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.

How is hypoglycemia treated?

For mild hypoglycemia, if the patient is conscious, they can self-treat by orally consuming sugary solutions or foods containing carbohydrates, such as beverages, fruit juices, glucose water, candies, etc. In cases of more severe hypoglycemia accompanied by changes in consciousness, oral sugar intake is not advisable. Instead, intravenous glucose injections should be administered to raise blood sugar levels, typically using about 40-100 ml of 50% concentrated glucose. Blood sugar levels should be monitored repeatedly. If the patient does not regain consciousness, repeated glucose injections may be necessary. For severe cases with other organic pathologies, treatment with corticosteroids may be required, and emergency hospital treatment is necessary.

Where to massage for low blood sugar?

Hypoglycemia cannot be treated by massage. The treatment for hypoglycemia involves sugar supplementation. Mild cases can be managed by orally consuming sugar water or sweets, whereas severe cases require intravenous administration of hypertonic glucose. Additionally, it is necessary to screen for the underlying causes and treat them accordingly. Hypoglycemia is defined as blood plasma glucose levels less than 2.8mmol/L. For diabetic patients, a blood glucose level below 3.9mmol/L qualifies as hypoglycemia. The causes of hypoglycemia are numerous, including islet cell tumors, a state of starvation, enhanced insulin sensitivity due to exercise, or inappropriate use of hypoglycemic drugs in diabetic patients. The effects of hypoglycemia on the human body can be severe and require immediate treatment with sugar supplementation. Massage does not serve as a treatment for 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.

What to eat for low blood sugar?

For already occurring hypoglycemia, our treatment goal is to quickly alleviate the symptoms of hypoglycemia. The primary method is to provide sugar, either through sugar water, sugary drinks, or sugar-containing fruits, bread, etc. After providing sugar, the symptoms of hypoglycemia can be quickly relieved. At the same time, to prevent hypoglycemia, we need to do the following: first, eat meals regularly every day, avoiding eating too late or not enough. Second, it is not advisable to exercise on an empty stomach; it is appropriate to eat something before exercising. Third, avoid excessive alcohol consumption, as it can inhibit the conversion of liver glycogen into glucose in the body, making it easy to develop hypoglycemia, so avoid excessive drinking. Fourth, once common symptoms such as palpitations, dizziness, sweating, and other symptoms occur, we should quickly provide sugar.

Can people with hypoglycemia eat meat?

Hypoglycemia refers to a condition where the concentration of glucose in the plasma is too low, below 2.8mmol/L, which is termed hypoglycemia. During hypoglycemia, it is first necessary to quickly replenish glucose to increase the concentration of glucose in the blood and alleviate the symptoms of hypoglycemia. During hypoglycemia, it is best to first eat sugary foods, such as sugar water, chocolate, cookies, fruit juice, etc., which can quickly increase low blood sugar. Eating meat can also improve symptoms of hypoglycemia, but since meat takes longer to be digested and converted into blood glucose by the stomach, it does not quickly relieve symptoms of hypoglycemia. It is best to eat sugar during hypoglycemia, although meat can also be consumed.
