Introduction
In adults, jaundice causes yellowing of the sclera, oral mucosa, skin, and other areas. The sclera contains elastin, which has a strong binding affinity for bilirubin, leading to yellow discoloration of the sclera. Accumulation of bilirubin in the body results in yellowing of the skin and mucous membranes, such as the oral mucosa. Elevated levels of bilirubin in the body cause skin yellowing. In addition, it may also lead to yellow discoloration of urine and stool.

Jaundice in adults usually causes yellowing of the sclera, oral mucosa, skin, and other areas.

1. Scleral yellowing

The sclera contains elastin, which has a strong binding affinity for bilirubin. When bilirubin levels in the body become too high, it binds to elastin, resulting in yellowing of the sclera.

2. Oral mucosal yellowing

When bilirubin accumulates in the body, it often leads to yellow discoloration of the skin and mucous membranes, such as yellowing of the oral mucosa.

3. Skin yellowing

Elevated bilirubin levels in the body can easily cause skin yellowing, initially appearing on the face, palms, and soles of the feet.

In addition, it may also cause yellow discoloration of urine and stool.
