isn't there to reduce it. These individuals tend to be thin and will notice that they have been urinating a lot and have been feeling thirsty. They are treated with insulin injections. However, type 2 diabetes is probably the one you are more familiar with. It is the diabetes seen in those who are overweight. These people have insulin but because of the increased use of it due to their diet and the need to reduce the high levels of sugar they are consuming, their cells stop responding to it. These people are treated by changing their diets and sometimes even put on some medication.
