There is no such thing as “is it serious to take 14 units of insulin a day”, and the severity of the disease cannot be judged solely on the basis of taking 14 units of insulin a day. The severity of diabetes needs to be considered in conjunction with the patient’s blood glucose and the presence or absence of related complications. The dosage of insulin needs to be adjusted according to the patient’s weight, blood glucose control and other factors, so you can’t judge the severity of the disease just by taking 14 units of insulin a day. To determine the severity of diabetes, it is necessary to combine the patient’s blood glucose control, the presence of complications and other factors for comprehensive consideration; if the blood glucose control is within a reasonable range and there are no complications such as diabetic cardiovascular disease, nephropathy, retinopathy and a series of other complications, then it is not serious; if the blood glucose control is unstable and accompanied by diabetic complications, then it is more serious. Patients diagnosed with diabetes should actively cooperate with their doctors to maintain a healthy lifestyle and diet, which will help improve the prognosis.
