As mentioned in the Quick Guide to the Treatment of Novel Coronavirus Pneumonia, patients with novel coronavirus are currently concentrated among middle-aged and elderly people aged 40-60 years old; critical illness accounts for about 15%, and most of them are elderly people, people with underlying diseases and obese people. Glucose and fat people are the most severely injured group in the new coronavirus due to their low immunity. For them, the way to improve immunity is to effectively treat the underlying disease and lose weight. Can weight loss and metabolic surgery improve immunity? Bariatric surgery addresses the root cause of food intake and nutrient absorption, and not only reduces weight, but also treats a variety of metabolic diseases associated with obesity, such as type 2 diabetes, hypertension, etc. When the underlying diseases are treated, the body’s organs function well and immunity is naturally enhanced. Studies indicate that patients who undergo weight loss surgery can live an average of 7 years longer after surgery compared to obese people who do not undergo weight loss surgery. Is there anything I need to know if I want to have weight loss surgery after the epidemic? First, do you meet the indications for bariatric surgery. Weight loss surgery, not just anyone can do, has relatively strict indications for surgery, and only people who meet the criteria can have the surgery. Second, under the condition of meeting the indications, if you want to do weight loss metabolic surgery, you also need to take into account the current epidemic situation. After this epidemic, I believe we all understand how important health is. Patients who meet the indications for surgery can choose bariatric surgery to improve immunity and physical fitness if necessary, and for patients with severe obesity, the significance of bariatric surgery is even life-saving. All of our medical and nursing staff, in the face of the severe epidemic, held their positions and were with the patients on the clinical front line.
