The most important concern for people with diabetes is how to lower their blood glucose, and whether the lower the blood glucose, the better. In the process of diabetes treatment, the following problems may occur: What is hypoglycemia? What are the dangers of hypoglycemia? The symptoms of hypoglycemia vary widely. Common clinical manifestations include sweating, hunger, salivation, trembling, palpitations, nervousness, anxiety, weakness, pallor, rapid heart rate, cold extremities, abnormal sensation, and mildly elevated systolic blood pressure. There may also be manifestations of brain dysfunction, such as mental inattention, slow thinking and speech, dizziness, drowsiness, blurred vision, unsteady gait, hallucinations, restlessness, irritability, strange behavior, and even into coma, and some even have petit or grand mal seizures. If hypoglycemia is not corrected continuously, it is often not easily reversed or even death. Generally, hypoglycemia attacks with blood sugar below 2.8mmol/L. The greatest danger of hypoglycemia is that it may induce cerebrovascular accidents and/or myocardial infarction, or even death. repeated hypoglycemia in children under 5 years old can cause permanent damage to IQ, while repeated subclinical hypoglycemia in the elderly below 4.0mmol/L can cause Alzheimer’s disease or early onset of Alzheimer’s disease. What conditions can cause hypoglycemia in diabetics? Hypoglycemia is inevitable in diabetic patients who commonly use insulin preparations, sulfonylureas and non-sulfonylurea promoters, or other classes of hypoglycemic drugs in combination with the above hypoglycemic drugs. Excessive doses of drugs, improper usage, inadequate food intake, inappropriate exercise, alcohol abuse, malnutrition, severe infections, combined use of other drugs that may enhance the hypoglycemic effect, and especially the use of chlorosulfonylurea or glibenclamide in elderly and diabetic patients with combined renal insufficiency are prone to severe, persistent and persistent hypoglycemia. In addition, those irregular proprietary Chinese medicines (which are actually western medicines inside) can also cause hypoglycemia, and even severe hypoglycemia. How to prevent and treat hypoglycemia? When using hypoglycemic drugs, it is advisable to start with small doses, monitor blood sugar closely, and gradually adjust the dose according to blood sugar changes. Different types of hypoglycemic drugs have different pharmacological properties, so it is necessary to take the drugs or inject insulin at different times according to the specific instructions of endocrinologists. If a combination of drugs that may enhance the hypoglycemic effect is required, it is recommended to consult an endocrinologist for relevant precautions and to enhance blood glucose monitoring. The use of glucose-lowering drugs in the elderly and diabetic patients with combined renal insufficiency requires more caution. If you do not eat enough or exercise too much for various reasons, the dose of medication may have to be reduced from the original one. The usual life and rest should be as regular as possible, including the time of eating, the amount of food, the time of exercise, the amount of exercise, sleep and rest should not fluctuate too much, even the mental and emotional should be kept somewhat calm, and quit alcoholism and other bad habits. For mild to moderate hypoglycemia, it can be relieved by taking sugar water and sugary drinks orally, or by eating candies, cookies, bread and steamed buns. For drug-induced hypoglycemia, the relevant drugs should be stopped in time. Those with severe or hypoglycemic coma should be sent to hospital for emergency treatment, given glucose injection intravenously or pushed, and if necessary, hydrocortisone and/or glucagon should be added. In short, to be a conscientious person in self-management of blood glucose, we can avoid blood glucose from “dropping too much” as much as possible.
