Why is it said that low blood sugar is more deadly than high blood sugar?
2024-01-09
We often hear a saying: high blood sugar costs money, low blood sugar costs life. This statement is not without reason, it succinctly points out that low blood sugar has a great impact on health. Hypoglycemia is essentially a condition where blood sugar levels are lower than normal due to various reasons, leading to symptoms such as excessive excitation of the autonomic sympathetic nervous system and neurological dysfunction. Compared to the persistent high blood sugar, low blood sugar is often more rapid and more likely to cause serious consequences in a short period of time. The three major causes of hypoglycemia are iatrogenic hypoglycemia. Some elderly patients with diabetes have poor compliance, failed to monitor blood sugar regularly, and did not adjust the dosage of hypoglycemic drugs or insulin in time, leading to excessive hypoglycemic. In addition, the organ function of elderly patients has decreased, and they even suffer from multiple diseases. They need to take a large amount of medication every day, and some non hypoglycemic drugs have also played a role in lowering blood sugar. Eating too little and consuming too much can also easily lead to hypoglycemia, such as due to old age, weakness, difficulty swallowing, or anorexia. Consuming too little, exercising for too long, or heavy physical labor can cause excessive consumption. Excessive alcohol consumption on an empty stomach may also lead to severe hypoglycemia. Liver and kidney diseases can affect the body's gluconeogenesis, hinder the conversion of non sugar substances into glucose, disrupt normal glucose metabolism, and ultimately lead to low blood sugar levels. What are the symptoms of hypoglycemia? A severe hypoglycemia and the resulting physical harm can offset the benefits of controlling high blood sugar for a lifetime. Therefore, it is crucial to quickly identify and detect hypoglycemia and handle it in a timely manner. The normal value of blood sugar on an empty stomach is 3.9-6.1 mmol/L. For non diabetes patients, blood glucose ≤ 2.8mmol/L belongs to hypoglycemia; For patients with diabetes, blood glucose ≤ 3.9mmol/L belongs to hypoglycemia. The human body has varying degrees of response to a decrease in blood sugar, and generally does not wait until blood sugar drops below normal levels before issuing an alarm. Usually, when blood sugar drops to 4.6mmol/L, people will feel "hungry" and remind us to eat quickly; When blood sugar further drops below 3.9 mmol/L, some people begin to experience a series of symptoms of sympathetic nervous system excitement, such as palpitations, tremors, nervousness, sweating, and pale complexion; When blood sugar drops below 2.8mmol/L, brain cells begin to be damaged due to insufficient energy supply, resulting in symptoms such as dizziness, headache, unclear consciousness, and coma. If energy cannot be replenished in a timely manner to increase blood sugar, it will be very dangerous. Once diagnosed with hypoglycemia, it is important to consume sugary foods in a timely manner to increase blood sugar levels and avoid danger. Sugar, sugar cubes, honey, and glucose tablets are more easily absorbed into the bloodstream by the intestines and can raise blood sugar levels in a shorter period of time; Secondly, you can choose biscuits, Mantou, sugary drinks, white rice Congee, etc; Milk, ice cream, and other raw sugars are relatively slow. After 15 minutes, the symptoms still did not improve, and the blood sugar level was measured to be below 3.9 mmol/L. It can be taken repeatedly. If the patient's hypoglycemia has improved to some extent and the blood sugar level has exceeded 3.9 mmol/L (more than 1 hour from the next eating time), it is recommended to give food containing starch or protein
