A sudden and fierce pneumonia outbreak of a new coronavirus infection has overshadowed the land and spread across the country. With the Lunar New Year more than a week away, the weather is clearing, the temperature is rising, safety is paramount, and we still need to stay home, clean and disinfect, and protect ourselves from the epidemic. During this period, diabetic patients have greater changes from their usual diet, exercise and emotions, which in turn lead to significant blood glucose variability. Blood glucose variability, also known as blood glucose fluctuation, reflects the non-stationary state in which blood glucose levels fluctuate between their fluctuating high and low values, and usually includes intra-day blood glucose variability and inter-day blood glucose variability. Blood glucose variability increases the risk of diabetic complications by activating oxidative stress pathways, damaging endothelial cell function and exacerbating chronic inflammation, which is even more serious than persistent hyperglycemia. For diabetes management, it is not only necessary to lower glucose, but also to lower glucose in a high-quality and smooth manner to reduce the variability of glucose. In this special period, how to control sugar, how to “steadily” win the battle? In general, there are three major causes of blood glucose variability during the extraordinary period: 1. Lifestyle changes: the intake of more high-calorie food causes postprandial blood glucose to rise, and the inability to eat regularly and quantitatively also causes hyperglycemia or hypoglycemia; the time for exercise, including outdoor exercise, decreases and the intensity decreases, leading to the rise of blood glucose. 2, psychological factors: about 1/4 of type 2 diabetes or type 1 diabetes patients have depressive symptoms or depressive disorder, coupled with the impact of the epidemic, which can aggravate or trigger anxiety and depression. The blood sugar of diabetic patients with depression and anxiety is not easily controlled satisfactorily. 3, drug factors: affected by the epidemic, the inconvenience of taking hypoglycemic drugs, or the original treatment plan can not meet the needs, or poor patient compliance, can not be used in accordance with medical advice, increasing the variability of blood sugar. In response to the main causes of increased blood glucose variability, corresponding countermeasures should be taken to minimize blood glucose fluctuations. In areas where the epidemic is not under control, indoor exercises such as tai chi and aerobics are recommended. The above exercises can be interspersed with resistance exercises (e.g. pull-ups, dumbbell lifting, etc.), and at least 30 minutes of exercise time should be maintained every day. Second, maintain a good state of mind Zhong Nanshan academician said: “half of the health is mental health, half of the disease is mental illness. In extraordinary times, it is more important to maintain a good state of mind, do not be overly nervous and anxious. Always learn formal knowledge of disease prevention from the authoritative media, do not listen to gossip, so as not to increase unnecessary anxiety. Do more things that interest you. Patients need to follow the doctor’s prescriptions for medication. During the Chinese New Year, even if it is inconvenient to prescribe or purchase medication, patients must still follow the doctor’s prescriptions for medication and should not stop taking medication on their own or replace it with other medication they have on hand because of saving medication. If you run out of medication, you should contact a community health service center to obtain medication as soon as possible. In areas where the epidemic is under control, it is also safe to go to the hospital for prescriptions on the basis of good personal protection.
