为什么在应激状态下血糖会升高 李华 徐州矿务集团总医院
机体在受到一些异乎寻常的刺激，比如说手术、外伤、电击、中毒、感染、剧痛、刺激的情绪激动和严重的精神刺激引起的紧急状态，称为应激状态。此时，交感神经兴奋，肾上腺素、胰高血糖素、肾上腺皮质激素及生长激素等分泌增加，而胰岛素分泌减少。肾上腺素、肾上腺皮质激素等分泌增加使糖原分解和糖异生，并抑制周围组织对糖的利用，使血糖升高。与之相拮抗的胰岛素分泌减少，又使血糖进一步升高。处于应激状态下，血糖升高有利于保证体内重要器官比如说大脑、红细胞等的葡萄糖供应。正常人处于应激状态时，血糖不会过高，即使出现高血糖也是短暂的，高血糖刺激胰岛β细胞，胰岛素分泌会随之增高，高血糖将很快得到纠正而恢复正常。而糖尿病患者，由于体内胰岛素绝对或相对不足，则失去这种激素的调节能力，处于应激状态时，高血糖不能得到及时纠正，将使糖尿病恶化。所以糖尿病的病人要控制好情绪，减少更多应激因素，避免使自己暴露在各种不良的情况之下血糖恶化血糖升高，我们在生活中一定要保持好平稳的的心境，然后这样减少更多不良的情绪才能控制好血糖。
Why does blood sugar rise under stress
The body is under some extraordinary stimulation, For example, emergency caused by operation, trauma, electric shock, poisoning, infection, sharp pain, exciting emotion and severe mental stimulation, It is called stress state. At this point, Sympathetic excitement, The secretion of adrenaline, glucagon, adrenocortical hormone and growth hormone increased, Insulin secretion decreased. The secretion of adrenaline, adrenocortical hormone and so on increases glycogenolysis and gluconeogenesis, And inhibit the utilization of sugar by surrounding tissues, Increase blood sugar. In contrast, insulin secretion decreased, And make blood sugar rise further. In a state of stress, The increase of blood sugar is helpful to ensure the supply of glucose to important organs such as brain and red blood cells. When normal people are in a state of stress, Blood sugar is not too high, Even hyperglycemia is transient, Hyperglycemia stimulates islet β cells, Insulin secretion will increase, Hyperglycemia will soon be corrected and returned to normal. And diabetics, Because of the absolute or relative lack of insulin in the body, It loses the regulatory power of this hormone, In a state of stress, Hyperglycemia cannot be corrected in time, Will make diabetes worse. So diabetic patients should control their mood, Reduce more stressors, Avoid exposing yourself to all kinds of bad conditions, blood sugar worsens, blood sugar rises, We must keep a stable mood in our life, Then you can control your blood sugar by reducing more bad emotions.
