Where does jaundice appear in adults?
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.
