How long it takes to recover from Qi deficiency depends on the cause of Qi deficiency, the patient’s age, gender, the presence or absence of underlying diseases and severity, and other factors, and cannot be generalized. Qi deficiency is generally characterized by a waxy complexion, poor appetite, general weakness, easy cold sweating, and in severe cases, dizziness. Qi deficiency is generally divided into four types: Lung Qi deficiency, Spleen Qi deficiency, Kidney Qi deficiency and Heart Qi deficiency, with different recovery times for different Qi deficiencies. In general, patients with qi deficiency can gradually recover after 1-2 months of conditioning with Chinese herbal medicine. Severe qi deficiency can lead to a decrease in body resistance and immunity, and the recovery time can be extended accordingly. In addition, patients with Qi deficiency are advised to avoid eating cold, spicy and greasy food, and to consume more nutritious and easily digestible food, as well as to pay attention to rest, avoid straining, engage in moderate physical activity and keep a happy mood.
