The epidemiological situation of novel coronavirus is getting more and more severe, and the prevention and control work is still in a difficult period. From the limited information available, serious clinical events due to novel coronaviruses are mainly concentrated in people aged 40-60 years, many of whom are elderly, have underlying diseases and are obese. In the case of diabetic patients with long duration of disease, due to the possible combination of macrovascular or microvascular complications, resulting in reduced blood supply to the distal extremities, once the infection occurs, the anti-infective substances in the body cannot reach the infection site smoothly, which is not conducive to the control of local infection and is prone to spread. Especially for those who have poor blood sugar control, once the infection occurs, the consequences are usually more serious and may even induce acute complications of diabetes, and those who have poor infection control may even be disabled or die, so this is definitely not a trivial matter. Therefore, it is important for sugar lovers to fight the battle against the new coronavirus and protect themselves well. In order to help sugar lovers spend the epidemic period safely at home, the following warm tips must be kept in mind: 1. Avoid going out and strengthen protection Based on good blood sugar control, strengthening self-protection is the most important thing to effectively prevent serious infections. During the epidemic prevention and control period, it is recommended to reduce going out, avoid crowd gathering places, and keep indoor air circulation (note that it is currently winter, so avoid colds caused by excessive changes in indoor temperature). Second, reasonable diet and balanced nutrition. Medical nutrition therapy is the basic treatment of diabetes. Diabetic patients need to maintain stable blood sugar and enhance body resistance. During the epidemic prevention and control period, which is the Chinese New Year festival, it is more important to pay attention to reasonable diet and balanced nutrition. Third, moderate exercise to enhance physical fitness. Exercise plays an important role in the lifestyle management of diabetes. During the current critical period of epidemic prevention and control, as it is recommended to reduce going out and avoid contact, it is recommended that diabetic patients carry out appropriate exercise at home. Fourth, regular work and rest, and keep a happy mood. Patients with diabetes should work and rest reasonably, do not stay up late, do not work too hard, and maintain a good sleep. A reasonable work and rest routine can avoid a decline in resistance. Five, adhere to the standardized use of medication according to medical advice. We suggest that diabetic patients can take their medication at the community health center near their home during the epidemic prevention and control period, and must follow the doctor’s instructions to treat them on time and in the right amount. During this special period, it is crucial to regularly and consistently standardize medication according to medical advice. Sixth, regular blood glucose monitoring to keep blood glucose stable. Blood glucose monitoring is an important part of diabetes management and regular monitoring is recommended for diabetic patients. During residence, patients treated with oral medication are recommended to monitor fasting or 2-hour postprandial blood glucose 2-4 times a week during the epidemic prevention and control period regular blood glucose monitoring can avoid acute complications and other adverse events caused by hyperglycemia or hypoglycemia. VII. Raise vigilance to prevent acute complications. Patients with diabetes are advised to take their body temperature and observe for appropriate symptoms daily. Infection is a common trigger for diabetic ketoacidosis and hyperosmolar coma. If symptoms such as nausea, vomiting, abdominal pain, rotten apple smell in the breath, increased fatigue and irritability, irritability and drowsiness occur, you should seek medical attention immediately after taking protective measures such as wearing a mask. Faced with the epidemic correct mindset, both to pay attention to, but not panic. In addition to wearing masks and taking care of hygiene, it is also important to maintain an optimistic mindset. It is recommended to keep telephone or video communication with family and friends to share your physical and mental condition. Always stay calm, do not believe in internet rumors and do not blindly forward unofficially confirmed information news to avoid panic and spreading panic.
