Dr. Zhang Xiuhong

Phlegm-damp constitution is characterized by symptoms such as obesity, oily facial skin, thick greasy tongue coating, chest tightness and abdominal distension, excessive phlegm, and coughing.

1. Obesity: Individuals with a phlegm-damp constitution are often obese, particularly with a soft, protruding abdomen, and may also experience swelling in the limbs. This is due to the accumulation of phlegm-damp in the body, which causes disturbances in fat metabolism.

2. Oily facial skin: Those with a phlegm-damp constitution often have oily facial skin, enlarged pores, and are prone to acne and pimples. This is caused by internal accumulation of phlegm-damp, which affects the circulation of qi and blood as well as fluid metabolism, leading to excessive sebum secretion.

3. Thick greasy tongue coating: Individuals with a phlegm-damp constitution typically exhibit a thick, greasy tongue coating, which may appear white or slightly yellow. The tongue body is often swollen with tooth marks along the edges. This is a manifestation of phlegm-damp accumulation on the tongue surface and is a typical tongue sign of this constitution.

4. Chest tightness and abdominal distension: People with a phlegm-damp constitution frequently experience chest tightness and abdominal distension, with symptoms worsening after eating. This is caused by phlegm-damp obstructing qi circulation and impairing the digestive functions of the spleen and stomach.

5. Excessive phlegm and coughing: Those with a phlegm-damp constitution are prone to coughing with abundant thick phlegm that is white or yellowish in color. This occurs due to phlegm-damp blocking the lungs and impairing normal lung function. Occasionally, symptoms such as chest tightness and shortness of breath may also occur.

The development of a phlegm-damp constitution is associated with multiple factors, including irregular eating habits, lack of physical activity, congenital constitution, aging, chronic illness, and invasion of cold-damp pathogens. Managing a phlegm-damp constitution requires a comprehensive approach, including adjusting dietary habits, increasing physical exercise, and maintaining emotional well-being.
