Hypoglycemia is a type of complication that often occurs during the treatment of diabetes and is a lingering psychological shadow for many diabetics. Some patients who injected insulin told me clearly that hypoglycemia is marked by palpitations, sweating, shortness of breath, and sometimes it seems that they can’t pass, and they must eat immediately. In the future, I would never dare to let the blood sugar be low again, and often eat in advance. This is a category of patients with symptoms, and there are some patients without hypoglycemic symptoms, especially some with long disease duration and cardiac vegetative nerve lesions, who may have asymptomatic hypoglycemia, and some even have coma directly. To understand the change of blood sugar in a day, doing dynamic blood sugar monitoring is undoubtedly the best way, but this monitoring method, such as doing it in the hospital, usually requires hospitalization and monitoring for three days, which is a complicated process. Thanks to the development of technology, the home use of dynamic blood glucose monitoring system has also been introduced, many patients can complete 3-7 days of blood glucose check at home, while avoiding the pain of multiple needle sticks, and more accurately understand the fluctuation of blood glucose, discover the occurrence of potential hypoglycemia, and more accurately adjust the medication. Hypoglycemia is more terrible than hyperglycemia Compared with hyperglycemia, hypoglycemia can be said to be not the most terrible, only more terrible. Due to medication, insulin injection and so on, the vast majority of sugar lovers may have encountered hypoglycemia symptoms. If hyperglycemia is the cause of the disease, it is the main cause of diabetes complications, then hypoglycemia is undoubtedly fatal. It can even be like a hidden killer sometimes, hiding in the shadows, waiting for an opportunity to strike. Compared with symptomatic hypoglycemia, asymptomatic hypoglycemia may be a bit unfamiliar to you. Simply put, asymptomatic hypoglycemia is the absence of any feeling and aura, often in the unknowing into a coma, if not handled in time, then it is likely to be life-threatening. It sounds scary, so the pro must pay attention to it. But then, we should not be overly nervous. This asymptomatic hypoglycemia mostly occurs in type 1 diabetes, elderly diabetes, hepatic and renal insufficiency and alcoholics with a long history of the disease. The only way to prevent asymptomatic hypoglycemia, which is so harmful, is to do 24-hour blood glucose monitoring in clinical practice. Nocturnal hypoglycemia should be detected early Nocturnal hypoglycemia, as the name implies, of course occurs at night, and usually occurs in sleep, often asymptomatic, and usually not easily detected by us, and this state can even be maintained for several hours without waking us up, which can seriously endanger our lives and occur sudden death. Compared with asymptomatic hypoglycemia, nighttime hypoglycemia is not as good, if not better, at hiding.
