Why do I need to be hospitalized when I first find out about diabetes? First of all, it is important to understand that doctors do not require every new diabetic to be hospitalized, as that would mean that too many people would be hospitalized. Secondly, your diabetes is newly discovered but probably not newly acquired. So the first question that needs to be addressed is which newly diagnosed diabetics need to be hospitalized. Generally we hospitalize diabetics with fasting glucose above 11 mmol/L or glycated hemoglobin above 9%. Next why do these patients need to be hospitalized. First of all, we need to know that normal blood glucose is <6.1mmol/L fasting and <7.8mmol/L 2 hours after meal, so if the patient's fasting blood glucose has exceeded 11mmol/L, it means that the patient's blood glucose has been elevated for a short period of time, at least 3-5 years of history of elevated blood glucose, not "just got it" as the patient said. "(unless the patient is type 1 diabetic and will have elevated blood glucose in a short period of time). In addition the patient's glycated hemoglobin is over 9%, meaning that the patient's average blood sugar for the last 3 months will be above 12 mmol/L. At this blood glucose level, the patient's pancreatic islet function is very poor, and his own insulin secretion is very little. At this time, the effect of using oral hypoglycemic drugs to lower sugar is poor, and short-term intensive treatment with insulin is needed to make blood sugar drop gradually and smoothly and promote the recovery of own islet function, and then switch to oral drug treatment afterwards. This kind of treatment can protect and restore the function of pancreatic islets to the greatest extent, and it is also the treatment plan promoted in the field of endocrinology. Insulin treatment, on the other hand, is much more complicated than oral hypoglycemic drugs, involving frequent monitoring of blood glucose, adjustment of insulin dose, and attention to avoid hypoglycemia. This is not easy to do in an outpatient clinic. In addition, the treatment of diabetes does not only rely on medication, but also on the "five horsemen", of which medication is only one fifth, in addition to diet, exercise, blood glucose monitoring and diabetes education. Patients often have some misconceptions about how to eat and how to do exercise, which need to be repeatedly asked and emphasized by doctors during each checkup in order to do a good job. The knowledge about diabetes needs to be repeatedly taught by doctors, and some misconceptions of patients need to be repeatedly corrected by doctors in order to gradually change patients' understanding of the disease and to make them better cooperate with treatment. Some diabetic patients have been prescribed medication in outpatient clinics for a long time, but when asked how their blood sugar is controlled, the answer is often that they have not measured their blood sugar, or their blood sugar is not well controlled. This kind of treatment can be said to be an ineffective treatment. The most pestering aspect of diabetes is the chronic complications, and the appearance of chronic complications is even more silent. Therefore, every newly discovered type 2 diabetes should be screened for chronic complications in order to detect the first signs of chronic complications at an early stage, intervene early and prevent the aggravation of the disease. And screening for these complications is also best done during hospitalization, unless the patient is not at all poorly. So to summarize why newly discovered diabetic patients should be hospitalized: 1. For better control of blood glucose and to protect islet function. 2. for early detection of chronic complications and early diagnosis and treatment. 3. most importantly, to teach patients about diabetes so that they can self-manage their diabetes long after discharge.
