There is no such thing as how long a 30 year old with diabetes will last. If diabetes is detected at an early stage, it is possible to have the same life expectancy as a normal person after scientific and reasonable treatment. However, if diabetes is not well controlled and combined with other serious complications, the survival period may be shortened accordingly, depending on the individual’s situation. After the diagnosis of diabetes mellitus should be carried out under the guidance of a physician for the full management of diabetes mellitus, including health education, medical nutrition therapy, exercise therapy, blood glucose monitoring and medication and other comprehensive treatment means. 1. Diabetes health education is an important basic management measure, which is the key to the success or failure of diabetes management. Every diabetic patient should receive comprehensive diabetes education, fully understand diabetes and master self-management skills. 2. Medical nutrition therapy, the general principle is to determine a reasonable total energy intake, reasonable and balanced distribution of various nutrients, to restore and maintain an ideal body weight. 3. Exercise therapy, under the guidance of the physician to carry out regular and appropriate exercise, step by step, and long-term persistence. 4. Condition monitoring, including blood glucose monitoring, monitoring of other cardiovascular disease risk factors and complications. 5. Pharmacological treatment of hyperglycemia, including oral drugs and injectable preparations. When diet and exercise fail to bring blood glucose control up to the standard, glucose-lowering drugs should be applied in a timely manner. Therefore, it is recommended that diabetic patients receive systematic treatment in a timely and reasonable manner to avoid the emergence of various acute and chronic complications that may affect the quality of life and survival time, and consult the doctor in time if they feel unwell.
