We are all familiar with “hypoglycemia”. Almost every diabetic patient has experienced hypoglycemia. It is a frequent occurrence in the process of diabetes treatment. an emergency. Compared with hyperglycemia, the harm of hypoglycemia is even greater. The harm caused by a severe hypoglycemia is enough to offset the full benefit of controlling hyperglycemia for a lifetime.
About low blood sugar, Tangtang has compiled the following knowledge points, hoping to help everyone.
Hypoglycemia standards indicate whether there is a standard for everyone< /span>
The normal healthy person’s fasting blood glucose is generally 3.9-6.1mmol/L, and the blood glucose 2 hours after a meal is ≤7.8mmol/L. diabetic patientsblood sugar <3.9mmol/L can be diagnosed as hypoglycemia; but for non-diabetic patients, blood sugar <2.8mmol/L, can be diagnosed as hypoglycemia.
The reason why the diagnostic criteria of hypoglycemia between the two are different is that normal people have sufficient glycogen reserves, while diabetic patients due to lack of insulin, lead to sugar in the body. The original reserve is insufficient, the ability to resist hypoglycemia is poor, and severe hypoglycemia is more likely to occur.
” hypoglycemia response What’s going on
In most cases, the severity of hypoglycemia symptoms such as hunger, palpitation, and sweating is basically the same as the patient’s blood sugar level , but there are exceptions. In clinical practice, when some diabetic patients have hypoglycemia symptoms such as palpitation and hunger, the immediate blood sugar test results are not low. We call this situation “hypoglycemic response”.
“Hypoglycemic reaction” is mainly seen in diabetic patients during treatment, mainly It is related to the increase in the release of glucocorticoids (such as catecholamines, etc.) caused by the rapid drop in blood sugar in a short period of time. Although the blood sugar has not yet reached the diagnostic criteria for hypoglycemia, it is difficult for the patient to adapt for a while, resulting in discomfort symptoms.
Due to insufficient insulin secretion and insulin resistance in people with diabetes, glucose in blood cannot be transported into cells for use by the body. Not low or even high, but due to the lack of glucose in the cells, the patient will still feel hungry. Another point: many patients, including some grassroots doctors, are not clear about the diagnostic criteria for hypoglycemia. They mistakenly believe that only when the blood sugar is less than or equal to 2.8mmol/L can be diagnosed as hypoglycemia and need to be treated. In fact, the above criteria are aimed at non-diabetic patients. . For diabetic patients, as long as the blood sugar is ≤3.9mmol/L, it can be diagnosed as hypoglycemia and needs to be dealt with in time.

Is hypoglycemia a thing?
Hypoglycemia is a purely biochemical indicator, not related to patient symptoms, as long as blood glucose results When the diagnostic criteria for hypoglycemia are met, hypoglycemia can be diagnosed. If the patient meets the diagnostic criteria for hypoglycemia and is accompanied by symptoms of hypoglycemia (such as palpitation, sweating, tremor, hunger, etc.), we call it “hypoglycemia”; if there are no obvious symptoms, we call it “hypoglycemia” It is called “asymptomatic hypoglycemia”. In addition, there are some patients, although the blood sugar is not low (does not meet the low blood sugar standard), but has symptoms of hypoglycemia such as hunger, palpitation, tremor, sweating, etc., which we call “low blood sugar”. Blood Glucose Response”.
What Diabetics Are Likely to Happen to Hypoglycemia
Some diabetics feel overwhelmed after drinking some alcohol, with symptoms such as dizziness and fatigue. Many patients think that they are drunk, but this is not the case. Blood sugar symptoms appear.
Generally speaking, under normal circumstances, alcohol will be metabolized into ethanol after entering the body’s liver. When ethanol is absorbed into the human blood, it will stimulate the pancreas to secrete a large amount of insulin. At this time, a large amount of insulin is secreted, which will reduce the blood sugar concentration. At the same time, ethanol quickly enters the liver and inhibits the decomposition of liver glycogen, which can easily lead to the occurrence of hypoglycemia. Once hypoglycemia occurs, diabetics are prone to brain hypoxia, thereby allowing themselves Feeling dizzy or even unconscious. Because the symptoms of hypoglycemia after drinking are similar to those of drunkenness, it is easily mistaken for a drunken reaction by many patients, which also leads to the occurrence of hypoglycemia without timely rescue, resulting in life-threatening patients.
However, for diabetics, hypoglycemia can be prevented. Try not to drink on an empty stomach when you usually drink. Drinking on an empty stomach will cause alcohol. Absorbed faster, making it easier for hypoglycemia to occur. Therefore, it is best for diabetics to consume some foods with high carbohydrates before drinking, or directly add some sugar, which can reduce the chance of hypoglycemia after drinking.

Hypoglycemia increases the secretion of insulin’s antagonistic hormones (such as epinephrine, glucagon, growth hormone, etc.), causing reactive hyperglycemia, that is, the Sumojie phenomenon, not conducive to blood sugar control.
Low blood sugar affects the energy supply of brain tissue cells, and repeated hypoglycemia can damage brain cells , cause memory loss, unresponsiveness, and even dementia.
Hypoglycemia makes people with diabetes (especially elderly people with diabetes)the function of blood supply to the heart weakens, which is easy to induce myocardial infarction.
