What are the dangers of hypoglycemia?

The problem of hypoglycemia cannot be ignored, because its impact is very large. It may cause common symptoms such as hunger, dizziness, palpitations, pale complexion, cold sweats, etc. Some may also induce arrhythmia and angina pectoris.

1. Hypoglycemia hemiplegia

The mechanism of occurrence is still unclear

The occurrence mechanism of hypoglycemic hemiplegia is still unclear. It is generally believed that there are the following possibilities: most elderly people have cerebral arteriosclerosis and stenosis. When blood sugar is normal, the blood supply areas of these narrow arteries can still obtain the energy (blood sugar) necessary to maintain their normal functions. However, when hypoglycemia occurs, the excitability of the sympathetic nerves increases, causing spasm and contraction of cerebral blood vessels, resulting in an unbalanced blood supply to various parts of the brain. Those parts with relatively severe ischemia will experience functional disorders, causing hemiplegia, etc. Glucose is the main energy source for brain cell activity. Severe and persistent hypoglycemia can inhibit the cerebral cortex, cause brain dysfunction, and even coma.

2. Diabetic patients are well aware of the dangers of high blood sugar and take it very seriously, but they often do not pay enough attention to the severity of hypoglycemia. In fact, the harm of hypoglycemia is no less than that of hyperglycemia, and sometimes even more dangerous. Mild hypoglycemia can cause sympathetic nerve excitement, resulting in symptoms such as hunger, dizziness, palpitations, trembling hands, pale complexion, cold sweats, weakness, etc.; central nervous system symptoms may also occur.

3. There are usually five manifestations: 1. Changes in consciousness; 2. Abnormal behavior; 3. Dizziness and tremors; 4. Epileptic seizures; 5. Sudden hemiplegia. Not only that, hypoglycemia in the elderly can easily induce complications such as arrhythmia, angina pectoris, myocardial infarction and cerebrovascular accident, so you should be especially careful. Acute hypoglycemia can also cause cerebral edema, and long-term chronic hypoglycemia can lead to intellectual decline and accelerate the process of dementia.
