What should I do if I develop pneumonia in a diabetic patient? The new coronavirus infection pneumonia epidemic has touched the hearts of millions of people, from the recent analysis of confirmed cases, about 1/3-1/2 of the confirmed cases combined with underlying diseases, diabetes is one of the more common known underlying diseases. What about pneumonia in diabetics? The basic requirement of diabetes treatment is to ensure the needs of the body in its physiopathological state and to maintain the balance of glucose metabolism through reasonable nutrition. When the symptoms of pneumonia are severe, the patient often loses his appetite. At this time it is necessary to give a light diet, but also to pay attention to be able to provide sufficient calories. Cooking should be done in a way that is easy to digest, while increasing the intake of fresh vegetables and fruits in moderation. When the patient eats less, the amount of glucose-lowering drugs should be actively adjusted according to the results of blood glucose monitoring to avoid hypoglycemia. However, when the intake of energy-supplying nutrients is high, timely adjustments should be made according to the level of blood glucose to avoid severe hyperglycemia. When a patient has severe pneumonia, medical nutrition therapy should be administered under the guidance of a dietitian, and if necessary, formulated enteral nutrition can be given according to the patient’s condition. In general, exercise is one of the bases of diabetes treatment. However, in the acute phase of pneumonia, excessive exercise is not advocated. Some low-intensity aerobic exercises, such as walking, can be used in patients with mild disease. In the case of combined pneumonia, diet therapy and exercise therapy are very different from the state of daily life. At this time, among the glycemic control, drug therapy becomes especially important. What else do diabetic patients need to pay attention to in the case of new coronavirus pneumonia? First of all, we need to do a good job of psychological adjustment, in the face of the epidemic, we can not take it lightly and do not need to panic, we need to set the right mindset, scientific prevention and control. Pay attention to personal hygiene, bathe regularly, change clothes regularly, wash hands regularly and ventilate regularly. Practice health monitoring, in addition to blood glucose and blood pressure, you should also pay attention to temperature measurement and symptom observation. Diabetic co-infection is often a common trigger of ketoacidosis. Symptoms include irritability, excessive drinking, polyuria, increased symptoms of malaise, and patients may experience nausea, vomiting, abdominal pain, and rotten apple odor on exhaled breath, and in severe cases, they may gradually become unconscious to the point of shock and coma. Another common acute metabolic complication of diabetes is hyperglycemic hyperosmolar coma, which is more common in the elderly or those with combined kidney disease. Patients may also experience irritable thirst, excessive drinking, markedly increased polyuria, and gradually develop signs of mental disturbance such as irritability, restlessness, drowsiness, and delirium.
