Fasting blood glucose is greater than or equal to 7.8 mmol / L, or 2 hours postprandial blood glucose 11.1 mmol / L, known as hyperglycemia. In daily life, diabetic patients are prone to cause hyperglycemia, and non diabetic hyperglycemia is also common. Long term blood sugar increases can lead to the occurrence of diabetic complications and the health of patients with diabetes, so it is necessary to avoid the increase of blood sugar. Let's look at the factors that lead to a rise in blood sugar.
1., stress hyperglycemia, strong stress factors, such as severe burns, major surgery, cerebrovascular accident, acute myocardial infarction, septic shock and other stress state, increase the secretion of glucocorticoid, antagonize insulin and increase blood glucose. After general stress, the 7~10 sky abdominal blood glucose returned to normal.
2. drugs can cause hyperglycemia, hyperglycemia and many drugs, including diuretics, anti-cancer drugs, antihypertensive drugs, female contraceptives, tricyclic antidepressants, glucocorticoids, phenytoin, indomethacin, aminophylline, cimetidine, thyroxine etc..
3., gestational hyperglycemia, the secretion of growth hormone from the placenta can increase blood glucose, and the blood glucose after delivery is gradually restored to normal. However, about 30% of the maternal development is true diabetes.
4., hypophyseal hyperglycemia is caused by excessive secretion of growth hormone, which results in abnormal glucose metabolism and hyperglycemia.
5. hyperglycemia due to hyperthyroidism, thyroid hormone excess glucose increased gastrointestinal absorption, enhanced excitability of sympathetic nerve leads to reduced insulin secretion, glycogen production increased, tissue decreased glucose uptake, increased glycogenolysis and other reasons caused hyperglycemia.
6. hepatic hyperglycemia, acute and chronic hepatitis, liver cirrhosis, widely damage, liver glycogen synthesis dysfunction, decreased glycogen reserve capacity, prone to high blood sugar after meals.
7., pancreatic hyperglycemia, due to pancreatic resection, pancreatic cancer and acute inflammatory reaction of pancreas, directly causes islet damage, antibody stress reaction and glucagon excessive release can cause transient hyperglycemia.
8. endocrine tumors cause hyperglycemia, Cushing's syndrome, glucagon tumor, islet A cell tumor, islet D cell tumor, pheochromocytoma and so on, all can cause blood sugar to rise, which is mainly related to various hormones that cause abnormal glucose metabolism in vivo.
9. hemachromatosis bronze face, liver cirrhosis, cardiovascular disease, sexual dysfunction in patients with hyperglycemia, should be suspected hemochromatosis. The iron is the secondary hyperglycemia caused by the destruction of the pancreas and the destruction of the beta cells of the islets.
