What causes low blood sugar? How hypoglycemia is caused

Hypoglycemia is a syndrome characterized by sympathetic hyperexcitation and brain dysfunction caused by a sudden drop in blood sugar below millimoles (50 milligrams deciliters) caused by a variety of causes. Blood sugar drops rapidly, and patients often have hunger, nausea, vomiting, weakness, weakness, nervousness, anxiety, palpitations, cold sweats, paleness, high blood pressure, tremors, etc.; When blood sugar drops further, the patient may experience confusion, drowsiness, convulsions, and coma; Long-term and severe hypoglycemia can cause brain damage, such as coma for more than 6 hours, which can cause irreversible brain damage and then cause death.

Hypoglycemia is most common** due to overdose or inappropriate use of insulin or sulfonylureas in patients with diabetes; Elderly diabetic patients, even if they are in stable condition and do not have **, are prone to hypoglycemic reactions before lunch or dinner.

For the prevention of hypoglycemia, first of all, eat within 30 minutes after insulin injection, when the amount of activity increases, a small amount of meals should be added in time, do not forget to eat on time when going out, and patients taking sulfonylurea hypoglycemic drugs should also eat in time; Secondly, patients who inject mixed insulin should pay special attention to eating dinner on time and eating more staple foods or eggs, dried tofu, etc. before going to bed. Third, carry some sugar cubes, cookies, etc., with you in case of hypoglycemic reactions.

When hypoglycemia is acutely attacked:

1. Patients with mild reactions and conscious should take 25-50 grams of white sugar or brown sugar with warm boiled water or drink other sugary drinks; Slightly heavier people eat 25 grams of steamed bread, bread or biscuits, or 1-2 fruits, and the reaction can disappear after 10 minutes.

2. If the hypoglycemic reaction is severe and the consciousness is not very clear, white sugar or brown sugar can be placed in the patient's mouth to dissolve and swallow; Or mix into syrup and feed slowly. If you are still not awake after 10 minutes of taking sugar, you should immediately send to a nearby hospital for rescue.

3. For patients in hypoglycemic coma, 40 ml of 50 glucose should be injected intravenously immediately, and oxygen should be given, which will soon be effective, or 1 mg of glucagon should be injected intramuscularly, and consciousness should be awake within 15 minutes. After waking up, the patient must be given sugar water, etc., to prevent the next reactive hypoglycemia.

Hypoglycemia basic** can be classified differently according to different criteria:

1. Classified according to pathophysiology.

1) Insufficient sugar intake. This is easy to understand, and for some people who are on a diet, it is especially easy to cause hypoglycemia due to too little carbohydrate intake. For those who take dietary plans such as "fasting" or "low-carb diet" for blood sugar control, there is also a certain risk of inducing hypoglycemia;

2) Insufficient sugar production. Decreased hepatic glycogen synthesis or glycogenogen decomposition disorders caused by certain diseases, resulting in disorders of glucose metabolism in the body, and inability to supply energy to the body in time when there is no external sugar intake;

3) Excessive sugar consumption. For example, under the condition of strenuous exercise, the body consumes too much sugar and is too late to replenish it, which can easily lead to hypoglycemia. Therefore, sugar friends are also reminded: first, do not exercise excessively, and second, prepare some candy, drinks, etc. during exercise in case of emergency;

4) Excessive sugar inversion. It is common in overdose of insulin and overdose of insulin secretagogues, which will cause excessive conversion and consumption of sugar in the body and lower blood sugar.

2. Classified by clinical diagnosis.

1) Organic hypoglycemia. Hypoglycemia due to organic lesions, such as impaired glycogen production and breakdown due to liver disease, excessive insulin secretion due to pancreatic islet cell hyperplasia, glycogen storage disease caused by congenital glucose metabolizing enzyme defects, ......Wait a minute;

2) Functional hypoglycemia. Postprandial hypoglycemia (also known as "reactive hypoglycemia") is when the release of insulin after a meal is slower than the increase in blood glucose levels (i.e., delayed insulin secretion), so when the concentration of insulin in the blood peaks, the blood sugar level has begun to drop, resulting in a hypoglycemic reaction;

3) Exogenous hypoglycemia. It is mostly related to diabetes itself, such as excessive use of hypoglycemic drugs, significant reduction in food intake, etc., which induces hypoglycemia.

1.Eating less, for example, many people go to work without breakfast, and children with high-intensity work have high energy and show sweating; dizziness; rapid heartbeat; Eyes with golden flowers; Shiver; hunger; Impotence; numbness in the hands and feet; slurred speech; Dysphoria; personality changes; disorientation; seizures; Coma.

2.There are also diabetic patients who take insulin injections with inappropriate amounts of hypoglycemic drugs, which can also lead to hypoglycemia.

The response to hypoglycemia is very different from the degree, speed and duration of blood sugar reduction Our normal blood sugar, what I just talked about, if it is lower, there will generally be a hypoglycemic reaction. There are six early hypoglycemic reactions, one is fatigue, the second is palpitation, the third is sweating, the fourth is shaking hands, the fifth is hungry, and the sixth is impaired mental awareness. <>

If the hypoglycemia is severe, it will cause coma and even death, so we should pay strict attention to the hypoglycemia of the elderly, it is easy to mix with cerebrovascular diseases, so for the elderly to control blood sugar, we must strictly observe closely.

Experts conclude that the symptoms of hypoglycemia are related to the degree, speed, duration and individual differences of blood sugar reduction, and the main manifestations in the early stage are fatigue, palpitation, sweating, hand tremors, and hunger. <>

There are many reasons for hypoglycemia, for young people, the most common cause of hypoglycemia in normal people is because of the amount of food eaten relatively small and the amount of exercise at the same time caused by hypoglycemia, for some patients with Tang Urine disease, anti-hypoglycemia may be caused by drug overdose, sometimes patients overdose or excessive exercise, reducing diet will lead to the reduction of blood sugar that diabetic patients have controlled There are also some special groups of people who have reversed ** hypoglycemia, and the diet is regular, and there is no use of drugs**, This group of people needs to be alert to the possibility of insulinoma Because of the presence of insulinoma, which leads to the production of hypoglycemia, it requires aggressive surgery**. <>

The reason for low blood sugar is to eat more green vegetables, fruits, especially dark vegetables, increase seafood intake appropriately, and eat more calcium.

This is due to insufficient sugar intake, excessive consumption, and excessive transformation.

There are many factors that can cause the symptoms of hypoglycemia, such as skipping breakfast for a long time, not getting enough sugar, or because of too much conversion, or because of excessive sugar consumption.

The main reason is that our body's sugar metabolism makes it impossible for our body to keep up with its needs, and the body's energy is too small.
