1 Insulin deficiency, absolute or relative deficiency, decreased sensitivity of target cells to insulin, impaired glucose utilization, disordered glucose metabolism and increased blood sugar. It is found in pancreatectomy of diabetes, pancreatic cancer, acute and chronic pancreatitis, etc.
2 Ingesting a lot of sugary food or intravenous glucose, the intestinal absorption is too fast, and blood sugar cannot be converted into glycogen due to severe liver disease and liver dysfunction, which leads to an increase in blood sugar.
3 liters of blood glucose hormone rises, which makes blood sugar rise. Such as glucagon, growth hormone acromegaly, glucocorticoid, adrenaline, thyroxine, etc.
4. Stress hyperglycemia, such as craniocerebral trauma, cerebrovascular accident, acute myocardial infarction, etc. , leading to excessive secretion of adrenaline and glucagon and elevated blood sugar.
5 gestational diabetes mellitus, changes in islet function during pregnancy, decreased glucose tolerance, leading to increased blood sugar.
6. Drug-induced hyperglycemia, such as corticosteroids, thiazide diuretics and oral contraceptives. It has the effects of inhibiting insulin, raising blood sugar and turning fruit into fruit.
Question 2: Why is people's blood sugar high? Introduction: Causes of hyperglycemia 1: Unexpected hyperglycemia. If you eat a lot of sweets before the blood sugar test, of course you will have high blood sugar. So it's hyperglycemia, so don't worry too much. After a period of time, check it again to see the blood sugar results. The second cause of hyperglycemia: hyperglycemia caused by unreasonable diet. Now most young people like fast food like KFC, but they don't like vegetables and fruits. Long-term eating habits may lead to hyperglycemia. Although there are no symptoms at ordinary times, long-term hyperglycemia will inevitably cause harm to the body. Cause 3 of hyperglycemia: hyperglycemia caused by other diseases. Coronary heart disease is closely related to hyperglycemia. Therefore, once diagnosed as hyperglycemia, we should try our best to understand what causes hyperglycemia, so as to prescribe the right medicine and do a good job in the prevention and treatment of hyperglycemia. Reason 4 of hyperglycemia: After excluding the above reasons of hyperglycemia, hyperglycemia is most likely the early symptom of diabetes. At present, diabetic patients are getting younger and younger, and even childhood diabetes appears. So what diabetics must know is that hyperglycemia should be treated as soon as possible. Water can not only dilute blood sugar, but also dilute blood viscosity; Water can discharge nitrogen-containing waste and prevent cardiovascular diseases. If there is no kidney or heart disease, and there are no other drinking restrictions, people with hyperglycemia should develop the good habit of drinking water regularly, and drink about 2000 ml (10 cup) every day. Some people with high blood sugar think that "drinking too much" will cause "polyuria", and they are afraid of drinking water. Actually, this is a misunderstanding. High blood sugar, drink plenty of water because these people have high blood sugar concentration, and only when the urine volume increases can excess sugar be discharged; Moreover, if you have too much urine, your body loses too much water, you feel thirsty and need to drink more water. This is a self-protection measure for your body. In other words, it is polyuria that causes polyuria, not polyuria that causes polyuria. What dietary fiber can slow down the digestion and absorption of food in gastrointestinal tract, control the increase of blood sugar after meals and improve glucose tolerance? People with high blood sugar should learn to match their diets scientifically in their daily lives, such as adding coarse grains such as oats and buckwheat, and fresh fruits and vegetables and kelp with low sugar content. However, excessive intake of dietary fiber will lead to indigestion and affect the absorption and utilization of protein, calcium, iron, zinc and other nutrients. If you suddenly change from a low-fiber diet to a high-fiber diet in a short time, it can cause a series of digestive tract intolerance reactions such as flatulence, diarrhea and abdominal pain. Therefore, attention should be paid to increasing foods containing dietary fiber step by step. Cereals are the main food for women with hyperglycemia and diabetes. A balanced diet must consist of a variety of foods to meet various nutrients in the human body. It is a fine tradition of our country to give priority to cereals, so it is necessary to avoid the dietary disadvantages of animal foods in developed countries. In addition, we should pay attention to the matching of thickness and often eat some coarse grains. Rice and wheat foods should not be too delicate to prevent the loss of vitamins, minerals and dietary fiber contained on the grain surface. 5, in addition to fruit, other sweets should be listened to for the time being. Most women like sweets. Small snacks such as chocolate, wafers and biscuits are also very popular with expectant mothers during pregnancy, and they are almost necessary at home. It is worthwhile to control your desires for your own health and your baby's health.
Question 3: Why does blood sugar rise (1) Climate factor: Cold stimulation can promote adrenaline secretion. The output of liver glycogen increases, and the intake of glucose by muscle decreases, which aggravates the situation of blood sugar increase; It is hot and sweaty in summer, so pay attention to hydrating, otherwise the blood will be concentrated and the blood sugar will rise. (2) Cold: Blood sugar can be raised after a cold. (3) Patients with fever due to trauma, surgery, infection, severe mental trauma, vomiting, insomnia, anger, anxiety, irritability, fatigue, acute myocardial infarction, etc.: can make blood sugar rise rapidly and even induce diabetic ketoacidosis. (4) Insufficient drug dosage: some patients reduce their drug dosage by themselves; Some people do not check blood sugar for a long time, so that the original dose is not adjusted in time after the blood sugar rises, which will lead to the increase of blood sugar and even ketoacidosis due to insufficient drug dose. (5) Sudden changes in working environment and living environment: leading to temporary adverse reactions of patients. (6) Excessive intake of high-fat food: the islet function can not secrete insulin well, and blood sugar is increased. (7) Long-term constipation: lead to metabolic disorder, adverse blood circulation, and affect blood sugar. (8) Insufficient drinking water: it leads to metabolic imbalance and affects blood sugar.
