There is no set value for how long you can live with diabetes type 2, and it is related to genetic factors as well as the patient’s overall physical condition. Everyone has a different life expectancy due to genetic factors as well as acquired living conditions. If the patient’s diabetes is well controlled and there are no other serious complications, a normal life expectancy can usually be achieved. If the patient’s diabetes is poorly controlled, and the blood glucose is persistently elevated or fluctuates too much repeatedly, the patient is prone to damage to other organs, resulting in a decline in the patient’s overall physical condition, and the patient’s life expectancy will be appropriately shortened. If the patient’s blood glucose is too high, or if diabetes induces other serious complications such as severe infections, the patient’s life expectancy may be significantly shortened. Patients with type 2 diabetes are advised to seek timely medical attention, follow the doctor’s instructions and actively control their blood glucose.
