Lung Qi Deficiency

Lung Qi Deficiency manifests when chronic illness, overwork, constitutional weakness, or prolonged grief depletes the Lung's qi, compromising its governing of qi and respiration functions. This pattern presents as the body's inability to generate sufficient qi or maintain proper qi circulation, resulting in both respiratory insufficiency and systemic qi deficiency symptoms. It frequently serves as the foundation for more complex Lung patterns and significantly impacts overall constitutional strength.

Clinical Presentation

Shortness of breath, especially on exertion
Weak voice or disinclination to speak
Spontaneous sweating, particularly with minimal activity
Frequent colds or respiratory infections
Chronic cough with clear or white sputum
General fatigue and lack of strength
Pale complexion
Tongue: Pale, possibly with thin white coating
Pulse: Weak (xu), possibly slow

Pattern Differentiation

vs. Lung Yin Deficiency

Lung Yin Deficiency presents with dry cough or blood-tinged sputum, night sweats rather than spontaneous sweating, and five-palm heat. Tongue is red with little coating, pulse is rapid and thin. Lung Qi Deficiency shows clear/white sputum, spontaneous sweating during day, and no heat signs.

vs. Spleen Qi Deficiency

Both patterns share fatigue and weak pulse, but Spleen Qi Deficiency primarily affects digestion with loose stools, poor appetite, and abdominal distension after eating. Lung Qi Deficiency focuses on respiratory symptoms, voice weakness, and spontaneous sweating. Spleen pattern lacks the respiratory focus.

vs. Heart Qi Deficiency

Heart Qi Deficiency manifests with palpitations, chest oppression, and emotional symptoms like anxiety or restlessness. While both show fatigue and weak pulse, Heart pattern lacks the respiratory symptoms and spontaneous sweating characteristic of Lung Qi Deficiency. Heart pattern may include irregular pulse rhythm.

Treatment Principle

Tonify Lung qi, strengthen the Spleen to support qi generation, secure the exterior to prevent pathogen invasion, and regulate qi circulation to restore proper respiratory function.

Frequently Asked Questions

The Lung governs the exterior and defensive qi circulation. When Lung qi is deficient, wei qi becomes insufficient and fails to properly circulate through the exterior, creating vulnerability to external pathogenic invasion. This manifests as repeated respiratory infections and poor recovery from illness.

The Spleen is the source of acquired qi production through transformation of food essence. Lung Qi Deficiency treatment must address Spleen function because weak Spleen qi directly impacts the Lung's qi supply. Tonifying Spleen qi supports long-term Lung qi recovery and prevents pattern recurrence.

Lung Qi Deficiency sweating occurs primarily with physical activity or during daytime, accompanied by shortness of breath and weak voice. It differs from Kidney Yang Deficiency sweating (occurs at night, with cold limbs) and Heart qi/yang deficiency sweating (occurs with palpitations and chest discomfort).

Constitutional cases show lifelong patterns of weak voice, easy fatigue, and frequent respiratory infections from childhood. Acquired cases develop after specific triggers like chronic illness, excessive grief, or overwork. Constitutional cases require longer treatment duration and more attention to Kidney support, while acquired cases respond faster with targeted Lung tonification.
