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.

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 is hypoglycemia treated?

The treatment for hypoglycemia is relatively simple; in most cases, it involves immediate consumption of sugar water to replenish energy, which can significantly alleviate the symptoms of hypoglycemia. If it is an occasional, single occurrence of hypoglycemia, normal status can be restored after replenishing energy. However, if hypoglycemia occurs repeatedly, it is necessary to seek timely medical treatment at a hospital to rule out some common diseases that cause hypoglycemia.

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.

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.

Can people with hypoglycemia exercise?

Hypoglycemia refers to a plasma glucose concentration lower than 2.8 mmol/L, at which point patients may exhibit signs of sympathetic nervous excitement, such as trembling hands, palpitations, pale complexion, profuse sweating, feelings of hunger, and fatigue. There can also be brain function disturbances, leading to symptoms like dizziness, blurred vision, hallucinations, and bizarre behavior. At this time, it is not advisable to exercise. Instead, immediate rest is recommended, along with the consumption of sugary foods to raise blood sugar levels. Exercise is strictly prohibited as it can lead to unnecessary physical injuries, such as falls.
