The symptoms of lung qi deficiency are many, and the expression “seven major manifestations” is inappropriate. Lung qi deficiency is often characterized by weak cough, sputum, low voice, tiredness of the limbs, and fatigue. Lung qi deficiency, also known as lung qi insufficiency, due to lung qi insufficiency, unable to promote and regulate breathing, transmission and distribution of water and liquid, spreading the Wei qi, resulting in the pathological changes of the body’s defense role is reduced. Clinically, it is often manifested as weak cough, sputum, pale color, low timid voice, tiredness of limbs, fatigue, self-sweating (involuntary sweating during the day, a little sweat aggravated by movement), fear of wind and other symptoms. The occurrence of lung qi deficiency is related to factors such as insufficient endowment (poor innate constitution and functioning), internal injuries due to accumulated labor, coughing and wheezing due to prolonged illness, and old age and frailty. The disease usually starts slowly and lasts for a long time. If the doctor clearly identifies the symptoms and the patient is actively treated, the prognosis is generally good. If the disease is not treated in time, it can lead to deficiency diseases (qi deficiency, blood deficiency, yin deficiency and yang deficiency, etc.) as the disease progresses. If you suspect that you are suffering from lung qi deficiency, you should consult a doctor in time and actively cooperate with the doctor’s treatment.
