Hypoglycemia
The dangers of hypoglycemia
Hypoglycemia poses the greatest harm to the body by damaging brain tissue. If the drop in blood sugar is severe and prolonged, it can cause brain dysfunction due to glucose deprivation in brain tissues. This mainly manifests as changes in the patient's consciousness and personality, and can present as weakness, fatigue, and cognitive impairment. In severe cases, it can lead to seizures or coma. Additionally, degeneration and necrosis can occur in the neurons of the central nervous system within the brain cells, along with cerebral edema, diffuse cerebral hemorrhage, or periodic demyelination. If severe and persistent hypoglycemia is not effectively corrected, it can lead to permanent brain function impairment or death.
What does hypoglycemia lack?
Hypoglycemia refers to a decrease in the concentration of glucose in the blood, known as hypoglycemia. Generally, for the normal healthy population, a blood glucose concentration below 2.8 mmol/L is considered hypoglycemia. For diabetic patients, a blood glucose concentration below 3.9 mmol/L is considered hypoglycemia. Of course, this can also be due to some endocrine diseases, such as pituitary insufficiency, adrenal cortex insufficiency, and hypothyroidism leading to hypoglycemia. In addition to the low concentration of glucose in the blood, there may also be a decrease in some hormone levels related to pituitary, adrenal, and thyroid functions, such as decreased cortisol and thyroid hormone levels, which are also deficiencies in the body.
Can people with hypoglycemia exercise?
Generally speaking, when hypoglycemia occurs, one should first correct the low blood sugar levels and identify the cause of the hypoglycemia before engaging in exercise. This is because hypoglycemia can manifest in various ways depending on the cause, the degree and speed of the blood sugar drop, and the individual's response. For instance, some patients may exhibit symptoms of excessive sympathetic nervous system activation, such as sweating, trembling, palpitations, hunger, anxiety, tension, and a slight increase in blood pressure. If hypoglycemia is not corrected, it can lead to a further decline in blood sugar levels, resulting in symptoms of neuroglycopenia. These may include lack of mental focus, dizziness, sluggishness, blurred vision, unsteady gait, and even hallucinations, restlessness, abnormal behavior, and other psychotic manifestations. Some may also exhibit confusion, infantile movements, choreiform movements, and even some spasms, coma, and a drop in blood pressure. Therefore, hypoglycemia is a serious condition and exercise should only be undertaken after it has been corrected.
Can people with hypoglycemia run?
The treatment of hypoglycemia primarily involves identifying its causes, whether due to an excessive use of medication by diabetic patients, not eating meals on time, or other reasons such as an insulinoma or other causes. In these cases, treatment should focus on the underlying causes. Or, if the hypoglycemia is simply due to not eating regularly, consider if symptoms such as frequent palpitations and easy sweating are present. If you must go running, it is advised to first correct the hypoglycemia by consuming some food to raise the blood sugar. Additionally, during the run, always carry some food with you. If symptoms of low blood sugar occur, you should eat immediately, as running can consume the glucose in the blood and lower blood sugar levels. If you do not eat on time to increase your blood sugar, it might induce severe hypoglycemia. Therefore, it is recommended to correct the blood sugar level before running, and make sure to carry food with you while running.
Hypoglycemia is caused by what?
Hypoglycemia is most commonly seen in patients with type 2 diabetes. During the treatment of diabetes, hypoglycemia can occur due to excessive use of medication or insulin, failure to eat on time after exercise, or decreased appetite without appropriately reducing the medication. Another common cause is insulinoma, a type of tumor that secretes excessive insulin, resulting in lowered blood glucose levels. A third cause relates to the early stage of type 2 diabetes, where insulin resistance and delayed insulin peak times often lead to pre-meal hypoglycemia, especially before lunch and dinner. Lastly, hypoglycemia is also commonly observed in some young women with specific coloring, potentially due to gastrointestinal motility issues or other reasons leading to pre-meal hypoglycemia. It is also common in patients with hepatitis or cirrhosis, where the liver's ability to output glucose is diminished, increasing the risk of hypoglycemia when fasting.
Manifestations of Hypoglycemia
When the blood glucose level of a normal person falls below 2.8mmol/L, or for diabetics below 3.9mmol/L, it is referred to as hypoglycemia. Hypoglycemia refers to a clinical syndrome caused by an abnormally low glucose concentration in the blood due to various reasons. Clinically, it primarily manifests through symptoms stimulated by the sympathetic nervous system and affects on the central nervous system. Typical signs of hypoglycemia include excessive sympathetic nervous excitement, such as sweating, hunger, palpitations, trembling, and paleness. Additionally, there are manifestations of brain dysfunction, initially presenting as lack of concentration, slow thinking and speech, dizziness, drowsiness, restlessness, irritability, and bizarre behavior. In severe cases, seizures, coma, and even death may occur.
Can people with hypoglycemia eat beef?
Whether or not patients with hypoglycemia can eat beef really depends on the specific situation. Hypoglycemia varies in severity from mild, moderate, to severe. If you're just experiencing slight low blood sugar with some hunger and mild sweating, without any mental or physical impairments, then eating some beef shouldn't be a problem and it can indeed help raise your blood sugar. However, if you are experiencing moderate or severe hypoglycemia, characterized by heavy sweating, dizziness, and especially changes in consciousness, then it is not recommended to eat beef because its digestion and absorption are slow. In such cases, it is advised to quickly drink sugary water, and if necessary, administer sugar water intravenously to swiftly increase the blood sugar levels and alleviate symptoms of hypoglycemia. Since beef is a protein, it digests slowly and therefore causes a slower rise in blood sugar.
Is hypoglycemia dangerous?
For diabetic patients, hypoglycemia is defined as glucose levels less than 4 mmol/L, and for non-diabetic individuals, or healthy people, low blood sugar is characterized by levels less than 2.8 mmol/L. Hypoglycemia initially causes metabolic abnormalities in the brain since brain cells in the middle of the brain can't break down fats or proteins; they can only use the simplest sugars, which is the glucose in our blood, as their energy source. When the concentration of sugar in the blood decreases, the brain cells fail to absorb enough energy, which can lead to abnormalities in brain function, resulting in symptoms like fatigue and drowsiness. If glucose is not consumed at this point, the further deficiency in energy for brain cells may lead to coma, making hypoglycemia a very dangerous condition.
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.
Does hypoglycemia spread?
Hypoglycemia is not a contagious disease, so it is not transmittable. Hypoglycemia is primarily caused by excessive secretion of insulin in the body, or by consuming too little sugary food, leading to abnormally low blood sugar levels and certain clinical symptoms such as palpitations, trembling hands, fatigue, and cold sweats. Therefore, it is caused by pathological reasons within the body itself, and not by infectious bacteria or viruses from external sources, so it is not contagious. However, when hypoglycemia occurs, it is necessary to promptly consume sugary foods to alleviate the symptoms and prevent more serious damage to the body.
