Signs of illness often show on our faces. As the saying goes, "To gauge health, look at the face." The face is not only a stage for emotions—it can also reflect internal health problems. Watching for facial changes can be a simple way to spot potential issues early.

1. Acute illness appearance: Flushed skin, rapid breathing, flared nostrils, a pained expression, and restlessness. In TCM, this may correspond to conditions such as lobar pneumonia or malaria.

2. Chronic illness appearance: A gaunt look, dull or pale complexion, lackluster eyes, and fatigue. In TCM, this suggests weakened vital energy; in Western medicine, it is often linked to chronic wasting illnesses such as malignancy, chronic hepatitis, liver cirrhosis, or tuberculosis.

3. Anemia appearance: Pale skin; pale lips and tongue; fatigue; and shortness of breath. In TCM, this reflects a deficiency of qi and blood; in Western medicine, it is commonly associated with anemia.

4. Hyperthyroidism appearance: Bulging eyes, retracted eyelids with a startled stare, yellowish skin, a thin build, and signs of agitation and irritability. In TCM, this is attributed to liver qi stagnation transforming into heat, with insufficient liver yin and excessive liver yang; in Western medicine, it is typical of hyperthyroidism.

5. Hypothyroidism appearance: Also called a myxedema appearance, it features pale or sallow skin, a dull gaze, facial puffiness, thick lips and tongue, thickened eyelids, dry and inelastic skin with few but deep wrinkles, sparse and brittle hair, and noticeable thinning of the eyebrows. In TCM, this suggests spleen qi deficiency and kidney yang deficiency; in Western medicine, it is often linked to hypothyroidism. Similar features can also be seen after castration or with pituitary dysfunction.

6. Acromegaly appearance: An enlarged head, elongated face, protruding jaw, prominent cheekbones, pronounced brow ridges, enlarged ears and nose, thickened lips and tongue, and widened tooth spacing. This pattern is characteristic of acromegaly.

7. Mitral valve appearance: Also called the rheumatic heart disease appearance, it includes a sallow, puffy face; dark red cheeks; bluish lips; a dark tongue; along with palpitations and shortness of breath. In TCM, this reflects blood stasis in the heart due to heart qi and yang deficiency; in Western medicine, it is commonly seen in rheumatic heart disease, particularly mitral stenosis, and may also appear in pulmonary heart disease or certain congenital heart defects.

8. Typhoid appearance: Sluggish responses, an apathetic expression, a red tongue with scant coating, shortness of breath, and even altered consciousness. In TCM, this indicates a deficiency of both qi and yin and is classified among warm diseases; in Western medicine, it may be seen with typhoid fever, meningitis, or encephalitis.

9. Tuberculosis appearance: Pale skin with rosy cheeks and weight loss. This is commonly seen during active pulmonary tuberculosis.

10. Moon face: A round, puffy face resembling a full moon, where the ears may be obscured from the front and the nose may be less visible from the side. Fat accumulation in the cheeks can pull the nostrils downward, make the mouth look smaller, and create deep grooves between the mouth corners and cheeks. The complexion may be rosy, with increased fine facial hair, frequent acne, and small mustaches on the lips. In Western medicine, this is characteristic of Cushing’s syndrome or excessive corticosteroid use.

11. Nephrotic edema appearance: Pale, swollen skin with tight, dry texture; especially prominent eyelid swelling in the morning; and indentation marks on the forehead after pressure. Similar facial swelling can be seen in heart failure, malnutrition, facial neurovascular edema, severe asthma, and whooping cough.

12. Adenoid appearance: Mouth breathing; underdeveloped nasal shape; a flat nasal bridge with small nostrils; thick, short lips; an upturned upper lip; shallow nasolabial folds; an underdeveloped jaw; unclear speech; reduced hearing; and a vacant expression. This pattern is seen in children with adenoid hypertrophy.

13. Critical illness appearance: A gaunt face; pale or lead-gray complexion; flat affect; vacant gaze; sunken eyes; a prominent nose; and cold extremities. In TCM, this suggests loss of yin or yang; in Western medicine, it is often associated with severe hemorrhage, shock, dehydration, and other critical conditions.

14. Leonine facies: In lepromatous leprosy, the face may develop uneven nodules and patches, with partial or complete loss of the eyebrows, eyelashes, body hair, and beard, creating a “lion-like” appearance. A bony leonine appearance may also be seen in fibrous dysplasia, inflammation of the cranial membranes, deforming osteitis, or after trauma.

15. Myopathy appearance: Difficulty fully opening or closing the eyes (often half-open), inability to frown, thick protruding lips, and a drooping lower lip that makes it hard to close the mouth. This can be seen in muscular dystrophy or myasthenia gravis.

16. Congenital intellectual disability appearance: A high forehead; upward-slanting eyes; bulging or crossed eyes, or nystagmus; and a flat nasal bridge with upturned nostrils.
