What is your sequela of COVID-19?

COVID-19's common sequelae include pulmonary fibrosis, mild decline in cardiopulmonary function, fatigue and decreased labor ability and exercise tolerance caused by muscle weakness.

It can also cause mild psychological disorders, such as insomnia, anxiety or depression.

Serious sequelae can include severe pulmonary dysfunction, respiratory failure, liver dysfunction, renal insufficiency, and even damage to heart function, including various arrhythmias, myocardial ischemia and cardiac insufficiency.

The severity of sequelae of COVID-19 depends on the patient's previous illness. For mild patients, there are generally no sequelae that affect daily life, but for severe patients, it may seriously affect the quality of life.

After rehabilitation, critically ill patients may have a slight decline in liver function or renal function, and some patients may also have long-term sequelae such as loss of smell and taste, limb fatigue and anxiety. If hormone shock therapy is widely used in the treatment, it may also lead to sequelae such as osteoporosis and avascular necrosis of the femoral head due to the large use of hormones. Generally speaking, the probability of sequelae after COVID-19's cure is low, which mostly occurs in critically ill patients, and most of them are mild or asymptomatic infections. The course of disease is short, the treatment time is relatively short, and there is no sequelae after recovery.

However, the treatment period of critically ill patients is long, the lung function is seriously damaged, and the period of medication or hormone application is long, which is easy to cause various sequelae of infected people. Therefore, once COVID-19 is diagnosed, he needs early treatment. Most people infected with COVID-19 have mild or no symptoms, and there will be no sequelae. In severe cases, sequelae such as decreased cardiopulmonary function and neurological symptoms may occur.

1. Decreased cardiopulmonary function: COVID-19 mainly attacks human lung cells and myocardial cells. In severe patients, COVID-19's attack on lung will cause interstitial lung injury, while hypoxia will lead to myocardial hypoxia injury and inflammation aggravation, which may lead to cardiac complications such as arrhythmia.

2. Nervous system symptoms: Many critically ill patients will have nervous system symptoms during their illness, and they will also have nervous system abnormalities after their rehabilitation in COVID-19. The most common symptoms are decreased sense of smell and taste, and other nervous system symptoms such as cognitive impairment, tremor and sensory defects may also occur. However, it is uncertain whether there will be sequelae after COVID-19 infection. If you are infected with COVID-19, you should actively seek help, don't hide it, and do personal protection to avoid the spread of the disease.

After COVID-19 was infected, the target organ was mainly lung. Some patients have severe lung injury, and a few patients may have sequelae of pulmonary fibrosis after recovery, which is one of the more common sequelae.

Severe COVID-19 may also have sequela of pericarditis, and there may be discomfort symptoms such as chest tightness, chest pain and nausea in clinic. It is a new infectious disease, and it is still in the epidemic period. Long-term sequelae of COVID-19 infection In clinical observation, there may be some new sequelae, which need follow-up.

Sequela refers to the defect or dysfunction of some tissues and organs left after the condition has basically improved. At present, although novel coronavirus is highly contagious, its pathogenicity is very weak, and it usually won't cause sequelae after being cured. Most of the patients infected with novel coronavirus are asymptomatic or mild, with fever, cough, sore throat and other upper respiratory symptoms as the main manifestations, and generally do not involve other human systems.

The drugs used in patients' symptomatic treatment generally do not cause sequelae, so patients do not have to worry too much. It is inevitable that you will feel a little tired during the recovery period. It is suggested to take more rest, keep indoor air circulation, and ensure adequate sleep and balanced nutrition. At present, the medical community has not confirmed that novel coronavirus will cause sequelae in patients. Some patients may say that after recovery, there are problems such as olfactory disorder, taste disorder and brain fog.

1. Olfactory disorder: novel coronavirus is caused by novel coronavirus infection, and patients may have olfactory disorder after getting sick. Actively cooperate with doctors for treatment. After novel coronavirus is cured, some patients' olfactory dysfunction may not recover immediately, which makes them think they have sequelae of olfactory dysfunction.

2. Taste disorder: Some patients may have taste disorder after illness, and this discomfort may last for a long time. After novel coronavirus turned negative, the taste disorder still didn't fully recover, leaving this sequela for patients.

3. Brain fog: novel coronavirus may also lead to physical fatigue of patients, and may also have some influence on the brain. Some patients say that they have sequelae of brain fog, such as memory loss and inattention. Usually in novel coronavirus, most of them are common and mild, and patients can recover, and the recovery time is about 2-3 weeks. The disease will reach its peak about 1 week after the appearance of novel coronavirus. At this time, the patient's symptoms are serious, and there will be fever, cough, shortness of breath and difficulty breathing.

Generally, after 7- 10 days, the condition will gradually improve. After the appearance of novel coronavirus, the patient's body temperature will drop gradually at first, the cough will be relieved gradually, and finally the dyspnea will be improved. Novel coronavirus's standard of recovery is that the body temperature can be normal for more than 3 days, and the nucleic acid is positive, that is, it can reach the standard.

And there is also an important indicator, which is CT reexamination. Generally, the absorption of imaging is slow, and it can only be absorbed after 2-4 weeks. Therefore, judging the recovery of novel coronavirus mainly depends on symptoms and nucleic acid test results, not on CT.
