  The new coronavirus enters our host cells through ACE2, the angiotensin-converting enzyme 2 receptor.

Its distribution is very wide, of course our main affected is our lungs, but other organs can still be affected.

After we get a disease, our organ virus attacks it, and it takes a while to repair it.

Before it is repaired, its function and its state may not be in an optimal state, so many patients will have such symptoms.

  For patients with relatively mild lesions, or those who have not accumulated in the lungs, and those who have not suffered damage such as viral myocarditis, generally speaking, I think they should basically be able to recover within three to four weeks. to one level of baseline.

For the vast majority of mild and normal patients, basically our lungs have a very strong repair ability and can return to normal, so I don’t think there is any need to worry.

When we were in Wuhan, I saw the recovery of critically ill patients under our management. We made a return visit in 2 to 3 years later, and most of the patients who were in serious condition could recover to their usual condition. A state of seventy to eighty percent of physical fitness.

  [3] How to self-diagnose if you feel unwell? Do you need to seek medical treatment?

  If you have the conditions, you can have an instrument for monitoring finger pulse oxygen, that kind of simple finger pulse oxygen meter that is very simple to put on your finger, can monitor our finger pulse oxygen and heart rate.

Finger pulse oxygen can be stabilized above 95%, and his heart rate can basically be stabilized between 60-100 beats per minute. In this case, there is no need to be too nervous. This shows that even if you have new coronary pneumonia, Its lesions are also very small and do not require special treatment. Most of the treatment is symptomatic treatment, so it is not necessary to have a CT scan.

If there is a drop in blood oxygen saturation, it often indicates that the area of ​​your lung lesions is relatively large, and you must see a doctor in time.

  For people without risk factors, it is a good indicator to seek medical treatment based on finger pulse oxygen and heart rate.

But for people with high-risk factors, especially the elderly, in addition to monitoring finger pulse oxygen and heart rate, their mental state needs to be observed at the same time.

The new crown sometimes manifests as silent hypoxia, which means that the patient does not feel that he has difficulty breathing, but in fact, if it is monitored, it may be abnormal in finger pulse oxygen.

Therefore, if the monitoring is not in place, attention should also be paid to the patient's mental state.

If you have a bad mental state or even a change in consciousness, you need to see a doctor in time.

  Take a proper rest and don't be too tired, and it can't be said that you need to lie on the bed completely, no need, but don't engage in strenuous exercise.

Then there is a nutrition of the diet. In terms of nutrition, we advocate vitamin-rich and protein-rich foods, and do not advocate irritating foods and foods with high fat.

I think eggs are a good food, and then there is white meat chicken. It is better if you can remove the skin of the chicken, because the fat of the chicken skin is still relatively high, and fish is also a good source of protein.
