The treatment of hypoglycemia mainly includes two aspects: the first is to alleviate the symptoms of hypoglycemia, and the second is to correct various underlying causes that lead to hypoglycemia. For various cases of hypoglycemia that have already occurred, rapid relief can be achieved by administering sugar water, sugary drinks, or consuming candies, cookies, bread, steamed buns, etc. If it is drug-induced hypoglycemia in diabetic patients, the relevant drugs should be discontinued promptly. If hypoglycemia occurs frequently, or even leads to coma, it is possible to investigate the primary disease, conduct a hypoglycemia test, and determine whether an insulinoma exists.

How to Treat Hypoglycemia

If the patient is experiencing symptoms such as dizziness, palpitations, cold sweats, and feelings of hunger, but is mentally clear, it is suggested to promptly eat foods like candy or chocolate that can rapidly increase blood sugar levels. However, if the patient's hypoglycemia isn’t fully corrected and leads to unconsciousness, then it is critical to immediately call emergency services (dial 120). Upon their arrival, a micro blood sugar test should be conducted. Secondly, an injection of 50% glucose can be administered intravenously to correct the hypoglycemia. Thus, preventing hypoglycemia is very important.

The harms of hypoglycemia

Hypoglycemia poses significant risks to the human body and mainly includes the following aspects: Firstly, hypoglycemia can lead to brain dysfunction, initially characterized by lack of mental focus, sluggish thinking and speech, dizziness, drowsiness, irritability, and other symptoms. In later stages, seizures, coma, and even death may occur. Secondly, recurrent hypoglycemic episodes can cause irreversible damage to the central nervous system, leading to changes in personality, mental disorders, dementia, etc. Thirdly, hypoglycemia can stimulate the cardiovascular system, trigger arrhythmias, myocardial infarction, and so on. Fourthly, prolonged hypoglycemic coma, if unnoticed, can result in death.

What are the symptoms of hypoglycemia?

The symptoms of hypoglycemia primarily manifest as signs of sympathetic nervous excitement and lack of oxygen in brain cells. Sympathetic nervous excitement can cause feelings of hunger, pale complexion, palpitations, dizziness, and trembling limbs. Meanwhile, the lack of oxygen in brain cells primarily presents as disturbances in neurological functions. The most common symptoms include inability to concentrate, slow speech and thought processes, drowsiness, abnormal behavior, and in severe cases, it can even lead to coma.

How to test for hypoglycemia?

Hypoglycemia refers to a syndrome characterized by symptoms of sympathetic nerve excitation and brain cell hypoxia due to low blood glucose concentration. We usually identify hypoglycemia first by a series of symptoms. The primary symptoms of hypoglycemia are sympathetic nerve symptoms, including dizziness, palpitations, cold sweats, hunger, and pallor. If these symptoms occur, we use a glucometer to determine if the blood sugar level is below 2.8 mmol/L. If the blood sugar is below 2.8 mmol/L, one should quickly consume sugary water and energy. If the patient's symptoms are alleviated, then it is considered hypoglycemia.

How to treat hypoglycemia?

First, we need to accurately identify what hypoglycemia is. We often judge the occurrence of hypoglycemia based on symptoms, such as common symptoms including palpitations, dizziness, pale complexion, general weakness, trembling limbs, sweating, etc. When these symptoms appear, we should immediately use a rapid glucose meter to measure the fingertip blood sugar. If the blood sugar is below 2.8, then the diagnosis of hypoglycemia is confirmed. We immediately provide sugary drinks or other forms of energy substances, and the symptoms of low blood sugar can be greatly relieved.