Question 4: What happens when people have high blood sugar? The increase of blood sugar and urine sugar can cause osmotic diuresis, thus causing polyuria symptoms; When blood sugar rises and a large amount of water is lost, the osmotic pressure of blood will also increase accordingly. Hypertonic pressure can affect the thirst center of hypothalamus, thus causing symptoms of thirst and polydipsia; Due to the relative or absolute lack of insulin, glucose in the body can not be utilized, and protein and fat consumption increase, thus causing fatigue and weight loss; In order to compensate for the lost sugar and maintain physical activity, we should eat more; This has formed a typical "three more and one less" symptom. The symptoms of polydipsia and polyuria in diabetic patients are directly proportional to the severity of the disease. In addition, it is worth noting that the more patients eat, the higher their blood sugar, the more sugar they lose in their urine, and the more hungry they feel, which eventually leads to a vicious circle. Therefore, in this case, it is better to eat less, but the daily staple food should not be less than150g. However, if diabetes is not relieved and the patient's appetite suddenly drops, we should pay attention to whether there are complications such as infection and ketosis.
Question 5: Why do people have high blood sugar? . . . The blood sugar level of human body depends on the function of islet. If the islet function is normal, the blood sugar will not be high or low. If the islet function is low, blood sugar will be high, or hypoglycemia will occur due to insufficient sugar intake; When the islet function is high, hypoglycemia will occur.
Insulin can be compared to a sugar porter. When blood sugar is high, sugar is transported to the liver, and when blood sugar is low, glycogen in the liver is moved to the blood, thus ensuring the stability of human blood sugar.
So you can understand? I appreciate your thirst for knowledge.
There is sugar: diabetes education at any time
Question 6: Why do young people have high fasting blood sugar? This year they should be able to achieve the small goals set at the beginning of the year.
Question 7: Why do people with high blood sugar emphasize more exercise? First of all, exercise refers to aerobic exercise. Our usual exercise is aerobic exercise, so what does aerobic exercise consume?
It's glycogen When the glycogen stored in our muscles is consumed, the polysaccharide in the blood will naturally be converted into glycogen to supplement the inside of the muscles, and the natural blood sugar concentration will be reduced.
It is also important to control your diet and eat less sugary food.
Question 8: Why do people have high blood sugar? What is the reason? At present, it is believed that the occurrence of hyperglycemia is mainly related to the following mechanisms:
1. Pancreatic β cells can't secrete enough insulin, and α cells secrete too much glucagon.
2. Peripheral tissues including liver, muscle and adipose tissue have insulin resistance.
3. Intestinal absorption, intestinal flora and intestine affect blood glucose control hormones, leading to their abnormality.
4. Excessive absorption of sugar by the kidneys.
5. Abnormal regulation of glucose metabolism by nervous system.
Question 9: Why do people have high blood sugar at night? Depending on whether it is before or after meals, it will increase after meals. The following is the standard range, which can be used as a reference, and then see if you have eaten any high-sugar food.
Normal fasting blood glucose:
①: Generally, fasting blood glucose is 3.9 ~ 6.1mmol/L (70 ~110 mg/dl), and plasma glucose is 3.9 ~ 6.9 mmol/L. ..
②: Fasting blood glucose ≥6.7 mmol/L( 1.20mg/dl) and blood glucose ≥ 7.8 mmol/L. Repeated measurement can diagnose diabetes.
③ When the fasting blood glucose is above 5.6 mmol/L (100 mg/dl) and the plasma glucose is above 6.4 mmol/L (115 mg/dl), a glucose tolerance test should be done.
④ When fasting blood glucose exceeds11.1mmol/L (200 mg/dl), it means that insulin secretion is little or lacking. Therefore, when fasting blood glucose is significantly increased, diabetes can be diagnosed without other tests.
Normal postprandial blood glucose:
65438+ 0 hour after meal: blood sugar 6.7-9.4 mmol/L. The maximum is11.1mmol/L.
2 hours after meal: blood sugar ≤ 7.8 mmol/L.
3 hours after meals: it returned to normal after 3 hours, and urine sugar was negative every time.
Yuan Yitang Metabolic Conditioning Expert: Diabetes is caused by metabolic problems. The main reasons for metabolism are: eating too much, eating wrong and exercising less. Therefore, the prevention and treatment of diabetes must start with the regulation of metabolism.
Question 10: Why do young people also have high blood sugar? What effect does it have on the body? Hyperglycemia is regardless of age, and some are born. Hyperglycemia mainly affects other organs of the body. It can be adjusted by Ali tree health care products controlled by the rainforest to restore normal blood sugar as soon as possible!
