[Health Channel/Comprehensive Report]In addition to the usual care, diabetic patients should also pay special attention to the impact of rising temperature! Xie Anmin, former director of the Cardiac and Cardiac Ward of Veterans Hospital in Chicago, said that diabetic patients are less able to cope with high temperature environments, and are prone to heatstroke, heat exhaustion, and even increase the possibility of hospitalization by 30%. It is recommended to avoid staying in high temperature environments for too long , and increase the frequency of blood sugar measurement to control blood sugar.
Diabetics have poor heat tolerance
Regarding the poor tolerance of people with diabetes to high temperatures, Xie Anmin wrote on his Facebook page “Dr. Xie speaks“The mechanism for maintaining stable body temperature depends on a healthy autonomic nervous system, and most people with diabetes have autonomic dysfunction. Therefore, diabetic patients, especially those with poor blood sugar control, are more difficult to survive in high temperature environments. Maintain normal body temperature.
In addition to autonomic dysfunction, Xie Anmin mentioned that high blood sugar will produce osmotic diuresis, and diabetic patients often need to take diuretic drugs (such as diuretics), so they are more likely to dehydrate.
Xie Anmin said that people with poor blood sugar control have impaired self-regulation of body temperature and are prone to dehydration, so they are more prone to heatstroke; the picture shows the situation. (picture taken from freepik)
Pay attention to 3 major diseases and their impact
As for the health of diabetic patients, Xie Anmin mentioned that there are three common diseases or effects, such as heat stroke, heat exhaustion, or increased carbohydrate and fat metabolism problems:
●Heat stroke, heat exhaustion:Diabetic patients, especially those with poor blood sugar control, are prone to heat stroke and heat exhaustion due to impaired autonomic thermoregulation function, dehydration, and electrolyte imbalance. It is often more serious when it is obtained. People with diabetes were 30 percent more likely to be hospitalized for heat stroke or heat exhaustion than people without diabetes, according to research. For example, during the 1996 New York heat wave, deaths among people with diabetes increased by 117 percent.
●Increased carbohydrate and fat metabolism problems:Electrolyte imbalances, such as hypokalemia, will reduce the secretion of insulin from the pancreas, and will also reduce the effectiveness of insulin, thus making blood sugar control worse and causing problems in carbohydrate and fat metabolism.
●Diabetic ketoacidosis or hyperosmolar hyperglycemic coma:Due to exposure to high temperature environment, even a slight increase in body temperature will lead to an increase in counter-regulatory hormones (hormones that resist the hypoglycemic effect of insulin), making the already disordered and abnormal carbohydrate and fat metabolism of diabetics even more abnormal, and These changes, combined with dehydration, make people with diabetes more likely to be hospitalized for diabetic ketoacidosis or hyperosmolar hyperglycemic coma.
Xie Anmin mentioned that the test strips used in blood glucose monitors used by patients are prone to inaccuracy at high temperatures; the picture shows the situation. (picture taken from freepik)
Precautions for insulin therapy in high temperature environment
Xie Anmin mentioned that under high ambient temperature conditions, people receiving insulin therapy need to have the following three special considerations, such as inaccurate test strips used in blood glucose monitors, which can easily lead to misjudgment of hypoglycemia symptoms, and cannot treat hypoglycemia in time. Blood sugar attack.
●Insulin storage and stability at high temperature:The new formulations have a shelf life at room temperature, so it is no longer recommended to refrigerate insulin. However, at an ambient temperature greater than 30°C, the insulin potency of the vial decreases by about 5% within 4 weeks, and exposure to heat may lead to structural dissociation of insulin and formation of fibrils, thereby increasing the risk of insulin becoming an immune antigen . If you inject insulin that already has filaments formed, the amount of insulin available to your body will decrease.
●Insulin absorption speed becomes faster:Under high temperature, the blood vessels in the skin dilate, increasing the blood flow, so the absorption rate of subcutaneous insulin will be faster than that at normal temperature. According to studies on patients with type 1 diabetes, compared with 20°C, the rate of insulin absorption can be increased by 60% at an ambient temperature of 35°C.
●The blood glucose meter test strip used by the patient is inaccurate:When the temperature is high, the test strips used by the blood glucose meter are inaccurate, especially when the test result is in the low blood sugar range, and the sensor of the continuous blood glucose monitoring instrument may also have this problem. Therefore, some symptoms of hypoglycemia (such as sweating, tiredness, dizziness, headache) may be mistaken for the result of exposure to heat, leaving hypoglycemic episodes untreated in time.
Xie Anmin reminded that from the perspective of climate change trends, high temperatures will continue to occur. It is recommended that diabetics should understand the special precautions when the weather is hot, avoid staying in extremely hot environments for too long, avoid dehydration, and increase the frequency of blood sugar measurement. Keep your blood sugar under control.
