[Explanation] The new crown pneumonia epidemic continues to rages, and global academic institutions have gradually deepened research on the new crown virus.

A few days ago, a new study by the Faculty of Medicine of the Chinese University of Hong Kong found that about 80% of patients with new coronary pneumonia who participated in the study continued to show symptoms after recovery.

The intestinal microecological status is closely related to the severity of the disease.

Even if the virus in the patient's body has been cleared, the imbalance of the intestinal microecology may lead to a series of long-term symptoms. This condition is called "long-term new crown" or "new coronary pneumonia sequelae."

　　Approximately 75% of patients with new coronary pneumonia will continue to have related symptoms after recovery. This situation is also the "prolonged new crown" problem we have just mentioned, including the most common fatigue, muscle pain, breathing difficulties and so on.

　　[Explanation] Research shows that “long-term new crown” refers to symptoms that last more than 12 weeks after recovery from new crown patients. The five most common symptoms include fatigue, poor memory, insomnia, difficulty breathing, and hair loss.

According to reports, the Faculty of Medicine of CUHK followed up on the condition of 30 patients with new coronary pneumonia six months after the infection, and found that about 80% of the patients still had related symptoms, and one third had more than three symptoms.

Chen Jialiang, dean of the Faculty of Medicine of the Chinese University of Hong Kong, said that studies have shown that these symptoms may be related to the imbalance of the patient's intestinal microecological.

　　First, from our research, we found that the intestinal microbiota regulates our immune capacity.

And the second point is that our latest research has found that the lack of beneficial bacteria in the gut microbiota of patients with COVID-19 that can regulate our immunity is closely related to the severity of our disease.

The third point is that even though our patient’s virus has been cleared, his intestinal microecological imbalance will continue and may lead to long-term symptoms. This situation is called "Changing Coronavirus".

Therefore, we are now committed to studying how to improve the intestinal microecological imbalance by adjusting and improving the intestinal microecological imbalance to help these patients with new coronary pneumonia reduce the risk of "long-term new crown".

　　[Explanation] Chen Jialiang said that improving the intestinal microecology will help improve human immunity, reduce the risk of contracting new coronary pneumonia, and will also improve the sequelae of patients with new coronary pneumonia to a certain extent.

Chen Jialiang gave several suggestions on how to improve the intestinal ecological environment.

　　First, it is indeed easier for children to change than adults, especially the elderly.

Second, we have a few foods that we want to avoid. We do need to avoid some additives and sugar substitutes. The third is unnecessary antibiotics, because these three types of foods or drugs will destroy the ecology of our intestines and will also Directly make our intestines have a chronic inflammation.

The third aspect is that exercise is indeed very important. Many years of research have shown that regular aerobic exercise can improve our intestinal microecology.

The fourth aspect is that I do not agree with the general public who blindly take some health products.

　　[Explanation] The research team said that the current clinical data shows that supplementing the beneficial bacteria lacking in the intestine can relieve the disease and promote antibody production. The team is currently studying the use of improving the intestinal microecological imbalance to reduce the "new coronary pneumonia sequelae" in patients. risks of.
