After a hypoglycemic episode, we need to handle it quickly. Usually, based on symptoms of hypoglycemia, such as dizziness, palpitations, cold sweats, pale complexion, and trembling hands, we can preliminarily judge the likelihood of a hypoglycemic attack. Then, use a rapid glucose meter to measure fingertip blood sugar levels. For non-diabetic patients, a blood sugar level below 2.8 mmol/L and for diabetic patients, a level below 3.9 mmol/L can be indicative. Next, we quickly provide sugar, offering oral sugar water, sugary drinks, or sugar-containing fruits, cookies, bread, etc. After these treatments, the symptoms of hypoglycemia can be quickly alleviated.

Standard for Low Blood Sugar

Our diagnostic criteria for hypoglycemia are often based on the "Whipple's triad," which is determined first by the presence of symptoms of hypoglycemia, such as palpitations, dizziness, pale complexion, cold sweats, confusion, mental abnormalities, and so on. Second, after the symptoms appear, we measure blood glucose; in non-diabetic patients, blood glucose below 2.8 mmol/L, and in diabetic patients, blood glucose below 3.9 mmol/L, then it can be judged as possibly hypoglycemia. Third, after measuring blood glucose, we quickly provide sugars, administer oral sugar water, biscuits, etc., and his symptoms of hypoglycemia quickly alleviate. Based on these three points, we can diagnose hypoglycemia.

How to regulate hypoglycemia

If hypoglycemia occurs repeatedly, it is necessary to go to the hospital for an examination to rule out some diseases that may cause hypoglycemia. If no apparent diseases are found after the examination, self-regulation can be considered. The methods for self-regulation include the following: Firstly, pay attention to a reasonable diet, eat regularly, balance meat and vegetables, and develop good eating habits without excessive dieting. Secondly, persist in exercising to strengthen the body, enhance physical fitness, improve immunity, and reduce the occurrence of hypoglycemia. Lastly, develop good living habits, ensure adequate sleep, avoid staying up late, avoid excessive fatigue, and balance work and rest.

Does low blood sugar cause confusion?

When hypoglycemia occurs, it is possible to experience confusion. This is because, under normal conditions, the glucose level in our brain tissue is only about 25% of that in our blood. After hypoglycemia occurs, the glucose concentration in our brain tissue will further decrease, leading to a state of sugar and oxygen deprivation in the brain. Severe cases can exhibit a range of neuropsychiatric symptoms such as behavioral changes and confusion, cognitive dysfunction, or even epileptic seizures. Some patients may also experience coma and permanent brain damage, typically seen in those with severe and prolonged hypoglycemia. Similarly, patients who repeatedly experience hypoglycemia often also suffer from brain atrophy. Therefore, confusion can occur during hypoglycemia.

How to alleviate hypoglycemia

In general, for hypoglycemia, if a diabetic's blood sugar falls below 3.9 or a non-diabetic's blood sugar falls below 2.8, it is considered hypoglycemia. In terms of treatment, if the patient is conscious and experiences symptoms such as dizziness, palpitations, cold sweat, and hunger, it is recommended to measure blood sugar immediately and then eat foods that quickly increase blood sugar levels, such as chocolate or candy. If hypoglycemia in a patient is not corrected in time, it can lead to coma. If the patient is comatose, it is advised to call emergency services immediately and administer a 50% glucose intravenous injection to correct the hypoglycemia.

What are the symptoms of hypoglycemia?

Hypoglycemia, in fact, is diagnosed in healthy individuals when blood glucose levels are less than or equal to 2.8 mmol/L, and in diabetic patients when levels are less than or equal to 3.9 mmol/L. Common symptoms of mild hypoglycemia typically involve sympathetic nervous system activation, such as dizziness, palpitations, cold sweats, trembling hands, and a feeling of hunger. It is recommended that food be consumed promptly when these symptoms occur. If hypoglycemia is not immediately addressed, severe outcomes can occur, including altered mental status, coma, and unresponsiveness. In some cases, hypoglycemia may trigger seizures or abnormal cerebral vascular accidents, such as stroke or cardiac ischemia, leading to a heart attack. Therefore, preventing hypoglycemia is of utmost importance.
