There are many factors that affect how long a person with advanced diabetes can live, such as the size of the severity of the patient’s condition, his or her physical fitness, and whether there are other complications, etc., which is why it is not possible to make a generalization. However, if it is detected in time and actively treated, the survival rate will increase. It is important to treat diabetes as soon as possible after it develops.
