Into the winter cold air frequent attacks and dry climate, so that the number of influenza increased sharply, which is suffering from diabetes and other chronic diseases of the population is a test again and again. Many diabetic patients have been hospitalized. Compared with the common cold, flu symptoms are more serious, more contagious, and more harmful to people with chronic diseases such as diabetes. What is worrying is that few diabetic patients know that the flu brings them very serious harm. First, what is the harm of influenza to diabetic patients? 1, leading to an increase in stress hormones in the body, these hormones can antagonize the glucose-lowering effect of insulin, resulting in increased blood glucose, the original blood sugar control is more stable people can be deteriorated because of influenza, and the original blood sugar is higher people may become higher, and even diabetic ketoacidosis and other acute complications, and even death; 2, induced by the aggravation of lung infections, the patient’s health hazards are even greater. Although some pneumonia can be treated with the help of antibiotics, but due to the overuse of antibiotics in recent years, resulting in varying degrees of drug resistance, the result is a long treatment process, increased treatment costs, in the treatment process is prone to secondary infections (fungal infections) to further aggravate the condition. Second, why are diabetic patients prone to influenza? Poor glycemic control will increase the risk of influenza, and influenza will also make it more difficult to control blood glucose, thus forming a vicious circle. Poor glycemic control in diabetic patients reduces protein synthesis and increases digestion, which also reduces the production of immunoglobulin and complement, which are anti-viral substances. High blood sugar can also cause glycosylation of immunoglobulins, inhibiting the ability of white blood cells to phagocytose and remove microorganisms, and reducing the body’s resistance to influenza virus infection. In addition, diabetic patients with vascular complications have poor blood flow, and insufficient blood supply to various organs and tissues of the body will further weaken the body’s ability to resist influenza virus. At the same time, diabetic patients in the body of high blood sugar environment is also conducive to the growth and reproduction of viruses and other pathogenic microorganisms. Third, how to prevent influenza in diabetic patients? 1.Keep indoor air fresh to prevent bacteria from breeding. Open the windows frequently to let the air circulate. 2, maintain good personal habits and personal hygiene, dry clothes and bedding, wash your hands often, wash and disinfect household items often. 3, maintain sufficient sleep, more exercise, but also to maintain a healthy and good state of mind. Do not always stay up late, actively participate in physical exercise, increase resistance, improve their immune function. (Usually pay attention to strengthen physical exercise, improve physical fitness, strengthen the ability to exercise cold, such as running in the morning, climbing, etc.) Try to minimize the public crowded places, easy to be infected with influenza virus, you can consider wearing a mask to reduce the possibility of wind-borne transmission. 4, do not share towels, handkerchiefs and eating utensils. If there is a flu patient at home or at work, we must wash our hands after touching their public goods before doing anything else, and never touch our eyes, nose and mouth without washing our hands and other susceptible parts of the body. 5, according to the seasonal changes in time to increase or decrease clothing, etc., to prevent influenza is very good. You can also wash your face with cold water to strengthen your resistance. 6.Influenza vaccination: it can reduce the chance of infection in diabetic patients, reduce medical costs, and lower the morbidity and mortality rate. This is a better way to prevent influenza in diabetic patients. Therefore, diabetic patients should follow the recommendations of the diabetes treatment guidelines, and actively inject the flu vaccine before the arrival of influenza every year. The best time to get a flu shot is from September to December. 7. During the influenza epidemic, it is advisable to have a light diet and eat easily digestible foods rich in vitamins. At the same time, we should pay attention to drinking more water, mainly plain water, drinking more water can reduce the symptoms of poisoning and shorten the course of the disease. It is better not to eat salty food, after consuming salty food, it is easy to make the mucous membrane of the disease-causing area contract, aggravate nasal congestion, throat discomfort and other symptoms. Too salty food is easy to produce phlegm, stimulate the local cause of cough aggravation. It is also not easy to eat hot, sweet, barbecue fried food, and should avoid smoking and alcohol. 8, during the epidemic, if there is a high fever does not go away, cough, pus sputum, difficulty in breathing and other influenza-like symptoms should be timely medical care.
