The bells of the Year of the Rat sounded the call for the nation to stop the battle against the new coronavirus. From the more limited data available, the situation of patients with severe new coronary pneumonia and those who unfortunately died as a result are generally combined with the presence of certain underlying diseases as well as some special groups for whom the scientific response to new coronary pneumonia becomes particularly important. Emotions can affect blood sugar. Adverse emotions can have an impact on insulin secretion, which is more pronounced in middle-aged and elderly people. Bad emotions such as tension, anxiety, loneliness and despair can make diabetics’ disease recur or worsen. Academician Zhong Nanshan said: “Half of health is psychological health, half of disease is psychological disease”. The worry of sugar lovers about the epidemic is a very normal psychology, which can help us to prevent infection cautiously, but excessive worry is not only unhelpful, but also may cause psychological crisis and blood sugar fluctuation. Therefore, sugar lovers should first believe in the power of the country, government and people, and have confidence in the current rescue, treatment and prevention and control efforts. Secondly, do a good job of personal protection, develop personal hygiene and prevention habits, and remind people around you to do a good job of health protection. Also, stay rational about all kinds of information involving the epidemic and choose to read information sources from professional and authoritative departments to reduce the influence of uncertain information. In addition, like the need to monitor body temperature during an epidemic, blood glucose monitoring is a very important part of a sugar patient’s life. By testing blood glucose, it can help determine the effect of treatment, changes that occur in blood glucose, and facilitate timely adjustment of treatment plans. When should sugar lovers test their blood glucose, and how often should they do so? 1. Patients who inject insulin or use insulin stimulants should be monitored 1-4 times a day. They can choose to monitor before meals, two hours after meals and at bedtime; 2. Type 1 diabetic patients should measure blood sugar at least three times a day; 3. Type 2 diabetic patients with good blood sugar control should monitor blood sugar 1-2 days a week; 4. Patients with poor and unstable blood sugar control should monitor blood sugar daily until blood sugar is controlled. If patients with poor blood sugar control or repeated hypoglycemia are found, it is recommended to keep records at home and get in touch with the doctor in time, including the nearest clinic, telephone communication or internet consultation, etc., to make simple adjustments first to ensure the special period and spend it safely.
