It’s the ninth cold day again, and this year’s cold snap is so fierce that it’s hard for people to adapt at once. In such a cold season, I often hear many diabetic patients complaining that their blood sugar seems to have increased again, and I am at a loss to find the reason. Here’s a summary of the causes of elevated blood sugar in the cold season for diabetic patients. 1, the environment causes the human body to naturally resist the external cold attack, will secrete a lot of response “stress hormones”, such as adrenal hormones, thyroid hormones, etc., and these hormones will lead to an increase in blood sugar. 2, the cold season, the human body is relatively thirsty feeling less obvious, and because the toilet is not so convenient, so it will lead to a reduction in the amount of water drunk every day intentionally or unintentionally, such a situation will lead to blood concentration, so the blood glucose concentration will also rise. 3, in order to resist the cold in winter, people tend to involuntarily increase the intake of energy substances in the diet, and the control of food may be relaxed, and because it is not particularly convenient to exercise in winter, it will also lead to an increase in the sugar converted from fat, protein and other energy substances in the body, thus increasing blood sugar. 4. In winter, due to the cold, the capillaries under the skin of human body will contract to reduce the heat loss in the body, and insulin is precisely injected under the skin and absorbed by capillaries into the whole body to play a role in lowering sugar, so the absorption of insulin will also be reduced at this time, thus raising blood sugar. 5, fast blood glucose meter due to the use of internal circuit components have certain temperature requirements, blood glucose test paper in the detection of blood glucose enzymes also have such temperature restrictions, so when encountering the cold will often lead to the detection value deviated from the real situation in the body, resulting in “blood glucose elevation”. So how to ensure blood sugar stability in the cold season? In response to the above causes of elevated blood glucose, there are five countermeasures. 1, to ensure the appropriate temperature of the living environment and timely increase clothing, to avoid excessive cold stimulation of the human body resulting in excessive secretion of stress hormones; in addition, adhere to participate in such aerobic and coordinated exercises as jogging, Tai Chi, etc. can help improve the body’s ability to resist the cold and balance the sympathetic nerve activity in the body. 2, to ensure that the daily intake of water, to achieve a daily intake of 6 to 8 glasses of water, to avoid the “thirst to drink” such a wrong concept, pay attention to observe the color of urine, to light is good, urine color significantly deepened, then the body has a negative balance of water, the need for timely replenishment of water. 3. No matter what season, you should follow the diet concept of overall energy control, protect the intake of fresh vegetables and fruits, avoid high-fat and high-protein diet, pay attention to the daily intake of a certain amount of coarse grains and legumes, protect the amount of daily exercise, pay attention to sports protection, and avoid accidental injuries. 4. Patients who inject insulin should pay more attention to keep warm, protect the full perfusion of subcutaneous capillaries, which is conducive to the absorption of insulin, and if necessary, increase or decrease the insulin dose according to the blood glucose monitoring results in time to facilitate blood glucose stability. 5, the use of home blood glucose meter pay attention to read the instructions, avoid the wrong detection in low temperature environment, should be regularly tested venous blood glucose and glycated hemoglobin to avoid the error of the blood glucose meter leads to the wrong understanding of blood glucose results. I believe that all sugar lovers will be able to master the cold sugar control skills and spend a cold winter safely.
