It is clinically observed that winter is the season when diabetes is aggravated and more complications occur. Recently, there has been a significant increase in the number of diabetic patients with elevated blood glucose and blood pressure due to cold weather, resulting in concurrent illnesses such as diabetic foot, myocardial infarction, cerebral infarction and cerebral hemorrhage. What should be noted about this situation is that in winter, diabetic patients, especially the middle-aged and elderly, should enhance their awareness of self-care. In addition to effective treatment under the guidance of doctors, they should also do a good job of self-care in daily life to survive the winter safely. For diabetic winter health care should pay attention to the following seven matters: emotional stability: excessive joy, anger and sadness, so that the mood fluctuations, and diabetes has a close and subtle intrinsic link. Therefore, sympathetic nerve excitement can prompt the release of glycogen in the liver into the blood, and the blood sugar level increases, leading to aggravation of the disease or reduce the effectiveness of treatment, so patients should learn to control emotions, avoid negative emotional impact, to maintain emotional stability. Moderate diet: diabetic patients originally eat a lot, especially in winter, when the temperature drops, sweating decreases, the secretion of various digestive juices increases, and the appetite is more vigorous, which is also one of the factors of elevated blood sugar. Diet therapy is one of the basic treatment measures of diabetes. Under the guidance of doctors, diabetic patients should formulate a diet plan according to their weight and complications, and try to achieve a reasonable distribution of meal types and quantities in order to facilitate the control of diabetes. Even in the face of delicious food, you must not indulge in packaged meals, but must be controlled in moderation. Prevention of infection: Respiratory, skin and urinary tract infections are common complications of diabetes, and even become life-threatening factors. Therefore, we should pay attention to the cleanliness of the skin, frequent bathing, skin breaks, boils, folliculitis, etc. should be treated in a timely manner; pay attention to oral hygiene, adhere to the morning and evening, brush and rinse the mouth after meals, suffering from dental disease timely treatment; actively treat chronic pharyngitis, sinusitis, bronchitis, in order to eliminate the hidden danger of pneumonia. Pay attention to foot protection: diabetic patients, more vascular insufficiency and neuropathy, resulting in local sensory dullness of the foot, skin damage or ringworm infection of the foot, etc., can develop into a chronic ulcer that does not heal, or even develop into a serious infection or gangrene that is difficult to control. Sometimes forced amputation or infection spread to the whole body causing life-threatening sepsis. Therefore, diabetic patients should wear loose cotton shoes and socks, often change socks, keep the feet clean and dry. Soak feet with warm water at about 40 degrees every night to help prevent cold and improve local blood circulation; at the same time, prevent bruises, actively treat tinea pedis, avoid tearing the skin of the feet and rubbing toes to stop itching with hands to prevent skin breakage and incur chemical cavity bacterial infection. Pay attention to warmth: cold stimulation can increase catecholamines in the body, prompting an increase in blood pressure and coronary artery spasm, which can easily induce cerebral hemorrhage, myocardial infarction and other serious diseases, so attention should be paid to cold and warmth, and increase clothing in a timely manner. Appropriate exercise: exercise is an important part of the comprehensive treatment measures for diabetes, and is also a measure to enhance the ability to withstand cold and resist disease. Pay attention to blood glucose monitoring In winter, people’s appetite increases greatly, and they eat a lot of fatty and thick food every day to drive away the cold, plus the cold climate, outdoor activities are obviously reduced, resulting in an increase in blood glucose. Therefore, diabetic patients should be diligent in blood glucose testing in winter. Generally speaking, those with milder conditions can have their blood glucose tested once every half month; those with more serious conditions can have their blood glucose tested once every 3 to 5 days or every day, and they should contact their doctors frequently.
