During the COVID-19 epidemic, many severely ill patients are middle-aged and elderly people. Middle-aged and elderly people suffer from a variety of diseases, their body organs are reduced in function, and their chewing and swallowing functions are reduced, leading to insufficient food, and they are prone to weight loss and malnutrition before being infected with the virus. The weight loss and malnutrition will lead to a decline in immune function and will not be able to withstand the blow of virus infection. Therefore, the elderly must increase their nutritional reserves through reasonable nutritional supplements, especially increasing muscle content, so as to improve their immunity.
In view of the inconvenience of the elderly, it is sometimes difficult to prepare nutritious foods. At the same time, the appetite of the elderly decreases and it is difficult to meet the daily calorie and nutritional needs. It is recommended to choose the following oral nutritional supplements: oral total nutritional supplements; multi-vitamin and mineral supplements; high-quality protein supplements. Each of these three nutritional supplements has many brands and specifications. You can choose one of them separately and use them together. When the weight of the elderly slowly rises, it means that the immunity is also improved. Of course, nutritional supplements are best purchased at medical institutions and used under the guidance of a doctor.
Then, what should be paid attention to in a reasonable diet? A balanced diet, paying particular attention to the intake of high-quality protein (milk, eggs, soy products, meat) and fresh vegetables and fruits; appropriate supplementation of nutrients, such as protein, unsaturated fatty acids such as fish oil and linseed oil, and a diet that regulates intestinal immune function Fiber and multivitamin and mineral supplements, etc.; to avoid obesity and increased blood sugar caused by reduced activity in the short term. Controlling body weight and blood sugar is especially important for maintaining the immune function of obese and diabetic patients. For obese patients, if too little exercise, blood viscosity increases, it will increase the occurrence of embolic diseases, such as stroke, myocardial infarction and pulmonary embolism; avoid weight loss and weight loss, because malnutrition directly leads to immune function decline; Avoid smoking and drinking, increase exercise appropriately, but avoid going to crowded places, and also avoid going to relatively closed gyms.

After sitting at home for a long time, do you feel that your lower limbs are swollen? Then you might as well follow this set of plantar and lower limb training methods recommended by the State Sports General Administration.

This action can relax the plantar fascia, activate the plantar muscles, and improve the flexibility of the ankle joint.
The second set of moves, raise your legs and heels. This action is divided into walking with knees and hips, external rotation with knees and hips, and walking with knees and hips extension.
Bend the knees and bend the hips to keep the upper body upright. When moving forward, hold the knee joint of the raised leg with both hands, keep the knee joint as close to the chest as possible, support the foot, raise the heel, and move forward with the heel raised. .
The essentials of external rotation walking with knees bent and hips are as follows.

A few days ago, some media reported that due to the impact of the epidemic environment, the elderly had a high incidence of deep vein thrombosis. This disease, which is very common in clinical practice, has caused heated discussions on the Internet.
”Deep vein thrombosis is a disorder of venous return caused by abnormal blood clotting in deep veins. It often occurs in the lower extremities and is also a very common disease.” Sun Peng, Director of Vascular Surgery and Chief Physician, Affiliated Hospital of Yangzhou University Said the doctor.
Sun Peng introduced that the main causes of deep vein thrombosis are vein wall damage, slow blood flow and hypercoagulable blood. The risk factors for disease include primary factors and secondary factors. The primary factor is that there are more components that promote blood coagulation and fewer components that dissolve thrombus. If it is a deep vein thrombosis caused by primary risk factors, it may be necessary to take some anticoagulant drugs for a long time to fight the disease. Secondary risk factors include major surgery or severe trauma, long-term bed rest, limb immobilization, cancer patients, and increased blood viscosity.
Regarding the recent high incidence of deep vein thrombosis in the elderly, Sun Peng said that when the temperature is still cold, the temperature is still low. After the human body is stimulated by the cold, the capillaries all over the body contract, and the lack of exercise due to the epidemic. Severe obstruction of blood flow can easily lead to poor blood flow and thrombosis.
”The main hazards of deep vein thrombosis include: causing leg swelling, which leads to limb necrosis; often causing pulmonary embolism, which may lead to death; later, it can lead to post-thrombotic syndrome, causing long-term leg swelling and affecting the patient’s life Quality.” Sun Peng said.
Mao Youjun, director of the Department of Vascular Surgery, Changzhou Second People’s Hospital, said that thrombosis is not just a disease of the elderly. It can occur at any age and at any time. “When spreading to the proximal end, the thrombus may fall off, and then flow along the direction of the blood flow to the heart. If it returns to the pulmonary artery, there will be a large thrombosis and block the pulmonary artery, which will lead to a higher mortality rate. Some The patient is likely to die suddenly.” Mao Youjun said.
Introduced by Mao Youjun, a few days ago, when an elderly male patient came to the hospital for treatment, his left leg was swollen and red, and the pain was unbearable when he touched it. After a B-ultrasound, he was diagnosed with deep vein thrombosis. The doctor immediately treated the patient Surgery was taken. “We learned during the consultation that the main predisposing factor for this patient’s deep vein thrombosis was that before the outbreak, he would go out to buy groceries, walks, and participate in some outdoor sports. However, affected by the epidemic, he stayed at home for nearly one. For many months, I haven’t even gotten off the building.” Mao Youjun said.
Mao Yujun said that similar patients who lack proper exercise to induce deep vein thrombosis have recently been more concentrated. Some of these patients were watching the TV, some were sitting in front of the computer with their eyes open, and some were lying in bed for a long time. They often stayed in a posture and sat for several hours, causing swelling of their legs and thrombosis. .
Experts believe that the prevention of deep vein thrombosis must be highly valued from many aspects, develop a good and healthy lifestyle, achieve early prevention, early detection, early inspection, and early treatment, timely control of the disease, and prevention of complications.
Sun Peng specially reminded that if symptoms such as swelling, pain, numbness, instability of the lower limbs are found, even accompanied by dyspnea, chest pain, hemoptysis, etc., they should seek medical examination and treatment as soon as possible for drug prevention and physical prevention.
