Recently, the topic of "how awkward it is to have a hypoglycemic attack" has made headlines. The awkward scene made everyone laugh. However, as the most common symptom around us, hypoglycemia can be life-threatening in severe cases. How to avoid hypoglycemia? Be alert to asymptomatic hypoglycemia. What is hypoglycemia? Xie Yijun, the attending physician of the Department of Endocrinology at Guangzhou First People's Hospital, explained that hypoglycemia is a state of low blood sugar concentration caused by various reasons. When blood sugar decreases and corresponding symptoms and signs appear, it is called hypoglycemia. For non diabetes patients, blood glucose ≤ 2.8 mmol/L belongs to hypoglycemia; For patients with diabetes, blood glucose ≤ 3.9 mmol/L belongs to hypoglycemia. When hypoglycemia occurs, there may be symptoms such as palpitations, cold sweats, trembling, hunger, and even symptoms such as emotional instability and headaches. Xie Yijun pointed out that in addition to typical hypoglycemic symptoms, hypoglycemia in elderly patients can also be manifested as neuropsychiatric symptoms of decreased cerebral cortex function, such as slow response, drowsiness, unstable gait, and even hallucinations, abnormal behavior and other mental disorders, or manifested as convulsions, limb paralysis, coma, etc., which are easily misdiagnosed as cerebrovascular diseases. It is worth noting that there is also asymptomatic hypoglycemia. Xie Yijun pointed out that this type is more common in elderly patients with diabetes and patients with long-term frequent hypoglycemia. Whether diabetes patients or non diabetes patients can induce acute cardiovascular and cerebrovascular adverse events, the risk factors for hypoglycemia often include the following: not eating normally, or eating too little; Drinking heavily, especially on an empty stomach; Intense exercise, prolonged exercise, or fasting exercise. Xie Yijun stated that the above behavior will weaken the body's defense mechanism against hypoglycemia, leading to hypoglycemia. In addition, for patients with diabetes, excessive hypoglycemic drugs and mismatch between medication and meal time may also lead to hypoglycemia. Once hypoglycemia occurs, it can induce acute cardiovascular and cerebrovascular adverse events, accelerate the process of chronic complications of diabetes, and may also induce or aggravate autonomic nervous dysfunction of patients, form a vicious circle, or even die. High risk individuals can carry candy or fruit juice with them. In fact, hypoglycemia can be prevented. Xie Yijun stated that we should develop good living habits, eat three meals on time, and avoid overeating; Try to drink less alcohol, avoid drinking on an empty stomach, and exercise regularly to avoid fasting. Diabetes patients should take medicine strictly according to the doctor's advice, pay attention to the dosage, medication and meal time. Carry food that prevents hypoglycemia with you, such as candy, juice, biscuits, etc. What should I do when encountering someone else or myself experiencing hypoglycemia? Xie Yijun suggests that if the patient is in a clear state, the most ideal condition is to give the patient an oral dose of 15-20 grams of glucose to alleviate the symptoms; The second is to eat candy juice, soft drinks, milk, candy or other Dim sum. It should be noted that if a patient experiences symptoms of hypoglycemia but falls into a coma, they must immediately call the emergency phone and seek medical attention as soon as possible
